As a body cell grows, the ratio of _______ to volume _________. Before it grows to large, a cell will divide into two ________ cells. So that each new cell receives its own genetic instructions, the cell ________ or copies, all of its DNA.
Answers
Answer: As a body cell grows, the ratio of SURFACE AREA to volume INCREASES. Before it grows to large, a cell will divide into two DAUGHTER cells. So that each new cell receives its own genetic instructions, the cell REPLICATES or copies, all of its DNA.
Explanation:
As a body cell grows, the ratio of surface area to volume decreases. Before it grows to large, a cell will divide into two daughter cells. So that each new cell receives its own genetic instructions, the cell replicates or copies, all of its DNA.
The volume of a growing cell increases at a larger pace than the surface area. Hence the ratio of the surface area to the volume of the cell keeps decreasing. At a certain point, the signal to divide is given and this leads to the division of the cell into two daughter cells.
Just before the division, the genetic material of the cell is replicated and other important biomolecules are synthesized before the final call can be made.

What are some examples of suitable environments for bacteria?
How might bacteria avoid dying if an environment is not suitable?
How are bacterial cells different from plant and animal cells?
Describe how bacteria reproduce. How can bacteria acquire new characteristics?
Answers
Answer:
bacteria are found everywhere even in hot springs. Bacteria are different from other organisms because they don't have membranes bound organelles .they replicates to produce
Explanation:
Bacteria can live in hotter and colder temperatures than humans, but they do best in a warm, moist, protein-rich environment that is pH neutral or slightly acidic. There are exceptions, however some bacteria thrive in extreme heat or cold, while others can survive under highly acidic or extremely salty conditions.
How might bacteria avoid dying if an environment is not suitable?Many types of bacteria, if environmental conditions become unfavourable (lack of water, increase in temperature, etc), will go into a sort of dormant state, called an Endospore.
How are bacterial cells different from plant and animal cells?Because bacteria are prokaryotic, they do not have a nucleus and no membrane-bound organelles. In contrast, plants and animals are made up of eukaryotic cells, which means they have a nucleus and membrane-bound organelles like mitochondria or Golgi apparatus.
Describe how bacteria reproduce. How can bacteria acquire new characteristics?Bacteria reproduce through a process called binary fission. During binary fission, the chromosome copies itself, forming two genetically identical copies. Then, the cell enlarges and divides into two new daughter cells. The two daughter cells are identical to the parent cell.

Answers
Answer: Wild hamsters like to sleep in underground burrows.
Explanation:
Wild hamsters are found throughout Europe and Asia. The wild hamsters are nocturnal and have bad eyesight.
They navigate through their sense of smell and touch, also with their whiskers.
Wild hamsters like to live in warm and dry areas such as deserts.
They would like to sleep in underground burrows which are series of tunnels to live and to breed. Living underground makes the wild hamsters cool in hot climates.
Hence, Wild Hamsters like to sleep in underground burrows.
Because transfer need a lot of space and in the wild hamster are good diggers and construct deep dark underground burrows

Which is not a characteristic of an early succession plant?
A.) produces lots of seeds
B.) the seeds germinate best in shade
C.) small in size
D.) short-lived
Answers
Early succession plant has a characteristic of producing a lot of seeds, smaller size and short lived. Therefore, the correct statements are option A, option C and option D.
What are early succession plants?Early succession plants are plants that quickly adapts in areas that have been recently cleared and have harsh environments. These plants can easily grow in areas having low soil fertility, lack of water and high exposure to sunlight.
These plants produce a lot of seeds, are smaller in size, and short lived. High reproductive capacity, fast growth, tolerance to harsh conditions, short life cycles are other characteristics of an early succession plant.
Weeds like dandelions, annual rye grass and shrubs like fireweed are some of the examples of early succession plants. These plants have also the ability to fix nitrogen in the soil to improve the soil quality for plant growth. However, their seeds do not germinate best in shade.
Therefore, early succession plants produce lot of seeds, smaller in size and short lived.

2. What are some examples of nonliving things in an ecosystem?
3. What are some factors that could affect the number of organisms in an ecosystem?
4. Why might organisms interact in an ecosystem?
5. Would you expect to find the same kinds of interactions between organisms in very different ecosystems? Why or why not?
6. Why is it important to understand feeding relationships in an ecosystem?
Answers
Examples of nonliving things in an ecosystem include sunlight, water, air, rocks, soil, and minerals.
Factors that could affect the number of organisms in an ecosystem include the availability of food and water, temperature, weather conditions, availability of shelter or habitats, the presence of predators and disease, and human activities such as deforestation or pollution.
Organisms interact in an ecosystem to obtain resources such as food, water, shelter, and mates, and to avoid being eaten by predators or infected by diseases. Some organisms also form mutualistic relationships, where both parties benefit from the interaction.
Different ecosystems can have different organisms and interactions based on the unique features of each ecosystem, such as climate, geography, and available resources.
Understanding feeding relationships in an ecosystem is important because it helps us understand the flow of energy and nutrients through the ecosystem. This knowledge can inform conservation efforts and help us manage and protect ecosystems for the benefit of all living organisms, including humans.
Answer:
1. An ecosystem is a system of interactions between living and nonliving things in a particular environment.
2. Some examples of nonliving things in an ecosystem include sunlight, soil, rocks, air, water, and temperature.
3. Factors that could affect the number of organisms in an ecosystem include availability of resources, predation, competition, and environmental changes.
4. Organisms interact in an ecosystem in order to find food, to find mates, to escape predators, and to compete for resources.
5. No, you would not expect to find the same kinds of interactions between organisms in very different ecosystems due to differences in biotic and abiotic factors.
6. It is important to understand feeding relationships in an ecosystem because understanding these relationships gives us insight into the stability, dynamics, and functioning of the overall ecosystem. It can also provide an understanding of how the ecosystem may respond to environmental changes.

Create a hypothesis that can be tested in an experiment.
Remember, a hypothesis has a specific "if then" wording.It describes what will happen to the dependent variable when changes are made to the independent variable.For example, "If a plant is fertilized (independent variable), then it will grow faster (dependent variable)."
Design and plan an experiment.
Be sure to identify an independent variable, a dependent variable, and any controls.Remember, controls are factors which stay the same.In an experiment designed to test the previously stated hypothesis, one control would be to use the same kind of plant.Write a complete description of your experiment.Include a list of necessary materials.It is a good idea to follow a step-by-step procedure format.Think of everything you need to do, then write it down in the order it must be completed.Your description and procedure should be clear enough that another person could duplicate your experiment exactly.
Answers
Answer: E
Explanation:
Experiment Design:
Independent Variable: Intensity of light (Low, Medium, High)
Dependent Variable: Rate of photosynthesis (measured by oxygen production or CO2 consumption)
Control: Same kind of plant, constant temperature, constant CO2 concentration, constant water availability, and constant duration of light exposure.
Materials:
Three identical potted plants (of the same species)
Light source(s) with adjustable intensity
Light meter (lux meter) to measure light intensity
CO2 gas sensor or oxygen gas sensor
Timer or stopwatch
Water supply
Thermometer
Data recording sheets
Procedure:
Set up the three identical potted plants in a controlled environment with the same temperature and CO2 concentration.
Ensure that all plants receive the same amount of water.
Place the light source(s) at an equal distance from the plants.
Measure and record the initial light intensity using the lux meter.
Adjust the light intensity to low for the first plant, medium for the second plant, and high for the third plant.
Start the timer and expose the plants to light for a specified duration (e.g., 1 hour).
During the exposure period, measure and record the temperature, CO2 concentration (if possible), and light intensity at regular intervals.
After the exposure period, use the CO2 gas sensor or oxygen gas sensor to measure the change in CO2 concentration or oxygen production, respectively, in the surrounding air.
Record the data obtained from the sensors and calculate the rate of photosynthesis for each plant.
Repeat the experiment multiple times to ensure reliability and average the results.
Analyze the data collected and compare the rates of photosynthesis among the three different light intensities.
Draw conclusions based on the analysis and determine whether the hypothesis is supported or rejected.
By following this experimental design, you can test the hypothesis and determine the effect of light intensity on the rate of photosynthesis in plants. Remember to conduct the experiment in a controlled environment and gather sufficient data for accurate analysis.

write a mini-essay about Balanced & Unbalanced Forces
Answers
Answer:
Forces have a magnitude (strength) and a direction. Forces can be represented as arrows with the length of the arrow representing the magnitude of the force and the head of the arrow pointing in the direction of the force. Using such arrows, the resulting force (net force) and direction can be determined.
Forces acting on an object can be balanced or unbalanced.
Balanced forces acting on an object in opposite directions and equal in strength, as shown in the arrows below, do not cause a change in the speed of a moving object.
Objects that are not moving will not start moving if acted on by balanced forces.
For example, in arm wrestling where there is no winner, the force exerted by each person is equal, but they are pushing in opposite directions. The resulting force (net force) is zero. Or, in a tug of war, if there is no movement in the rope, the two teams are exerting equal, but opposite forces that are balanced. Again, the resulting force (net force) is zero. Unbalanced forces are not equal, and they always cause the motion of an object to change the speed and/or direction that it is moving. When two unbalanced forces are exerted in opposite directions, their combined force is equal to the difference between the two forces.
The magnitude and direction of the net force affects the resulting motion
This combined force is exerted in the direction of the larger force
For example, if two students push on opposite sides of a box sitting on the floor, the student on the left pushes with less force (small arrow) on the box than the student on the right side of the box (long arrow).
The resulting action (net force: smaller arrow to the right of the = shows that the box will change its motion in the direction of the greater force as shown below:

Explanation:
This option provides a clear and practical approach to the seed germination investigation. By setting up different conditions for the seeds, such as light vs. dark or wet vs. dry, the students can observe and compare how these conditions affect the germination process. Additionally, potting the same seed in multiple pots allows for a controlled comparison within the experiment.
By manipulating these variables, the students can gather valuable data and observations regarding the influence of light and moisture on seed germination. This approach promotes a hands-on and investigative learning experience, encouraging students to actively engage with the scientific process while documenting the changes that occur over time, such as the emergence of roots and shoots.

Answer:
S - Savannas are typically found in tropical or subtropical regions.
S - Savannas tend to have more trees and shrubs.
S - Savanna's climate is drier than that of a grassland.
G - Grasslands are found in temperature regions.
G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.
G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.
B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.
B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.
B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.

Discuss voluntary and involuntary actions in movement. Include skeletal tissue, cardiac tissue, and smooth tissue in your response.
Answers
Answer:
Muscle tissue is characterized by properties that allow movement. Muscle cells are excitable; they respond to a stimulus. They are contractile, meaning they can shorten and generate a pulling force. When attached between two movable objects, in other words, bones, contractions of the muscles cause the bones to move. Some muscle movement is voluntary, which means it is under conscious control. For example, a person decides to open a book and read a chapter on anatomy. Other movements are involuntary, meaning they are not under conscious control, such as the contraction of your pupil in bright light. Muscle tissue is classified into three types according to structure and function: skeletal, cardiac, and smooth.
Skeletal muscle is a voluntary muscle, whereas cardiac tissue and smooth muscle are involuntary muscles.
What is muscle tissue?Muscle tissue is one fundamental type of tissue that is able to contract and thus produce different types of movements.
Muscle tissues can ve subdivided into three types, which include skeletal muscle, cardiac tissue and smooth muscle.Cardiac tissue is present in the heart, whereas smooth muscle is present in the digestive system.In conclusion, skeletal muscle is a voluntary muscle, whereas cardiac tissue and smooth muscle are involuntary muscles.
