MIGHT GIVE BRAINLIEST Compare a paramecium with a giraffe. How are their cells alike? How are they different? Write
your answer in complete sentences. be original
Answers
Answer:
A paramecium is similar to a giraffe in one defining way. Both a giraffe and paramecium have eukaryotic cells. One way in which the two are different is that the paramecium feeds on decaying organisms, whilst a giraffe eats leaves. Another is that paramecium primarily live in fresh water, while a giraffe dwells on land.
A paramecium and a giraffe are two very different organisms. A paramecium is a single-celled organism, while a giraffe is a large, multicellular mammal. Despite their many differences, both a paramecium and a giraffe have cells. However, the cells of a paramecium and a giraffe are quite different from each other in terms of size, shape, and function.
One of the most significant differences between the cells of a paramecium and a giraffe is their size. The cells of a paramecium are very small, measuring only a few micrometers in diameter. In contrast, the cells of a giraffe are much larger and more varied in size, depending on their function within the body. For example, giraffe nerve cells are much larger than giraffe red blood cells.
Another important difference between the cells of a paramecium and a giraffe is their shape. The cells of a paramecium are typically elongated and oval-shaped, with a pointed end at one end and a rounded end at the other. In contrast, the cells of a giraffe are much more varied in shape, depending on their location and function within the body. For example, giraffe muscle cells are long and cylindrical, while giraffe nerve cells are elongated and have many branching extensions.
Despite their many differences, the cells of a paramecium and a giraffe do have some similarities. For example, both types of cells have a cell membrane that surrounds the cell and controls the movement of materials in and out of the cell. Both types of cells also have a cytoskeleton, which provides support and structure to the cell. Additionally, both types of cells have a nucleus, which contains the cell's genetic material.
Overall, while the cells of a paramecium and a giraffe have some similarities, they are also very different from each other in terms of size, shape, and function. The small, simple cells of a paramecium are adapted for life in a single-celled organism, while the larger, more complex cells of a giraffe are adapted for life in a multicellular mammal.

Answers
Ingestion
And suffocation
Answer:
Negative physical impact on marine life, chemical impact on the water, and transport of native species.
Explanation:
Negative physical impact on marine life:
Plastic can be dangerous to creatures living in the ocean. Marine animals can fatally swallow plastic, become entangled in it, and even become physically impaired for the rest of their life.
Chemical impact on the water:
Plastics carry chemicals such as PCBs and DDT that can invade the water and cause harm to marine ecosystems.
Transport of native species:
Plastic can carry organisms from one part of the ocean to a relatively remote area. By introducing new organisms to an ecosystem, the flow can be disrupted and result in major consequences.

How do fossil fuels play a role in the carbon cycle?(1 point) Fossil fuels require a lot of carbon to burn, which releases carbon into the atmosphere. Fossil fuels require a lot of carbon to burn, which releases carbon into the atmosphere. Fossil fuels are rich in carbon, and burning them returns carbon to the soil. Fossil fuels are rich in carbon, and burning them returns carbon to the soil. Fossil fuels require a lot of carbon to burn, which takes carbon out of the atmosphere. Fossil fuels require a lot of carbon to burn, which takes carbon out of the atmosphere. Fossil fuels are rich in carbon, and burning them releases carbon into the atmosphere. Fossil fuels are rich in carbon, and burning them releases carbon into the atmosphere.
Answers
Answer:
Fossil fuels are rich in carbon, and burning them releases carbon into the atmosphere.
Explanation:
The amount of carbon in the form of carbon dioxide in the atmosphere is about 0.03% by volume. This value is kept fairly constant by a natural process known as the CARBON CYCLE. This involves carbon dioxide being continually removed from the atmosphere by plants in photosynthesis, rain water as weak acids while in order to maintain this balance, carbon dioxide is at the same time returned to the atmosphere by:
→ burning of carbon containing substances (fossil fuel)
→ respiration of plants and animals and
→Decomposition of organic substances.
Hence, Fossil fuels which are rich in carbon content releases carbon into the atmosphere when burnt.
Answer:
Fossil fuels are rich in carbon, and burning them releases carbon into the atmosphere.
Explanation:
Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels.

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.

Fix nitrogen is from soil, plants and animals consuming it which causes it to recycle, nitrogen is cycled through: plants, soil, animals, bacteria and water and the atmosphere. I hope this helped!
Explanation:
Bacteria breaking down nitrogen compounds releases free nitrogen.Explanation:The nitrogen cycle is a process in which nitrogen is recycled through different components of the environment. Bacteria play an important role in this cycle by breaking down nitrogen compounds found in plants, animals, and soil. When bacteria break down these compounds, they release free nitrogen into the environment. This free nitrogen can then be used by other organisms like plants to create proteins and other essential molecules. So, bacteria breaking down nitrogen compounds is an important step in the nitrogen cycle.

Giant anteaters live in Central and South America. As their name suggests, they eat ants and termites. First, an anteater tears open insect nests with its long claws. Then, it extends its extremely long, sticky tongue into the nest to catch its prey. One anteater eats 35,000 ants and termites in a day.
Aardvarks have a lifestyle similar to anteaters but live in Africa. Like anteaters, aardvarks dig up ant and termite nests. They also extract insects with a long, sticky tongue. The two mammals are so similar that at first taxonomists thought they were closely related. However, further study showed that aardvarks are in the order Tubulidentata, while the anteaters are in the order Pilosa.
