Think about the plants and animals of land habitats which might you write an ad for and why

Answers

I would choose any endangered animal, such as a panda, the western lowland gorilla, or the Asian elephant. Endangered or rare plants work too.

And then just find information on why the animal you chose went endangered, and what kind of habitat it lived.

Then you can write that you chose the animal because it’s endangered, and has a simple habitat (if it has a simple habitat).

I would choose a Polar Bear because they’re unique and live in the Arctic. They’re endangered and are my favorite animal. #savethepolarbears <33

Look at the diagram of the rock cycle below.

A.

B.

C.
crystallization
D.
mineral integration

Answers

answer B.

it’s melting

From the diagram of the rock cycle the missing part is ( B ) ; Melting

Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.

Magma is released to the earth surfaces during volcanoes therefore the missing term in the rock cycle is melting

Hence we can conclude that from the diagram of the rock cycle the missing part is Melting.

how do creationists and evolutionists differ in their views of natural selection?

Answers

Answer: creationists believe in higher power to create things as is and evolutionists believe we originate from a common past and constantly change

Explanation: Creationists believe the belief that the universe and living organisms originate from specific acts of divine creation, as in the biblical account, rather than by natural processes such as evolution.

The theory of evolution is based on the idea that all species are related and gradually change over time. Evolution relies on there being genetic variation in a population which affects the physical characteristics (phenotype) of an organism.

Answer:

Creationists believe that natural selection is a God ordained process. Evolutionists believe that natural selection is a scientific process.

Internal and External Structures

You are now going to construct an argument that plants have internal and external structures that support growth and reproduction.

Choose the internal and external structures you want to gather evidence and create a statement about.

subject: sciences

Answers

Explanation:

Some structures are internal, like the lungs, brain, or heart. Other structures are external, like skin, eyes, and claws. Some structures are unique, like the long neck of a giraffe. Other structures are more common, like a heartStructure and Function: Plants and animals have both internal and external structures that serve various functions in growth, survival, behavior, and reproduction.

Plants have internal and external structures just like us humans do. While humans internally have lungs, a heart, and intestines Plants have that to. Plants have different fibers that allow the it to move water, make food, do photosynthesis, etc. So for this you could pick a couple different plant fibers such as the sclerenchyma fiber and the parenchyma fiber. The sclerenchyma fiber allows the plant to come out of the ground. This fiber is essentially its bones. The parenchyma fiber allows photosynthesis to occur. It moves water creates food etc.

Different organisms have a different amounts of chromosomes. Therefore, it is false.

What are chromosomes?

The thread-like chromosomes that convey the genomic information from cell to cell are formed of protein and a single DNA molecule. Chromosomes are found in the nucleus of cells in both plants and animals, including humans.

Each cell's nucleus contains chromosomes, which are structures that resemble threads and contain the DNA molecule. Each chromosome is constructed from DNA that has been tightly wound around proteins called histones numerous times to support its structure.

Not all organisms have the same amount of chromosomes, such as drosophila has 4 chromosomes, humans have 46, a dog has 78 chromosomes and an onion has 16 chromosomes. Therefore, it is false.

A _______________ identifies a pathogen by recognizing molecules on the surface of the microbe called _______________. These cells signal _______________ to produce chemicals called ______________ that bind to the antigen, marking the pathogen for destruction. Other immune cells attack the targeted pathogen by detecting its ______________. plz help due today will mark brainly

Answers

Answer:

An immune system identifies a pathogen by recognizing molecules on the surface of the microbe called epithelials. These cells send signals to the cytoplasm to produce chemicals called lipopolysaccharides that bind to the antigen and mark the pathogen for destruction. Other immune cells attack the target pathogen by detecting its immune system.

Explanation:

Innate cell recognition systems are based on surface or intracellular proteins of epithelial cells, neutrophils, macrophages, and dendritic cells and on soluble cytoplasmic receptors. All these receptors are generally called PRRs (Pattern Recognition Receptors) and bind to PAMPs (Pathogen-associated Molecular Patterns) molecules expressed only by the pathogen (bacterial lipopolysaccharides, carbohydrates and lipoproteins, peptidoglycans, RNA, DNA, etc.) thus as for the commensal flora.

Observation
Use your senses to make an observation about your environment.
Questions
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:

If the intensity of light (independent variable) is increased, then the rate of photosynthesis (dependent variable) in a plant will also increase.

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.
