Answer:
An arctic fox changes its fur color to blend in with its surroundings
Explanation:
This is a defense mechanism because when it blends into its surroundings it can hide from its predators and help defend itself
The example most accurately describes a defense mechanism used by an animal is a baby goose recognizes its mother and follows her movements. Thus, option B is correct.
What is arctic fox?An arctic fox changes its fur color to blend in with its surroundings and this is a defense mechanism because when it blends into its surroundings it can hide from its predators and help defend itself.The brown color camouflages the brown fox in the forest.
Adaptation is changing of character of an organism for a short time to survive in severe environmental conditions.The brown color camouflages the arctic fox when the snow melts during the summer. The white color camouflages the arctic fox during the winter.
There are various factors which control the regulation of a gene. Temperature can be a regulatory factor for certain genes. Probably, during the warm temperatures, the proteins regulating the fur colour to become reddish brown become activate these genes. As a result, the fur becomes evident.
Therefore, The example most accurately describes a defense mechanism used by an animal is a baby goose recognizes its mother and follows her movements. Thus, option B is correct.

Pls help like asap, i will give brainliest!!!
Answer:
Amino Acids im pretty sure
Nitrogen is an essential element required by all the organisms present on the Earth. Nitrogen is found in all amino acids and nucleotides. The nitrogen from animal waste can be stored as nitrate, ammonia, or nitrites.
Nitrogen is an essential compound, which makes up the amino acid and many other biomolecules.
The nitrogen is released into the atmosphere through animal manures or waste. Animal manure serves as the source of nitrogen for plants and other organisms.
The nitrogen released by the aquatic organisms is the primary source of circulation of nitrogen in the marine environment.
The nitrogen when dissolved in the water exists as nitrates, ammonia, or nitrites.
Therefore, nitrogen exists as nitrates and nitrites when stored in water bodies.

Describe how geologists use index fossils. List the characteristics that make an index fossil.
A index fossil can be recognized easily and abundant, and have a wide geographic distribution and a short range through time. Index fossils are the basis for defining boundaries in the geologic time scale and for the correlation of strata.This all are the benefits of maintaining index fossil.
What is fossil?If scientists excavate two fossils at the grand canyon, one of which found at a much deeper rock layer than other, so we assume that the fossil has been found in the deeper layer has been older and fossil which found in upper layer are newer.
A fossil fuel has been hydrogen- containing material found naturally in the earth's crust from the remain of the dead plants and animals that is extracted and burned as a fuel.
Fossil are the natural source of energy, it has been made from decomposition of the plants and animals. Fossil fuels are said to be found in the earth's crust and it contains carbon and hydrogen which could gives energy by burning.

Scientists first collect ice cores from deep under the arctic and antarctic ice shelves. Next, they measure the concentrations of gasses trapped in the ice to determine how long ago the ice was formed and what the composition of the atmosphere was like at the time. These ice cores are like little time capsules showing what Earth’s atmosphere and climate were like in the past.

How is carbon released from the soil?
Describe three scenarios/conditions that would inhibit the carbon cycle from the second animation.
Describe three scenarios/conditions that would promote the carbon cycle from the second animation.
What role do decomposer play in the carbon cycle?
Answer:
1.Living things in the ocean move carbon from the atmosphere into surface waters then down into the deeper ocean and eventually into rocks. This action of organisms moving carbon in one direction is often called a biological pump.
Carbon gets incorporated into marine organisms as organic
Molecules that contain carbon and that have a biological origin.
2.Through the process of photosynthesis carbon dioxide oxide is pulled from the air to produce food made from carbon for plant growth. Carbon moves from plant to animals. Through food chain , the carbon that is in plant moves to the animal that eat them. Animals that eat other animals get the carbon from their food too.
3.soil naturally absorbs carbon from the atmosphere through the process known as sequestration which not only reduce harmful gases but also creates more fertile soil.
4.Soils play a key role in the carbon cycle by soaking up carbon from dead plant matter. Plants absorb CO2 from the atmosphere through photosynthesis, and pass carbon to the ground when dead roots and leaves decompose.

What is the significance of the control group in the experiment?A control group is a set up in a scientific experiment that serves as a baseline for comparison with other unknown samples, and after testing the control group with the results of the treatment group, researchers can determine the effect of the independent variable. The control group is the sample whose value is known to the scientists.

animals, and expose all
100 to the disease.
D
Vaccinate 50 animals, do
not vaccinate 50 other
animals, and expose the
vaccinated animals to the
disease.
Answer:
The best way to test the effectiveness of a vaccine against a disease is vaccinate 50 animals, do not vaccinate 50 other animals, and expose all 100 to the disease (option C).
Explanation:
When testing a vaccine for effectiveness, the option is to administer the vaccine to half of the population exposed to a disease, since effectiveness should measure the performance of the vaccine within a community.
If there are 100 animals exposed to a disease, the fact that the 50 vaccinated animals do not get sick is an excellent test of how the vaccine works and what its effectiveness is.
The other 50 animals, not vaccinated, would act as a control group exposed to the same disease and sharing a certain space.
The other options are not correct because:
A. Vaccinating the 100 exposed animals does not provide an unvaccinated control group to compare the effects of the vaccine.
B. Vaccinating all 100 animals and exposing only 50 to the disease does not make sense, since it would not be possible to measure effectiveness in vaccinated animals that are not exposed.
D. Vaccinating 50 animals and not vaccinating the other 50 to expose only the vaccinated animals to the disease does not make sense since the conditions of the test group and the control group should be the same.

A student was setting up beakers that contained different solutions in order to conduct a laboratory investigation, but the next day he could not tell which beaker contained the starch and water mixture. In order to find out which beaker contained starch, he took small sample from each of the beaker and conducted a test for starch on each of them. Describe the test for starch that the student should use and the result that would indicate the presence of starch
Answer:
See the answer below
Explanation:
In order to test for starch and distinguish the beaker containing a mixture of startch and water, a small quantity of the solutions in each beaker should be taken and and drops of iodine added. The solution that gives off a blue/black color from the yellow/brown color of the iodine would be the starch water solution.
Generally, starch turns iodine solution to blue/black from the usual yellow/brown color of the substance.
