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.

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.
Therefore, 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.

Describe how the state of matter will affect the usefulness of materials used in a stepping stone
Answer: The states of matter can be solid, liquid, and gas.
Explanation:
The change in the state of matter can change the utility of the materials. Like, water in the liquid state when changed into solid ice can be used as ice cube and in the gaseous vapors can be used for steaming food items.
The stepping stone is a stone which is used for roadside pavements. It is used for walking. It can be prepared using liquid mixture of cement and concrete into a mold and it is converted into solid mass on drying.
Explain how reproduction take place in mustard plant
Answer:
It is a winter plant that inseminates very quickly at high temperatures.
Explanation:
Mustard is an annual plant. Its root is spindle-shaped, well developed, and the stem is erect, branched, small, 50-90 cm high. The lower leaves are larger with a stalk, and the upper ones are smaller sitting. Mustard blooms in late May and early June.
The fruit ripens in the second half of July. The flowers are yellow, fragrant, very honey-bearing with a lot of pollen powder, and are collected in clustered inflorescences. They are pollinated by insects.
The fruit of the mustard is a cylindrical shell, hairy, 2-5 cm long, and about 5 mm wide. The growing season of mustard is 110-130 days.
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.

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.

We wish to test if a certain vaccine developed for a
disease is effective or not. What is the best way to do
this?
A
Vaccinate 100 animals
and expose all 100 to the
disease.
B
Vaccinate 100 animals
and expose 50 of them to
the disease.
C
Vaccinate 50 animals, do
not vaccinate 50 other
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. independent variable
B. extraneous variable
C. control group
D. controlled variable
E. dependent variable
Answer: Control Group
Explanation:
A group in which everything is the same as the test group except that the independent variable stays the same is a control group that is in option C, as the control groups never change.
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.
Hence, a group in which everything is the same as the test group except that the independent variable stays the same is a control group that is in option C, as the control groups never change.
