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.

Lion vs elephant digestion lab
Answer:
In lions, digestion takes place in the stomach while in elephant, digestion takes place in cecum.
Explanation:
Lion eats meat which needs a powerful digestion of strong juices which helps in the breakdown of food. There are four compartments of the stomach of lion that are rumen, reticulum, omasum, and abomasum. These chambers have microorganisms which helps in the breakdown of food materials while in the elephant, the stomach primarily functions in the storage of food and digestion takes place in the cecum that is connected to the large intestine.
nitrogen fixation
a) is the process where nitrogen is converted to a usable form
b) is accomplished by plants when they break down soil.
c) occurs as a result of photosynthesis
d) none of the above
Answer:
A. is the process where nitrogen is converted to a usable form
Explanation:
Fixation converts nitrogen in the atmosphere into forms that plants can absorb through their root systems. A small amount of nitrogen can be fixed when lightning provides the energy needed for N2 to react with oxygen, producing nitrogen oxide, NO, and nitrogen dioxide, NO2

Which is the advantage of water's heat capacity?
Answer:
it protects aquatic life from changes in air temperature
Explanation:
Answer:

What is the role of light and chlorophyll in photosynthesis?
Explanation:
During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
Chlorophyll's job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar.
In photosynthesis, role of light is to convert water and carbon dioxide to organic products and chlorophyll helps in absorbing light energy from the sun.
What is photosynthesis?It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy through the process of cellular respiration.
Some of the energy which is converted is stored in molecules of carbohydrates like sugar and starches which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.
The process begins with proteins absorbing light energy which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.

How did Claire’s digestion reaction rates tell you that the problem was in her small intestine, and not her stomach?
Absorption of the nutrients will not happen in her small intestine.
Claire’s digestion reaction rates tell you that the problem was in her small intestine, and not her stomach because the intestine is responsible for the absorption of most of the nutrients produced from eating and drinking of food substances.
If the absorption of the nutrients will not happen by the intestine, the whole homeostasis or equilibrium of the body disturbs and no growth of the cell occurs so we can conclude that absorption of the nutrients will not happen in her small intestine.
