The correct answer of the given question above would be the third option: THE EVOLUTION OF POPULATIONS OVER TIME. What is represented by the base of a phylogenic tree is the evolution of populations over time. It is also known as the evolutionary tree. This tree shows the evolutionary relationships among species.
Answer:
D. Enzymes only break down large molecules.
Explanation:
Enzymes are the substances which helps in the broken down of large food molecules into small molecules. It is because our body is not able to absorb large food molecules, these large molecules are broken down into small molecules with the help of enzymes. Carbohydrate is broken down into glucose by amylase and protein is broken down into amino acids by protease. Enzyme is non-living in nature and used as a catalyst in order to speed up the chemical reaction.
Nephrons
Nephrons are the basic structural
and functional units of the kidneys. Each
of the kidneys contains over a million nephrons. Nephrons function by filtering
blood and then removing needed substances from the filtrate before eliminating
the remaining fluid that contains water, metabolic waste, and toxins.as urine. This process occurs through three stages which
are ultrafiltration, selective reabsorption and osmoregulation.
The right answer is compression.
There are basically two types of constraints that deform rocks: compression and tension constraints. In compression, forces converge; they can be coaxial or not.
The deformation of a card set under compression constraints illustrates the difference: In the case of a coaxial compression constraint, the cards will be arched. If the stresses are not coaxial, shear will develop; the card game is deformed by sliding the cards on top of each other:
