Comparative embryology is one of the main lines of evidence in support of evolution. In comparative embryology, the anatomy of embryos from different species are compared through the embryos development. Similarities between different species indicate that we all came from a common ancestor.

Answer;
Cell membrane
A cell membrane acts as a boundary that separates things that are inside the system from those that are outside the system.
Explanation;
It is a thin semipermeable structure that surrounds the cytoplasm of a cell.
The membrane functions to protect the integrity of the internal environment of the cell by allowing selective movements of materials in and out of the cell.
The membrane consists of a phospholipid bilayer with proteins embedded in it.

The correct answer will be option-A
Explanation:
The citric acid cycle is the cyclic chain of reactions taking place as a phase of the cellular respiration as it gets halted in the absence of oxygen.
The citric acid cycle converts the obtained acetyl-CoA to a usable form of energy in the form of ATP, NADH and FADH₂.
The citric acid cycle forms intermediates which are utilised by the organisms to synthesise the various biomolecules like amino acids, purines and pyrimidines.
The intermediates like alpha-ketoglutarate forms arginine, proline and glutamine whereas oxaloacetate forms asparagine and aspartate.
If bacteria do not receive the amino acids then they will synthesise the amino acids using intermediates of the citric acid cycle.
Thus, option-A is the correct answer.
Like a lot of lizards, leopard geckos can drop their tails. They do this to distract the predator that might be trying to eat them. Their tails keep moving for a short duration of time after it detaches. It is a defensive mechanism that distracts the predator long enough so they can run into a hide.
