Scientists compare DNA from living organisms to identify similarities between species
Answer: Option D
<u>Explanation:</u>
The DNA content of any organism codes for its behavior and other activities, the nucleic acid is the only encryption that takes the internal code of the parents to the off springs, hence a comparison in the evolution can be done only through testing the DNA content.
The information in the DNA also tells us the evolution of species along with their relationship with each other. Thus helps in the construction of the phylogenetic tree.
Answer:
Vasopressin
Explanation:
Vasopressin is an anti-diuretic hormone. Its main function is to control the osmolality and volume of body fluids, helping the body to lose fluids. The secretory neurons are activated as a result of increased osmotic pressure or reduced blood pressure, which is also reduced by this hormone. The release of this hormone has a potent vasoconstrictor effect, causing water retention to increase, acting as an antidiuretic hormone. The increased permeability of the collecting tubules and the thick ascending branches of the Henle loop, resulting from the exposure of aquaporins to the apical membrane, enables the diffusion of water found in the tubule cells to the medullary region of the kidney.
Given what we know, after you’ve removed a loopful of broth culture from the culture tube you should immediately apply a flame to the open end of the test tube.
<h3>Why would this be the next step?</h3>
Once you have removed the loopful of broth culture from the tube, you should apply a flame to the end of the tube, this is of vital importance. The reason for this is to deny any other contaminants from entering or exiting the culture sample.
Therefore, we can confirm that after you’ve removed a loopful of broth culture from the culture tube you should immediately apply a flame to the open end of the test tube.

B
Plant's cuticle is an adaptation on land that prevents the evaporation of water from the plant.
Explanation:
The cuticle is made of lipid polymers impregnated with wax. A thick cuticle covers the epidermis of the leaves and prevents of some plants to prevent the loss of water from the leaves and plants via evaporation. This is especially a significant adaptation to desert plants that need to conserve water because they receive very little annual rainfall in their environment.
