Snakes can live up to 9 years. They slither up to 18 mph. Snakes are reptiles that are elongated, limbless, and carnivorous. Another interesting thing about snakes is that they don’t have eyelids. The last fact is that snakes can open there mouths up to 150 degrees so they can swallow there prey.
B.
Genetic drift is the change in the frequency of an existing gene variant in a population due to random sampling of organisms.
Answer: A) sporopollenins
Explanation: Sporopollenin is one of the most chemically inert biological polymers. They contain mainly long chain fatty acids, phenylpropanoids, phenolics and traces of carotenoids. They make up the outer wall of pollen grains, spores and many microorganisms.
Answer:
FALSE
Explanation:
Ionization energy is the minimum amount of energy required to discharge an electron from its orbital shell from an atom in ground electronic state. The closer the electron, that is to be discharged, is to the nucleus of the atom, the harder to remove it hence has high ionization energy. In addition, if the nucleus of the atoms has a higher mass and the electron is even closer, the higher the ionization energy.
An active transport is the process by which a substance is transported or transferred from one area to another using a chemical energy in the course.
<span>As oppose to passive transport, active transport’s key to its description uses energy to be able to transfer the said substance. This is important in a lot of aspects such as providing the needed elements or compounds in cellular activity.<span>

<span>Diffusion occurs because of the movement of molecules from the region of higher concentration to the region of lower concentration.
Omosis is the movement of water.
