Answer:
c
Explanation:
the environment is changing from ocean to dry land
According to the research, the correct option is A, population genetics is the study of how allele frequencies in a population change over time.
<h3>What is population genetics?</h3>
It studies the origin, amount and distribution of genetic variability present in populations.
It explains the variation between individuals, as well as the dynamics of alleles and genotypes within and between populations.
Therefore, we can conclude that according to the research, the correct option is A, population genetics is the study of how allele frequencies in a population change over time.

Answer:
b. muscle
Explanation:
The Sponges usually known as Porifera (pore bearers) are aquatic filter feeders. The sponges consist of structural materials (spongin, spicules) which are usually made of calcium carbonate and/or silica. These structures forms their skeletal materials giving their body a thin sheet of cells over a frame (skeleton). As invetebrate and at the unicellular level of organization, Sponges lack muscle.
The correct answer is option a, that is, Vitamin K.
Vitamin K is primarily produced by the bacteria in the large intestine. The dietary sources include the green photosynthetic parts of the plants. The vitamin plays an essential role in the development of many blood-clotting factors in the liver, and their deficit can result in bleeding disorders.
There are two sources of vitamin K; this includes phylloquinone or vitamin K1, which is mainly found in green leafy vegetables and menaquinone or vitamin K2 that is produced by some kinds of intestinal bacteria.
Answer:
A: Oil
Explanation:
Chemo synthesis is the biological conversion of one or more carbon-containing molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic compounds (e.g., hydrogen gas, hydrogen sulfide) or methane as a source of energy.
Bacteria living on the sea floor or within animals use energy stored in the chemical bonds of hydrogen sulfide and methane to make glucose from water and carbon dioxide.
Chemo synthetic bacteria are organisms that use inorganic molecules as a source of energy and convert them into organic substances. Chemo synthetic bacteria, unlike plants, obtain their energy from the oxidation.
So Oil is not a possible source of energy for Chemo synthesis.
