2nd one is Eukaryota domain
The correct answer is stabilising selection. This is selection that favours an average trait value. It is thought that this sort of selection is very common as traits among most animals do not appear to change drastically over time. Stabilising selection selects against the extreme traits, and leads to a decrease in genetic diversity by favouring the average phenotypes.
A cell that consists of 3 types the cell membrane,the nucleus,and between the two,the cytoplasm within the cytoplasm lie intricate arrangements of fine fibers.
Answer:
Humans maintain a body temperature of 37oC; .
If the temperature is above or below 37oC, the hypothalamus receives information from thermo receptors in our skin and sends electrical impulses, along nerves, to the parts of the body which have the function of regulating our body temperature
Answer;
Carbon
Explanation;
-The large diversity of shapes of biological molecules is possible because of the extensive presence of carbon in the molecules.
-The major classes of biological molecules that are important for all living things are carbohydrates, lipids, proteins, and nucleic acids. These molecules differ in structure and function, in part, because of different functional groups.
All organic molecules contain carbon atoms. Biological macromolecules are organic, meaning that they contain carbon. In addition, they may contain hydrogen, oxygen, nitrogen, phosphorus, sulfur, and additional minor elements.
-Carbon qualifies as the foundation element for molecules in living things. It is the bonding properties of carbon atoms that are responsible for its important role.
