Something that requires a lot of energy, such as active transport, as more mitochondria means more respiration.
Answer:
You would expect to find glutamic acid on the fringes of the three-dimensional protein structure while valine would be found mostly inside the protein structure.
This is because hydrophilic molecules are ‘water-loving’ because they carry a charge and can, therefore, interact ‘positively’ with water by forming hydrogen bonds with the polar water molecules. Hydrophobic molecules on the other hand are water-hating. They carry no charge hence have no way of ‘positively’ interacting with the polar water molecules.
Remember the structure of the cell membrane too? The negatively-charged phosphate ends of the phospholipid bi-layer sandwich the non-polar fatty acid chains because they don't ‘like’ interacting with water. This applies to the same principle.

Answer:
A mutation may be bad and good depending on the particular environmental conditions
Explanation:
For example, the falciform anemia is a hereditary disease caused by a mutation where the ability to transport oxygen of red blood cells is reduced; however, this genetic disorder is widespread in some African populations because it is a condition that confers resistance to falciparum malaria. In consequence, falciform anemia is a detrimental mutation that may also be beneficial in endemic malaria regions.
Moreover, it is important to note that the higher proportion of non-synonymous substitutions are not subject to selection (only a minor percentage are positively selected) because they are generally localized within non-coding regions, thereby having neutral status.
Clouds form when moist, warm rising air cools and expands in the atmosphere. The water vapor in the air condenses to form tiny water droplets which are the basis of clouds.
Without agriculture my life would be different as I would not have acsess to all these fresh fruot and vegetables we have today. Our diets would have to adapt to more unnatural food, and our bodies would not be as healthy as they are now.
