It is green only 2% have green eyes
An increase in temperature will minimize the amount of dissolved oxygen in the water and increase the metabolic rate of the goldfish, thus causing the goldfish's respiration rate to increase (“Hot waters make it hard for fish to breathe.
pls mark me as brainliest.......
D.cyanobacteria hop that this helps some
Answer:
The correct answer is: A. active transport requires energy.
Explanation:
- Active transport can be defined as the physiological process by which molecules are enforced to migrate from a region where their concentration is low to a region where their concentration is high across a semi-permeable membrane. This occurs by the expenditure of energy. This type of movement is usually carried out by the integral membrane transport proteins or carrier proteins those remain interspersed across the plasma membrane.
- Passive transport can be defined as the physiological process in which no energy expenditure is required. This is because in this form of transport, molecules move from a region where their concentration is high to a region where their concentration is low, that is, down the gradient of their concentration, across a semi-permeable membrane. This type of movement can be mediated by simple diffusion or with the help of membrane transport proteins.
Ans.
Errors that occur during DNA replication lead to mutations, which represent permanent, heritable changes in genetic material. These errors can pass from parent cell to daughter cells and affect many generations of cells.
On the other hands, errors that occur during protein synthesis lead to formation of defected or non-functional protein. These errors cannot pass from one cell to another and affect only one cell, which requires that protein for its proper functioning.
Thus, 'it is more important to check errors during DNA replication that errors during protein synthesis.'
