Answer:nucleus
Explanation: In eukaryotes, however, genetic material is housed in the nucleus and tightly packaged into linear chromosomes. Chromosomes are made up of a DNA-protein complex called chromatin that is organized into subunits called nucleosomes.
Answer:
e. secretion, absorption and chemical protection
Explanation:
Epithelial tissues is responsible for the protection of the skin, absorption of nutrients during digestion and secretion of waste materials. These tissues form covering to all body surfaces. They also perform a variety of other functions such as excretion of waste substances, filtration of air from dirt and particles and clean the air that is inhaled, diffusion, and sensory reception.
Answer:
Prophase
Explanation:
parent chromosomes are condensed into an x shape
Answer:
Phosphofructokinase will be activated
Explanation:
Phosphofructokinase (PFK-1) is an enzyme of glycolysis that catalyzes the phosphorylation of fructose 6-phosphate to fructose 1,6-bisphosphate. The enzyme uses ATP as a phosphate group donor for this phosphorylation. It is a regulatory enzyme and the reaction catalyzed by it is irreversible. The activity of PFK-1 is increased whenever the cell’s ATP supply is depleted or when the ATP breakdown products, ADP and AMP, are in excess.
Answer:
It is possible for two of the same species to have differences in their DNA.
