Spermatogenesis is the process of formation of haploid sperms for diploid stem cell
Oogenesis is the process of formation of ovum
Answer:
Collect DNA from individuals who are lactase persistent and are from the global hot spot populations. Then look for genetic differences correlated with lactase persistence; the first place to look would be in and around the lactase gene. Compare the genetic differences to see if they are the same or different.
Explanation:
Answer:yes
Explanation:
Ion pumps are assemblies of integral membrane proteins, like ion channels, that modulate ion transport into and out of a cell or organelle, leading to generation of electrical signals. Ion pumps, however, work against their concentration gradient, so require energy input, but the energy can also be derived from the concentration gradient of another ion.
Take the Galapagos birds as an example...
Birds develop different traits for different areas and climates.
Answer:1)Hexokinase
2)Phosphofructokinase (PFK)
3)Pyruvate kinase
Explanation:
The most important means of releasing energy from the glucose molecule is initiated by glycolysis.Glycolysis means splitting of the glucose molecule to form two molecules of pyruvic acid.The end products of glycolysis are then oxidized to provide energy.
Three reactions of glycolysis are highly exogernic,resulting in highly negative free energy changes that are irreversible and must be bypassed by different enzymes.These enzymes are hexokinase, Phosphofructokinase(PFK) and pyruvate kinase.
When the body's stores of carbohydrates decrease below normal,moderate quantities of glucose can be formed from amino acids and the glycerol portion of fat.This process is called gluconeogenesis. It is an important pathway that allows the body to store needed energy for the brain in the form if glucose.
