White blood cells are made in the bone marrow. They are stored in your blood and lymph tissues. They help the body fight infection and other diseases.
<span>Disaccharides need to be broken down into their component subunits (monosaccharides) before their absorption. The reaction that breaks them up is hydrolysis and it is done by enzymes- <span>glucosidases. Glucosidases are located on the brush border of the small intestine, attached to the surface of the epithelial cells. After the catalyzation of these disaccharides, the epithelial cells take up the monosaccharides and transport them inside using ATP energy. From there they are transported into the bloodstream.</span></span>
Answer:
A
Explanation:
The only way for a cell to use energy stored within a molecule is in this example would be to break the bond between 1 and two because it would be impossible for energy to get to 3, 4, 5.
Molecular clocks B. TAKE ADVANTAGE OF THE FACT THAT ALL MUTATIONS HAPPEN AT A STEADY RATE.
The molecular clock is a technique used involving the mutation rate of biomolecules to deduce when in prehistoric times have two or more lifeforms diverged.
Answer:
A) birds have a large opening where the beak should be.
Explanation:
