Blood is made up of red and white blood cells, platelets and plasma. The plasma consists of water (mostly) and dissolved nutrients. When blood is exposed to air, the blood will clot, due to aggravation of the platelets. Then you get a  forming scab that will help heal the part that the blood is being exposed from.

Why is feedback inhibition important in metabolic pathways?
GrogVix [38]

Answer:

To balance the production of certain products.

Explanation:

Feedback inhibition is when byproduct from metabolic reactions in cells accumulates and is in excess. The product goes and inhibits the enzyme that is responsible for speeding its chemical reaction, balancing the amount of product needed, with the amount already produced.

Therefore feedback inhibition is important in metabolic pathways because it balances the production of amino acids and nucleotides. It is there to ensure that the exact amount needed is produced.

two pea plant with yellow peas are crossed most of their offspring have yellow peas but about 25% of the offspring have green pe
Mrac [35]

Answer:

Both parents have the genes for yellow peas and green peas

Explanation:

If a plant has inherited one yellow peas gene and one green peas gene, the plant will produce yellow peas because (as you mentioned) yellow peas are dominant. that means the parents are heterozygous (Cc). If both parents have the gene versions Cc, then there is a 25% chance the offspring would get the gene version cc, coding for green peas.
