4 0

Answer: Like with fingerprints, no two people have the same brain anatomy, a study has shown. This uniqueness is the result of a combination of genetic factors and individual life experiences.

Explanation: An example is the heart's circulatory system, where the vessel supplying blood to the posterior part, known as posterior descendant artery, stems from the right coronary artery in 80-85% of the cases, and from the left coronary artery in the remaining 15-20%. This is known as either right of left dominance

Answer:

Explanation:

This is because, during lytic cycle,

During the lytic cycle, genome willing f the virus always undergo replication and transcription and the enzymes then degraded the bacteria chromosomes which has been coded by the viral genome to produce deoxyribonucleotides that acts as monomers to in order to produce more viral DNA so that virus will be replicated the more.

The virus find it's way into the the bacteria, then take over the whole macromolecular production and degrade components that are in existence in bacteria so as to get new materials to replicate alot of copies of itself.

What is substrate-level phosphorylation?
Lunna [17]

Answer:

D --  ATP synthesis when the phosphate donor is a substrate with high phosphoryl transfer potential

Explanation:

Substrate- level phosphorylation is the synthesis of ATP from ADP by the transfer of phosphoryl group from a substrate with high phosphoryl group potential to the ADP molecule.

In substrate-level phosphorylation, the donor is a phosphorylated intermediate molecule with a high phosphate transfer potential and it is a way through which phosphate in introduced into a molecule, the other two ways are oxidative phosphorylation and photophosphorylation. In substrate-level phosphorylation, a PO4^2- is transferred from a phosphate intermediate (substrate) to ADP to form ATP. Phosphorylase and kinases are enzymes involved in this reaction. An example is the reaction in glycolysis which involves phosphoenolpyruvate and ADP to form Pyruvate and ATP. This is to ensure adequate supply of energy to cells and also during anoxia so as not to make mitochodria strain the glycolytic ATP reserves.
