Answer:
Explanation:
Compact bone aka cortical bone is a dense, solid and rigid in which bony matrix with ground org. Substances and salts densely filled and leave tiny spaces known as lacunae. These spaces contain osteocytes also called as bone cells. Inside of these osteons there is a central canal which supplies blood vessels and nerves within bone. These vessels provide blood to the spongy bone and living cells housed within compact bones.
Structure of Compact bone: Basic unit of Compact bone is called osteon also known as haversian system. Each osteon consist of four parts.
1. Haversian canal which consists blood vessels and nerves acts as a site of hematopoiesis which is one of the functions of Compact bone.
2.lamellae are concentric rings of strong matrix consisting Calcium and phosphorus. this gives the bone its strength and hardness to bear body weight.
3.Lacunae contains osteocytes.
4.Canaliculi links osteocytes and provide route for nutrients to reach osteocytes.

idk idk idk im not genios
Answer:
The correct answer would be His mitochondria lack the transport protein that moves pyruvate across the outer mitochondrial membrane.
In cellular respiration, glycolysis takes place in the cytoplasm of the cell and converts glucose into 2 molecules of pyruvate. Pyruvate is then transported into the mitochondria for further oxidation.
It is transported into the mitochondria with the help of transport protein pyruvate translocase where it is decorboxylated to produce acetyl-CoA. This acetyl-CoA then enters the Krebs cycle to produce ATP (adenosine triphosphate) with the help of oxidative phosphorylation, electron transport chain and chemiosmosis.
In absence of this transport protein, the cell can not completely oxidize the glucose or carbohydrate. It switches to the metabolism of fats and amino acids in order to meet the energy demands of the cell.
the answer is B cholesterol, which is a direct product of the steroid nucleus.
