The correct answer is option 4, that is, muscle cells require more energy, so they have more mitochondria in comparison to the skin cells.
Mitochondria are the powerhouse of the cells. The synthesis of ATP takes place in them, that is, the energy currencies of the cell. The cells of the muscles need to work hard and thus require ample energy, for this, they need more concentration of mitochondria to generate a high energy yielding ATPs.
Cholesterol refers to a fat-like waxy substance, which is found in all the cells of the body. The body needs some cholesterol to produce hormones, substances that assist in digesting foods, and vitamin D. The body produces all the cholesterol it requires.
Cholesterol enhances the fluidity of the membrane, which otherwise comprises majorly the long-chain saturated fatty acids.
Cholesterol minimizes the fluidity of the membrane in the regions known as rafts that comprise huge concentrations of cholesterol and sphingolipids.
Answer:
Covalent Bonds
Explanation:
The nature of the interaction between the atoms depends on their relative electronegativity. Atoms with equal or similar electronegativity form covalent bonds, in which the valence electron density is shared between the two atoms.
