Membrane phospholipids are arranged in a bilayer with hydrophilic heads on the

Biology
1 answer:
kicyunya [14]4 years ago
5 0

Answer:

A.) the phospholipid heads can interact with water inside and outside the cell

Explanation:

The cell membrane is mostly composed of phospholipids which form a bilayer due to the properties of the phospholipids. The phospholipids are made up of phosphate heads, which are hydrophilic and attracted to water, and fatty acid tails, which are hydrophobic and repelled by water.

Due to these properties, a bilayer arrangement forms spontaneously, with the heads being attracted to the water both inside and outside the cell, and the tails being repelled by water and clustering together inside the bilayer

This regulates the passage of materials into and out of the membrane - some substances can easily pass, others are blocked from entering

Wall of stomach : it has three layers of muscle instead of two. Under these muscle layers is the adventitia, layers of connective tissue continuous with the omenta. The epithelium of the stomach forms deep pits, called fundic or oxyntic glands.

wall of ileum : The wall itself is made up of folds, each of which has many tiny finger-like projections known as villi on its surface. The ileum has an extremely large surface area both for the adsorption of enzyme molecules and for the absorption of products of digestion.

tino4ka555 [31]

Answer:

yes

independent - temperature

dependent - amount of sugar dissolved

Explanation:

When water molecules are heated they move faster and collide more with the sugar molecules. These collisions transfer energy to the sugar molecules. Energy is needed to break bonds. The bonds holding the sugar molecules together or more likely to be broken.

The amount of sugar dissolved is dependent on the temperature of water.

DNA contains the template needed to copy itself, but it has no catalytic activity in cells. What catalyzes the formation of phos
inna [77]

Answer:

DNA polymerases

Explanation:

The formation of a phosphodiester bond between adjacent nucleotides is catalyzed by the DNA polymerases. They do this efficiently only if the incoming base on the incoming nucleoside triphosphate is complementary to the base on the template strand and can bind efficiently.
