Composed of a phosohlipid bilayer

Answers

Answer 1

Answer:

The cell membrane is composed of a phospholipid bilayer.

The cell membrane is primarily composed of a mix of proteins and phospholipids

Phospholipids are a major component of cell membranes. They a head and a tail. The head is hydrophilic (attracted to water) and the tail is hydrophobic (repelled by water).

They form a bilayer in which their hydrophilic heads face the aqueous cytosol and extracellular fluid while their hydrophobic tails face away from the cytosol and extracellular fluid.

The lipid bilayer is semi - permeable

This will disrupt the ecosystem of the forest because the gazelles will compete for limited food resources and possibly exhaust them. In this scenario, what type of species are cheetahs?

Bacteria live in groups called colonies. Colonies are usually circular. The diameter of a particular bacterial colony is 12 mm. The circumference of a circle is equal to pi (3.14) times the diameter (C = pi times the diameter)1.What is the circumference of the colony?
2.What is the radius of the colony

Answers

The circumference would be 37.68 mm, and the radius is 6 mm.

Answer:

the circumference is

3.14 times the diameter or

3.14 x d

since d is 8 the equation becomes

3.14 x 8 = 25.12 mm in circumference.

Bones act as a frame to which _____ are attached for movement.cartilage
organs
striated muscles
cardiac muscles

Answers

The three types of muscular tissue are skeletal, smooth and cardiac. Skeletal muscles are muscles which are attached to the bone. Their main function is to help with skeletal movements. The smooth muscles are also known as involuntary muscles. We are unable to control their movements. It is found in the walls of organs such as the stomach and the bronchi. Lastly, the cardiac muscle is the heart muscle. It is only found in the walls of the heart. Structurally, it is a combination of the skeletal muscle type as well as the smooth muscle type

i know this is late but the correct answer is the cardiac muscles
