Homeostasis involves maintaining balance of several factors that make a cell healthy. The job of the cell membrane is to regulate the passage of materials into and out of the cell. In order for any materials to go in or out of the cell, they must cross through the cell's membrane.

Hope this helped

homeostasis is the internal balance of the human body. the cell membrane maintains a stable internal environment by balancing the pH, temperature, glucose, and water balance

BigorU [14]

The cautions that can be given to the friend include the following:
Eating foods from different sources is very advantageous because it ensures that one gets all the necessary food nutrients that are needed for proper growth and development. Getting the necessary food nutrients on the other hand will boost one's immunity and enable one to develop resistance to diseases. Restricting one's food to a limited type of food is very bad and can have fatal consequences.

Sladkaya [172]

Lipid Bilayer.A plasma membrane is made up of Lipid Bilayers, which consists of polar phosphate heads, which are hydrophilic or water loving, and non-polar fatty acid tails, which are hydrophobic. Proteins are embedded in the membrane as well.Cell membranes are known to have holes, or selective permeable.

The expression of a trait is directly dependent on the

Lemur [1.5K]

Answer: B

Explanation:

The question wants to know what the expression is directly dependent on.

The sequence of genetic expression goes like this:

DNA -> RNA -> protein

If we want to know the root cause of expression, we must look at the DNA, not the RNA or protein, because DNA determines the RNA and protein expression.

The Shape of subunits in DNA -> Sequence of bases coded for by the ribosome with RNA -> Arrangement of amino acids in the protein synthesized.

Why not C: Number of chromosomes present isn't a factor, because most humans, barring those with a genetic disorder, have 23.

Peripheral resistance depends on all of the following factors except __________.

pantera1 [17]

Options for the question have not been given. They are as follows:

blood vessel length

blood viscosity

blood vessel diameter

blood colloid osmotic pressure

Answer:

blood colloid osmotic pressure

Explanation:

Peripheral resistance is the resistance to blood flow by blood vessels.
It is directly proportional to blood vessel length as more the distance to travel, more will be the resistance.
It is also directly proportional to blood viscosity as more energy is required to push viscous material.
It is indirectly proportional to blood vessel diameter. More the diameter of the vessel, easier it is for the blood to pass.
However, it does not depend on blood colloid osmotic pressure. Colloid osmotic pressure is created by the protein components of blood and they do not have any direct impact on blood flow.
