Answer:

Explanation:

1. The cell is present in some type of cells. It is found in plants and bacteria and some others. It is present or found outside the plasma membrane.

2. The functions of cell wall are that it provides tensile strength and protection to the cell against many type of stress. It also plays very important role in many others protections for the cell. There are two layer, named as primary cell wall and secondary cell wall.

3. Composition of Plant cell walls is that they are primarily made of cellulose. Cellulose fibers are linear long polymers of around 100 molecules of glucose. These fibers cluster into bundles, known as or called microfibrils. In plants the microtubule cytoskeleton are present, and there function is that they directs the orientation of cell wall as in which orientation cellulose is deposited in the cell wall.

A hypertonic solution has:

BaLLatris [955]

A hypertonic solution has:

Fewer water molecules outside the cell than are inside the cell. Thus, option "A" is correct.

<h3>What is hypertonic solution?</h3>

The cell is in a hypertonic solution because it lost water through osmosis and shrunk.
A hypertonic solution contains more solute molecules compared to solvent molecules while the hypotonic solution has more solvent molecules than solute molecules.
When a plant cell is placed in a hypertonic solution it loses water through osmosis and shrinks.
An animal cell placed in a hypotonic solution absorbs water through osmosis, increases in size and then bursts. Plant cell, on the other hand, does not burst when placed in a hypotonic solution as it contains a cellulose cell wall.

Thus, option "A" is correct.

vekshin1

The icd-10-CM codes is International Classification of Diseases, Tenth Revision, Clinical Modification.

The icd-10-CM is used for the clinical manifestation of the diseases or the abnormalities detected during the treatment procedures. These codes are used for the reimbursement purpose of the treatment or the diagnostics provided.

B83.8 is a code for the hepatic capillariasis. The code B83.8 is used for billable diagnostics in the case of Helminths infection.

So, the given blank can be filled with B83.8.

The presence of a meal in the stomach triggers an increase in the colonic motility and an increase in the frequency of mass move

34kurt

Answer: Gastrocholic reflex

Explanation:

The gastrocholic reflex or gastrocolic response is one of the physiological reflexes in the stomach which controls the movements like peristalsis and motility in the gastrointestinal tract.

This reflex is generated by the the food particles that enters the stomach. The bolus of the food in the stomach helps in the mass movement of the other food particles in the colon.

This reflex is known as gastrocholic reflex.

What can you learn about a sample from an sds-page analysis?

puteri [66]

Option <u>(c.) the purity of the protein</u>, will be the right one.

Sodium Dodecyl Sulphate provides a negative charge to each protein as a function of their molecular size. It is an anionic detergent, as well as it is there to determine the relative abundance of major proteins.

After denaturing, proteins get unfolded and gets coated with SDS detergent molecules. The SDS-PAGE technique is used for the separation of protein based on their molecular size/weight/mass.

It is so because as it identifies the proteins by its molecular weight. Therefore, SDS is used in denaturing polyacrylamide gel electrophoresis for the determination of protein molecular weight, the SDS-PAGE is a technique.
