Why does protein concentration increase from the arterial blood to the postglomerular blood

siniylev [52]

Proteins have a very high molecular weight and cannot be present as macro molecules in the glomerular blood. Before even reaching the blood, they are well masticated and processed to simple amino acids and other nitrogenous compounds like urea, uric acid etc. (in the digestive system itself). They are eliminated from the body while glomerular filtration through urine. The glomerular blood thus becomes free from such compounds before leaving the kidney.

What is a diffusion through plasma membrane?

yan [13]

Diffusion is the movement of particles from a high concentration area to a low concentration area. Things that can go through a membrane are ions (charged), small polar molecules. Big molecules can't go through the membrane due to its large size and disrupting the membrane. Passive transport is the movement of substances acrpss the cell membrane w/o the use of energy. Active transport needs energy to move substances across a cell membrane.

A parent cell gives rise to daughter cells with identical genetic information. Which of the following data supports the idea tha

Yuri [45]

Answer:

A feline skeletal muscle cell undergoes cell division, resulting in two feline skeletal muscle cells.

Explanation:

We are looking for a parent cell that gives rise to daughter cells with identical genetic information.

In simpler words, we are looking for something that makes 'clones' of itself.

In this statement (second option), the parent and daughters are all feline skeletal muscle cells.

A feline skeletal muscle cell undergoes cell division, resulting in two feline skeletal muscle cells.

Other incorrect choices: (All having to do with reproduction).

A child has brown eyes; one of its biological parents has green eyes, and the other has brown eyes.

This situation has two parents, each with a different trait. The child takes one of the parent's trait. The parents did not make a 'clone' of themselves.

A human sperm fuses with a human egg cell, resulting in the development of a new human.

The parents don't make 'clones' of themselves. The sperm did not make more sperm. The egg did not make more egg cells.

A long-stemmed plant reproduces with a short-stemmed plant, and the offspring are all long-stemmed.

The offspring plant only took the trait from one of it's parents. Also, whole plants are not individual cells.
