Osmosis causes water to move from areas of low salt concentration to areas of high salt concentration. The internal NaCl concent

ration of red blood cells is 0.9 M. The diagram below shows red blood cells submerged in solutions of four different NaCl concentrations—0 M, 0.65 M, 0.9 M, and 2 M. Which of the diagrams shows red blood cells in the 2 M solution?

<span>Red blood cells normally have a biconcave shape (picture a donut, but instead of a hole through the centre there's just a downward slope to the centre of the cell). If the cell takes on water, it will increase in size and the sloped areas will start to flatten out. If the cell loses water, it will begin to shrivel. Use these observations and your understanding of osmosis to answer the question!</span>

You haven't given us the diagrams, but in case you're asking about the shape, imagine this: a disc, with a sunken centre, starting to resemble a donut.

In a low salt solution, the cells would start to absorb water, thus, inflating, up to the point of resembling spheres, and even bursting in the end. In case of a salty solution like the one you proposed, blood cells would lose water and would become a bit amorphous. In the attached pic you can see a standard blood cell (on the left), and a cell submerged in a salty solution (on the right).

What are the four important conditions of a respiratory surface
Ksivusya [100]

The four important characteristics of respiratory surface are:

1. Thin walls

2. Moisture

3. Large surface area

4. Blood supply

Respiratory system or respiratory tract is divided into upper and lower tract. Upper respiratory tract includes nose and its cavities, sinuses, pharynx and the part of the larynx. Lower respiratory tract consists of the trachea, bronchi, bronchioles and the alveoli.

Alveoli are the ends of the respiratory tract the smallest units in it. Alveoli are small folded air sacs that are branching off from alveolar ducts and providing an extremely large surface area for the gas exchange. Gas exchange occurs thanks to small blood vessels – capillaries that surround alveoli and it occurs via the process of diffusion.

So, respiratory surface is thin membrane also known as the blood–air barrier that consists of the alveolar epithelial cells, their basement membranes and the endothelial cells of the alveolar capillaries.

Arlecino [84]
I’m not sure that your choices are because it says select all that apply but I would tell the mother to stop giving the baby cows milk. The baby needs more iron which is in breast milk or formula if not she can become anemic and cows milk is not easy to digest for babies.
