Explanation:
The blood plasma must be isotonic to maintain the health of red blood cells. Isotonic means that the concentration of solutes (like salts and proteins) in the plasma is the same as the concentration inside the red blood cells. This balance is crucial for several reasons:
1) Osmotic Balance: An isotonic environment prevents water from rushing into or out of red blood cells. If the plasma were hypertonic (higher solute concentration), water would leave the cells, causing them to shrink and become dehydrated. If it were hypotonic (lower solute concentration), water would enter the cells, causing them to swell and potentially burst. Isotonicity maintains the ideal osmotic balance.
2) Cell Shape and Function: Red blood cells have a characteristic biconcave shape, which increases their surface area for oxygen and carbon dioxide exchange. Maintaining an isotonic environment helps preserve this shape. In hypertonic or hypotonic conditions, the cells can become distorted, compromising their ability to transport gases effectively.
3) Hemoglobin Function: Hemoglobin, the protein responsible for carrying oxygen in red blood cells, relies on an appropriate ionic balance to function optimally. Changes in plasma tonicity can affect the ability of hemoglobin to bind and release oxygen.
In summary, an isotonic blood plasma environment is essential for the health and proper function of red blood cells, ensuring they can efficiently transport oxygen and carbon dioxide while maintaining their structural integrity.
Answer:
Distance of Jupiter from sun in kilometers is km
Explanation:
Given,
The distance of Jupiter from sun in astronomical unit (AU)
One astronomical unit (AU) Kilometers
So, in order to convert AU into kilometers , the distance in AU should be multiplied with total kilometers in one unit of AU
Thus,
Distance of Jupiter from sun in kilometers
Answer:
Trees soak up rain from the ground and store/use it. Without trees to soak up the water on the ground, it stays put > pools > floods.
Also, a little bit of rain stays on the trees' leaves. This may not seem like a lot, but there are many trees in a forest with many many leaves all holding water :)
Explanation:
Hi there!
A lion eating a zebra is an example of growing and developing, since the energy and proteins that have been transferred to the lion from the zebra help the lion grow.
Hope this helps!
The water molecule has the ability to form hydrogen bonds, between atoms of oxygen and hydrogen of different molecules (they can also be formed between atoms of hydrogen, phosphorus, and nitrogen, but in the case of water we refer only to hydrogen and oxygen). When this phenomenon occurs between molecules of the same species (one molecule of H2O with another molecule of H2O), it is called cohesion, which is the attraction that molecules have for others of the same type. In the case of water, cohesion occurs thanks to hydrogen bonds, and this union is very strong and difficult to break.
