How would the contractile vacuole of a freshwater amoeba respond is the organism was placed in seawater

Biology
1 answer:
morpeh [17]3 years ago
3 0

The major function of the contractile vacuole of amoeba is osmoregulation. The solute concentration found in the cell of amoeba's cytoplasm is more than the solute concentration in the freshwater that surround the external part of the organism, thus, water enter the cell through osmosis. The contractile vacuole collect the excess water and expel it through an opening in the cell membrane. By doing this, the contractile vacuole maintains the water balance in amoeba. This how the contractile vacuole normally operate.

In a situation where amoeba is placed in seawater, then water from the cell cytoplasm will rush out of amoeba cell, because of the higher salt content of the surrounding medium. The contractile vacuole will respond to the situation by increasing its contraction and pumping water out the cell in an accelerated manner, this will lead to the shrinking of the cell.

Lelu [443]

Answer:

The provided question is incomplete as there is no option available however the generalized answer would be -

The correct answer would be - For treating the global symptoms related to the allergies, it is known as that the inhaled nasal steroids are far more effective than oral medications.

Explanation:

Nasal steroids are the steroids that relieve congestion problems by decreasing the inflammation in the nose of an individual. These are then inhaled by the nose which directly sprays into nasal passages.

In comparatively the oral steroids take time to show their impact on the individual and even the impact is considered not as effective as the inhaled nasal sprays.

Thus, the correct answer is - For treating the global symptoms related to the allergies, it is known that inhaled nasal steroids are far more effective than oral medications.

What can you do to ensure that you will continue to be motivated for the duration of your fitness program?
avanturin [10]
1. Make a goal for yourself. When you finish your fitness program(achieve your goal) you can reward yourself with like icecream or a small treat.

2. Make working out fun so that you will keep wanting to do it. For example, work-out or go to the fitness program with a friend, listen to music while doing it, etc.

3. You can make yourself motivated by watching fitness videos and basically watching things to get inspiration(trust me this works).After you watch the vids, your gonna want to keep going to the fitness program cause of all the benefits and things like that. 

4. Ask a friend or someone to push you to keep going(if all else fails and you wanna quit) They will annoy you so much that it would just be better to go to the fitness program than hear them annoy you.

5. Think why your going to regret not going. This is gonna make you want to go to the fitness program.

6. Honestly if the others don't work, do it for the pictures and so that you can brag to people that you work out and stuff.

That's all I got for now. Hope it helped motivate you to keep going to that fitness program <span />
