How are cell structures adapted to their functions?

Biology
2 answers:
Olegator [25]3 years ago

Answer: Cell structures adapt by responding to their environments as a group, and evolve over time.

Explanation:

Skin Cell Adaptation : Has many nerves that allow you to sense your surroundings, and allows you to hold and absorb many important nutrients.

Nerve Cell Adaptation : Nerve cells have very long axons being they can deliver messages for a longer time before passing it on to the next cell, which makes this process significantly faster.

Muscle Cell Adaptation : These cells have adapted to their function by being able to increase their size based on the work they do on a regular function.

Red Blood Cell Adaptation : When it removes the carbon dioxide from your body, it moves it to your lungs to exhale.

Answer:

Explanation:

A cell is adapted to its function because of differential expression of genes during fetal development during which they get differentiated and determined to provide division of labour to different tissues. They contain protein fibres that can contract when energy is available, making the cells shorter.

Chloride ions, Cl-, follow actively transported Na+ ions from the nephrons into the blood. Would you not expect the Cl- concentr
DerKrebs [107]

Answer:

Bicarbonate ion, HCO3- (which has a similar charge to chloride ions) also follow sodium ions into the blood. Also, potassium ions, K+ are transported into the nephron so some chloride ions and bicarbonate ions remains in the nephron to balance the charge.

Explanation:

Sodium is the primary positively charged electrolyte in extracellular fluid. Most of the solute reabsorbed in the proximal tubule is in the form of sodium bicarbonate and sodium chloride. Water is also reabsorbed in order to balance osmotic pressure

When sodium ions are reabsorbed into the blood, few of the substances that are transported with Na+ on the membrane facing the lumen of the tubules include Cl- ions, Ca2+ ions, amino acids, and glucose. Sodium is actively exchanged for K+ using ATP on the basal membrane.

In the distal convoluted tubule, K+ and H+ ions are selectively secreted into the filtrate, while Na+, Cl-, and HCO3- ions are reabsorbed to maintain pH and electrolyte balance in the blood.

Some chloride ions remains in the nephron to balance the charge of the secreted K+ ions and also due to the bicarbonate ions that are removed.

As you may know, people’s physical and emotional health interact: One can affect the other. The characters in "In Another Countr
Margaret [11]

Answer:

To preserve their mental health, the characters must keep in mind that all suffering is temporary and although it is difficult, they will overcome this situation. What can help characters deal with their situations is by reasoning about the following questions:

"What led me to this situation?"

"What are my limitations in dealing with this type of problem?"

"How could I have acted to minimize the impacts of suffering?"

"Would any action by me prevent these disorders?"

Explanation:

Every time that the characters evaluate themselves and correct their behaviors, they will be able to follow the emotional evolution that will help them to deal with all their suffering. In this journey, each one has a different rhythm. In fact, we are different in almost every aspect of our physical and mental makeup. The variations in intelligence are enormous and also those related to aggressiveness, intensity of fears and the ability to deal with them. It would not be fair, therefore, to tell a character (or a person) that he is suffering from "nonsense". What is small for one may be large for the other. Underestimating the pain of others is not synonymous with help, but a lack of empathy.

We do have a duty and obligation, in the name of our own well-being, to try to get rid of our pains as quickly as possible, but that does not mean not feeling them. Some people do it more easily, while others "fall in love" with the problem and think about it in a recurrent and obsessive way. They silence the word, but the mind goes on chattering.
