statocytes, organelles do plants have in their roots that helps them to sense gravity, correct answer is B.
what are statocytes ?
In higher plants, statocytes are the cells which sense gravity. They contain amyloplasts-statoliths, amyloplastic organelles which are filled by starch or sediment at the bottom of the cells. Coleoptiles, shoots, and inflorescence stems all have an elongating area that really is home to statocytes.
how do they help in sensing gravity ?
When the plant is reoriented in the gravity field, the starch-filled plastids (also known as statoliths) in the statocytes, that are highly polarized cells, fall to the physical bottom.
Hence, statocytes help in sensing gravity.

I think mitosis if I’m wrong correct me. But we also have other answers so idk.
Electrolyte imbalance can affect the normal function of the brain. Sodium is an important electrolyte maintains homeostasis in the body. Its primary function is to regulate water retention. Low sodium usually decreases serum osmolality. This combination of deficiencies is called Hypotonic hyponatremia.
A sudden drop in sodium and plasma osmolality can cause seizures. Brain function is affected because the water in the body, because start to flow from the extracellular spaces into the intercellular spaces. This causes the brain cells to swell and thus affecting its normal function.
Therapy for this type is IV therapy, particularly hypertonic saline to replace the sodium in the body and normalize plasma osmolality and diuretics are given to aid in water excretion. Therapy should be done slowly and should be closely monitored. More swelling can developed when it is done too quickly.
Answer:
A. 14.59
Explanation:
Firstly, rounding a number means making a number simpler but keeping its value close. So rounding 14.587020 means making it look less complex but making sure the rounded value is within range of the original value.
Next, we have to know that to round a number;
* Digits below 5 (<5) rounds down the next digit to their left i.e. we leave the digits the same and turn the rounding digit to 0.
* Digits above 5 (>5) rounds up the next digit to the left i.e. we add 1 to the next digit
Next, to round to 4 significant digits means we want to see only the first four non-zero digits in our value. Note that, all non-zero digits i.e. 1-9 are significant
Hence, 14.587020 will be:
= 14.587020
= 14.58700
= 14.59000
We have four (4) digits which are non-zero already, hence we stop here and remove all zeros to the right
Hence, 14.587020 to 4 significant digits is 14.59 i.e. 14.587020 ~ 14.59
