Receptors that are embedded on the cell membrane bind to chemicals outside of the cell and this binding process cause a chemical response on the inside of the cell.
These receptors that help in communication between the cell and the outside world are called cell surface receptors or sometimes transmembrane receptors.
A majority of chemical signals are water soluble thus unable to cross the fatty lipid bi-layer of the cell membrane. Their receptors, which are protein in nature therefore must span the membrane, detect their presence outside of the cell and transmit this information into the interior of the cell.
Answer:
Dark yellow ,small volume pea.
Infrequent pea.
Dry mouth and tongue.
Sunken eyes.
Dehydration is a condition in which the rate at which the body looses t fluids is higher than the rate at which it takes fluids in.
It is caused by diarrhoea( watery stools )
2.Excessive sweating.
3 vomiting continusly.
4. No access to water intake
5.Polyuria(excessive urination)
6.Fever leading to hyperthermia.
The kidney is the main organ where the effect of dehydration is managed . As a result of increase in the solute potential of the blood,;the hypothalamus secrets ADH hormones which stimulates the Aquaporins(transmembrane proteins in the collecting duct and the distal convoluted tubules) to open .Therefore water moves in by osmosis to reduce the higher solute potential of the blood. Therfore low volume,high concentrated urine is produced.
This homeostatic function of the kidney ensures balanced in the electrolyte fluids of the body to manage dehydration,before medical intervention.
Explanation:
The question has options that are given as below:
A. Some potatoes would be more likely to have a genetic resistance to the disease and survive. B. The potatoes would have been able to trade genes so that they could survive the disease. C. More of the potatoes would have been edible varieties. D. None of the potatoes would have been infected by the disease.
Answer:
The correct answer is - A. Some potatoes would be more likely to have a genetic resistance to the disease and survive.
Explanation:
Genetic resistance is the capability or ability of some individual organisms of a population or species have to adapt the environmental or genetic changes and survive while other organisms of species are not able to do the same.
In this case, some of the potatoes more likely to show genetic resistance to the disease and condition and survive from the devastation of the potato blight
