Answer:
By panting or breathing heavily.
Explanation:
<em>An ectothermic animal is one whose body temperature depends on the temperature of the external environment.</em>
The body of ectotherms regulates temperature depending on the temperature of the external environment where such animal finds itself.
Hence, when the temperature of the external environment rises as a result of hot air, the body of an ectotherm (that is homeothermic, that is, maintain a relatively constant body temperature irrespective of the temperature of the external environment) will adjust so as to keep its temperature relatively constant.
Dogs generally pant (breathe heavily) to bring their body temperature back to normal whenever it rises beyond normal due to rigorous physical activities or high external temperature.
<em>Hence, a fox will most likely pant in response to hot air temperature just like dogs.</em>
The ATP enables the movement of transport proteins to move the ions across a cell membrane by its getting fueled by its hydrolysis
<u>Explanation:</u>
The plasma membrane is a semi permeable membrane that is the movement of molecules across the membrane is constricted. There are 2 types of moment across the plasma membrane one is the active transport and the other is the passive transport. The active transport involves the help of ATP whereas the passive transport does not involve ATP to transport the materials.
I believe the correct answer is: HIV is spread during unprotected sex or through contact with infected blood; it cannot be cured, but early treatment can minimize the long-term consequences.
<h2>Explanation:</h2>
Human Immunodeficiency Virus is a type of virus which causes an impairment of the immune system of the person making them susceptible to diseases such as tuberculosis, influenza and any other disease that can exploit this opportunity. It is spread by a person coming into direct contact with infected bodily fluids such as saliva during deep kissing, semen during intercourse, blood after an accident or even fluids when sharing needles and syringes for drug addicts. There is no cure but the current form of treatment slows down the virus to prevent some consequences.
<h2>Further Explanation:</h2>
The virus is enters the body through open wounds or surfaces such as the vagina or mouth where the skin is very thin and can tear. After penetrating the skin, it attaches to specific immune cells called CD8+ T-cells on points called receptors. It then enters the cell and replicates itself in the nucleus of the cell and as it goes out, it kills these immune cells making the person to have a weak immune system. The current drugs used called AntiRetroVirals (ARVs) such as the drug Zidovudin stops the virus from replicating thus reducing the total amount of virus in the body called the Viral Load. Some drugs target enzymes called proteases and reverse transcriptase that help the virus to replicate. This viral load is what is counted to estimate the total volume of HIV someone has in their body. Infected persons should use protection while having sex and also avoid sharing sharp objects to prevent transmission. They also need to take their medication to make them much more healthier in addition to taking proper balanced diets.

Answer:
Ribosomes are the machinery of protein synthesis in the cell. They are associated with different organelle of the cell. They are also found free-floating in the cytoplasm of the cell.
The organelle which ribosomes interact are plasma membrane in prokaryotes and endoplasmic reticulum(ER) in eukaryotic cell. Ribosomes are present on the surface of the ER and helps in protein synthesis in the ER. In prokaryotes, there is no ER so it is associated with plasma membrane and perform protein synthesis.
The specialized function of ribosome is to perform protein synthesis and these proteins are necessary for cell because protein are important to make enzymes that regulate the metabolism of the cell. So if protein synthesis stops cell will not able to perform important metabolic activities to survive and it will die.
Having a large number of ribosomes benefits cells because it fastens the protein synthesis process in the cell. So large amount of protein can be produced in less time.
