If the answers are different lab tools, then a scientist would use a microscope to exam and study details of protein molecules most likely
Answer:
Explanation:
This is due to the fact that water has high specific heath capacity,which makes it to accommodate large amount of heat energy produced by the catabolic reactions which liberated heat.
General, the amount of heat energy needed to raise the temperature of a particular substance over a given amount is called the specific heat capacity of that substance. Therefore for water, the amount of heat energy needed to raise the mass of 1kg of water by 1 degree is called the specific heat capacity of water.
Since large hydrogen bonds held water molecules together,it takes a long time of heat energy to break these bonds free to raise the temperature of water.Hence, water in living cells is able to accommodate large amount of heat energy to stabilise the temperate of the cells.
The correct answer is gliding joint.
<span>
A gliding joint or a plane joint is a type of synovial joint formed between bones that meet at flat or nearly flat articular surfaces. These joints allow the bones to glide past one another in any direction along the plane of the joint (twisting, turning, and sliding). </span>
Answer:
A. synthesis of vitamin C.
Explanation:
Integumentary system refers to the skin and its appendages. So it doesn't have the role to synthesis vitamin C, but it can synthesis vitamin D through exposure to UV light. The major role of integumentary system is protective role (immuno defense-from infections, dehydration, temperature changes, protection of underlying tissue etc). It also contains many receptors (for pain, touch, temperature change) that detect environmental changes.
Wow that's a good one :). Think about it like this. When you put antibiotics in place where bacterias live, probably most of them will die, however there might be "some" who are resistent to the antibiotic by their nature, (mutations etc.) so among the bacterias which were exposed the antibiotics those resistent ones will survive. And bacterias have a system for exchanging DNA to make each other more resistant, its called "conjugation" look it up. By conjugation they give each other genes which will help them survive. So if we summarize, those who are already resistant survive (which is a cause of natural selection in an environment of antibiotics) and help others resistant too.
