Answer:
Given that a negatively charged rod is brought closer to two metal spheres which are in contact with each other as shown: So, free electrons from rod will be attracted towards the metal spheres.
The type of reaction that build proteins from amino acids are dehydration reactions
Creatinine is a by-product of muscular metabolism. In the natural and normal scheme of things, this substance or waste product can be eliminated from the body. A high-serum creatinine level may cause kidney damage. In relation to the above question as to how high can creatinine levels go before death, it must be noted that kidneys have strong compensatory ability and by that as long as its still 50 percent functional, creatinine level won't be that high. Which leads us to a conclusion that, the lesser the kidney function level is, the higher the creatinine level.
On the other hand for the blood urea nitrogen (BUN) is the most stable blood constituent following death as it reaches antemortem (before death) levels and even after moderate decomposition.
Therefore, as long as the kidneys are functional, regardless of other factors such as the patient's condition/ diagnosis, these blood constituents are nearly normal.
Answer:
It depends...
Explanation:
Group 1 is trying to obtain energy, so as we know that lipids and carbohydrates are the basic source of energy because of their storage properties and generation of ATP during glycolysis and lipid metabolism in our body.
Group 2 is trying to obtain nutrients so to rebuild their molecules and body cells they must take enough quantities of vitamins/minerals for that. Proteins are also crucial to for rebuilding lipo-proteins in cell wall of cell amke them crucial for them. They also play an important role in muscle cell repair and replacement due to their primary composition of actin and myosin filaments.
I believe your answer would be:
A. Fossils.
Explanation:
Because they are the preserved remains or traces of animals, plants, and other organisms from the past. They're also important evidence for evolution because they show that life on earth was once different from life found on earth today.
Hope I helped, good luck! =)
