Answer:
cytoplasm consists of up to 90% water and Its main function is to hold together the organelles which make up the cytoplasm.
1. B. A process in which electrons are transferred from one compound to another with a release of energy occurring in the production of ATP
2. A. The gel-like material within a living cell
3. D. An organic molecule that occurs as an intermediate in many metabolic processes
4. C. The chemical breakdown of a substance
Answer:
See attached picture
Explanation:
An optimal temperature graph plots the rate of the enzyme reaction against the temperature. We know that the optimal temperature of this enzyme is 37C, so we know that at this temperature, the rate will be highest.
Additionally, there will be a minimum temperature required for the enzyme to work at all, which is why the line graph slowly increases the rate until its optimum at 37C.
Finally, at higher temperatures, the enzyme will become denatured and its activity will be diminished. This is why the activity drops at high temperatures and is non-existent at very high temperatures.
Answer:
Lysosomes
Explanation:
Death is a process that consists of different phases that lead to the decomposition of the body. One of the first phases, which occurs minutes after death, is the process known as autolysis, which begins once the cells are deprived of oxygen.
During autolysis, the body's enzymes begin to digest the membranes of the cells, breaking down the whole cells. This process is initiated by organelles known as lysosomes, which are in charge of releasing these enzymes that are involved in the 'digestion' of the human tissues.
Answer:
C. After many generations, the offspring of the introduced guppies with mature at an older age and larger size because of selective pressure from the new predator.
Explanation:
In the above scenario evolutionary biologists found variation in guppies with average age and size due to selective pressure from the predators including pike cichlids and killifish. As cichlids preys larger guppies primarily and killifish preys smaller guppies but with killifish, it has been found that guppies reproduced at older age and larger at maturity.
So, because of selective pressure, the new generation of guppies will be mature at an older age with increase in size.
