Answer:
When the cell has 0% sucrose I expect the cell to stay the same.
Explanation:
First of all, this question should not be confused for the statement "When the "cell" has 0% sucrose, did you expect the cell to have gained water, lost water, or stay the same. In this case, the correct answer would have been; gained water.
But, in this question, we are asked what happens to the cells at 0% sucrose concentration. At 0% (no solute) concentration, there is no net movement of water or solute into or out of the cell, because the cell is isotonic to the external environment (distilled water). Osmosis, a special kind of diffusion, is the movement of water, from areas of lower solute concentration to area of higher solute concentration, or from areas of higher water concentration to areas of lower water concentration through a semi-permeable membrane. If the water moves into the cells (hypertonic cells), then the cell gains water and increases in size, but if the cell loses water (hypotonic cell), then it reduces in size
Answer:
B. Enzymes generally catalyze only very specific biochemical reactions.
E. Most enzymes are proteins composed of amino acids
F. The cells of both eukaryotes and prokaryotes all contain enzymes.
G. If the active site of an enzyme is altered, the enzyme is unable to catalyze the biochemical reaction.
Explanation:
Enzymes refers to substances that acts as a catalyst in living organisms. They regulate the rate at which chemical reactions proceed without being altered in the process. Enzymes regulate the biological process that occur within living organisms.
Enzymes catalyze all aspects of cell metabolism such as digestion of food, conservation and transformation of chemical energy and the construction of cellular macromolecules from smaller precursors.
Application of enzymes
1. Industrial application
2. Medical application
1. Enzymes can be used for industrial application such as beer brewing, wine fermentation, bread leavening.
2. Enzyme can also be applied in the medical aspects for killing disease-causing microorganisms, promoting wound healing, and diagnosing some diseases.
<span>Endoplasmic Reticulum
ER Golgi apparatus, because it packages proteins received from the ER cytoplasm </span>
<span>The Golgi body are the ones that slightly alter, organize and prepare so-called parcels to be delivered for all the organelles in the cell. They receive these packages mainly in the rough endoplasmic reticulum. These packages that set out by Golgi body are macromolecules that used and synthesized by cells in many operations. If ER is absent then it would only mean that Golgi body would have no use other than simply lysosomes but these macromolecules plays a dynamic role in many organelles –nutrients, ATP and cell metabolism. It'll have a ripple effect if ER is absent in the cell.<span>

take long showers
Explanation:
Answer:
Two European men and two Polynesian women settled on a previously uninhabited tropical island. All four of the settlers have brown eyes, a dominant trait, but one of the Europeans is heterozygous and carries the recessive gene for blue eyes. No new settlers arrive,and nobody leaves the island.After a few generations,the percentage of blue-eyed individuals increases from the original zero to 25 percent.This is probably due to which of the following factors?
genetic drift
Explanation:
Genetic drift entails when there are changes in the gene frequency which occur in a gene that is existing. From the analogy above, it is a known fact that only gneetic drift could allow such to happen as mutation will only occur with a sudden change of gene which is not the case described above
