Answer:
the pH
Explanation:
The condition that should not be kept the same in each of the five test tubes is the pH.
Since <u>the aim of the experiment is to investigate the effect of pH on the activity of the lipase enzyme</u>, the pH is, therefore, the <em>independent variable</em>. Thus, it must be controlled or varied in all the test tubes in order to see its effect on the activity of the enzyme, which, in this case, would be the dependent variable.
The answer would be C because people destroying rain forests for homes and resources are diminishing animal homes and animal population <span />
Answer:
Skin cell has 10 chromosomes.
Sperm cell has 5 chromosomes.
egg cells has 5 chromosomes.
Explanation:
If the fruit fly egg has 5 chromosomes, then the skin has 10 chromosomes because skin has diploid i. e. double number of chromosome. There is always haploid or half number of chromosome present in the sex cells such as sperm and egg cells of any organism. When the sperm and egg cells fuse together they formed the organism which is a diploid i. e. double number of chromosome.
Answer:
D. Inhibits the degradation of 2,3-BPG, thereby increasing its concentration in erythrocytes
Explanation:
A pharmaceutical company trying to develop a drug that improves tissue oxygenation by increasing the percentage of oxygen that is released from hemoglobin during its passage through the capillaries of extrapulmonary tissues. This drug, it is hoped, would become a popular doping agent for athletes.This means that the company should try a drug that Inhibits the degradation of 2,3-BPG( 2,3-Bisphosphoglycerate) , thereby increasing its concentration in erythrocytes
The correct answer is signal transduction.
Signal transduction also called cell signaling refers to the conduction of molecular signals from the external of the cell to its internal. The signals perceived by the cells must be conducted efficiently into the cell to make sure an effective response. This step is stimulated by cell-surface receptors.
There are three phases in the procedure of communication or cell signaling, that is, reception, transduction, and response.
