Answer:
Plants need to excrete excess carbon dioxide and oxygen. Carbon dioxide is a waste product of aerobic respiration in plant cells. Oxygen is a waste product of photosynthesis .
Answer:
Explanation:
Ccrm is a DNA methyl transferase. This enzyme helps in switching from fully methylated stated to hemimethylated state at its target motif. In this way this gene helps in expression of genes which helps in controlling the cell cycle progression.
When the Ccrm gene is found to be non functional in form. Then there is no switching occur from fully methylated to hemi methylated state at its target motifs. That's why there is not found expression of those genes which are involved in the cell cycle progression. In this way there is not found replication of DNA and there is not found replication of chromosome. That's why there is found single chromatid containing chromosome even after S phase. That's why the daughter cell will not get equal amount of genetic material. And cell cycle becomes futile.
It is the variable being controlled/changed to see if there are any effects on the dependent variable (the thing getting tested/measured)
Fascia, the type of tissue that "invests" the body structure, is the Connective tissue
