B. Plants
Explanation:
Plants are the main producers of the world's total oxygen output into the atmosphere.
Oxygen is a by product of photosynthesis in plant.
- During photosynthesis, green plants manufacture their food using carbon dioxide and water in the presence of sunlight.
- They produce glucose in the process.
- The by product of this process is oxygen gas.
- Oxygen gas is released into the atmosphere by this process.

There are choices for this question namely:
a. Fungi rely on the wind to disperse their spores, whereas plants have multiple means of dispersal.
b. Spores do not have their own nutritional supply and often do not land in a suitable environment that provides nutrients.
c. Spores are produced asexually and so are less genetically robust.
d. Animals eat the developing mushrooms before they have a chance to mature.
The correct answer is that spores do not have their own nutritional supply and often do not land in a suitable environment that provides nutrients. Spores more often than not transported through air and lands randomly, usually in an unsuitable environment. Spores also do not have their own nutritional supply unlike seeds of plants which contain endosperm as nutrient source.
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.
