Explanation:
<span>The answer to the question is 0 percent. In order to have wrinkled seeds, the offspring must inherit two recessive alleles from the parents. From the cross of RRYY and RrYy, there is no way for the offspring to have wrinkled seeds as one of the parents doesn't have the recessive gene for it, the RRYY parent. Because of this there is 0 percent probability of having an offspring that has wrinkled seeds and yellow seed color.</span>

Explanation:
Plant cells have cell walls around them, and animal cells don't have cell walls. The cell walls give plant cells their boxy shapes. That's nice for plants, because it gives them the ability to grow up and out, where they can get lots of sunlight for making their food.
The nucleus maintains the integrity of genes and controls the activities of the cell by regulating gene expression- the nucleus is, therefore, the control center of the cell.
Answer: c. The Earth’s surface is responsible for a small fraction of heat radiation to space.
Explanation:
In later ages the large amount of sun's energy is reflected back by the terrestrial surface back to the space. But now due to the abundance of large concentration of greenhouse gases in the atmosphere is responsible for the absorption of thermal energy from sunlight by these gases causing the atmosphere to be hot. This is the reason of global warming. Now only small fraction of heat is radiated back to the space.
