Answer:
In Interphase The cell grows in the (G1) phase, replicates DNA in the (S) phase
then prepares for mitosis in the (G2) phase. This all happens in Interphase. Hope this helps!
Explanation:
Answer: By the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes. The recombination of chromosomes creates genetic diversity by allowing genes from each parent to intermix, resulting in chromosomes with a different genetic complement.
During respiration, the diaphragm moves upwards and returns to dome shape from the flattened shape before during expiration.
This movement of diaphragm can decrease the lung volume, increase the pressure inside and thus force the air out. This process is expiration.
However, if we breathe in again, which makes that inhalation, the diaphragm moves downwards into a flat shape so that it can increase the lung volume and thus we can breathe in as much air we can. This process is completely opposite from expiration.
Answer:
Plants must have evolved in a manner where they require less water and nutrients as these two were the only limiting factor and carbon dioxide was in abundance
Explanation:
Some 400,000 years ago, the concentration of CO2 was very high and was near to 1000 ppm. At this high concentration of CO2 the photosynthetic activity of plants becomes very high and thus since 400,000 years ago plants could have evolved in an uncontrolled manner but this does not happened. So the reason behind this is limitation in terms of soil and its constituent’s nutrients availability and also limited supply of water.
Therefore, if plants would have evolved themselves in a manner where they require less water and nutrients then they would have grown limitless.
A soil sample from a temperate deciduous forest would be more nutrient rich that a sample from the tropical rain forest.
In the rain forest the tree tops form a canopy and the tops of trees absorb 90% of the sunlight and only 10% can get down to the understory which is the area under the canopy. The soil is very nutrient poor.
In a temperate deciduous forest there is no canopy so more sunlight can get to the soil. Which makes it more nutrient.
