(G1) - The stage where the cell spends most of it's life. Doing it's job (job being what the cell was created for, such as being a muscle or bone cell.) and being alive.
(S) - S phase is where cell performs synthesis (Hence the name of the stage, S.) and duplicates it's nutrients and everything inside it, most importantly though you must know that this is the stage where DNA is copied.
(G2) - This is the stage where the cell is preparing to entire mitosis, it's also known as the pre-mitotic phase. This phase takes place immediately after DNA has been replicated in the S phase. After the G2 phase is finished, mitosis begins.
This response is important because it enables the plant to increase its intake of carbon dioxide. Carbon dioxide is an important gas,during the process of photosynthesis, where plants use energy from sunlight to make simple sugars and release oxygen. This is also a way of absorbing carbon dioxide (a green house gas) from the atmosphere thus reducing its amounts.
For the trait that is coded by a recessive allele to be expressed, the must be homology, which means that an offspring has to inherit that recessive allele from both its parents.
A dominant allele will dominate over the recessive allele, so for the trait coded by a dominant allele to be expressed, the offspring only needs to inherit the allele from one of its parents.
For example: "R" is brown eyes, "r" is blue eyes.
Now you get one R from each of your parents.
RR (homozygote) = brown eyes
Rr (heterozygote) = brown eyes
rr (homozygote) = blue eyes
If temperatures are too high, the leaves from these delicate plants will whilt and die. If there is too much rain, the leaves will fall off and the plant will lose it natural beauty. High temperatures affect animals because the can become too dehydrated and can lack energy and strength, this can be negative if they are being hunted. Too much rain affects animals because they can struggle to find shelter in the rain and can get caught up in an overflow of muddy water.
Answer:
Polyploidy arises as the result of total nondisjunction of chromosomes during mitosis or meiosis.
