Answer:
The correct answer would be option A.
Explanation:
Gina's model lacks many important factors about the particular study of damage to tree bark in the forest. This model does not explain the number of animals entering a particular area of forest.
This model does not tell, how much damage has been done. It also fails to tell what type of damage the tree has faced. It does not explain what type of bacteria evolved or carried by the animal.
Thus, the correct answer would be option A.
The right answer is Y (G2 phase).
The interphase is the moment when the cell lives and does everything for which it is programmed. She is also preparing to divide. The steps of the division are detailed below:
Phase G1 (W) comes from a word "GAP" (= interval). During this phase, the cell performs its normal metabolism, it grows to a critical size that will give the signal to move to phase S which consists of replicating the nuclear DNA (X).
Once DNA replication is complete, phase G2 begins (The letter Y). Here, the growth of the cell end, but it will continue to fulfill its functions. During this phase, the centrosomes replicate, they will allow the smooth course of the mitosis. This phase ends by passing the G2 checkpoint, where the mitosis begins.
The shortest phase (Z) is M phase (mitosis / meiosis).
(I don't know if it is the same diagram but i mean this one)
Density = Mass divided by Volume, or d = m/v.
So, replace the m and v with the amounts given:
d = 0.5.
Density = Mass / Volume
Answer:
The normal body temperature for humans is 37 degrees Celsius. Most of the enzymes of a human's bodywork best at this temperature. If an enzyme was discovered which works best at 39 degrees Celsius, then it means that the enzyme works at elevated temperatures for events which require slightly higher temperatures.
The enzyme will most probably work for overcoming fever or for reducing the temperature of the body after exercise.
Inner membrane of the chloroplasts
Explanation:
The present day eukayrotes are all considered to be derived from its original ancestor – the cyanobacteria.
Earlier, photosynthesis by the first photoautotrophs took place utilizing hydrogen sulphide as the electron donor. However, it was later when the cyanobacteria, which were originally residing in the mitochondria of an eukaryotic cell under an endosymbiotic relationship, developed into true chloroplasts, the use of water as electron donor to perform photosynthesis began.
The cyanobacteria were aerobic in nature and required oxygen to survive. They evolved the chloroplasts covered with an external protective membrane and an internal membrane. It is the internal membrane which contains all the necessary organelles or components necessary for photosynthesis like thyllakoids, stroma etc which helped them to utilize water as an electron donor during photosynthesis like all the eukaryotes.
