Answer:
a) Photosystem I requires the use of light converting an excited NADP + electron, reducing it to NADPH. In photosystems I and II, the passage of electrons to a series of redox reactions will be shown due to the absorption of light energy by the chlorophyll molecules.
(b) The control must be RuBisco, because for most photosynthesis responses to light, temperature and carbon dioxide, it produces oxygenation and carboxylation reactions, thus reflecting kinetic properties.
(c) plants can increase the ability in a variable ecosystem thanks to the flexibility of photosynthetic pigments, through these the necessary solar energy for photosynthesis is captured, according to each light spectrum there will be a specific pigment.
Answer:
D). genetic drift
Explanation:
Genetic drift is the change in an allele frequency over a period of time. This event has to be random and a chance event.
For example: In a population of a flowering plant there are two types of flowers, blue and yellow. Due to a fire many yellow flowers are destroyed by chance. Now the resultant population will have more blue flowers and when they reproduce the population will eventually evolve to have more blue flowers. Effect of genetic variation is more pronounced in a small population since its easy to disturb the allele frequency.
That's because they are in the same climate zone. The earth's climate zones change going from the north pole to the equator, and then from the equator to Antarctica, like a mirror image. The two are found in the same zones on the opposite hemispheres.
Answer:
B, C, D
Explanation:
The following statements are true regarding the continental crust;
It is between 25 and 70 km thick
Its made of all types of rocks
It contains silicate minerals high in sodium, potassium, aluminum, and calcium
Because that destroyed it so it could be more helpful
