Answer:
Only Photosystem I - 1, 5, 6
Only photosystem II - 3, 2
Both Photosystem I and II - 4
Explanation:
Only Photosystem I
a) Reduction of NADP+ - uses light energy to convert NADP+ to NADPH2
b) Reduction of electron transport chain between the two photosystems
c) Oxidation of electron transport chain between the two photosystems.
Only photosystem II
a) Oxidation of water - here the absorbed light energy is used to dissociate of water molecules to produces protons (H+) and O2 along with free ions
b)Reduction of primary electron acceptor - An electron is taken by pheophytin which is a primary electron acceptor molecule that is located within photosystem II and hence it get reduced.
Both Photosystem I and II
a) Light is absorbed in both photosystem I and II. While in photosystem I, light waves of large wavelength i.e 700 nm are absorbed, in photosystem II light waves of short wavelength of i.e 680 nm are absorbed.
Over 90% of all parasympathetic fibers are derived from the cranial nerve X, which is the vagus nerve.
The vagus nerve influences most organs below the neck. The activation of this nerve affects heart rate, blood pressure, production of stomach acid, movement of food through the intestines and breathing.
Answer:
This happened because the check points in cell cycles are not working properly which can help to stop cells having abnormal chromosomes.
See the attachment for proper understanding what actually happened in cell cycle check points.
Answer:
The correct answer would be phenotypic variation.
Phenotype refers to observable traits or characteristics of an individual. For example, height, color, shape, et cetera.
Phenotypic variation refers to the sum total of variations in characteristics within populations of the same species.
In contrast, genotypic variation refers to the sum total of variations (such as allele frequency) present in the genome of populations of the same species.
Answer:
1) lysosomes
Explanation:
because, they involve in intracellular digestion
