Answer:
from glycolysis to electron transport.-glycolytic pathway
NADH and FADH2 are the major electron carrier from glycolysis through the Kreb Cycle to the electron transport chain.
Note-NADH alone transports electron from glycolysis to the Kreb Cycle. while both NADH and FADH2 transport electrons from the kreb'cycle to the electron transport chain.
from citric ac id cycle to the electron transport chain.
as explained above both NADH and FADH2.
The electrons are in the hydrogen atoms, carried by these co-enzymes. When they reached the matrix, the hydrogen atoms are split into protons and electrons(p and e-). it is these electrons that form gradients which are transported as chains in the matrix. The gradients of the electron generated PMF for pumping Hydrogen atoms into the intramembrane of mitochondrial
Note.
Nicotinamide Adenine Di nucleotide Hydrogen(NADH)
Flavin Adenine Dinucleotide Hydrogen(FADH)

Option D
Explanation:
Options for the question
A)import seeds produced in the southern hemisphere.
B)plant the flowers out-of doors in november.
C)keep the plants in a warm growing environment.
D)expose the plants to an hour of light in the middle of each night until the end of april.
Solution
Since Chrysanthemum is a short-day plant, its flower mainly develop during night and hence they require long nights of 11 to 12 hours. Blackout system is sometimes used to induce flowering.Flowering can be delayed by regulating both light and temperature. this is done by exposing plants for a short period of time to light (can be artificial) and to some source of heat that produces 85° F or higher temperature.
Thus if flowers are required in month of may, flowering can be delayed by exposing Chrysanthemums plant to light and heat source during night time
Option D is correct
Answer:
This is an illustration of epistasis type of gene interaction.
Explanation:
On crossing AaBb * AaBb, the offspring produced are mentioned in the Punnett square given in the attachment below. Based on the Punnett square, the phenotypic ratio will be 9 (orange): 4 (cream) : 3 (yellow).
The given case is an illustration of the epistasis kind of gene interaction. When two or more distinct gene loci take part in the formation of similar phenotype, however, not additively is termed as epistasis, that is, it is the non-allelic association between the alleles situated at a distinct gene locus. In the phenomenon of epistasis, one of the gene loci modifies or masks the phenotype of a second gene locus.
They are unique in the sense that sawfish are able to reproduce in the wild without the need of a partner. They were able to engage in asexual reproduction. In parthenogenesis, an egg cell is created by dividing a singular precursor cell into four separate ones. The cell that develops into an egg cell retains the cytoplasm and other vital cellular structures. The remaining three contain excess genetic material.
Fertilization happens when one of the three extra cells essentially turns into a sperm cell and combines with the egg cell.
