The only one correct answer would be:
c. Yellow or red hues in the soil indicate the presence of iron or aluminum.
Answer:
a
Explanation:
an insoluble substance which is the main constituent of plant cell walls and of vegetable fibers such as cotton. It is a polysaccharide consisting of chains of glucose monomers
In the heterozygous state (w +/w), a variegated eye is produced, with white and red patches. The following statements are true in relation to this experiment:
b. When heterochromatin spreading does not reach the new location of the w + allele, the gene will be transcribed, producing red eye patches.
c. When heterochromatin spreading encompasses the new location of w + allele, the gene is transcribed, producing white eye patches.
d. Even though eye color phenotypic variegation exists within the eye, all cells have the same genotype.
Explanation:
Heterochromatin in droshophila has genes which gets expressed by position effect variegation. In some normally active cells genes are silenced in some due to transposition of genes which causes change or variegating in phenotype.
This change is due to change in position of the gene in the genome and chromosome but no change in gene.
The variegation in drsophilla melanogaster shows that white gene was not damaged.
The rearrrangement of gene takees place at pericentric heterochromatin.
Heterochromatin is required for maintaining genome integrity and regulating gene expression. When spread in neighboring region it can inactivate the genes present there.
The genes taking part in variegation remains same hence no change in genotype.

Answer:
Anaerobic respiration does not proceed to the electron transport chain
Explanation:
Aerobic respiration occurs when oxygen is available. When oxygen is available, glycolysis is followed by the Kreb's cycle and then the electron transport chain. The electron transport chain produces the vast majority of ATP during respiration.
The electron transport chain proceeds when there is the presence of oxygen because oxygen acts as the final electron acceptor in the electron transport chain.
When there is no oxygen to act as the final electron acceptor, the cell must undergo anaerobic respiration, which does not involve the electron transport chain, producing much less energy. See the attached diagram for a picture!
