B) The species has 16 sets of chromosomes per cell.
C) Each cell has eight homologous pairs.
D) During the S phase of the cell cycle there will be 32 separate chromosomes.
E) A gamete from this species has four chromosomes.
For a species with a chromosome number of 2n=16, each cell has eight pairs of homologous chromosomes. There are not 32 chromosomes, 16 sets, or four chromosomes in a gamete.
In biology, the chromosome number 2n=16 indicates that the organism is diploid and has 16 total chromosomes, which are organized into 8 homologous pairs. So, the correct answer is option C) Each cell has eight homologous pairs. The number 16 (2n) represents the total number of chromosomes, not how many sets there are, making option B incorrect. One should not interpret this to mean there are 32 chromosomes in total, so option A is also incorrect. During S phase of the cell cycle DNA replication happens, but this doesn't change the number of chromosomes, just the number of DNA molecules, therefore, option D isn't right. Lastly, a gamete (sex cell) from this species would have n=8, or half the number of chromosomes, contradicting option E.

is the same as mitosis
Answer:
The cytochrome b6f is a large multisubunit protein, which accepts electrons from the PLASTOHYDROQUINONE. One electron moves linearly toward PLASTOCYANIN , while the other goes through a cyclic process, which effectively pumps more PROTONS into the thylakoid lumen.
Explanation:
Cytochrome b6f plays a very important role in photosynthesis reaction in plants.
Cytochrome b6f exists as a dimer and it is an multisubunit protein that can be found in the chloroplasts of plants.
Cytochrome b6f speeds up the movement of electrons plastohydroquinone to plastocyanin during photosynthesis.
Answer:
The cytochrome b6f is a large multi-subunit protein, which accepts electrons from the plastohydroquinone.
One electron moves linearly toward plastocyanin while the other goes through a cyclic process, which effectively pumps more protons into the thylakoid lumen.
Explanation:
The cytochrome b6f is distributed among both grana and stroma thylakoids equally. They are usually large and embedded in the membrane.
b: a phosphate group, a pentose sugar, a carboxylic acid
c: a pentose sugar, a nitrogen base, an R group
d: a nitrogen base, an amino acid group, a carboxylic acid
Answer:
a phosphate group, a pentose sugar, a nitrogen base
Explanation:
nucleic acid is a polymeric macromolecule made up of repeated units of monomeric 'nucleotides' composed of a nitrogenous heterocyclic base which is either a purine or a pyrimidine, a pentose (five carbon) sugar (either ribose or 2′-deoxyribose), and one to three phosphate groups.
Prevailing winds are the surface winds that blow from a specific direction. The prevailing westerlies move much of the weather across America and Canada. Thus, option A is correct.
Prevailing westerlies are the type of prevailing windsthat are also called anti-trades. These winds blow from the west towards the east and lie between 30 and 60° latitude.
The prevailing westerliesaffect the climate and the weather of the US and Canada as it brings colder air during the summers and warmer during the winters.
Therefore, the prevailing westerlies determine the weather of the US and Canada.
