Answer:
Primary spermatocytes are always diploids
54 × 2 = 108
Explanation:
Primary spermatocytes are diploid (2N), meaning they have a full set of DNA; having a full set of chromosomes. They thus undergo meiosis to form two haploid (N) secondary spermatocytes containing half of the DNA. Therefore, the primary spermatocytes will have 108 chromosomes.
Answer:
These two processes are related because what's produced by one is needed for the other.
Explanation:
In photosynthesis, O2 and glucose are produced. Autotrophs (and heterotrophs too) use cellular respiration to make carbon dioxide and water from organic compounds - glucose - and oxygen; therefore, we can say that the glucose and oxygen are acting as reactants in the process of cellular respiration.

Hope i helped you
Answer:
A
Explanation:
If we compare a whale to a house fly, You can clearly state a whale is much larger. Looking at the life span of both of these organisms, House flies have a pretty brief lifespan (they live up to about 4 weeks) while a Blue whales life span ranges from 80-90 years.So, with that being said, I believe A is your correct answer.
