Correct answer:
"<span>B- homologous chromosomes join together to form tetrads during prophase I"
</span>It is during prophase I that homologous chromosomes join together (<span>synapsis)</span> and form tetrads - four chromatids are together in the new structure of two chromosomes - and this is the reason why crossing-over occurs in this phase. It is in this tetrad that both arms of both chromosomes may crossover and matching regions exchange places. This process results in homologous chromosomes recombination leading to genetic variability.
The prokaryote cell has cytoplasm the other one doesn’t
You could’ve attached a question or a picture or something
I would go for 'c'. The reason being, is that it doesn't do much, and I am also assuming that offshore drilling will not affect underwater sources, which are linked to the ocean.
Answer:
S phase.
Explanation:
During this phase, the DNA within the cell is also copied during this process.
