A male drake will result with XY chromosome and a female drake would have XX chromosomes
Answer:
guard cells
Explanation:
they control the opening and closing of the stomata
Answer:
Seafloor spreading helps explain continental drift in the theory of plate tectonics. When oceanic plates diverge, tensional stress causes fractures to occur in the lithosphere. At a spreading center, basaltic magma rises up the fractures and cools on the ocean floor to form new seabed.
Explanation:
Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor. Eventually, the crust cracks.
Answer:
The DNA must be replicated first to be a whole chromosome since at the previous division it was only a set of two "half" chromosomes.
Explanation:
Mitosis never replicates DNA which is split in half in a set pattern every replication to prevent mutations.
The use of restriction enzymes is evidenced by the statement 'cut site mCYCF3E 685' (Option A).
<h3>What are restriction enzymes?</h3>
The restriction enzymes are proteins (enzymes) that cut specific sites in the nucleotide sequence.
In this case, the enzyme cuts the gene mCYCF3E at the position number 685 (nucleotide base).
In conclusion, the use of restriction enzymes is evidenced by the statement 'cut site mCYCF3E 685' (Option A).
