The answer is A
He grouped organisms that shared obvious physical traits, such as number of legs or shape of leaves.
Answer:
trocophore larva
Explanation:
The trocophore larva is a marine planktonic larvae. The mollusca, annelida, and nemerteans shows trocophore as larval stage.
The trocophore larva shows similarities with invertebrates group of organisms. This similarities provide evidence that bilateral symmetry organisms evolved from radial symmetry. The larva represents a transitional stage in ctenophore emergence. There are close similarities in trocophore larva and annelid larva (echinoderm). Thus, a close evolutionary relationship between annelids and mollusks is suggested by the presence of a <u>trocophore </u>larva in both phyla as well as by molecular sequence comparisons.
Oxygen will diffuse more quickly into cell B because the diffusion gradient there is steeper.
The concentration gradient depicts the slow change in the concentration of solutes found in a solution between the two regions. A gradient in biological terms arises due to an unequal distribution of ions across the membrane of the cell. Both the process of facilitated and simple diffusion take place when there is a concentration gradient.
Answer:
C) are sequence-specific DNA endonucleases
B) degrade foreign DNA that enters a bacterium.
Explanation:
Restriction enzymes are the proteins that cut the DNA at a specific sequence.
<u>Restriction enzymes are also known as restriction endonuclease produced by bacteria that recognizes a specific sequence on DNA and split it by catalyzing the hydrolysis or addition of water molecule. </u>So, Restriction enzymes are sequence-specific DNA endonucleases.
The biological role of restriction enzymes is to restrict the entry of foreign DNA into the bacterium. <u>Restriction enzymes have the ability to restrict the number of bacteriophage strains that affect bacteria.</u>
Hence, the correct options are "C and B"
