Answer:
b. less
Explanation:
Dogs have been bred to live in a man-generated environment: they are particularly adept at reading human social cues.
The talents with which they excel - understand when they point to something or identify objects - are largely the result of humans having spent thousands of years educating them to understand important concepts for us.
We have molded them according to our definition of intelligence.
On the other hand, dolphins have developed their cognitive abilities in a world not altered by humans.
Even so, they seem intelligent because their complex social behavior reminds us of ourselves.
Dolphins are perhaps non-primate animals more similar to humans, and that is why we consider them intelligent.
But a dolphin's brain has evolved to produce behavior that helps it deal with dolphin problems.
That includes the ability to find fish buried in the sand with echolocation or sleep with only one half of the brain at a time to get to breathe to the surface.
Another factor is the hereditary lineage from which living beings come. Canine animals have a genetic lineage much closer to humans than dolphins.
Preganglionic fibres originate in the sacral region off the spinal cord.
According to the research, the correct option is during normal cell division. Vertical gene transfer is the transfer of dna during normal cell division.
<h3>What is
Vertical gene transfer?</h3>
It is the one that occurs when genes normally during cell division are transmitted within the same species, that is, from their ancestors from the parental gene to the progeny, as in the case of bacteria that occurs by binary fission when bacteria duplicate.
This transfer of genetic material from parent organisms to offspring is through reproduction within the same species.
Therefore, we can conclude that according to the research, the correct option is during normal cell division. Vertical gene transfer is the transfer of dna during normal cell division.

Answer: Apocrine sweat gland produce a substance that is more oily than sweat from other sources.
Explanation: Apocrine glands are one of the glands in the body that are found in the skin and eyelids as sweat glands,in the ear they secrete earwax and they secrete milk droplets in the breast.
Body odour is the product of bacteria, environment dirts and sweats that accumulates in the skin. Stress can also be a cause of body odour and this happens when we excercise or engage in stressful activities,unlike the eccrine glands in our body that produces watery sweat, apocrine glands that are mainly found in the ampits and groins which produces fatty sweats which are always triggered by anxiety, when these apocrine glands produces fatty sweats, these fatty seats are higher in protein making it easy for bacteria to break down,the bacteria in these areas (groins and ampits) are exposed leading to body odour.
