The father of this offspring should be male 3. It is the only individual that exhibits certain molecular genetic markers present in the offspring but absents in the mother.
<h3>Genetic markers</h3>
A molecular genetic marker is a fragment of DNA that can be used to trace the inheritance pattern from parents to offspring.
In this case, parents and offspring exhibit three molecular markers which are shared among them.
There are certain genetic markers that are present in the offspring but they are absent in one of the parents, and therefore they can be used to trace the inheritance pattern.

Hello! Your answer would be C, They regulate body temperature through behavioral mechanisms.
An endothermic animal is one which is capable of maintaining its own body temperature. They do this through physiological mechanisms, which is what the last choice is saying - these involve things such as hormones, sweating, etc.
These endothermic animals are considered warm blooded. This is because they can make their own body heat. Humans and other mammals are endothermic. We generate our own heat - we don't rely on sunbathing or shade to cool down or heat up our <u>internal</u> body temperature.
Hope this helps!
4. When you look up to the sky, it appears as a dark circle with halo light at its edges moving across the face of the sun. As it does, depending on the relative position of the person on earth – that determines where they are on the umbra or penumbra of the eclipse, the place becomes a daytime twilight (umbra) or partial twilight (penumbra).
5. A new moon is formed when the moon is in between the sun and the earth. This is converse to the case of a lunar eclipse where the earth is between the sun and moon. In a new moon, the face of the moon that is faced towards the earth is dark because it is not lit by the sun. It is important to note that a solar eclipse is not formed because the moon’s orbit, around the earth, is tilted at an angle.
Scientists so far haven’t managed to figure that out .
