Explanation:
PENIS
If the mans father could not roll his tongue, then the father has a genotype of rr.
Now if the man (the son) can roll his tongue this mean he has a genotype of either RR or Rr.
Because the father has a genotype of rr, that means the son has to have at least one allele of r.
This means the genotype of the man is Rr.
The answer is A, only cells having specific receptors...
These are just quickly written down, but I hope these can serve as sufficient answers.
Plant Behaviours:
1. - Some plants know when the sun will rise. Sunflowers are a good example of exhibiting this behavior called "Circadian Rhythm."
2. - Plants that have vines search for a surface, preferably a pole but walls are acceptable, to climb and grow on, which is called "Twining."
3. - Some plants 'curl up' whenever they are touched.
4. - Corn seeds can distinguish between 'up' and 'down,' which is called "Gravitropism."
5. - A plant can distinguish their own roots from another plant's.
Animal Behaviours:
1. - Animals can communicate, actually, they can communicate quite well! Dolphins and bees are infamous for this, as they communicate through a series of actions and the point comes across clear to others in their species.
2. - Body language is a behavior most commonly associated with animals, even though we do it too.
3. - Territorial/'Defensive' behaviors are common, such as marking and hostility when another animal trespasses into their domain.
4. - Certain behaviors are exhibited to attract/court mates, such as birds singing songs or chemicals being thrown off to lure in a partner.
5. - Cooperation is also a very common behavior, as seen in ants.
6. - Annual cycles, such as migration and hibernation.
7. - Animals also have a circadian rhythm like plants, which aids in whether or not an animal exhibits the behavior of being nocturnal.
