If you had attached some options to choose it would have been much easier to give you the correct answer. Anyway, I think I know what you are talking about. So, as far as I concerned the <span> phenomenon which occurs when a particular allele will either be expressed or silenced, depending on whether it is inherited from a male or a female is called </span>genomic imprinting.
Answer:
Kingdom Protista.
Explanation:
This is a perfect behaviour of a slime mold which is known to be of the kingdom protista. Slime molds are usually found in lawns, and on the forest floor, deciduous logs and soil too.
Protists are made up of eucaryotic cells in which the cell structure is complex with a well defined nucleus. Some of them move around with their flagella or by forming pseudopodia also known as their false sheet.
Answer:
The larva gets dark pigment.
Explanation:
If scientists purposely injected an excess concentration of these proteins in the larva, the larva gets deep dark colour because this protein is responsible for the pigment colour in the larva of Drosophila. By increasing the protein concentration the pigment will also have a very dark colour. So we can conclude from this that increasing the amount of protein causes increase in the pigment colour.
Answer:
Prezygotic barriers:
1. Habitat isolation
2. Behavioral isolation
Explanation:
Pre-zygotic barriers are the barriers which do not allow the formation of the zygote in the organisms.
The two mechanisms of the pre-zygotic barriers are the:
1. Habitat isolation: the Flycatchers do not share the same habitat which is also mentioned in the question that they live on different islands.
2. The behavioural isolation: the Flycatchers could have evolved the different mating rituals as a result of which the could not interbreed.
Thus, Habitat isolation and Behavioral isolation are correct.
