Answer:
C) The two populations will evolve into separate species.
Explanation:
In the given question, the population of animals has been split into two different populations due to a natural barrier present between them.
When we will observe these species after a very long time, the species will not be able to reproduce with each other and will be reproductively isolated. This reproductive isolation will lead to the formation of new species but belonging to the same genus.
Thus, Option-C is correct.
There are exactly 24 chromosomes in a girl cell and 24 in a boy cell.
Answer:
The correct answer is ''METAPHASE I.''
Explanation:
Metaphase I is the stage in which chromosomal studies are generally performed, because its morphology is very clear. The chromosomes, moved by the mitotic spindle, are placed in the center, between the two asters and form the so-called metaphase plate, in which the chromosomes are positioned in such a way that the kinetochore of each sister chromatid are oriented towards the opposite poles. Keeping chromosomes on the cell equator implies a balance between the forces of the microtubules that tend to move the kinetochores toward opposite poles, so positioning them in the center involves a great deal of energy.In each kinetochore, between 20-30 microtubules can be anchored, which exert traction force towards the pole from which they come, so the metaphase plate is maintained by the balance between the opposite forces of the poles on the chromosomes, which hold their sister chromatids by centromeric cohesin.
Answer - Ground water erosion is a type of carbonic acidic water. That goes into the holes thru the soil and pretty much cracks thru rocks.
