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.
The procedure by which the female gametes or ova are produced is known as oogenesis. The female gamete is known as an ovum. The process of oogenesis begins in the embryonic stage, the development of ovum takes place from the primary oocyte by maturation.
Each of the primary oocytes goes through the process of meiosis to generate one ovum. Thus, two primary oocytes will produce two ova after going through meiosis.
Yes, C4 is a process used by plants to survive in hot dry climates along with the CAM cycle. Hope this helps!
During the citric acid cycle, the
production of co2 is the result of the oxidation of intermediate compounds of
the citric acid cycle coupled to the production of ATP/GTP.
<span>The
citric acid cycle has an essential role in metabolism, and it consist of series
of steps. The citric acid cycle is also known as Krebs cycle. One other name of
this cycle is Tricarboxylic Acid (TCA)cycle.</span>
