Answer:
Form a hypothesis
Explanation: This should be the correct answer. Hope this helps :)
When a virus attaches to a host it insets its rna into the cell and uses transcriptase enzyme to make it into dna and start producing more of its self. Once’s produced enough releases vessicles that secrete many more virus and repeat the process once they attack to a cell
The pattern of embryonic development in which only the cells lacking yolk subsequently undergo cleavage is called meroblastic development, which is typical of birds.
Therefore, the correct answer is Option D.
<h3>What is embryonic cleavage?</h3>
- Embryonic cleavage is the division of cells which occurs just after fertilization and are involved in the early development of the embryo.
- The different cells formed after cleavage are called the blastomeres and these are present in a compact mass called the morula.
- The end product of cleavage is blastula which is a hollow sphere with a cavity called blastocoel.
- Cleavage can be of different types depending upon the concentration of yolk in the egg as yolk does not undergo cell division.
- In holoblastic cleavage, the entire egg divides as yolk is present in very less concentration.
- In meroblastic cleavage, only the cells lacking yolk divide.

Explanation:
The pioneer species are hardy species which are the first to colonize barren environments or previously biodiverse steady-state ecosystems that have been disrupted, such as by fire. Meanwhile,the climax community, or climatic climax community, is a historic term for a boreal forest community of plants, animals, and fungi which, through the process of ecological succession in the development of vegetation in an area over time, have reached a steady state.
