Explanation:
<span>Compound Microscope
Compound microscope is commonly used in the schools and colleges.
It comes under the category of microscopes used in biology.
It has two lenses namely the objective lens and the ocular lens.
It provides a magnification of 1500X.
Eyepiece lens is of 10X or 15X power.
It is used to observe bacterial, protozoa, various cells, etc.</span>
Answer: The blanks can be correctly filled up with prophase I and metaphase II.
Explanation:
In females, finite number of oocytes are present since birth. The process of oogenesis initiate in embryonic stage only. However, oogonia divide and mature to form primary oocytes. These primary oocytes start meiotic division but arrest in prophase I stage before birth.
After a girl attains puberty, one primary oocyte resumes its division each month during a menstrual cycle. The primary oocyte divides to form secondary oocyte and polar body.
Polar bodies degenerate after completing meiosis II. However, secondary oocyte halts its division again at metaphase II until fertilization takes place. Once fertilization takes place it completes its meiosis II and results into mature ovum and polar body.
Carl Woese distinguished between the members of the archaea and the bacteria using studies of their ribosomal RNA.
What is ribosomal RNA?
Ribosomal RNA (rRNA), a particle in cells that are sent out to the cytoplasm and is a part of the protein-creating organelle known as a ribosome, supports the change of courier RNA (mRNA) into protein. Moreover, ribosomal ribonucleic corrosive is a type of non-coding RNA that fills in as the primary structure block of ribosomes, which are essential for all cells. Protein combination is done by rRNA, a ribozyme, in ribosomes. In spite of never being converted into proteins, it makes up around 80% of cell RNA.
