arsen [322]

Answer:

Prions archea, viroids bacteria, viruses protists are acellular while fungi is cellular.

While viruses have indeed been closely researched for more than a century for infections of people and animals, most viruses, particularly those that infect microorganisms, are still poorly understood. 

Pathogenic RNA molecules are known as viroids. Contagious protein particles are identified as prions. Viruses are larger than that of viroids. Viroids are larger than prions in size.

Molds, wild yeasts, as well as mushrooms are examples of fungi. Numerous fungi are multicellular and also have nuclei in their cells. A protein-encased DNA or RNA core defines viruses being non - cellular organisms. Some scientists disagree with the notion that viruses are living things.

D genetic variation among the daughter cells is increased

E two identical daughter cells are produced

Answer:

D. genetic variation among the daughter cells is increased

Explanation:

Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. Meiosis occurs in germ cells, as a result; genetic variation among the daughter cells is increased. These cells (germ cells) are our sex cells – sperm in males, eggs in females.

In meiosis, the haploid gametes that are produced are not identical in their allelic composition.

In prophase 1, the chromosome pair up.

During metaphase, The chromosome pairs line up next to each other along the center (equator) of the cell.
