The presence of paired chromosomes makes a <u>diploid </u>cell, while a single member of a pair of chromosomes makes a<u>haploid </u>cell.
Diploid cells. Meiosis is the process of cell division by which involving gametes. Cell division is just the same for sperm and egg cells, but they have distinguishable descriptions and labels in the process. Spermatogenesis is for the males’ sperm cells and oogenesis is the process for females’ egg cells. The cell division of meiosis involves the two phases, respectively meiosis I and meiosis II. Meiosis I like mitosis is the cell division that produces diploid cells<span>. These diploid cells are cells that contain a complete pair of chromosomes which is 46. The result is two diploid cells after the first meiosis. To provide clear explanation, in contrast haploid cells only contain 23 chromosomes and are created after meiosis II which is 4 in number. </span>
Answer:
All living things can breathe air
Explanation:
Fishes dont breathe air, and yet theyre very much living things.
Having two copies of the mutated genes cause sickle cell anemia, but having just one copy does not, and can actually protect against malaria - an example of how mutations are sometimes beneficial.
The majority of mutations have neither negative nor positive effects on the organism in which they occur. These mutations are called neutral mutations. Examples include silent point mutations. They are neutral because they do not change the amino acids in the proteins they encode.
Hope this helped :)
Plants with just one cotyledon are said to be monocotyledons. They also include floral segments that are multiples of three. This implies that their blooms may be made up of sepals instead of petals, or they may have three, six, or nine petals. Additionally, they have accidental roots. These are roots that may sprout from nearly any portion of the plant that comes into touch with the soil, such as the stem.
For instance, garlic plants, spiderwort, etc.
Answer: The correct answer for the fill in the blank is B) RNA and Proteins.
Ribosome is a molecular machinery, which is located in all living cells. It is formed from proteins and complexes of rRNA ( ribosomal RNA). That is why, it is also called as ribonucleoprotein.
Ribosome serves as the site for protein synthesis. It is primarily divided into two subunits, a larger ribosomal subunit and a smaller ribososmal subunit, which together assist the process of protein formation ( translation).
Thus, the components of ribosomes are RNA and proteins.
