Meiosis is a cellular division that produces four haploid daughter cells from a parent cell. It is observed in gametes/sex cells. The process of meiosis undergoes two consecutive divisions. Each division has five phases: prophase, metaphase, anaphase, telophase, and cytokinesis.

In Meiosis I, the chromosomes of the parent cells are multiplied. Each chromatid of the chromosomes exchanges genetic information, or recombination. The number of chromosomes at the end of Meiosis I is haploid but the chromatids of the chromosomes are still attached to each other. Due to recombination, the sister chromatids may not be identical to each other.

In Meiosis II, the chromosomes are separated and produce four daughter cells. It is shorter compared to Meiosis I because it no longer replicates the DNA or exchanges genetic information, and just separates the prepared chromatids from Meiosis I. It is similar to mitosis since it begins with a haploid cell and ends with a haploid cell.

Mutations are not always negative. Explain why this statement is true. Provide two reasons using examples to support your answer

Rainbow [258]

2 examples -
1.) in italy, ( limone ) a unique mutation protects them from developing atherosclerosis,
2.)theres mutation in bacteria too, this mutation allows bacteria to survive in the presence of antibiotic drugs, leading to the evolution of antibiotic-resistant strains of bacteria.

Human papillomavirus (HPV) is a double-stranded DNA virus that enters the cytoplasm before undergoing uncoating. Although the vi

Roman55 [17]

Answer:

Basal cells, keratinocyte

Explanation:

The viral DNA replication is inhibited until Basal cells are differentiated into keratinocyte, which are ready to be shed from the epithelial layer, increasing the likelihood that HPV will be transmitted to a new host.

95% of the cells in the epidermis are keratinocytes

Basal cells are multipotent stem cells that are important in the regeneration of homeostasis of the respiratory epithelial cell population.

in skin growth, most of the cells are keratinocytes and they are formed by the division of stem cells in the basal layer

N76 [4]

Answer:

there is an association between the number of mitochondria in muscle cells and energy production

Explanation:

Mitochondria generate energy by generating adenosine triphosphate (ATP), which is referred to as the "molecular unit of currency" of the cell since this molecule provides energy for diverse cellular processes
