<h3><u>Answer;</u></h3>
The bacteria require less energy to make offspring,
They do not need a partner
Also the reproduction is faster and rapid compared to sexual reproduction.
<h3><u>Explanation</u>;</h3>
- Asexual reproduction is a type of reproduction that involves one parent and produces offspring that are genetically identical to each other and to the parent.
- In sexual reproduction, on the other hand, two parents are involved, who produce reproductive cells called gametes that unite to form an offspring.
- <em><u>E. coli is a bacteria that reproduces asexually. An asexual reproducing organism can produce many offspring in a short period of time without utilizing energy to find a mate</u></em><u>. </u>
Make/produce and secrete hormones
Answer:
Explanation:
Meiosis is a form of cell division that occurs in the sex cells of organisms. It ensures the reduction of a diploid cell to an haploid cell to allow for the formation of a diploid zygote after fertilization (contribution of both parents haploid sex cells to give a diploid zygote). Thus, this process is very essential and important.
The reduction is accomplished by 2 divisions after the duplication of chromosomes
- first division: separation of homologous pairs of chromosomes (this reduces the total in half)
- second division: separation of sister chromatids of a chromosome.
The rearrangement in meiosis occurs by crossing over/genetic recombination.
This is the exchange of genetic material between homologous pairs of chromosome bringing about a rearrangement and genetic variation
An example of a chromosomal abnormality that arises as a result of defects in this process is the Down Syndrome which is caused by a nondisjunction of the chromosomes 21 pair in a sex cell.
This condition produces offsprings that have some characteristic facial features, short stature etc
