Answer:
HIV destroys helper T cells
Explanation:
The evading viruses destroys helper T cells or the CD4+ thus the body can no longer stop some infections. The secondary infections also called opportunistic infections are rampant with people who have AIDS. This is because helper T cells help fight against most infections in the body.
Answer:
The option that says: Sister chromatids separate from each other and migrate to opposite ends of the cell.
Explanation:
This question wants to test us on a very interesting part in genetics that is Cell Cycle, Mitosis and Meiosis.
In mitosis, the cell divide to produce or generate two daughter cells that has the identical genetic infomation just as the one in the parent cell. After mitosis, we have Cytokinesis.
For meiosis, it is divided into two that is meiosis I and meiosis II. Meiosis I is about the separation of homologous chromosomes pairs while meiosis II is about the separation of chromosome into two chromatids.
In anaphase II of meiosis, "Sister chromatids separate from each other and migrate to opposite ends of the cell" after the division of the centromere.
Answer:
The Thalamus relays sensory signals, regulation of consciousness, sleep and alertness. While the pons of the human brain act as message senders and receivers. It also connects the upper and lower part of the brain.
Explanation:
Answer:
Horizontal
Explanation:
Horizontal gene transfer may be defined as the transfer of the genetic material from the parents to their offspring. Three main methods of horizontal gene transfer are conjugation, transformation and transduction.
The transfer of plasmid among the members of bacterial community mainly occur by the horizontal gene transfer. This transfer of genetic material allows the bacteria to withstand at extreme conditions, confer antiobiotic resistance and increase their chance of survival in the environment.
Thus, the answer is horizontal gene transfer.
