Answer:
The correct answer is given below:
Explanation:
1. A cleavage furrow or cell plate forms, separating the nuclei - Cytokinesis. During cell division, after division of nucleus, cytoplasm divides by furrow in an animal cells and by cell plate formation in the plant cells.
2. Chromosomes line up at the equator and chromatids are attached to spindle fibres—Metaphase. During metaphase all the chromosomes get arranged on the equatorial plane or the central plane
3. Nuclear membrane and nucleolus reappear- Telophase. The nuclear membrane starts to form around each of the daughter chromosomes and nucleolus also reappears in the daughter nuclei.
4. Genetic material replicates and is joined at the centromere- S-phase of the interphase. Duplication or copying of the DNA occurs in this phase
5. Centromeres divide and single-stranded chromosomes move to the poles- Anaphase. During anaphase, the sister chromatids of each chromosome gets separated and move to the opposite poles.
Answer:
Azidothymidine
Explanation:
Azidothymidine (AZT) is one of the nucleoside analogs that is used in the treatment of AIDS as it inhibits the process of reverse transcription of HIV (Human immunodeficiency virus).
The HIV replicates by making DNA copies of RNA through the process of reverse transcription. The process is driven by enzyme reverse transcriptase. Azidothymidine (AZT) serves to inhibit the activity of reverse transcriptase enzyme and thereby does not allow HIV to reproduce.
Albert, a student researcher, varies the amount of food given to rats in an experiment to measure the effect on their learning behavior. In albert's study, the amount of food given is the independent variable.
An independent variable is under the control of the experimenter. Independent variable does not depend on the other variables involved in the experiment. Since the amount of food is varied, it is not depending on other variables like size of mice, weight, etc.
Answer:
Complex carbohydrates contain longer chains of sugar molecules than simple carbohydrates. The body converts these sugar molecules into glucose, which it uses for energy. As complex carbohydrates have longer chains, they take longer to break down and provide more lasting energy in the body than simple carbohydrates
