Which one of the four RSVP characteristics is most obviously compromised when we ask students to complete an assessment activity
vitfil [10]

Answer:

<h3>Standardization.</h3>

Explanation:

Standardization is one the four RSVP characteristics which uses similar assessing format and procedure for every individual in the same manner.

For instance, if a test was to be conducted for a class, the assessing format should be equal for all. Each and every student should be administered and scored in the same manner.

This form of assessment is done with similar directions, goals, time limit, constraints, etc. Therefore, when we ask students to complete an assessment activity at home in the evening, we are using the RSVP characteristic of standardization.

Daughter cells from meiosis can have a mixture of paternal and maternal chromosomes due to
love history [14]

Answer:

Non-random alignment of chromosome pairs.

Explanation:

Meiosis is when the mother cell or the diploid cell replicates into four haploid cells and divides twice; leaving just two haploid cells that contains only half the number of chromosomes.

Through meiosis, we get the gametes which are the cells that we use to fecund and reproduce ourselves (ovules and sperm); each cell contains half the chromosome content. To allow the combination of genetic information by cross-linking the chromosomes there need to be 23 chromosomes from the father and 23 from the mother to form one individual with 46 chromosomes.

Leaving us with non-random alignment of chromosome pairs as if it was random that would mean that it wouldn’t matter how many chromosomes each parent provides, also, the cells have to be haploid in order to continue the process.
