Answer:
The answer is XX.
Explanation:
Let us say that X is the dominant gene and x is the recessive gene for the height of the pea plants. Pea plants need to be homozygous or heterozygous to have the short phenotype which means it needs to have the genotype xx or Xx.
The F2 offspring has a ratio of 74,5% tall plants and 25,5% short plants. For these results, the stem height pea plant needs to be homozygous which is an XX genotype for the tall pea plant.

Answer:
It wouldn't be able to migrate to the cell's poles.
Explanation:
During anaphase, microtubules attach the chromosome's centromeres and start dragging them towards the poles of the cell. In mitosis, this causes the separation of both sister chromatids for each chromosome, and each chromatid migrates to a different pole. In meiosis, first each homologous chromosome is separated by the same process, and then the sister chromatids are separated during anaphase II. If a chromosome doesn't have centromeres, microtubules are unable to attach the chromosomes, and so the separation of either sister chromatids or homologous chromosomes can't take place.
Answer:
Answer is D, Heart rate monitor.
Explanation:
It is known to be true that during exercise, the rate of the heart beat increases, and this is good for our heart to keep on functioning properly.
A heart rate monitor is usually a chest strap device to measure and sometimes record the rate of the heart's activities such as rate and rhythm. This device is with electrode sensors for transmitting heart rate to an app. Example of a heart rate monitor is Holter monitor.
