Answer:
B because homozygous is the alleles in the genotype
Explanation:
First, he should measure how long it takes for the liquid to become clear if X and Y are mixed together. Then, he should measure how long it takes if he also adds substance A to X and Y. He will find out if substance A is a catalyst. hope this helps :)
Answer:
Chromosome condenses
Pairing up to form tetrad
Crossing over
Lining up on metaphase plate
Homologous chromosome separate
Explanation:
Condensation of chromosomes occurs in prophase I phase. Pairing up to form tetrad occur during prophase I. Crossing over occurs during prophase I of meiosis cell division. Chromosomes line up along the metaphase plate in the stage of Metaphase. Centromeres break down and homologous chromosomes separate in anaphase I phase of meiosis.
B I think(sorry if you get this wrong)
Answer:
Answer No 3: Recent studies and researches have shown that the muscle cells do not actually wear and tear during heavy exercises. What happens is that micro tears are formed in the muscle fibers as a result of heavy exercise. These micro tears cause the muscle cells to rebuild themselves.
Answer No 4: One of the biggest reasons that the insertions done by CRISPR-Cas9 insertion would not pass to future generations is because the specialized cells are being modified in this system. As the specialized cells do not have the tendency to for all cells of the body hence, the insertion made by CRISPR-Cas9 will most likely not be transferred to the future generation.
