Answer:
Cyclin-regulates the timing of the cell cycle. Normally, when cells touch, they stop growing. Growth factors-one of a group of external regulatory proteins that stimulate the growth and division of cells.

Answer:
Explanation:
A diploid cell becomes haploid during Meiosis I and is completed after Telephase I. These homologous chromosomes (from mom & dad, all duplicated) pair up during prophase I forming tetrads. The pairs of homologs line up on the metaphase plate during metaphase I
At what stage of meiosis are cells haploid?
Prophase II: Starting cells are the haploid cells made in meiosis I. Chromosomes condense. Metaphase II: Chromosomes line up at the metaphase plate. Anaphase II: Sister chromatids separate to opposite ends of the cell. Telophase II: Newly forming gametes are haploid, and each chromosome now has just one chromatid
If a restriction site is altered, a higher molecular weight band will be observed.
Restriction enzymes are proteins synthesized by bacteria to protect itself against foreign DNA. These enzymes cut DNA at specific places.
This enzyme is used to detect mutations in the genome, particularly those at the sites of action of these restriction enzymes. A healthy subject is compared with the patient who is supposed to have cystic fibrosis. If their DNA migration is different, it means that their DNA is different and that there is a mutation at the restriction sites.
Answer:
These iguanas will go through the speciation process.
Explanation:
Like these iguanas, they were the only ones of their species that managed to reach this island, they will begin to undergo a process of adaptation to the island's environment, which will promote the evolution of their organisms. This evolution will trigger anatomical and even molecular differences that will modify the iguanas, to the point that they can no longer be recognized by the species they represented. Thus generating a new species.
Answer:
amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. For a longitudinal wave, such as a sound wave, amplitude is measured by the maximum displacement of a particle from its position of equilibrium
