An animal can respond in negative ways such as: biting, scratching, urinating, whining, restlessness, snippy, or getting sick.
Answer:Un estudio de la Universidad de Barelona demuestra, por primera vez, cómo pueden separarse los genes a lo largo de los linajes evolutivos mediante el mecanismo de la retrotransposición, que es la síntesis de ADN a partir de ARN a través de la transcriptasa inversa.
Explanation:
Answer: Mitosis is a type of cell division in which one cell (the mother) divides to produce two new cells (the daughters) that are genetically identical to itself. In the context of the cell cycle, mitosis is the part of the division process in which the DNA of the cell's nucleus is split into two equal sets of chromosomes.
The great majority of the cell divisions that happen in your body involve mitosis. During development and growth, mitosis populates an organism’s body with cells, and throughout an organism’s life, it replaces old, worn-out cells with new ones. For single-celled eukaryotes like yeast, mitotic divisions are actually a form of reproduction, adding new individuals to the population.
In all of these cases, the “goal” of mitosis is to make sure that each daughter cell gets a perfect, full set of chromosomes. Cells with too few or too many chromosomes usually don’t function well: they may not survive, or they may even cause cancer. So, when cells undergo mitosis, they don’t just divide their DNA at random and toss it into piles for the two daughter cells. Instead, they split up their duplicated chromosomes in a carefully organized series of steps.
Answer:
1) Break down of the nuclear membrane allowing mitotic spindles to connect to kinetochores:A. Metaphase
2)APC degrades securin which allows separase to become active which degrades the cohesin rings: E. Anaphase
3) Dephosphorylation of nuclear pore and lamins: F.Telophase
4) cleavage of plasma membrane by actin and myosin contractile ring:D.Cytokinesis
5) copying of the genome:C. Interphase
6) formation of the metaphase plate:B. Prometaphase
