Answer:

H. prophase I → genetic recombination events take place

C. metaphase I → aligning of bivalents in the center of a spindle

B. anaphase I → separation of homologous chromosomes

F. telophase I → one haploid set of replicated chromosomes at each spindle pole

D. prophase II → shortest stage

G. metaphase II → aligning of monovalents in the center of a spindle

E. anaphase II → separation of sister chromatids

A. telophase II → one haploid set of unreplicated chromosomes at each spindle pole

Explanation:

Through the process of Meiosis, a diploid germ cell (2n) divides and originates four daughter cells with a haploid chromosome number (n). Each daughter cell has half of the chromosomes of the original one. Meiosis is completed in two phases. During the first phase, and after replication, occurs the chromosome´s reduction division. During the second phase, the cell suffers a new, not reductive division.

1. In the first phase, Meiosis I:

  • Prophase I: Chromosomes condensate and became visible. Occurs crossing-over between homologous chromosomes. Crossin-over makes the daughter cells to be genetically different from the original one.
  • Metaphase I: The pairs of homologous chromosomes randomly align in the equatorial plane.
  • Anaphase I: occurs the independent separation of homologous chromosomes that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells.
  • Telophase I: Each of the homologous pairs chromosomes is already in the corresponding poles, and the nuclear membrane forms again in each pole.

2. In the second phase, Meiosis II:

  • Prophase II: Chromosomes condensate again and become visible.
  • Metaphase II: Chromosomes join the spindle apparatus and migrate to the equatorial plane, where they randomly line up. Sister chromatids are holden together until they reach the Anaphase.
  • Anaphase II: Centromeres divide, chromatids get separated, and each of them goes forward an opposite cellular pole.
  • Telophase II: Once in the poles, the chromosomes became lax again, and cytokinesis occurs.

Receptors for ________, peptide hormones, and eicosanoids are found in the cell membranes of target cells.
Vsevolod [243]
The answer is Catecholamine. It is any of a class of aromatic amines that includes a number of neurotransmitters such as epinephrine and dopamine. The adrenergic receptors are a class of G protein-coupled receptors that are targets of the catecholamines, especially norepinephrine (noradrenaline) and epinephrine (adrenaline). These three - catecholamine, peptide hormones and eicosanoids acts as extracellular membrane receptors which means that these receptors are embedded in the membranes of cells. They act in cell signaling by receiving (binding to) extracellular molecules.

What do we call an organism that is not native to an environment, but is able to thrive anyway?
love history [14]

Answer:

An invasive species

Explanation:

Invasive species come from other environments, many times on accident, but usually thrive so much that they end up taking over and starving other native creatures by taking the resources. Hope this helps! (Brainliest appreciated :))
