Answer:
Los sistemas sensoriales son conjuntos de órganos altamente especializados que permiten a los organismos captar una amplia gama de señales provenientes del medio ambiente. ... Esas señales son transportadas por vías nerviosas específicas (haces de axones) para cada modalidad sensorial hasta los centros nerviosos.
I agree with the other one “The sperm whale has a diploid complement of 2n=42 and the killer whale a complement of 2n=44. These two species, though different in chromosome number, have karyotypes which have no t group chromosomes and more m group chromosomes than the typical whale karyotype.”
No the right answer is A. Homeostasis allows organisms to regulate their temperature because it makes sure the organisms cells do not burst or shrink. This allows the organism to survive.
Answer:
Written below.
Explanation:
5. During meiosis, a reproductive cell and its nucleus divide twice and produce four cells––two pairs of identical haploid cells.
6. Homologous chromosomes are two pieces of DNA within a diploid organism that carry the same genes, one from each parental source. In simpler terms, both of your parents provide a complete genome. Each parent provides the same 23 chromosomes, which encode the same genes.
The alveoli are the sites of gas exchange they are located at the terminal regions of the lung and are attached to the respiratory bronchioles.
Tiny air sacs at the end of the bronchioles (tiny branches of air tubes in the lungs). The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out.
This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli. Gas exchange occurs within the lower airways, primarily the alveoli. Often called the business end of respiration. Blood entering the lungs via the pulmonary artery is deoxygenated. It becomes oxygenated when the capillaries pass through the alveoli and reenters the heart via the pulmonary vein with oxygenated blood.
