Answer:
When the soot vanished, the light-flecked moths started to repopulate. Their numbers increased as the dark peppered moths began to decline.
Explanation:
Once the soot disappeared, the light-colored moths reappeared and their numbers increased. The dark-colored moth population is declining.
What is industrial melanism?Industrial melanism is a type of natural selection. In natural selection, nature selects the fittest individual that can live and reproduce.
Light-coloured moths were originally camouflaged with the light colored bark. Hence, predators couldn't differentiate between the bark and the light moth. Predators feed upon dark moths, as they are clearly visible.
After industrialization, the soot covered the bark, and as a result, the bark turned black. White moths were easily differentiated from the dark bark and fed by predators. The population of light moths declined, and the population of dark moths increased as they gained an advantage due to industrialization.
After the soot vanished, the bark turned light again, giving the light-colored moth an advantage. They could hide from the predator. Dark-colored moth populations again declined as they fed upon predators.
Hence, after the soot disappears, the dark moth population declines and the light moth population increases.

Que neurotransmisor afecta directamente al musculo esquelético: * Acetilcolina Triptófano Adrenalina Serotonina Endorfina
Answer:
Acetilcolina
Explanation:
La acetilcolina es un neurotransmisor excitatorio producido por neuronas del sistema nervioso periférico, es decir, células nerviosas que conectan el sistema nervioso central (SNC) con los diferentes órganos. La unión de acetilcolina a receptores específicos localizados en células del músculo esquelético conocidos como 'receptores nicotínicos' desencadena la contracción del músculo. Los receptores nicotínicos pertenecen a una superfamilia de proteínas de canales iónicos activados a través de la unión a acetilcolina, lo cual desencadena la despolarización de células musculares esqueléticas. Por otra, parte, la acetilcolina también posee un rol inhibitorio en células musculares cardíacas, donde su unión a receptores especifícos llamados 'receptores muscarínicos' disminuye la frecuencia cardíaca.

The atmosphere is full of nitrogen gas (N2). But plants cannot use nitrogen in this form. Summarize the roles of bacteria in making nitrogen available to plants and in returning nitrogen to the atmosphere.
Answer:
Prokaryotes play several roles in the nitrogen cycle. Nitrogen-fixing bacteria in the soil and within the root nodules of some plants convert nitrogen gas in the atmosphere to ammonia. Nitrifying bacteria convert ammonia to nitrites or nitrates.... Denitrifying bacteria converts nitrates back to nitrogen gas.

Answer:

Explain what a karyotype is and
how it can be used to evaluate
the genetic health of an
individual.
Explanation:
Clinical cytogeneticists analyze human karyotypes to detect gross genetic changes—anomalies involving several megabases or more of DNA. Karyotypes can reveal changes in chromosome number associated with aneuploid conditions, such as trisomy 21 (Down syndrome).
Karyotype is a test to identify and evaluate the size, shape, and number of chromosomes in a sample of body cells. Extra or missing chromosomes, or abnormal positions of chromosome pieces, can cause problems with a person's growth, development, and body functions.

Because plants are unable to move as much as animals, on what does their ability to reproduce
depend?
a. Vascular tissue
b. Roots
c. Seeds and spores
d. Leaves
Answer:
Seeds and spores
Explanation:
Plants are unable to move as much as animals, hence their ability to reproduce depends on seeds and spores.
What do you mean by Reproduction?Reproduction may be defined as the process of producing offspring with the help of parental gametes.
Vascular tissues are responsible for the transport of minerals and nutrients throughout the plants, leaves perform the process of photosynthesis, and roots provide mechanical strength to the plants.
Therefore, plants are unable to move as much as animals, hence their ability to reproduce depends on seeds and spores.
