Oduvanchick [21]

Answer:

There are three types of neurons are present i. e. sensory neuron, motor neurons and inter neurons.

Explanation:

Sensory neurons are the nerve cells which is responsible for sending the information from the sense organs such as tongue, nose, skin, ears, and eyes to the spinal cord and the brain while the motor neurons are responsible for the transportation of instruction from the brain and spinal cord to the muscles. The inter neuron helps in communication between motor or sensory neuron and the nervous system.

What might happen if you try to plant a tree that is native to tropical rainforests in the tundra?
Cloud [144]

Answer:

The tree will not survive due to the nature of the tundra

Explanation:

The tundra comes from a finnish word "tunturia" which means barren or treeless land. It is classified as a cold icy desert with permafrost on the ground. Unlike the tropical rain forest which is a wet climate group and is a forest of tall trees in a region of year round warmth, the tundra is cold and dry. The tundra soils are formed at high altitudes, they are usually frozen. Common plants in tundra are shrubs, herbs, lichens and grass and usually grow in groups and remain closer to the ground for prevention against cold winds. The cold nature of the tundra and its soil prevent the growth of trees because trees need to have deeper roots and they cannot grow on frozen ground.

Si una población crece mucho otra vez después de un cuello de botella con el paso del tiempo aumentará diversidad genética ¿por
sammy [17]

Answer:

los mecanismos capaces de generar diversidad actúan para incrementar la variabilidad genética en la población que sufrió el cuello de botella

Explanation:

Un cuello de botella se refiere a una reducción drástica en el tamaño de una población (por ejemplo, debido a una catástrofe natural). Un cuello de botella es un fenómeno que está asociado a la ​reducción en la variación genética y fijación de ciertos alelos en la población resultante, lo cual es causado por la deriva genética, es decir, debido al muestreo al azar de los individuos que formarán la población en la siguiente generación. Paulatinamente, los mecanismos capaces de generar variabilidad genética aumentarán nuevamente la diversidad de la población que sufrió el cuello de botella. En una población de reproducción sexual, la variación genética se genera mediante cuatro procesos diferentes: 1-mutación (es decir, la aparición de nuevos alelos debido a alteraciones en la secuencia de ADN); 2-recombinación (es decir, el intercambio de información genética entre cromátidas no hermanas durante la meiosis); 3-segregación independiente de cromosomas durante la meiosis (capaz de producir nuevas combinaciones de alelos) y 4-fertilización al azar (lo cual también incrementa el número de combinaciones entre gametos que darán lugar a un nuevo individuo).
