Why is genetic variation important?

2 answers:

Um variabilidade genetica é importante para índividuos de certa especie porque permite a estes uma evolução, ou seja, uma persistencia evolutiva dessas especies, e também em relação aos casos de especies que não possuem essa variabilidade genética, a variabilidade das caracteristicas é util, por exemplo, se : -Um certo virus, ou uma certa doença..enfim..atingir um individuo dessa população, isso não signfica que todos serão afetados por esse doença, diferentemente do caso em que individuos que não possuem esta variabilidade(seriam todos mortos por esse virus)

Genetic variation is important because a population has a better chance of surviving and flourishing than a population with limited genetic variation. Genetic diversity also decreases the occurrence of unfavorable inherited traits.

The epiglottis

The cartilage in the throat that guards the entrance to the trachea and prevents fluid and food from entering it when a person swallows is known as the epiglottis .

The epiglottis is an elastic flap located at the upper end of the larynx in the throat. The epiglottis is the valve that turns passage to either the esophagus or the trachea. The epiglottis allows air to enter the airway to the lungs during breathing, and during swallowing, it allows food and fluids to pass into the gastrointestinal tract.

Can you guys tell me these all animals mode of nutrition

marishachu [46]

Answer:

As per my full understanding,

There are two main modes of nutrition:

Autotrophic – Plants exhibit autotrophic nutrition and are called primary producers. Plants synthesis their food by using light, carbon dioxide and water.

Heterotrophic – Both animals and human beings are called heterotrophs, as they depend on plants for their food.

WHEREBY: TERMS IN THIS TWO SETS ARE:

Chemohetrotroph. Gets energy from chemicals and carbon from other sources.

Photohetrotroph. Gets energy from light and carbon from other sources.

Chemoautotroph. Gets energy from chemicals and produces its own carbon.

Photoautotroph. Gets energy from light and produces its own carbon.

Species that are_______species can occur in the same location and are phenotypically different.

jeyben [28]

Answer:

Species that are sympatric species can occur in the same location and are phenotypically different.

Explanation:

Speciation is the evolutionary process by which a population of a species acquires differentiating characteristics that lead it to distinguish itself from the species it formed. Sympatric speciation is a type of speciation that consists of the genetic separation of different populations of the same species that live in the same environment (same geographical location), so that species originate by divergence between individuals, that is, they diversify due to to the appearance of isolation mechanisms these can be genetic, ethological or sexual.
