Answer:

<em>Chlorophyll is a green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis. It's molecule contains a magnesium atom held in a porphyrin ring. The reason that chlorophyll is green is because it absorbs other colors of light such as red and blue, so in a way the green light is reflected out since the pigment does not absorb it. Hope this helps! Have a blessed day!</em>

Chlorophyll is a part of plants that makes food like sugars and starches in order for the plant to survive. The green pigmentation that it has comes from absorbing the red and blue light hues in the surrounding areas to reflect it back as green as blue and red make green.

AysviL [449]

Answer:

The correct option is D, that is, THEIR FUNDAMENTAL NICHE HAS BEEN COMPROMISED.

Explanation:

From the information given in the question, we are told that the expanses of the Great Plains, which was once occupied by the prairie dogs have been reduced in size due to increased housing and agricultural developments. This implies that, the habitat, which is natural to the prairie dogs has been reduced in size, in another word, their fundamental niche has been compromised.

Ears

¿Qué es el oído y qué hace?

El oído consta de tres partes diferentes, que funcionan conjuntamente para captar sonidos y transmitírselos al cerebro: el oído externo, el oído medio y el oído interno.

El oído externo

El oído externo está formado por el pabellón auditivo (también conocido como "pabellón auricular" o "pabellón de la oreja") y el conducto auditivo. Los pabellones auditivos son las partes visibles que tenemos a ambos lados de la cabeza y están compuestos por cartílago duro cubierto de piel. La principal función del pabellón auditivo consiste en captar sonidos y conducirlos hacia el conducto auditivo, que conecta con el oído medio. Las glándulas de la piel que recubren el interior del conducto auditivo fabrican cera o cerumen, que protege este conducto, eliminado la suciedad y ayudando a prevenir posibles infecciones.

El oído medio

El oído medio es una cavidad llena de aire que transforma las ondas sonoras en vibraciones y las transmite al oído interno. El oído medio está separado del externo por el tímpano (o membrana timpánica), una fina lámina de tejido que va de lado a lado del conducto auditivo y que está fuertemente tensada sobre él. Los sonidos golpean el tímpano, haciendo que se mueva.
