MaRussiya [10]

Answer:

The correct answer is C: l<em>oss of chloroplasts.</em>

Explanation:

The parasite would lose chloroplasts. As they absorb nutrients from the fish digest food in the gut of the animal, parasites do not need to photosynthesize any more. There are some parasites in the fishes digestive tract that conserve their motile capacity by keeping their flagellum or cilium. Some species get their membranes thicker for protection in their interaction with the host, and they can also secrete a special capsule.  In general, these organisms reproduce asexually.

¿que organismo o institución en el Perú se encarga de estudiar el clima para realizar los perfiles climáticos?
kap26 [50]

El Ministerio de Medio Ambiente (MINAM) gestiona esto, lo gestiona a través del comité nacional sobre el clima.

El cambio climático en Perú es vulnerable y necesita altas adaptaciones. Hay una gran contribución al calentamiento global por el derretimiento de sus glaciares ubicados en los picos andinos.

La pesca y la agricultura en las regiones costeras de bajo nivel son propensas a la elevación de alta mar que puede destruir las infraestructuras económicas y disponibles presentes.

Esta institución de los gobiernos está haciendo un esfuerzo frenético para reducir esta vulnerabilidad, asegurando una reducción en la emisión de gases de efecto invernadero.

Además, el país está adoptando caminos con bajas emisiones de carbono en un intento por conservar la reserva forestal de carbono, con una mayor reducción de las emisiones de la combustión de combustible y otros sectores industriales.

Answer:

The climate change in Peru is vulnerable and needs high adaptations.There is high contribution to global warming from the melting of its glaciers located on at the   Andean peaks.

Fishery and agriculture at low-levels coastal regions are prone to high sea rise which may destroy the  economic and available infrastructures present.

This institution of the governments is making frantic effort to reduces this vulnerability, by ensuring reduction in the green house gas emission.

Besides the country is embracing low carbon paths in an attempt to conserve the forest carbon reserve,with further reduction in emission from fuel combustion and other industrial sectors.

BlackZzzverrR [31]
These hydrogen atoms can come together in nuclear processes called fusion, which is the process that powers the sun, and through fusion, heavier atoms such as carbon and nitrogen are produced. These in turn undergo fusion to make even heavier atoms, and it is such processes that created all the atoms in the earth.
