Answer:

exposure to ultraviolet radiation is a correct answer.

Explanation:

Ultraviolet light exposure results in the formation of pyrimidine dimers. Ultraviolet radiation damage the DNA by resulting in chemical changes.

Ultraviolet radiation is absorbed by the pyrimidine bases( cytosine and thymine in DNA) and result in the formation of covalent bonds between the succeeding bases.

The formation of the pyrimidine dimers results in the distortions of DNA helix and disrupt the base-pairing during the replication of DNA which results in a mutation.

¿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:

This is being managed by the ministry of environment(MINAM).It manages this through the national committee on climate.

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.

What will cause a decrease in market equilibrium price and an increase in equilibrium quantity? - an increase in supply - an inc
Fudgin [204]

Answer:

- an increase in supply

Explanation:

The interaction between the quantity demanded and the quantity supplied determines the price and the equilibrium quantity in a market economy. This is due to the rationality criteria of the economic agents (consumers will buy more quantities at the lowest possible price) and the law of supply and demand, according to which the excess / lack of products causes price decrease / increase and also an increase / decrease in quantity demanded. Thus, in order for the equilibrium price to decrease and the equilibrium quantity to increase, there must be an increase in supply, as there will be more products on the market, which will cause the price to fall. After the price drops, consumers will demand more. In this way, new price and quantity balance parameters will be determined.
