¿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.

DNA Polymerase helps copy a DNA molecule during the process of what?
PtichkaEL [24]
The DNA polymerases are enzymes that create DNA molecules by assembling nucleotides, the building blocks of DNA. These enzymes are essential to DNA replication and usually work in pairs to create two identical DNA strands from one original DNA molecule. During this process, DNA polymerase “reads” the existing DNA strands to create two new strands that match the existing ones.

Every time a cell divides, DNA polymerase is required to help duplicate the cell’s DNA, so that a copy of the original DNA molecule can be passed to each of the daughter cells. In this way, genetic information is transmitted from generation to generation.

Before replication can take place, an enzyme called helicase unwinds the DNA molecule from its tightly woven form. This opens up or “unzips” the double stranded DNA to give two single strands of DNA that can be used as templates for replication.

DNA polymerase adds new free nucleotides to the 3’ end of the newly-forming strand, elongating it in a 5’ to 3’ direction. However, DNA polymerase cannot begin the formation of this new chain on its own and can only add nucleotides to a pre-existing 3'-OH group. A primer is therefore needed, at which nucleotides can be added. Primers are usually composed of RNA and DNA bases and the first two bases are always RNA. These primers are made by another enzyme called primase.

Although the function of DNA polymerase is highly accurate, a mistake is made for about one in every billion base pairs copied. The DNA is therefore “proofread” by DNA polymerase after it has been copied so that misplaced base pairs can be corrected. This preserves the integrity of the original DNA strand that is passed onto the daughter cells.

Structure of DNA polymerase

The structure of DNA polymerase is highly conserved, meaning their catalytic subunits vary very little from one species to another, irrespective of how their domains are structured. This highly conserved structure usually indicates that the cellular functions they perform are crucial and irreplaceable and therefore require rigid maintenance to ensure their evolutionary advantage.

Why do cells use fat and starch for long term energy storage instead of atp molecules
Alex777 [14]

Answer:

because it is hard to breakdown fat in a very short time while ATP can be broken down in a very short time.Fats have a very strong bond of molecular chains and this makes it hard to breakdown quickly
