Which best explains the role of chlorophyll in photosynthesis?
Tasya [4]

Answer:

B. absorbs energy from the Sun

Explanation:

This is what Chlorophyll does. Chlorophyl's main job is to collect the energy from the sun, and then, it can help the plant make the glucose (plant food).

Look at picture for more explanation. (with picture explanation coming below Extra info)

Extra info:

I learned in my class, that Chlorophyll is on the top most layers under the epidermis and dermis of the leave's skin. There is first the Epidermis, then there are lots and ltos of chloroplast cells, then there are chlorophyll cells in it.

With Picture explanation:

1st image:

The first image shows the leaf's structure. First, you can see the epidermis (on the top), then you can see all those light green round-edged-boxes, those are all the chloroplast cells, then, inside them, are darker green cells, they are the chlorophyl cells.

2nd image:

The second image shows the structure of a chloroplast cell.

The giant light green part on the outside is the chloroplast, then inside that, there are green things, which are the chloroplast, (here they are called thylakoid, because that's the scientific word for it). And then, the other things shown are just extra info.

¿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.

How can I use MIE scattering to determine the best particle size to light scattering with glasses?
Gwar [14]

Answer:

There is a simple algebraic formula relating turbidity to optical properties. You do not need Mie theory. It is given in van de Hulst "Light scattering from small particles" (a nice cheap reprint from Dover Press). More easily accessible are any of the Mie calculators avaiable on the Internet, say Miecalc, these will give the exact result.

Check all of the following which could describe the first interaction of the acquired immune system to an infection. A. Binding
PilotLPTM [1.2K]
<span>E. Stimulation of T-cell by APC</span>

The initial exposure of the body to an infectious agent e.g. through a vaccine, triggers an immune response most of which rapidly diminishes after the vaccination.  However some cells of the immune system called lymphocytes remain with a memory of that pathogen.As a result, if the same pathogen infects a vaccinated person, the memory cells remember and recognize it and rapidly spring into action triggering a much more rapid response specific to that pathogen than the initial exposure, effectively dealing and neutralizing the pathogen.

If a single base pair gets damaged and goes missing from an rna, what would most likely happen?
Vilka [71]

A frame-shift mutation would occur. This is because a deletion will cause a change in codon sequence from the point of mutation to the end of the mRNA.  If the mutation is closer to the start of the mRNA, the larger the effect of the mutation on the translated protein.
