Answer:
No existe una medida única, existe un conjunto de medidas que pueden reducir la propagación de un virus.
Explanation:
Existe una diversidad de virus diferentes con sistemas complejos que pueden causar diferentes tipos de infecciones en humanos. Hay virus que se propagan por el aire, a través de las secreciones, con tasas de infección más altas o más bajas.
Por tanto, la mejor solución para un virus que impacta en la salud de las personas, como en la situación mundial actual, la mejor solución para la contención de un virus es seguir todas las normas sanitarias informadas por las autoridades competentes y preservarse en el de la mejor manera posible, lavándose evitando circular en ambientes cerrados y manteniendo la distancia social.
The correct answer is (a)
Chlorophyll is contained within the thylakoid membrane. Stroma is the space between the thylakoid membrane and the chloroplast membrane. The outer most part is the double membrane in which the whole chloroplast is housed. It is like the walls of the house.
Chloroplasts are surrounded by this double membrane and contain a third inner membrane which is the thylakoid membrane. This membrane forms long folds within the organelle. In electron micrographs, thylakoid membranes appear like stacks of coins.
Q1. The main difference between flagella and pili in a prokaryotic cell is their length. Flagella are long and thin, whip-like appendages that extend from the interior of the prokaryotic cell. There are much fewer flagella than pili on the prokaryotic cell. Pili are short and hallow, hair-like appendages from the surface of the cell. They do not extend from the interior of the cell.
Flagella are made of protein flagellin while pili are made of protein pilin.
Flagella can be found in both Gram+ and Gram- bacteria while pili can be found only in Gram- bacteria.
A function of flagella is motility. Pili can perform motility but are rather responsible for attachment and genetic exchange.
Q2. Photoautotrophic organisms contain pigments that help them absorb the light of certain wavelength so they can make their own food (because they are autotrophs) in the process of photosynthesis. There are different types of pigments and it is hard to say if they are similar to chlorophyll or not. Because they do the same function, but also they differ in chemical composition.
