Indica si son verdaderas (V) o falsas (F) las siguientes frases referidas a la famosa hipótesis de Oparin, razona la respuesta.

La atmósfera de la Tierra primigenia era de tipo oxidante, con oxígeno, por ello pudo aparecer la vida. En la primitiva atmósfera reductora y con la energía de los rayos y la luz se formaron las primeras moléculas orgánicas. Se formaron todos los seres vivos a partir de los gases que formaban la atmósfera primitiva. A partir de los gases de la atmósfera primigenia se sintetizaron aminoácidos y otras moléculas orgánicas que dieron lugar a la sopa o caldo primitivo.

- Are living things only the product of their DNA? Why or why'not?
Darina [25.2K]

Answer:

No, since DNA does code for certain traits, others are introduced or changed by the environment. For example, some adaptations are not coded in DNA, such as dying hair. According to the gene, hair is to be black, for example, but it can be changed to look pink. Another example is when a person is first born. When they are, some bacteria enter the system of the baby --- mostly good. Then the baby's gut will be different, and the bacteria in the gut are not coded by the DNA. So, living things are not only the product of DNA, as there are extraneous factors that affect living things as well.

In a humoral or antibody-mediated immune response, specific B cells are stimulated by Helper T cells to help transform into plas
steposvetlana [31]

Answer:

An important feature that B-cells must have in order to become plasma cells and synthesize antibodies is increased rough endoplasmic reticulum in order to have the surface area needed for antibody production (option A).

Explanation:

The transformation of B cells into plasma cells to produce antibodies is a well known function of lymphocytes related to the immune response. This leads to a series of structural transformations in order to performs their function.

The rough endoplasmic reticulum (RER) has the function of contributing to protein synthesis, in conjunction with the ribosomes that are attached to it and the information of the mRNA.

<em>One of the changes experienced by B cells in their transition to plasma cells is the availability of larger RERs, in preparation for antibody synthesis, formed mostly by proteins</em>.
