¿Cómo se le llama a los que pudieron dar origen a los seres vivos actuales?
natta225 [31]

Answer:

Una de las características de los seres vivos se encuentra en su composición biológica, dado que todos ellos están constituidos por cuatro bioelementos esenciales que se encuentran de manera abundante en la naturaleza:

Carbono

Hidrógeno

Oxígeno

Nitrógeno

Estos bioelementos o elementos biogénicos están presentes en las biomoléculas, que son las que dan forma a la materia que constituye a los seres vivos. Estas moléculas están formadas, a su vez, por la unión de átomos.

De estos bioelementos, es importante destacar el papel del hidrógeno y el oxígeno, que dan lugar a la molécula del agua. El agua, o H2O, juega un papel fundamental en el funcionamiento de los seres vivos.

The ratio of estrogen to progesterone remains constant throughout pregnancy into labor. false/true
Lady_Fox [76]

False,

In order to start labor, estrogen increases and progesterone decreases.

Estrogens are a class of hormones that are essential for women's healthy sexual and reproductive development. They are sex hormones as well. The majority of estrogen hormones are produced by a woman's ovaries, however minor quantities are also produced in modest amounts by the adrenal glands and fat cells.

Progesterone is a member of the progestin drug class (female hormones). By lowering the level of estrogen in the uterus, it functions as a component of hormone replacement treatment. By substituting for the natural progesterone that some women lack, it helps to initiate menstruation.
