Answer:
La diferencia principal entre células eucariotas y procariotas es que las células eucariotas tienen un núcleo . El núcleo es donde las células almacenan su ADN , que es su material genético. ... Las células procariotas no tienen un núcleo. En cambio, su ADN flota al interior de la célula.
because there is more diversity in ocean ecosystems than land ones
Answer:
Option A
Explanation:
In this case, there are two varieties of horses: Domestic horses that are raised and bred by humans and Wild horses that lives in the wild. The issue of varieties in coat colour of domestic horses can be explained as what occured by selective breeding, also known as artificial selection which is a technique by which humans develop new offsprings with desirable and suitable characteristics. These breeders select two parents that possess beneficial phenotypic traits to mate, producing offsprings with those desired traits such as strength and also for coat colour as stated.
Answer:
The type of evidence is<u> Mechanical incompatibility.</u>
Explanation:
Copulation is often impossible between different animal species because of the incompatible shape and size of the genitalia.It is called mechanical incompatibility.
This isolation prevents species that diverge from interbreeding thus they lo longer able to mate with each other.
Here morphological difference takes place which ultimately leads to behavioral isolation and thus no mating takes place.
Here snail can not mate because their morphological structures are incompatible.
Answer:
Cell membrane/plasma membrane;
Nucleus;
Cytoplasm
Explanation:
Makena's model is synonymous with that of an animal cell.
The soft flexible putter layer of the egg can be likened to the cell membrane of an animal cell. Cell membrane, also called plasma membrane, just like the soft and flexible exterior of the egg, is a semi-permeable that serves as a barrier between the external environment of the cell and it's inner environment. It controls what goes in and out of the cell, as well as help in the selectively exchange of ions and molecules, in and out of the cell.
The yolk in Makena's model represents the nucleus of an animal cell.
Also, the surrounding area between the yolk and the exterior of the egg, represents the cytoplasm found in animal cells. The cytoplasm is filled with fluids and surrounds the nucleus.
