All eukaryotic cells have a.

Biology
1 answer:
zaharov [31]3 years ago
5 0

Answer:

All eukaryotic cells have a membrane that covers them, internal fluid and a central nucleus, so the correct answer is option d (All of the above).

Explanation:

Eukaryotic cells are those that possess a plasma membrane that surrounds them, acting as a semi-permeable membrane to the passage of substances, in addition to possessing the capacity to receive external signals.

The cytoplasmic membrane of eukaryotic cells is related to an endomembrane system, associated to cytoplasmic organelles and to the central nucleus, which stores genetic information, in the form of DNA.

The eukaryotic cell cytoplasm is fluid and serves as a support for the organelles, as well as all the chemicals suspended in it.

<u>The existence of true nucleus and organelles is what defines a eukaryotic cell and differentiates them from prokaryotic cells</u>.

Thepotemich [5.8K]
An animal body plan that is triploblastic and coelomate has three main layers of tissue during development.
<span>The germ layers are tissue layers which develop early in embryonic life, through the process of gastrulation. During gastrulation, a hollow cluster of cells-blastula reorganizes into two primary germ layers: an inner layer- endoderm, and an outer layer, - ectoderm which interact to produce a third germ layer - mesoderm. Together, the three germ layers will give rise to every organ in the body. For example, ectoderm will form skin, endoderm will form digestive tract and mesoderm will be involved in the formation of visceral organs like the stomach.</span>

Why would a mutation in a somatic cell of a multicellular organism escape detection?
Mashcka [7]

When a somatic cell is mutated, none of the other cells in the organism mutate with it. Screenings usually detect mutations that are in numerous cells and not in just one. That is why a mutation in a somatic cell of a multicellular organism escape detection.

<h3>What are mutations?</h3>

A mutation in biology is an adjustment to the nucleic acid sequence of an organism's, virus's, or extrachromosomal DNA. DNA or RNA can be found in the viral genome. Errors in DNA replication, viral replication, mitosis, meiosis, or other types of DNA damage (such as pyrimidine dimers from exposure to ultraviolet radiation) can result in mutations.

These errors can then lead to error-prone repairs, particularly microhomology-mediated end joining, error-causing repairs, or errors during replication. Due to mobile genetic elements, mutations can also result from the insertion or deletion of DNA segment.

zheka24 [161]

An ecosystem is a geographic area where plants, animals, and the other organisms work for the existence of bubble life.

<h3>Variation of ecological habitats within a species is characteristic of which type of diversity?</h3>

The variation of ecological habitats within a specie is character of the type of diversity is known as Ecosystem Diversity.

Ecosystem is defined as the different kinds of habitats, ecological processes and communities. A biological community is defined by the specie which occupy a specific area and the interactions between the species.

So we can conclude that: An ecosystem is a geographic area where plants, animals, and the other organisms work for the existence of bubble life.
