Answer:

Explanation:

This statement is incorrect because the Cytoskeleton is not unique to animal cells. Vegetal cells also have a cytoskeleton.

Answer:

The cytoskeleton is a unique structure of all eukaryotic cells, which are all cells that have true nucleus. Thus we can say that the cytoskeleton is present in cells animal, plant cells and any other eukaryotic cell.

Explanation:

The cytoskeleton is a complex network of fibers found in eukaryotic cells that allows them to adopt various shapes and perform the most varied movements. It is composed of three types of molecular structures: the microtubules, the actin microfilaments or filaments and the intermediate filaments.

The cytoskeleton therefore has several functions, which can be summarized as follows:

  • Ensures shape and mechanical support of the cell;
  • Promotes movement of cytoplasmic organelles and vesicles;
  • Important in cellular contraction;
  • Enables amoeboid movements.

Importantly, the cytoskeleton, because it ensures the movement of vesicles and can manipulate the plasma membrane, enables processes such as endocytosis and exocytosis to occur.

The angle bisector theorem is commonly used when the angle bisectors and side lengths are known. It can be used in a calculation or in a proof. An immediate consequence of the theorem is that the angle bisector of the vertex angle of an isosceles triangle will also bisect the opposite side.

What does paleontology, biogeography, embryology, and anatomy reveal bout evolution
Ugo [173]

Paleontology deals with fossils and helps in learning the changes of living organisms in sequence.

Biogeography deals with the distribution of species across the mother earth.

Embryology deals with the study of the similarities and difference that exists in the embryos of different species or organisms.

Anatomy deals with the study of the similarities and difference that exists among different species or organisms.

<u>Explanation: </u>

As an organism dies, the remaining of these organisms will be buried in soil. These are fossils. Paleontology supports evolution with the information that are related to the fossils, footprints etc. With these we can study the evolution of organisms and also the changes they undergo. There are some technologies like radiometric dating that can be used for the determination of these rocks and fossils ages.

Charles Darwin suggested that the evolution of species were form their ancestor. Biogeography supports evolution by explaining about the distribution of different species over the earth. Embryology and Anatomy supports evolution by describing about the similarity and difference in the species of living organisms. Embryology deals with the embryos and anatomy deals with the structure.

Are viruses always fatal?
aalyn [17]

Answer:

No

Explanation:

The short answer is no, but the more complex one is that it depends on the virus. In the case of *****-19, the answer is no, as many people have recovered from  it. But almost any viral infection can lead to sepsis, which is a chain reaction that can trigger inflammation throughout the body and damage multiple organs. This, however, is very rare, though potentially fatal.
