Answer:

The correct answer would be B. thrombocytes.

Thrombocytes, also called platelets are the components of the blood which play important role in the process of hemostasis.

Hemostasis is the process of preventing the flow of blood from the damaged site or damaged blood vessel. It is the first stage involved in the healing of the wound.

Platelets form the platelet-plug at the site of damage which in turn activates another blood clotting factor fibrinogen.

Fibrinogen gets converted into an active fibrin (insoluble) which forms the meshwork like structure to trap more and more platelets and red blood cells. It results in the formation of a clot which completely seals the cut or damaged site.

yulyashka [42]

Answer:

1) In eukaryotic flagella, the fibers that slide past one another due to the activity of dynein proteins are microtubules.

2) Many cell organelles, most notably the nucleus, are anchored by intermediate filaments which are assembled from a diverse class of proteins.

3) Centrosomes are sites where protein dimers assemble into microtubules.

4) The extension of pseudopodia in amoeba is due to the regulated assembly and destruction of microfilaments.

5) The only cytoskeletal fibers not associated with intracellular movement or whole cell locomotion are the intermediate filaments.

6) During muscle contractions, myosin motor proteins move across tracks of microfilaments.

Explanation:

The cytoskeleton is a very important element of the cell, and is composed of three different structures: microtubules, intermediate filaments, and microfilaments.

<u>Microtubules</u> are structures in the shape of hollow tubes that <u>give shape to the cell</u>. Microtubules also participate in cell motility by <u>providing a route</u> for the organelles to move through.

Intermediate filaments are the only ones that do not participate in cell motility: their main function is to <u>provide mechanical support for the plasma membrane</u>.

Microfilaments are a key component in <u>cell motility</u>, and also associate with myosin (a protein) to produce <u>muscle contraction</u>. Microfilaments also give the cell the ability to grow <u>pseudopods</u>.

Which of the following statements is true of cyclin-dependent kinases? O O O O O They regulate the cell cycle by phosphorylating
jekas [21]

Answer:

They regulate the cell cycle by phosphorylating other proteins

Explanation:

they are serine-threonine kinases, they play an important role in the phosphorylation of other proteins. Cyclin-CDK complexes phosphorylate substrates appropriate for a particular cell cycle phase and without that, the cycle cannot continue.

Which of the following statements is true?
maksim [4K]

Answer:

All organisms require sulfur as a macro-nutrient. (Ans. E)

Explanation:

Sulfur is necessary for all living things. It is taken up in the form of sulfate from the soil and sea water by the plants, and algae.

Sulfur is known as the essential nutrient for plant growth. Sulfur playing various important role in plants. About 90% of the sulfur is absorbed by the plants for the purpose of amino acids synthesis, known as the building blocks of proteins. Sulfur is important for the enzyme which is helping in the formation of the chlorophyll molecule. Sulfur is essential for the synthesis of oil crops.

In human body sulfur playing some essential role such as amino acid production which is converting into proteins and producing enzymes. Sulfur is important for insulin production, insulin allow the cells to use glucose as energy. Sulfur is found in most important antioxidant known as glutathione, which helping in the inhibition of oxidation of the other molecules and preventing from cell damage. Collagen provide skin strength and structure, sulfur is important for collagen synthesis as well.
