What are the similarities between an onion and whitefish cells?
Zepler [3.9K]
<span>The similarities between an onion and whitefish cells exist in the cell division process. Normally the basic process of mitosis cell division is similar for plant cells and animal cells, but there are fundamental differences that mark the mitosis of plant and animal cells. Basic similarities of onion cell and that of whitefish embryo cell is that in the four phase of mitosis namely, Prophase, Metaphase, Anaphase and Telophase occurs in similar way. In Prophase for both cells the chromatin condensed and in metaphase the chromatin aligns in the center of cell and kinetochores of chromosomes attached with the microtubules of spindle from opposite poles. In Anaphase stage, the chromatids from the metaphase plate are separated and shifted to opposite poles.. Finally at Telophase, the cell divides via cytokinesis. The fundamental difference between Onion cells and Whitefish cells can be found in the process of cytokinesis.

Which of the following structures is NOT a part of the respiratory system?
ValentinkaMS [17]

Answer:

Uvula.

Explanation:

Respiration may be defined as the process of exchange of gases between the body tissue, lungs and the environment. Oxygen is inhaled and carbon dioxide is exhaled out during the process of respiration.

The choanae, external nares, epiglottis and mouth plays an important role in respiration. Uvula is mainly involved in the production of the salivary gland. The uvula moistens the area and also involved in the speech process. Hence, uvula do not play important role in respiration.

Thus, the correct answer is option (b).

Name a protein structure
umka21 [38]

Answer:

<em>Hello! Deku here!! ^^</em>

Explanation:

Protein structure is the three-dimensional arrangement of atoms in an amino acid-chain molecule. Proteins are polymers – specifically polypeptides – formed from sequences of amino acids, the monomers of the polymer. A single amino acid monomer may also be called a residue indicating a repeating unit of a polymer. Proteins form by amino acids undergoing condensation reactions, in which the amino acids lose one water molecule per reaction in order to attach to one another with a peptide bond.

<em>hope this helps! <3</em>

4. Explain the basic parts of a major theme in molecular biology: the pathway of DNA to RNA to proteins. Include a general idea
Oksana_A [137]

Central Dogma is the molecular process of multiple steps that helps to maintain homeostasis in the cell. The basic parts of protein synthesis are transcription and translation.

<h2>Central Dogma:</h2>

It is the molecular process of multiple steps that helps to maintain homeostasis in the cell.

This includes,

<h3>Replication: </h3>

Formation of new DNA molecules from DNA strands with help of DNA polymerase.

<h3>Transcription: </h3>

It is the process by which RNA is produced by the help of RNA polymerase.

<h3>Translation: </h3>

It is the process of protein formation with help of RNA strands and ribosomes.

Therefore, the basic parts of protein synthesis are transcription and translation.
