Is mitosis involved with two sets of nuclear divisions
Naya [18.7K]

Answer:

NO. Mitosis involves one set of nuclear division and results in two nuclei that are exactly the same as the original. On the other hand, meiosis involves two sets of nuclear divisions.

Explanation:

Mitosis is a type of cell division normally occurring at the sites of growth and development of new tissues and also at sites of repair. It also occurs during asexual reproduction of organisms. Each mitotic cell division is a process that follows distinct phases.

Each mitotic division results in the formation of two daughter cells which are genetically identical to the parent cell, that is they have the same number and type of chromosomes as the parent cell.

During telophase, a nucleolus develops in the nucleus of each daughter cell. The cytoplasm divides in the process called cytokinesis. An invagination develops and finally splits the cell into two daughter cell each with its own nucleus and cytoplasm.

A surgeon is in the operating room assisting on a lung transplant he is working at the cellular level
Ronch [10]
The statement above is FALSE. In the scenario given above the doctor is working at the organ level. This is because, he is working with lung which is an organ that participates in breathing. The lung is an organ because it is made up of different tissues which are in turn made up of different cells. 
Working at the cellular level involve working with cells. For instance, when a microbiologist is growing a cell in a culture, he is working at a cellular level.

Succinate dehydrogenase catalyzes the conversion of succinate to fumarate. The reaction is inhibited by malonic acid, which rese
natima [27]

Answer:

C. Succinate is the substrate, and fumarate is the product.

Explanation:

Succinate is the substrate of the enzyme Succinate dehydrogenase, and as a product is obtained fumarate.  In this scenario, malonic acid plays the role of a competitive inhibitor because its structure resembles the succinate's, so they compete for the active site of the enzyme.  So,  A option is wrong because fumarate is not the product. B option is wrong too because malonic acid is an inhibitor, not the substrate.  Also, D is incorrect because malonic acid is a COMPETITIVE inhibitor, not a noncompetitive one. Finally, E can´t be true because malonic acid is not product and fumarate is the product, not an inhibitor.
