Mesenchymal stem cells are multipotent stromal cells that can differentiate into a variety of cell types.

Correct Answer: Mesenchymal stem cells
Mesenchymal stem cells are multipotent stromal cells that can separate into an assortment of cell types, including osteoblasts (bone cells), chondrocytes (ligament cells), myocytes (muscle cells) and adipocytes (fat cells which offer ascent to marrow fat tissue).

Which of the following statement(s) is/are CORRECT for antigen activated effector T cells?
P. CD4+ cells make contact with macrophages and stimulate their microbicidal activity.
Q. CD4+ cells make contact with B cells and stimulate them to differentiate into plasma cells.
R. CD8+ cells make contact with B cells and stimulate them to differentiate into plasma cells.
S. CD8+ cells make contact with virus infected cells and kill them.

In tomato plant, red (R) is dominant over yellow (r) for fruit color and purple (P) is dominant over green (p) for stem color. Fruit color and stem color assort independently. The number of progeny plants of different fruit/stem colors obtained from a mating are as follows:
Red fruit, purple stem - 145
Red fruit, green stem - 184
Yellow fruit, purple stem - 66
Yellow fruit, green stem - 47
What are the genotypes of the parent plants in this mating?

With reference to 'stem cells', frequently in the news, which of the following statement(s) is/are correct?
1. Stem cells can be derived from mammals only.
2. Stem cells can be used for screening new drugs.
3. Stem cells can be used for medical therapies.
Select the correct answer:

A solid-oxide fuel cell is fed with carbon monoxide and reacts with air to produce CO2. This reaction will produce 2 electrons which are used to power an electric circuit external to the fuel cell. The reaction equation is shown below: 2CO(g) + O2(g) -> 2CO2(g) ΔHr° = -565.96 kJ/mol This reaction does not occur for other types of fuel cells which use a catalyst, such as polymerelectrolyte membrane or phosphoric-acid fuel cells. The presence of carbon monoxide on the anode side of these types of fuel cells will cause catalyst poisoning, reducing the efficiency and voltage of the fuel cell. Determine the rate of enthalpy change for a carbon dioxide production rate of 208 mol/hr. The extent of the reaction occurring in the fuel cell can be obtained by the following equation: where:

________ refers to the varying ability of stem cells to differentiate into specialized cell types.

The developing tooth bud of the mandibular third molar is a rich source of Mesenchymal Stem Cells.

_________________ is the most frequently utilized source of Mesenchymal stem cells.

Which of the following statements are correct regarding common differences between plant and animal cells?
1. Plant cells have cellulose cell wall, while animal cells lack it.
2. Plant cells lack plasma membrane, while animal cells have it.
3. Mature plant cell have a large vacuole, while animal cells have numerous small vacuoles.

Which of the following cell is a multipotent cell?

Each type of blood cell begins as stem cell called as pluripotent haematopoietic stem cell.
