Ans.
Tuberculosis (TB) is a bacterial infection that affects mainly respiratory tract and can be transmitted from one to another person through contaminated air. The causative agent of tuberculosis, <em>Mycobacterium tuberculosis</em> has developed resistance against many antibiotics, such as rifampin and isoniazid, which is known as tuberculosis drug resistance.
If a person infected with TB shows drug resistance against some TB drugs, 'doctors should give other TB drugs to that person, even if these drugs show less effect than common drugs'. This is because these drugs can prevent or kill the bacterium more effectively than the common drugs for which, bacterium is resistance.
Living things consists of the organisms like the plants, animals, fungi, protozoa and bacteria. These animals vary in the complexity of the body and have different number of cells in their body. Organisms like the plants and animals are made up of several different kinds of cells. These organisms are called multi-cellular organisms. On the other hand, organisms like the baker's yeast (a fungi) and a plethora of bacteria are single celled organisms. They are called unicellular organisms. Hence we can say that the living things are made up of at least one cell.
Cytokinesis is the process wherein actual division of the cell, including the cell membrane and the cytoplasm, from the parent cell to two daughter cells. The correct answer in this question is "the metaphase plate is the beginning area for cytokinesis" as the metaphase plate dictates the midpoint of the cell. A cell with a cell wall (plant cell, for example) cannot perform cytokinesis with a cleavage furrow but with a cell plate. Phragmoplast only develops in plant cells. Lastly, cytokinesis only starts after telophase.
CO2 = Carbon + two Oxygen
Glucose= C6H12O6 = six Carbon + twelve Hydrogen + six Oxygen
so the answer is Carbon and Oxygen.
Answer:
Translocation
Explanation:
Changes in chromosome include deletions, duplications, inversions, and translocations.
- Deletion occurs when an end of a chromosome breaks off.
- Duplication is the presence of a chromosome segment more than once in the same chromosome.
- Translocation is when a fragment of chromosomal breakage join a nonhomologous chromosome.
- Reciprocal translocation is a chromosome abnormality caused by exchange of parts between non-homologous chromosomes.
- Robertsonian translocation occurs when two non-homologous chromosomes get attached, meaning that given two healthy pairs of chromosomes, one of each pair "sticks" together.
