Answer:
Its people would leave and migrate to other locations
Explanation:
Those areas where amount of precipitation having less than 8 inches, these areas are the arid regions. In these areas, water is present in very low amount which is not sufficient for the needs of high population. Minimum agricultural should be done because planting and growing of crops need a lot of water so most of the people migrate to other regions where water is present in large amount.
Answer:
on-native species can become such a common part of an environment, culture, and even diet that little thought is given to their geographic origin. For example, soybeans, kiwi fruit, wheat, honey bees, and all livestock except the American bison and the turkey are non-native species to North America.
Explanation:
Answer:
1.) spindle fibers and centrioles form
2.) chromosomes align on metaphase plate
3.) chromosomes move to opposite poles
4.) two identical nucleotides form
Mitosis is important because it is responsible for the growth of is responsible for human development.
Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.
Explanation:
Answer:
All the given statements are correct except b.
Antimicrobial resistance (AMR) refers to the ability of a microorganism to grow in the presence of drug or a chemical that would normally limit its growth or kill it.
It makes it difficult for the existing drugs to eliminate the infection as they become less effective against the microbe.
There are five major mechanisms by which a microbe attains resistance against antimicrobial chemical or drug:
- Drug modification or inactivation: A microbial enzyme inactivates the antimicrobial agent. For example, few bacteria produce β-lactamases which provide multi-resistance against β-lactam antibiotics such as penicillin, cephalosporin etc.
- Alteration or modification of target site: An altered target site prevents the antimicrobial agent from binding to its target. For example, alteration of penicillin binding protein (PBP) in Methicillin-resistant <em>Staphylococcus aureus </em>(MRSA).
- Alteration of metabolic pathway: The microbe uses an alternative pathway to circumvent the blocked pathway. For example, sulfonamides-resistant bacteria started using preformed folic acid in place of para-aminobenzoic acid (PABA).
- Decreased drug accumulation: Microbial efflux pumps remove the antimicrobial agent (before it could do any damage) by pumping it out of the cell.
- Decrease in cell permeability: The permeability of the microbial envelope to the antimicrobial agent is decreased
The Palestine Liberation Organization (PLO; Arabic: منظمة التحرير الفلسطينية, Munaẓẓamat at-Taḥrīr al-Filasṭīniyyah) is a Palestinian nationalist political and militant organization founded in 1964 with the initial purpose of establishing Arab unity and statehood over the territory of former Mandatory Palestine, in opposition to the State of Israel.
