Answer:
dichloro-diphenyl-trichloroethane
Explanation:
DDT is an insecticide that can pass up the food chain from insects to small birds, and then from the small birds to birds of prey, like hawks. It can accumulate in the birds of prey, giving them a large amount of DDT
Answer: White blood cells form to fight off cell infections.
Explanation:
1. Your body produces white blood cells which fight against infected cells, depends on what type of cell it is and how infected it is.
2. The immune response to a viral infection is primarily generated by a type of white blood cell called lymphocytes; cells that are mostly localized in ‘lymphoid tissues’ such as the lymph nodes or tonsils. However, the number of lymphocytes that can recognize and react against any individual type of virus is initially very small. This is particularly true for a novel virus such as SARS-CoV-2, which people have never encountered before. In order to produce an effective immune response, the small number of lymphocytes that can recognize a virus must become more abundant. Even though lymphocytes proliferate quickly it still takes several days before there are sufficient cells available to fight back against the infection. During this period the virus may also be spreading rapidly, so there is a race between the virus and the immune system that may determine the final outcome, in terms of recovery.
Answer:
The correct answer is "preservation of wetlands".
Explanation:
Wetland are areas of lands that are saturated with water, usually comprised by marshes or swamps. Preservation of wetlands help to reduce the risk of floods because wetlands temporarily store and slow the release of stormwater. It has been reported that areas where wetland have been lost, the chances of flood increases by as much as 80 percent. The government of a flood-prone region would likely reduce the risk of floods by preserving its wetlands.
Mitosis is a type of cell division for somatic cells and for the asexual reproduction of unicellular eukaryotic cells.
Meiosis is the type of cell division for the production of gametes in sexual reproduction . Meiosis is the process through which egg and sperm cells are formed. Mitosis is a necessary step for life.
A cell copies all of its components, including its chromosomes, and separates to generate two identical daughter cells during mitosis.
Meiosis is a form of cell division that occurs in sexually reproducing organisms and results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm).
Mitosis is the division of a single cell into two identical daughter cells (cell division).
Mitosis is a kind of cell division that occurs in somatic cells as well as in unicellular eukaryotic cells during asexual reproduction. Meiosis is a sort of cell division that occurs during sexual reproduction to produce gametes.
