Answer:
Mendel choose pea plant (Pisum sativum) for his experiment due to following reasons:
(i) availability of contrasting traits of several characters.
(ii) Their life span is short.
(iii) Normally self-pollination occurs but cross-pollination can also be done by artificial means.
(iv) Large no of seeds produced.
Answer:
The answer to what People with central-body obesity are more likely to develop type 2 diabetes due to increased level of restinin and adipokines.
Explanation:
Type 2 diabetes, which is a disease that is due to resistance to insulin, lack of insulin or high blood sugar is associated with people with intra-abdominal fat because the fat start to partake in hormonal functions in the body which lead to the production of adipokines cause insulin resistance. This is however evident in a high level obesity, which increases serum resistin levels that also contribute to type 2 diabetes called diabetes mellitus.
Answer:
Once a vital plant that many humans or animals need go extinct, many of them will die due to starvation and or shelters they build might not be able to be built due to the extinct plant being gone. As an example, If trees went extinct, humans wouldn't be able to live. One, because trees help filter the air for us humans to breath, wood is a very vital supply too. Wood is used for paper, homes, and even appliances.
Explanation:
Answer:
Air pollution can significantly hurt the quality of soil and water resources. When we pollute our air, we are also polluting the precipitation that falls into water bodies and soils.
Proto-oncogenes signal cells to grow and differentiate. However, they can become oncogenes due to mutations which result in the uncontrollable division of the cells, i.e. cancer. One way is a point mutation in a proto-oncogene. The consequence is changed protein product. Another way is gene amplification of DNA segment containing a proto-oncogene. As the result, the encoded protein is overexpressed. The third way is translocation. As the result of translocation, proto-oncogene can be controlled by the different promoter and expressed inappropriately.
