Answer:
Cancer and Arthritis
Explanation:
Some causes of cancer include smoking, obesity, and lack of nutrition. Cancer is diagnosed using a biopsy. A biopsy is a procedure in which the doctor removes a sample of tissue. A pathologist looks at the tissue under a microscope and runs other tests to see if the tissue is cancer. Some treatments for cancer include Chemotherapy, surgery, Radiation therapy, and bone marrow transplant.
The most common cause of arthritis is usually if your family has a history of arhritis. It is usually diagnosed with an x-ray or a blood test. Treatment includes Painkillers, physical therapy, and exercise.
Answer:
The process of gene flow
Explanation:
Gene flow refers to the transference of genetic variation from one population to another. High rates of gene flow are known to modify the allele frequencies and reduce genetic differences among groups. Gene flow limits the process of speciation by combining gene pools form different groups. In humans, for example, it has been shown that migration in the past decreased genetic variation among their populations, thereby leading to the homogenization of genotype frequencies among geographic groups. It is for that reason that in population genetics the concept of 'human races' is now often recognized as erroneous and inadequate.
Answer: cytokinesis
Explanation:
In animal cells, cytokinesis is achieved when a contractile ring of the cell microtubules form a cleavage furrow that divides the cell membrane into half.
Answer:
Sinkholes can occur when<u> excessive water use lowers a water table and weakens the substrate.</u>
Explanation:
There are various causes for sinkholes, but all are related to water and how this can affect the soil. One of the causes of sinkholes is the excessive use of water. Excessive use lowers the volume of water in aquifers. As a consequence, the substrates that are above the aquifer change. They can not support large amounts of weight, leading to a sinkhole and soil with low permeability.
