The best description of chromosomes by the end of metaphase 2 of meiosis is that they are lined up in the middle of the cell. You can help remember this by thinking of the "M" in metaphase as middle. this is because in this phase the chromosomes are lined up in the middle of the cell.
Answer:
Most likely diagnosis is Basal Cell Carcinoma (BCC), most likely caused by years of prolonged exposure to sunlight over time.
Explanation:
Basal Cell Carcinoma (BCC) is a common type of skin cancer that develops when the basal cells that is responsible for producing new skin cells when they die, become mutated and causes the basal cell to abnormally multiply rapidly and continues to grow. The accumulation of these abnormal cells is what results in cancerous tumors that appears like ulcers on the skin. Prolong and intense exposure to the ultraviolet (UV) radiation from sunlight has been linked to the most likely cause for the mutation of the DNA in the basal cells which leads the abnormal cell growth and multiplication. People who expose themselves to the radiation of the sun for longer periods, over time, are at high risk of developing this cancer.
Answer:
New allele combinations are acted upon by natural selection.
Explanation:
Recombination may be defined as the process of the exchange of the genetic material between the homologous chromosomes of the non sister chromatid. The combined trait will be visible in the upcoming generation.
The recombination allows the generation of the new genes in the population. These new genes if beneficial for the population will be pass to the next generations. The new allele will be favored by the natural selection and increases the chance of survival of the population.
Thus, the correct answer is new allele combinations are acted upon by natural selection.
