Answer:
Malignant melanoma cells would have active telomerases that constantly replenish and lengthen telomeres.
Explanation:
Telomerase can be described as enzymes which add the repetitive sequences called telomeres at the end of a chromosome. Telomeres can be described as repetitive sequences at the end of the chromosome which are involved in protecting the chromosome from any damage.
In a normal skin cell, the telomeres will shorten with time. But in a malignant skin cell, the telomerase will add the repetitive sequence again and again. The telomers will not be able to shorten.
Answer:
Deserts
Explanation:
Based on the data table, we would expect deserts to have the greatest changes in temperatures during a 24-hour period. There is little water or vegetation containing water in desert areas. The data shows the greatest increase and decrease in temperatures to be in the cups of sand.
In patient-centered care, all healthcare decisions and quality measurements are driven by the individual's specific health needs and desired health outcomes.

Answer:
2 & 4
Explanation:
The theory of spontaneous generation stipulated that life emanated spontaneously from ‘nothing’. This was believed to be true until Francesco Redi & Luis Pasteur later falsified this theory using an experiment. He had two plates of cooked meat. He covered one with a glass bowl and left the other open. The plate with a bowl did not develop maggots while the open one did. This showed that maggot was as a result of hatched eggs that were deposited by flies. Life, therefore, emanates from life.
