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.
The correct option are as follows:
estimating temperature to the nearest tenth of a degree
estimating the mass of the sample to the nearest tenth of a gram
the position of the cups of sand and water under the heat lamp
<u>Explanation:</u>
Error is an uncertainty or the amount of deviation in a physical quantity. There may arise some deviance while measuring physical quantity due to approximation.
Instrumental, environmental, procedural, and human are some of the common sources of error. The error can be classified into two types:
i) Random error
ii) Systematic error
Types of error are determined based on the deviation in the result. While observing the temperature of something, the temperature should be noted to the nearest tenth of a degree. In similar way, the mass of the sample should be estimated to the nearest tenth of a gram.
100% shore its B hope that helps you good luck
Answer:
The correct answer is - drinking more water and fluid.
Explanation:
Hypernatremia is a condition in which the body losses too much water or body fluid and the case of dehydration took place which leads to the low serum sodium concentration. The serum sodium concentration is under 145 mmol/L in this condition.
This occurs due to loss of body fluid due to sweating, diarrhea injury, or drinking very little water. To correct or treat this treatment in a healthy person it is asked to drink plenty of water and other fluids to maintain body fluids.
