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.

There are no choices, I'll assume that the Nereus in the question refers to the underwater vehicle.
Facts about the Nereus
1) It is an HROV or <span>hybrid unmanned autonomous underwater vehicle. Operated underwater but its operator is in a remote location.
2) Built and operated by WHOI or </span>Woods Hole Oceanographic Institution<span>
3) Designed to explore the deepest surveyed point of the ocean worldwide named Challenger Deep.
4) Deepest dive was at 35,768 feet of the Mariana Trench last May 2009.
5) Was lost on May 10, 2014 after it imploded due to pressure in the Kermadec Trench</span>
Answer:
Ecological footprint estimates the requirements of renewable resources that a population consumes to live a particular lifestyle. Some ecologists are concerned because the result of the ecological footprint shows that the demand of the population is increasing in comparison to the supply of nature.
For example in India, the ecological footprint shows negative impact of population demand over supply of nature.
Answer:
Mitosis involves in cell division.
Explanation:
Mitosis may be defined as a process of cell division which results in the formation of two daughter cells each from a parent cell and each cell having having the same number of chromosomes and chromosomes of the same type as that of the parent nucleus.
The main difference between meiosis and mitosis of a nucleus cell is that it involves only one cell division. And so the cell goes by the steps of prophase, then metaphase, then anaphase and finally telophase. The specialized cells could not survive independently to each other, so they have to develop some complex system of communications like the circulatory system and the nervous system. In this way they can survive. If one of the system dies, entire organisms is more likely to follow.
