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.
Explanation: we will conclude this by the following characteristics:
1.organims that lack a proper nucleus.
2.they have membrane bounded organelles
3.they are tiny single cell oraganisms which cannot be seen by naked eye.
4.they are the oldest livinh organisms on earth
5.they are present in very harsh conditions like volcanic vents or at the bottom of the sea
Answer:
Endothermic
Explanation:
Amphibians are ectothermic organisms. Ectothermic animals are coldblooded animals. From the options above, the correct answer is endothermic because amphibians are not hot blooded and are never endothermic.
Answer: genus
Explanation:
The answer to the question is genus. The genus is where microevolution occurs or happens. The domain, species, kingdom, family, or population are not the taxonomic category where microevolution occurs. The answer to the question is genus.
Have a nice day!
The trenbolone acetate caused frank's testicles to shrink<span> because the steroid is taking over
the job of the testes so the testes don’t have to do as much work making them
less muscular. Trenbolone acts in the same way
that testosterone acts, but the esterified form of the hormone is approximately
3 times more potent than the naturally occurring hormone; that is, 3 times more
testosterone is required to produce the same effects as a particular amount of
trenbolone acetate. </span>Some of
its trade names are Trenbol, ester derivative and synthetic steroid. Its chemical structure is similar
to that of testosterone, the naturally occurring hormone that is produced by
the testicles.
