Explain the difference between chromosomes, chromatids and chromatin. (3-4 sentences)
Drupady [299]

In eukaryotes, DNA is found in chromosomes in the nucleus. Chromosomes are made of a single molecule of DNA and proteins. Chromosomes are linear, and DNA in them is double stranded. There are many chromosomes in a single nucleus. In prokaryotes, a single DNA molecule which is double stranded forms the chromosome. There are no proteins in the chromosome. In viruses, the genetic material is either DNA or RNA. They may be double stranded or single stranded. It may be circular or linear.

Question 22 (Essay Worth 3 points) (02.01 HC) A prediction of the theory of Plate Tectonics is that new volcanoes can form at th
Darina [25.2K]

Answer:

What would be the expected result of the experiment?

For the drawing of the map part, the scientific will find that effectively, a very large number of volcanoes are located near the meeting points of tectonic plates. The volcanoes that aren't now at the edge of the plate were most probably at the moment of their formation, and were moved away by the movement of the plate.

But I doubt the scientist would be able to identify many new volcanoes, because the creation of a volcano isn't something happening overnight.

How would you interpret the results if the scientist observes no new volcanic activity?

I would say that does NOT invalidate the theory because the observation period is extremely short.  10 years is an insignificant amount of time geologically speaking... the study would have to be conducted over at least 1,000 years to maybe have some results at all.   Just imagine how many volcanoes there would be if a new one was created every 10 years along the side of a tectonic plate.

If a person moved from boston to miami, how would the normal pattern of adh secretion be altered? Could a person prepare to move
Softa [21]

Boston is colder than Miami.

Therefore, more water is lost in the form of sweat in summer than in winter. In the summer, your body becomes dehydrated, releasing more ADH in your body.

ADH Syndrome of antidiuretic hormone or vasopressin is synthesized by the hypothalamus and released from the posterior pituitary gland to maintain blood osmolality. It increases the reabsorption of water from the kidney nephrons.

Therefore, in a cold environment like Boston, ADH will be low and will increase significantly in Miami.

Several chemicals change ADH levels.

Drugs that raise ADH levels include vasotrict and vasopressin.

Drugs that lower ADH includes alcohol.

Therefore, some chemicals can affect ADH levels in the blood.
