Melting temperature of RNA duplex will be higher

Explanation:

  • RNA is a double stranded RNA with two complementary sequences
  • Duplex DNA is simply double stranded DNA
  • It is known A=U base pairs of duplex RNA is less stable than that of A=T base pairs of duplex DNA
  • RNA duplexes are considered to be more stable than DNA duplexes of comparable sequences but physical basis for thermal stability is not much known hence melting temperature of RNA duplex will be higher

kakasveta [241]

Answer:

This is an example of founder effect.

Explanation:

Founder effect may be illustrated as the loss of genetic variation in a novel small population originated from the original population. The concept was initially presented by Ernst Mayr. It can be seen that genetic diversity has got reduced in the population of iguana due to the result of the flood that has washed all the iguana without webbed feet into the sea.  

The new population has got inclined from the small iguana population. Thus, the iguana population is regarded as an illustration of the founder effect.

If you observed the sister chromatids separating during cell division, what phase of mitosis would you be observing?
Sidana [21]
This is the anaphase of mitosis. Anaphase is characterized by the separation of sister chromatids or "pulling away" of the sister chromatids from the metaphase plate to the opposite spindle poles. This is also the phase where chromosomes reach its maximum condensation meaning that the process of the reformation of the nucleus will be shorter and easier.

Norma-Jean [14]
Many farmers in less densely populated area, such as Amazonia, practice slash and burn agriculture, also known as shifting cultivation or swidden agriculture where an area is cleared and then burned for the vegetative remains to release nutrients back into the soil. Shifting cultivation is a system where a farmer uses a piece of land, only to abandon or alter the initial use a short time later. Advantages of shifting cultivation includes; enhance control of pest and disease, inorganic matter addition which provide nutrient to crop, an effective way of weed control
