<span>The answer to your question is that all of the energy is ultimately radiated into empty outer space as heat. The second law of thermodynamics mandates that all processes that involve the transfer of energy MUST radiate a portion of this energy into space as waste heat. This is why when you run down the street you get hot and sweaty, and this is why automobiles MUST have a functioning radiator and nuclear power stations MUST have evaporation cooling towers or else be located near a large body of water to exchange excess waste heat into, etc., etc. It is also true that the transfer of energy at each step up the food chain is very inefficient. They say it takes around 50 lbs of corn to produce one pound of beef, and it probably takes 20-30 pounds of beef to produce one pound of human tissue. The rest of the energy just goes into your living room as radiated body heat. I hope this helps.</span>
Answer:
The options
a. sympatric speciation; vicariance
b. allopatric speciation; vicariance
c. sympatric speciation; dispersal
d. allopatric speciation; dispersal
The CORRECT ANSWER IS d.
d. allopatric speciation; dispersal
Explanation:
Allopatric speciation takes place either via dispersal, when some members of a species shifts it's habitat to a separate geographical area which leads to differentiation of the initial group into separate diverse varieties or species(as in our case study).
Allopatric speciation through dispersal could results in multiple speciation leading to an individual original species producing diverse new species; this occurrence is called adaptive radiation.
In some scenario, a population of an individual species disperses all over a region with each locating a separate niche or isolated habitat. In the course of time, the diverse demands of their just formed lifestyles causes multiple speciation events that comes from a singular species.
The question is incorrect so the answer consists of the genetic context of meiosis.
Answer:
Two main types of cell division are mitosis and meiosis. Meiosis is the process of cell cycle division in which the parents cell divides into the four daughter cells. This division is also known as reductional division.
In meiosis, the gametes are haploid where as the parent cell is diploid in nature. The cell undergoes the two meiosis division, the first division is reductional in nature whereas the second meiosis division is same as the mitotic division. This division occurs in the sex cells and results in the formation of haploid gamete hat restores deiploidy during fertilization process. Crossing over during meiosis bring variation in the cells.
If you're a carrier, you're a heterozygote...So let's say S is normal allele and s is diseased allele, then you'd be Ss.
Someone with sickle cell anemia would be ss (homozygous recessive)
I believe dominance is the answer.
