"Survival of the fittest" is the one among the following choices given in the question which is an aspect of Darwin's theory that is shown as an example in this scenario. The correct option among all the options that are given in the question is the third option or option "c". I hope that this answer has helped you.
<u>Answer</u>:
1. C. Process one describes cloning and process two describe artificial selection
Through cloning a genetically identical individual is obtained from a single individual. Through artificial selection a hybrid between two individuals with desirable traits is obtained.
2. C. Polygenic
A trait that has a continuous variation has a polygenic inheritance pattern as it is controlled by multiple genes.
3. C. The BW mice would have black and white patches
Codominant genes will produce an individual with an intermediate phenotype as both alleles are simultaneously expressed in the heterozygote.
4. D. Polygenic
Polygenic inheritance occurs when two or more genes determine a trait that has a continuous variation. Each gene has a small effect, but all together have a cumulative effect. Examples of such patterns are height, sking color, eye color, weight etc.
Answer:
The correct answer would be C. ³⁵S has more neutrons than ³²S; Hershey and Chase used it because it is radioactive and can be easily traced.
Sulfur-35 (³⁵S) is one of the isotopes of the sulfur which has 16 protons (same as sulfur-32) but 19 neutrons as compared to the 16 neutrons of sulfur-32.
It is a radioactive isotope which breaks down by beta-decay and gets converted into ³⁵Cl.
They used ³⁵S for radioactive labeling of the protein coat of the bacteriophage. It helped them to trace the movement or transfer of protein efficiently.
Rachel is a frail and fragile girl who is prone to injury and bruising William Sheldon would most likely have classified her body as a ectomorph.
William classified people according to their body into three types:
1. Endomorphs- rounded and soft, with comfortable and extroverted personality,
2. Mesomorphs-square and muscular, with dynamic and aggressive personality,
3. Ectomorphs-thin and fine-boned with introverted, and sensitive personality.
Carbohydrates glycaemic index (GI)
Glycemic index estimates
carbohydrates containing food based on how they increase the glucose in the
body. Foods are rated by comparing them to a reference food. Foods with high glycaemic
index increases blood glucose than foods with average or low glyceamic index. When taking foods with high GI, low GI foods
should be combined with it in order to balance the meal. Examples of low GI
foods are corn, most fruits, and yam. Medium GI foods include pita bread and
whole wheat. Puffed rice, instant oatmeals are examples of foods with high GI.
