Evolutionary theory focuses on the long term adaptation of the species over more generations. Every species has 2 long-standing biologically based drives: survival and reproduction. Other answers are not biologically based drives for every species.
Answer:
A ) survival and reproduction.
Answer:
Natural selection causes changes in populations because of the differential reproductive success of genetically varied individuals. That's the correct answer, for the selections that you have provided. Therefore, the correct answer in the selections you have provided would be letter B above; that's the true one!
Answer:
The correct answer will be option-E.
Explanation:
The CRISPR-Cas9 system is a simple and most versatile genome-editing tool to edit the genome of an organism.
The system consists of two components: "Cas-9 enzyme" which act like molecular scissors to cut the DNA and "Guide RNA or gRNA" which guides the Cas-9 enzyme to the target DNA by binding to the target DNA.
The gRNA consists of 20 bases long RNA sequence which is complementary to the sequence of the target DNA. This binding ensures the right binding and cutting of the target DNA.
Thus, option-E is the correct answer.
STARCH
Starch is a complex carbohydrate that is found in potatoes, whole grains and cereal grains, which consists of numerous glucose strands. Eventually, all complex carbohydrates -- with the exception of fiber -- are digested into glucose. Starch is a simple sugar, which is the smallest form of carbohydrate, and is the main source of energy for all cells. While both starch and glucose are considered carbohydrates, they have different effects in your body.
GLUCOSE
Glucose occurs naturally in fruits and vegetables but is also added to processed junk foods as a sweetener. Glucose absorbs through intestinal walls and enters your bloodstream rather quickly. Whole foods, such as fresh produce, also contain fiber, which delays glucose absorption. Whole foods also minimize the chance that a spike in blood sugar will occur. Processed foods are usually low in fiber, so that the glucose goes straight to your blood, quickly elevating your blood sugar.
