Answer:
Explanation:
A scientific researcher performs scientific methods to answer any natural process. The researcher will follow the protocol of a scientific method which includes: observe the natural phenomenon, ask related questions, suggest a hypothesis, perform the experiment and suggest answers.
In the given question if the researcher has to study about the flu virus, the possible questions he would ask will be:
1. The life cycle of the flu virus.
2. Effect of the virus on the life of an organism.
3. The mechanism used by the virus to replicate and to infect any organism.
4. Molecular mechanism of a virus.
Answer:
The correct answer would be C. With an input of energy, ADP combines with a phosphate group to become ATP.
Inorganic phosphorus and energy are added to adenosine diphosphate (ADP) in order to convert it to adenosine triphosphate (ATP).
This reaction is usually catalyze by the enzyme ATP synthase. It present in inner membrane of mitochondria of the cell as well as in the thyllakoid membrane in chloroplast.
ATP synthase uses the energy provided by chemiosmosis i.e. flow of protons down the gradient across the membrane through this enzyme. Proton gradient is formed either by photosynthesis or by cellular respiration.
ADP + inorganic phosphate (Pi) + energy → ATP + H₂O
ATP is used as the energy currency of the cell which breaks down to release inorganic phosphate group and energy which is used in various metabolic processes.
<h2>
A change in one base of the gene sequence is known as point mutation.</h2>
Explanation:
Question 2 is incomplete.
3. A mutation that only affects a single nucleotide of nucleic acid is known as Point Mutation.
In Point mutations there is substitution of one base for another.
Example: TAT TGG CTA
TAC TGG CTA
The TAT changes to TAC which shows point mutation.
4. Yes. The point mutation have an effect on the outcome compared to the normal sequence.
When there is a change in one base of the gene it results into causing disease such as cancer, sickle cell anemia.
Answer:
Option A and C and D
Explanation:
Gylcogen is synthesized through a series of reactions through the assistance of enzymes. When glucose enter into the cell, it is converted into glucose 6-phosphate and then into glucose 1-phosphate and finally into uridine 5ʹ-diphosphate-glucose. In glycogenesis, glycogen is broken down into glucose 1-phosphate with the help of two glycogen phosphorylase. In the next stage the glycogen debranching enzyme untangles the branch points.
Hence, option A and C and D are correct
Answer:
B. physical anonymity.
Explanation:
Anonymity can be explained in psychological research as a situation whereby the data collected from participants is confidential and cannot be traced to any particular individual.
Deindividuation is known to be a phenomenon in which people engage in seemingly impulsive and sometimes violent acts in situations in which they believe they cannot be personally identified.
In this case, people that are not physically present tend to be more hostile or engaged in some cruel act. This is because they know they can be seen face-to-face, and people will not know that they are the perpetrator of the act.
