Answer:
scientists can also analyze DNA to discover how closely organisms are related. Every living creature has DNA, which has a lot of inherited information about how the body builds itself. Scientists can compare the DNA of two organisms; the more similar the DNA, the more closely related the organisms.
Answer:
The correct answer will be option-B (Semi-synthetic)
Explanation:
Chemical drugs can be synthesized through many ways on the basis of which they can be categorized:
1. Natural Drug: The drug prepared from the natural extracts.
2. Synthetic Drug: The drug is synthesized by chemical reactions.
3. <u>Semi-synthetic Drug</u>: The drug which is neither completely natural nor synthetic that is they are prepared from the natural extracts by modifying them.
Since in the given question, the drug was prepared by the converting side chain to the hydroxyl group of the antimicrobial drug therefore it is considered as the semi-synthetic drug and Option-B is the correct answer.
Answer:
A karyotype is an individual's collection of chromosomes.
Explanation:
The answer is A. Mitosis results in daughter cells through one division cycle while meiosis results in haploid gametes through two division cycles.
The question is incomplete, however, the statements associated with this question is given in the comments and here as well:
Neither facilitated diffusion nor osmosis requires cell energy.
Diffusion of gases and other small molecules requires no energy on the part of the cell.
Active transport requires cell energy and osmosis doesn't.
Both endocytosis and active transport require cell energy.
Answer:
The correct answer is - Active transport requires cell energy and osmosis doesn't.
Explanation:
Osmosis is an example of passive transport as it does not require energy to facilitate the movement of solvent In the process of osmosis,. It moves from high concentration to low concentration through the semipermeable membrane which is along the gradient so no requirement of energy.
In the case of Active transport, it requires energy to facilitate the movement of transport as it is the movement of a substance from low concentration to a high concentration area that is against the concentration gradient.
