Answer:
Option B, ionic bonds; salt
Explanation:
All medicines either in the form of pills or liquid interact with our body by forming a bond with target specific receptors. For instance if a pain killer is taken then it shall form bond with receptors produced by pain and inflammation
So medicines are basically chemical which interact with biomolecules such as enzymes, nucleic acid, hormones, ions etc. by forming ionic bond, hydrogen bond, van der wall force etc. in the active site of enzyme.
These salt molecule remain stable in normal conditions but as they come in contact with digestive system of the body (with different pH) they release the drugs
Hence, option B is correct
Answer:
The correct option is C. Drawing a conclusion
Explanation:
The scientific method can be described as a method through which all the scientific questions are tried to be answered.
The scientific method begins with a question. To answer the question, a hypothesis is generated. Experiments and observations are made to test the hypothesis. Based on the data from experiments and observations, conclusions are drawn. Hence, the statement 'based on the data, we determined that plant growth is affected by the type of soil' best illustrates a conclusion.
Answer:
Gas
Explanation:
Gas has no definite shape and all.
Nicked circle is the reason.
Explanation:
During recombinant DNA technology the gene of interest is ligated to plasmid DNA by excision with molecular scissors or endonuclease enzyme and ligated with enzyme ligase.
Enzyme ligase catalysed by ATP seals the nicks by making phosphodiester bonds in the ds or ss DNA and release of ADP.
The ligation in the plasmid did not occur properly hence the replication is interrupted hence no new plasmids with gene of interest replicated in the ligation carried out.
