Answer:
When a species goes into hibernation, the heart rate drops drastically, and the body temperature does as well, in order to conserve energy. The body becomes induced into a comatose state by releasing chemicals from the brain to body to go into sleep mode.
Explanation:
Hibernation usually occurs during the winter.
<span>When an overwhelming body of observations and measurements supports a scientific hypothesis or group of related hypotheses, it becomes a scientific theory. A scientific theory is defined as an explanation of an facet of the natural world that one can test repeatedly using defined protocols of observation and experimentation.</span>
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:
CAT - GGC - TAC mutates to CAT - GGC - TAG
Explanation:
Changes occur in the nucleotide sequence of the DNA molecule. These changes referred to as MUTATION are usually due mistakes during DNA replication or induced by mutagens (mutation-causing substances). Mutation can be of different types depending on the kind of change that occured to the nucleotide sequence. Based on this question, one of the mutation types is SUBSTITUTION MUTATION.
Substitution mutation is a kind of mutation in which one or more nucleotide base replaces another in the sequence.
The option that suits an example of substitution mutation is: CAT - GGC - TAC mutates to CAT - GGC - TAG because Guanine nucleotide replaces Cytosine nucleotide in the third CODON i.e. TAC becomes TAG.
