Answer: DD and Dd
Why? Dimples are dominant meaning that if one dimple trait is in allele it will be shown even if there is a recessive trait. So DD and Dd are the answers
Answer:
Option C
Explanation:
The null hypothesis is the problem statement and alternative hypothesis is counter of the null hypothesis.
Hence, the null hypothesis here is the rate of extinction was neither higher nor lower when there were sudden climatic changes (asteroid strike)
And alternate hypothesis is "the rate of extinction was either higher or lower when there were sudden climatic changes (asteroid strike)"
Hence, option C is correct
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
Another pair of organisms are in the same genus
What you have to bear in mind is to make the compound charged, in order that it will be soluble in water than in ether. You should make the pH basic for acid as in the salt compound in order to cause the acid to dissolve in the water layer.<span> </span>
