False

In case of all polar molecule the amount of inter molecular forces (such as cohesion, adhesion etc.) is much smaller than intramolecular forces (such as dipole –dipole interactions, Hydrogen bonding etc.)

Due to this reason a polar molecule form a dipole –dipole structure due to which the charges are unevenly distributed on different parts of  neutral molecule. The electrons are more strongly oriented towards oxygen atom and thus it gets negatively charged and hydrogen gets positively charged. A polar molecule attract another polar molecule either through Hydrogen bonding or through dipolar attraction between them.  

For example dissolution of HCl in water is a polar -polar molecule interaction.

olga2289 [7]

Answer:

The correct answer is -

1. protein synthesis or central dogma

2. leads to changes in the structure by changing in the codes which results in a decrease or loss of function.

Explanation:

1, Protein is made from the information coded in DNA base sequences by the two process protein synthesis that is also called central dogma. The two-process involve in this are transcription involves encoding the information present in DNA by mRNA molecule that codes the information in complementary sequence to DNA. which is then moved out of the nucleus and perform the translation with help of tRNA and ribosome to code the amino acid with help of triplet codes present in mRNA. These amino acids chain are called proteins.

2. Mutations can lead to change in the base sequences or deletion of the base which affects the structure of the protein and also leads to changes in an encoded protein or to a decrease or complete loss in its function or expression. Mutation can damage the cell or organism as it affects the gene expression of all cells of organisms.

dalvyx [7]

Answer:

C) Yes, the six-week-old cousin should be considered at risk.

Explanation:

young are at higher risk of pertussis  as compared to older children and adult because  young infants are not fully immunized. At the young age of 6 week, the cousin may not have started the DPT vaccination.  so babies at this age gets easily affected when they are in contact with the infected people.
