A problem of interest to health officials (and others) is to determine the effects of smoking during pregnancy on infant health.

one measure of infant health is birth weight; a birth weight that is too low can put an infant at risk for contracting various illnesses. since factors other than cigarette smoking that affect birth weight are likely to be correlated with smoking, we should take those factors into account. for example, higher income generally results in access to better prenatal care, as well as better nutrition for the mother. an equation that recognizes this is

Explanation:

This rapid population growth has an adverse effect on the natural resources and quality of life.

However, overpopulation has a deleterious effect on the environment due to the current lifestyle.

There would be rampant exploitation of natural resources, excess human waste accumulation, chances of epidemics, etc.

Besides, it would also lead to socio-economic problems like poverty, malnutrition, violence, corruption, etc.

Human overpopulation occurs if the number of people in a group exceeds the carrying capacity of the region occupied by that group.

Answer/ Explanation:

The original DNA sequence has a point mutation changing a G to a T. The resulting mRNA produced is always complementary to the DNA from which it is synthesised, so the original mRNA sequence has a T, whereas the mutated mRNA has a U. The tRNA is complementary to the mRNA, so the original has a G, and the mutated has a T.

This is a point mutation called a substitution. This does not affect the entire sequence of the protein, because the mutation is "in frame" meaning the mRNA sequence is still read in the same way by the protein producing machinery. However, it does change the 5th codon from UGC to UGU. If we look up the genetic code, we can see that both of these codons code for cysteine, so there will be no change in the amino acid sequence of the protein
