Answer:
B-Information on the number of all whales hit by boats in the given area
Explanation:
If they see that they have some responsibility in harming the whales, it may change their behavior.
The true answer of your question is :
OH : HYDROXYL GROUP
NH2 : AMINO GROUP
CH3 : METHYL GROUP ( but in rather broader terms, that functional group of formula CnH2n+1 where n is an integer is called ALKYL GROUP where by substituting n by 1,2,3... we obtain methyl for n = 1, ethyl for n = 2, and propyl for n = 3 )
COOH : CARBOXYL GROUP is the correct answer since carbonyl is characterized by the presence of functional group C=O in general the formula of the compound would be
R-C=O-R’ where R and R’ are alkyl groups like methyl for example. However the carboxyl group could be thought of as a summation of carbonyl + hydroxyl ( CO + OH ) resulting thus in COOH.
I hope you’ll understand everything, anyway if not i’m always here to help. ♥️
A mutation that involves one or a few nucleotides is called
a) mutagen
b) inversion
c) point mutation
d) translocation
Answer:
c) point mutation
Explanation:
When only one or a few nucleotides of a gene are changed by mutation, this is called a point mutation. A point mutation can add one additional nucleotide to the wild type gene or may delete or substitute a nucleotide from it. For example, if a wild type gene sequence is "ATATATATA", then the addition of "C" at the position 4 will change it into "ATACTATATA". This addition of new nucleotide is called point mutation since only one nucleotide is added to the gene. Point mutations can cause serious genetic disorders such as sickle cell anemia.
Scientists have tried lots of different ways of predicting earthquakes, but none have been successful. They<span> haven't been able to find a signal for earthquakes( there is no obvious sign to say that an earthquake is coming very soon).</span> They do have a pretty good idea of where an earthquake is most likely to hit, but they still can't predict exactly when it will happen.
However, the probability of a future earthquake can be calculated, based on scientific data. Scientists estimate that the probability of a major earthquake occurring in the San Francisco Bay area over the next 30 years is 67%.
I think that people have lost their jobs because of an increase of computers
