Answer:
Explanation:
Studies indicate that mining is one of the most perilous occupation in the world in terms of injuries and fatalities, and also due to the long term health effects associated with it. Long term effects include respiratory problems such as pneumoconiosis, asbestosis, and silicosis.
Clues such as fossils such as bones, footprints, tar, etc, preserved underground helped inform scientists. You can also count how old a tree is when you cut it open and there are some alive for thousands of years so that is a possible way.
Answer:
S3xual selection as a consequence of female choice is easy to understand, provided we are willing to accept that female preferences exist. If females show a preference, then males with the preferred trait will leave greater numbers of offspring, and their trait values will tend to increase in frequency in the population.
Explanation:
Answer:
Nucleus
Explanation:
The nucleus is the genetic center of the eukaryotic cell because it contains the genetic material (DNA, RNA) used for the storage of genetic information
Answer No 2:
The correct option is C. <u>Substitution of 3rd N-base to go from UCU TO UUU </u>has the potential to cause more damage.
Answer No 3:
UCU codes for the amino acid serine whereas the code UUU is for phenylalanine. A change in this base has caused the entire amino acid to change which will result in the formation of the wrong protein.
Whereas the changes in the base sequence of the options A and B do not change the amino aids being made. Hence, the changes in options A ans B will be less damaging then the option C.
Answer 4:
In the field of genetics, a stop codon can be described as a signal which stops the translation. It is a three nucleotide sequence which is recognized as a terminator.
If stop codon is not present at the right place, then the process of translation will not terminate at the right place and wrong proteins will be made.
