Answer:
Amino acid sequences
Explanation:
The proteins perform the vast majority of functions in the cells. If a gene between a human and a mouse is evolutionarily related, it means that the function they do in the cell is quite similar in both species. This is the reason why the amino acid sequence would be the most similar.
In addition, there might be certain mutations in the DNA and therefore in the RNA between this 2 sequences that encode to the same amino acid sequence. More specifically speaking, there are more than one codon that encode to the same aminoacid. Thus, 2 different DNA/RNA sequence can give the same aminoacid sequence.
Answer:
The answer is given below
Explanation:
The genes of the heterozygous pea plant are V for violet flowers, Y for yellow and R for round. Let V, Y, R represent the dominant gene and v,r,y represent the recessive gene.
According to Mendelian theory of inheritance all the genes would be inherited independently.
The expected genotypes of the gametes produced by Mendelian inheritance are VYR, VyR, VYr,Vyr, vYR, vYr, vyR, vyr .
If all three genes are found on the same arm of one chromosome, since the genes are linked to each other, the genes cannot be sorted independently of one another.
Answer:
rainfall made sufficiently acidic by atmospheric pollution that it causes environmental harm, typically to forests and lakes. The main cause is the industrial burning of coal and other fossil fuels, the waste gases from which contain sulfur and nitrogen oxides, which combine with atmospheric water to form acids.
Ozone depletion, gradual thinning of Earth's ozone layer in the upper atmosphere caused by the release of chemical compounds containing gaseous chlorine or bromine from industry and other human activities. The thinning is most pronounced in the polar regions, especially over Antarctica.
the concentration of toxins in an organism as a result of its ingesting other plants or animals in which the toxins are more widely disbursed.
an antigenic poison or venom of plant or animal origin, especially one produced by or derived from microorganisms and causing disease when present at low concentration in the body.
A fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing energy originating in ancient photosynthesis. Such organisms and their resulting fossil fuels typically have an age of millions of years, and sometimes more than 650 million years. Likewise, biodiversity loss describes the decline in the number, genetic variability, and variety of species, and the biological communities in a given area. This loss in the variety of life can lead to a breakdown in the functioning of the ecosystem where decline has happened.
Deforestation is the permanent removal of trees to make room for something besides forest. This can include clearing the land for agriculture or grazing, or using the timber for fuel, construction or manufacturing. Forests cover more than 30% of the Earth's land surface, according to the World Wildlife Fund.Nov 6, 2019
Explanation:
Answer:
Repeated and improper uses of antibiotics are primary causes of the increase in drug-resistant bacteria
Explanation:
. While antibiotics should be used to treat bacterial infections, they are not effective against viral infections like the common cold, most sore throats, and the flu.
