Answer:
C. 25°
Explanation:
Prepare a sketch such that the first line with points VRS intersect the line with points TRW at R where ∠WRS and ∠VRT are vertical angles.
Because line TW intersect line SV at R, then ∠WRV and ∠SRT are vertical angles.
The sum of ∠SRT and ∠VRT =180°
Thus (25x +30)°+(5x)° =180°
25x +30° +5x =180°
30x= 180°-30°
30 x = 150°
x= 150/30
x= 5°
∠SRT = 25x+30 = 25*5 +30 =155°
∠WRS= 180°-155°=25°
Answer:
In artificial selection, humans have the capacity to influence certain characteristics of organisms by selective breeding. One can choose desired parental traits determined by genes, which are then passed on to offspring.
Dog breeding is another prime example of artificial selection. Although all dogs are descendants of the wolf, the use of artificial selection has allowed humans to drastically alter the appearance of dogs.

Answer:
The type of mutation would be the frame shift mutations
Answer:
The only one I can think of now is Plants
Explanation:
Answer:
Organism having the suitable traits appears more in the population.
Explanation:
Natural selection is a non-random process in the biological traits becomes less or more common in the population due to the different rate of survival of their bearer or their differential reproduction.
Natural selection leads to evolution because those organisms are selected to survive and reproduce which are having those traits that are better suited to a certain set of environmental conditions over others. As a result, the number of these organisms increases over time and they appear more in the population.
So natural selection leads to evolution as an organism having the suitable traits appears more in the population.
