If you’re trying to figure out if it’s true or false it’s true
Answer:
Option B
Explanation:
In biology, fitness refers to the ability of an organism to survive, reproduce, mate and support evolution through gene transfer. A fitness of 0.28 signifies that only 28 percent of a given population are fit physically and able to reproduce while the remaining 72 % are unable to mate and hence cannot reproduce and contribute towards gene flow and evolution.
Hence, option B is correct
Answer:
Cancer is caused by changes to certain genes that alter the way our cells function. Some of these genetic changes occur naturally when DNA is replicated during the process of cell division. But others are the result of environmental exposures that damage DNA.
Answer:
The correct answer is a. Reduction in species diversity
Explanation:
In habitat fragmentation, the large area of forest is divided into many smaller patches which reduce the area of habitat for species live there. This Fragmentation of habitat occurs mainly due to human activities like making highways and roads in the area.
This separates species member from each other which reduces the gene flow between that which can lead to inbreeding depression in a species and extinction of species can occur.
Cutting trees and human activities can alter the environment negatively which can cause extinction of some species that reduce species diversity. So the correct answer is a.
