Answer:
1- Presence of phenotypic variation
2- some phenotypic variation due to genetic variation
3- the given trait has an impact on fitness
Explanation:
The evolutionary theory by natural selection proposed by Darwin in his publication “On the origin of species” (1859) is based on a series of assumptions that enable to understand the amazing biodiversity on the Earth. First, individuals are not identical among them, i.e., there exists variation in the traits among the members of a given population, species, etc. Second, phenotypic variation leads to differential survival and reproduction of the organisms that are best fitted to the environment (i.e., competence among the members of the population). Finally, phenotypic traits are passed from generation to generation (i.e., phenotypic variation is inheritable), thereby favoring offspring from parents more adapted to the environment.
Answer:
C
Explanation:
When examining the trends in coastal position over a time frame, you perform shoreline change analysis. In most cases, coastal changes are very non-linear.A normal regression of the shoreline happens when there is supply of sediments where the base level is rising at the shoreline.Here the rate of sediment deposition is more than that at which the base level is rising at the shoreline.
The movement ofa shoreline seawards due to sedimentation at the coast is called regression.If this movement is due to sea-level fall like in our case in the question it is force regression.In option C, the sea level is falling.
Answer:
The value of the expression is as follows:
a = 10; B = 2.5; c = 7
Explanation:
a = 4B = 3 + c = 10
Step 1
split equation into parts, then we have
3 + c = 10
c = 10 - 3
c = 7 (the value of c is 7)
Step 2
Rewrite equation as a = 4B = 10, then split again
4B = 10
Then, B = 10➗ 4
B = 2.5 ( the value of B is 2.5)
Step 3
Take the last part of the equation
a = 10 (the value of a is 10)
