As far as I can tell, the answer would be D. Adaptation. The birds are evolving to adapt to their environment, and as such, their beaks are getting larger to crack larger seeds.
To solve the question we proceed as follows;
time=distance/speed
distance between the monkeys is 2km=2000m
But the speed of sound= 330 m/s
Therefore the time taken for a howler monkey to get to the other will be:
time=2000/330
=6.1 seconds
The answer is 6.1 seconds
Answer:
A is correct based on the chart and characteristics.
Answer:
C. Natural selection favors individuals that reproduce more than others.
Explanation:
Genetic variations present in the population are acted upon by natural selection. The organisms that have the adaptive traits which in turn make them able to survive and reproduce more than the other individuals are favored by natural selection.
Over generations, natural selection leads to the evolution of a new population with an increased frequency of the gene responsible for the selected adaptive trait.
For example, the bacteria with antibiotic resistance were favored by natural selection as they can survive and produce more progeny in the presence of antibiotics than the bacteria lacking the gene for antibiotic resistance.
Answer:
(B) Lava has separated the population into two areas: an upland forest and a lowland marsh.
Explanation:
In allopatric speciation, individuals of an ancestral species may undergo evolution into two or more progeny species which arises when physical separation causes a geographic boundary, this barrier can be in the form of a mountain range, rockslide, river or lava.
As in this scenario, a lava flow divides the populations of annual herbaceous plants by altering the landscape. This will cause genetic divergence with varying heritable features among its many generations favouring different traits in the separate environment along with genetic drift. The Lava will separates the population into two areas: an upland forest and a lowland marsh.
