Sugar is what yeast needs to “wake it up” or break its dormancy.
Answer:
There is less biodiversity in the ecosystem.
Explanation:
Since the barren ground doesn't provide suitable living conditions for most of the living organisms, the ones that need the lest resources to survive create the primary succession, usually the mosses and lichens. The organisms of the primary succession provide biomass, so the ground is mixing with it, thus new soil is forming.
Answer:
a) high bite force
b) hawks will deplete
Explanation:
a) Hawks and lions have high bite force to rip raw flesh to feed on. Lions also have bite force to ensure that once they grip its hard to let go. Also to feed on raw hard flesh
b) hawks would have less food on the plate do some will die of hunger. Some will flee to a better places. And hence leaving the previous location with low numbers of hawks.
Immigration followed by competition
I hope this right, if its not, sorry =)
Answer:
D
Explanation:
The presence of homeotic genes shows that all of the listed organisms (mice, flies, humans etc) all evolved from a common ancestor.
(A) is wrong as the evidence of the same gene existing in vastly different species shows the evolutionary relationship between these organisms.
(B) is wrong as there is insufficient evidence to prove that flies are the precessor of humans. We do know that flies and humans have evolved from a common ancestor though.
(C) is non-conclusive as the passage said nothing about the gene allowing the species to have a higher chance of surviving and reproducing. Hence, an errornous claim.
(D) is the correct answer as from a common ancestor, all of the listed organisms undergo and accumulates mutation, undergoes selective pressures that resulted in divergent evolution (aka branching evolution that results in many noval species forming) after millions of years.
