Explanation:
Natural selection is the mechanism that is responsible for the evolution of organisms.
In the given case, the Freshwater shrimp has been introduced to a pond in which the two species with variations are introduced.
The <em>C. cantonensis </em>is brighter in color whereas the <em>C. multidentata</em> is mottled drab in color. The predator fish can feed easily on the species which is brighter therefore <em>C. cantonensis</em> is more susceptible. The mottled drab species is not easily predated by the species.
The 30 % offsprings of <em>C. cantonensis</em> can survive till the reproductive age whereas 75% of C. multidentata. This shows that natural selection has acted on the color of the shrimp species selected against the predator fish species.
The species with mottled drab color is the result of the differential reproductive rate.
Answer:
1: Burning of fossil fuel
2: Deforestation
3: Waste disposal in landfills
Explanation:
Burning of fossil fuel is the one of the primary cause of increased level of carbon dioxide in air. Deforestation refers to uncontrolled cutting down of trees which in turn increases the level of carbon dioxide in air. Plants are the natural resources that remove the carbon dioxide from air through the process of photosynthesis. Waste disposals in landfills emits methane which is one of the greenhouse gas.
Answer:
The answer was A
It's a Heterotroph
It's means they eat thing outside of themselves instead of producing their own food.
I believe it's correct
Explanation:
Answer:
oxygen
Explanation:
6CO2 + 6H2O + light ----> C6H12O6 + 6O2
Oxygen (O2) is an element, so it cannot be broken on smaller units.
Answer:
t describes Linus Pauling's contribution to the understanding of DNA structure?
Having first discovered the spiral shape of proteins, Linus Pauling used x-ray technology to hypothesize that the DNA molecule consisted of two consistently spaced strands that formed a spiral shape.
Linus Pauling studied DNA base pairing.
Having originally studied proteins, Pauling proposed that DNA was a three-chained helix with a sugar-phosphate backbone at the center and bases sticking out from the backbone.
Linus Pauling conducted experiments to prove that DNA carried genetic information.
