Question
Choose the false statement
1. Heterotrophs perform photosynthesis 2. Neanderthal had a larger cranial capacity than modern humans 3. The concentration of green house gasses in the atmosphere is increasing. 4. Mammals are animals
Determine if the following example of microevolution is an example of mutation, gene flow, or genetic drift. A F4 tornado rips through the plains in central Kansas, killing 80% of the prairie dog population.
This is an example of gene flow.
This is an example of genetic drift.
This is an example of mutation.
1.This is an example of gene flow.
2.This is an example of genetic drift.
3.This is an example of mutation.
Explanation / Answer
(i) Correct answer:- (1) Heterotrophs perform photosynthesis.
Explanation-(1) Heterotrophs do not perform Photosynthesis.
- these survive through respiration, using oxygen and an energy source (carbohydrates, fats or protein) to produce ATP. So it is false option.
(2) Neanderthals have large cranial capacity, which at 1,600 cm3 which is larger on average than that of modern humans. It is right.
(3) The concentration of green house gasses in the atmosphere is increasing. It is right option.
(4) Mammals are animals. So it is right option.
(ii) Correct answer:- (2) This is an example of genetic drift.
Explanation-genetic drifts Results when chance events occur that limit population size.
-Genetic drift is RANDOM.
