I’m almost 100% sure it’s D, because environmental factors can induce a mutation. A mutation can be beneficial but it can also be harmful, so it’s neither B or C, and it can’t be A, because mutations can come from natural selection as well. So it’s D.
A coral reef is a complex [ecosystem] of calcium carbonate shells that are home to microbes, algae, invertebrates, and fishes, and its high productivity helps provide great species richness.
Answer:
What will most likely happen in these lakes is that there will be a decline of several fish populations. The correct answer is A.
Explanation:
The options attached to the question are given below:
A. The decline of several fish populations
B. An increase in the number of fish.
C. An increase in the number of primary producers.
D. Increased predator- prey relationship.
The fishes, just like any other living organisms has ideal body temperature and pH at which they act best. The ideal pH for fish living in lake water is between 6 and 8. If the pH is reduced below this value then the water will become acidic and this will be toxic for the fish population living in the lakes. Therefore, those fish that can not cope will die and there will be a decrease in the fish populations.
Answer:
Has three dominant alleles
Explanation:
Skin colour is a polygenetic inheritance and it is controlled by three genes pairs of alleles. The human skin is determined by the amount of melanin it contains. A combination of melanin producing alleles determines the skin color.
In the above question, the person has a skin color that is midway meaning only half of the alleles produced melanin. The total number of alleles is 6 and half of it is 3. So, only 3 alleles were dominant and the remaining three were recessive.
Answer:
can adapt to environment, access to food, ability to mate and reproduce
Explanation:
yea this should be right
