Other than contributing to potential increase in diversity of species in an ecosystem, exotic species have positive benefits like removing toxins from the soil, regulating erosion, and controlling undesirable species.
<span>Conjugation in which two cells temporarily combine in order to transfer genetic materials. After combination they then divide again, allowing of the information to pass and replace the previous members of the population.</span>
Answer:
Any combination of D, E and F
Explanation:
Since A, B, and C belong to different orders, and D, E and F belong to the same order, the latter are more closely related and thus are expected to show a greater degree of structural homology. They are closer to their common ancestor than A, B and C.
Answer:
Explanation:
If there are 5 genes, let us assume that they are in the alternative forms with 2 possible gets for each five... So we have
2 possible gametes for each five = 2 to the power of 5 = 32 gametes
Then genotypes = 3 to the power of 5 = 243
The same also for 10 genes
2 possible gametes for each 10 = 2 to the power of 10 = 1024 gametes
Then genotypes = 3 to the power of 10 = 59,049
The same also for 20 genes
2 possible gametes for each 20 = 2 to the power of 20= 1,048,576
Them genotypes = 3 to the power of 20 = 3,486,784,401
