No. Yes phenotypes are important for example those with longer legs can run faster and hence escape predators
But genes also code for unseen proteins
For example, if a disease is introduced those with long legs won't survive but those who have the genes which code for the complimentary antibody have the ability to kill the pathogen and hence survive.
Answer:
b
Explanation:
The correct answer would be 45.
Assuming that the 10 soils are each represented by A, B, C, D, E, F, G, H, I, J.
A can combine with 9 others as: AB AC AD AE A F AG AH AI AJ
B can combine as: BC BD BE BF BG BH BI BJ
C as: CD CE CF CG CH CI CJ
D as: DE DF DG DH DI DJ
E as: EF EG EH EI EJ
F as: FG FH FI FJ
G as: GH GI GJ
H as: HI HJ
I as: IJ
Adding all the combinations together = 45
In other words;
= = 45
If you look at different sessile aniimals, you'll notice that they are generally filter feeders- they suck in nutrients from their surroundings. Those that are larger and can "pull in" more nutrients than others. Holometabolus insects do it because the larvae can eat and inhabit a different place than the adults so there is no competition for resources, like food. Lepidopterans are a good example, caterpillars eat leaves and plants while the adults pollinate flowers and drink nectar.
