Answer:

The food chain is very important. It needs to be running smoothly because if an animal gets extinct, it may create a domino effect. Animals rely on food (prey), to live. If that prey dies, they may not have another food source. If this happens, then that predator would starve and die as well.

Assuming hardy-weinberg equilibrium, if 23 geese in a population of 142 are white, and 119 are blue, how many of the blue geese

WINSTONCH [101]

We solve the problem using the Hardy-Wineberg equation.

Let us start with the homozygous recessive number of white trait,

∴ $q^{2} = \frac{23}{142} = 0.16$

We have the frequency for white trait as q = 0.4

Solving for the frequency of blue trait by using the fact that,

p + q = 1

∴ p = 1 - q = 1 - 0.4 = 0.6

Now we can calculate 2pq in p² + 2pq + q², which is the frequency for heterozygous blue trait,

∴ 2pq = 2 x 0.6 x 0.4 = 0.48

And the homozygous blue trait is given by the expression,

∴ p² = 0.6² = 0.36

Hence, the carriers for the trait of blue are, 0.48, or 48% of 142.

∴ 48% of 142 = $\frac{48 \times 142}{100}$ = 68.

Answer is 68.

Lana71 [14]

Answer:

D) dandelion

Explanation:

Plants make their food using a process called photosynthesis, which means “putting together through light.” During photosynthesis, a plant traps energy from sunlight with its leaves. It also takes up water from its roots and carbon dioxide gas from the air.
