The birds shown above have beaks with three different shapes and sizes. The genetic variations on the beak each appeared initially due to

Answer 1- mutations

Look at the three beaks which flock's birds have beaks that seem most likey to Pierce a piece of fruit?

Answer 2-Flock X

Suppose that s plant disease kills all fruit. The change could become a

Check all possible effects of this selective pressure

Answer 4- 1, 2, 3, and 4 are true.

Flock x may try to eat other foods -True

Flock x could migrate in search of fruit -True

Flock Y and Z could benefit and increase- True

Flock x could try to mutate- False

In this example, we used lotka-volterra equations to model populations of rabbits and wolves. let's modify those equations as fo
Daniel [21]

Answer:

Wolves absence would lead the rabbit population to become stable at 5,000.

Explanation:

Step 1. Concept

If there is a missing variable that should be in the system, set that particular variable to zero and make the necessary conclusion.

Step 2. Given,

dR/dt = 0.08R(1 - 000.2R) - 0.001RW

dW/dt = −0.02W + 0.00002RW

Step 3. Calculation

The transformed equations of populations of rabbit and wolves will be

dR/dt = 0.08R(1 - 000.2R) - 0.001RW

dW/dt = −0.02W + 0.00002RW

Let's check the rabbit population in the absence of wolves(W) to 0

Thus,

Differential equation dR/dt

dR/dt = 0.08R(1 - 000.2R) - 0.001RW

Take W to equal to O

dR/dt = 0.08R(1 - 000.2R) - 0.001R(0)

dR/dt = 0.08R(1 - 000.2R)

When,

dR/dt = 0 we have R = 0 or R = 5,000

This,

R = 5,000 becomes the equilibrium point in the absence of wolves

Then,

0 < R < 5,000, dR/dt > 0

For R, let's estimate a value rise of the rabbit population to 5,000

Then,

R > 5,000, dR/dt < 0

Judging from the value if R, we infer a deduction in the rabbit population by 5,000

Thus,

We can conclude that wolves absence would lead the rabbit population to become stable at 5,000.
