Answers

Answer 1

Answer: The definition of crest is something that is located at the top of something

Answer 2

Answer: A crest is the highest point the medium rises to and a trough is the lowest point the medium sinks to. Crests and troughs on a transverse wave are shown in Figure 1. Figure 1: Crests and troughs in a transverse wave.

Darwin wrote many of the premises of 'The Theory of Evolution by Natural Selection' by noting differences in the passerine birds of closely related
Galapagos finches, while studying in the Galapagos Islands.

Galapagos finches are also termed as Darwin's Finches.

Answer:

beaks and finches

Explanation:

If a mutation introduces a new skin color in a lizard population, which factor might determine whether the frequency of the new allele will increase? A)how many other alleles are present
B)whether the mutation makes some lizards more fit for their environment than other lizards
C)how many phenotypes the population has
D)whether the mutation was caused by nature or by human intervention

Answers

The answer is B) whether the mutation makes some lizards more fit for their environment than other lizards.

If a mutation introduces a new skin color in a lizard population and that mutation makes some lizards more fit for their environment than other lizards then the frequency of the new allele will increase. For example, if a mutation causes some dark skin color which can help some lizards to survive. The more lizards with dark skin color will survive, and after some time, the frequency of the new allele will increase.

Answer:

1. on end of figure 17-1 shows an increase in average beak size for a population of birds.

Directional stabilization

2. Figure 17-2 shows highest fitness toward the center of the curve.

Stabilizing selection.

3. Figure 17-3 shows smaller and larger beaks in a population of finches.

disruptive selection

4. If a mutation frequency introduces a new skin color in a lizard population, what factors might determine whether the frequency of the new allele will increase

whether the mutation makes some lizards more fit for their environment that other lizards.

List in the order the major blood vessels, chambers, and valves through which a drop of blood must pass in traveling from a vena cava

Answers

Deoxygenated blood flows from the vena cava, into the right atrium, it's then pumped through the atrio-ventricular valves and into the right ventricles. It is then pumped from the right ventricles through the semi-lunar valves to the pulmonary artery where deoxygenated blood is carried to the lungs

Which of these is most likely to produce heavy metal waste? A. Leather tannery
B. Medical center
C. Paper mill
D. Oil refinery

Answers

Answer:

Option A, Leather tannery

Explanation:

In a leather industry, chromium is one of the heavy metals that are used in large amount.

Along with tannery, Chromium is also used in electroplating, and metallurgical industries.

The water coming out of these tannery has high content of chromium ion (Cr6+) generally ranging between 100–200 mg/L. This chromium rich water needs sufficient treatment before discharge or else it would cause bio magnification effect

Hence, option A is correct

C. A paper mill (APEX)
