Consider the quote from evolutionary biologist Theodosius Dhobzhanzky: “Nothing in biology makes sense except in light of evolution.” Give an example of two different species, in two different domains of life, where this is prominently displayed. Provide a source.

44.Why don’t similar genotypes always produce the same phenotype?

A. Parent alter their phenotype and pass on this phenotype to progeny

B. Phenotype is the product of many environmental influences

C. Genetic variations of ADH enzyme produce the same phenotype

D. Animals display different phenotypes dependent on diet, not genotype

46.Which of the following attributes has the least effect on the contribution an individual makes to the gene pool of the next generation?

A. spas of mating privileges

B. more efficient at obtaining food

C. produces more offspring

D. camouflage from predators

47.”Until the agricultural evolution 10,000 years ago, people used to live in small populations with little gene flow between them. That is the best situation for rapid evolution.” said Sewall Wright. one of the founders of population genetics. This conclusion on gene flow conflicts with Hardy Weinberg equilibrium, which states that no gene flow means

A. natural selection

B. no evolution

C. no random mating

D. no genetic drift

58 Larval flies (maggots) express the Ubx gene in all of their segments, and thereby lack appendages. If this same gene continued to be expressed throughout subsequent developmental stages, except in the head region, and if the result was a fit, sexually mature organism that still strongly resembled a maggot, this would be an example of

A. homochrony

B. exaptation

C. paedomorphosis.

D. adaptive radiation

3. Some Caminalcules went extinct without leaving descendents. In the real world, what intrinsic factors (i.e., related to an organism’s basic reproductive biology, population biology, ecological niche, etc.) or extrinsic factors (e.g., ecological/environmental factors) might increase or decrease the probability of a species going extinct? PLEASE DO NOT REFER TO HUMAN-CAUSED EXTINCTIONS IN YOUR ANSWER.

4. Find two additional examples of convergent evolution among the modern-day Caminalcules. This means finding cases where two or more species have a similar characteristic that evolved

independently in each lineage. The wing of bats, birds and bees is an example of

convergence since the three groups did not inherit the characteristic from their common

ancestor. Write your answers in complete sentences (e.g.,“Species x and y both have ____

but their most recent common ancestor, z, did not”). List two additional real-world examples

of convergent evolution (ones that we have not already talked about in class) and discuss

what might have caused the convergence.

5. a. Describe two examples of vestigial structures that you can find among the

Caminalcules. These are structures that have been reduced to the point that they are

virtually useless. Ear muscles and the tailbones are examples of vestigial structures in our

own species.

b. Explain how vestigial structures provide clues about a species’ evolutionary past.

Illustrate your argument with vestigial structures found in humans or other real species.

Kindly answer question 3 to 5 thank you.

While Jill and Andre were studying for their Biology exam, Andre said, “Animals perform cellular respiration and plants perform photosynthesis.” What about Andre’s statement should Jill have told him was incomplete?

Animals also perform photosynthesis.

Plants do not perform photosynthesis.

Animals do not perform cellular respiration.

Plants also perform cellular respiration.

There is nothing incomplete about Andre’s statement.

Question 3

Select one answer.

10 points

Select the incorrect statement regarding respiration and fermentation from the list below.

Respiration produces much more ATP than fermentation

Respiration produces acidic products, fermentation does not.

Both respiration and fermentation use organic molecules.

Respiration uses oxygen, fermentation does not.

Question 4

Select one answer.

10 points

Energy is harvested from which reaction to produce ATP?

Carbon dioxide and water → sugar and oxygen.

Sugar and oxygen → carbon dioxide and water.

Question 5

Select one answer.

10 points

What is the source of energy for photosynthesis?

O2

Light

CO2

Water

Sugar

Question 6

Select one answer.

10 points

One way to explain how cellular respiration and photosynthesis relate to each other is to say that:

Plant cells use the oxygen produced by respiration for photosynthesis.

The oxygen produced by photosynthesis, once released to the environment, is the oxygen able to be used as the electron acceptors for cellular respiration.

Cellular respiration is a series of reduction reactions while photosynthesis is a series of oxidation reactions.

The two processes are not related.

The use of oxygen by plants contributes to the greenhouse effect.

Question 7

Select one answer.

Question 8

Select one answer.

10 points

All of the following statements is true of photosynthesis, EXCEPT:

Releases CO2

Glucose is produced.

Water is required

Question 9

Select one answer.

Which of the following is an anabolic pathway?

photosynthesis

cellular respiration

fermentation

all of these processes

Question 10

Select one answer.

10 points

Plant leaves contain many different pigments. What is the purpose of having multiple pigments?

Capture light for photosynthesis at different wavelengths.

To absorb light that may harm the photosynthetic machinery.

To give leaves different colors in the fall.
