Describe how different enzymes are classified and named.

Species-area relationships were assessed for reptile species on two sets of islands in different regions of the Indian Ocean. The estimated parameters were as follows: Region 1: c=1.6, z=0.25; Region 2: c=1.8, z=0.35. It is expected that 40% of the reptile habitat will be lost to development pressure over the next decade.

In which region do you expect the loss of reptile species to be greatest, and by how much? Show your work and explain your answer. (3 pts)

b) A different group of species is then assessed on islands in the first region, and the estimated parameters for this species group are c=2.5, z=0.29. What can you conclude about:

i) species richness of this group relative to the reptiles in this region? Why? (1 pts)

ii) the range size of this group relative to the reptiles in this region? Why? (1 pts)

As the conservation officer for Region 2, you were the person tasked with determining the species-area relationship of reptiles in the region. Explain how you came up with the estimates of c=1.8 and z=0.35 (3 pts)

Compare and contrast intensive agriculture and prairie agriculture in terms of their effects on the environment.

Parenchyma is one of the most common tissue types. Describe common human use(s) for parenchyma. Which properties of parenchyma make it suitable for human use?

What is meant by the term cluster of differentiation and give its importance in immune response?

Marine Biology Question: What is an Aternative Stable State?

The production of the mature female gametophyte (embryo sac) via the process of megagametogenesis is unique to Angiosperms.

The process of double fertilization is also a defining Angiosperm characteristic. Describe double fertilization that occurs in the mature embryo sac and indicate the results of such fertilization .

And finally, name and describe two advantages that the Angiosperms enjoy over the Gymnosperms (and everyone else) that has allowed them to conquer the plant world! (2@5 marks each).

what purpose does the female gametophyte serve in the gymnosperm seed?

In a thalassemia (blood disease) prevalent in Southeast Asia, the hemoglobin A polypeptide chain is longer than normal, although the mRNA length is unchanged. The normal HbA polypeptide ends with the sequence: – Lys – Tyr – Arg –(C terminus). The mutant version adds 30 amino acids, ending with: – Lys – Tyr – Arg – Gln – (29 more amino acids) –(C terminus). The causative mutation in the HbA gene is most likely:

A. a transition mutation.

B. a transversion mutation.

C. a nonsense mutation.

D. a frameshift mutation.

E. an insertion mutation

Make sure provide the best explanation about your answer by explaining what the question is asking first and then falsify (provide explanation) each of the choices you did not choose. Ultimately, also provide explanation for for the correct choice. Define any key concepts and terms along the way and make diagrams if necessary to provide the best explanation.

As you showed on the last exam, an experiment at U of Arkansas a couple of years ago showed that the genes for CHF and RA are linked by a distance of 10.2 cM in pigs. In order to test the linkage relationship obtained by the U of Arkansas team, a U of Missouri biology team repeated the experiment making exactly the same cross, but using independently obtained pigs.

Healthy pigs: 255

CHF: 40

RA: 44

Both CHF & RA: 261

Total: 600

Conduct a chi2 test to ascertain if there is sufficient grounds for the Missouri team to reject the Arkansas linkage value. Hint: For your expected values, use the linkage estimate provided by the Arkansas researchers to calculate what the Missouri team would have expected in their experiment. Be sure to show how you calculated your X2 value, your d.f., p-value, and conclusion from your test. For expected values use to 1 decimal, for X2 values use to 2 decimals. If you reject the Arkansas hypothesis, propose an alternative explanation
