Macroevolution refers to evolutionary changes that

a. occur in multicellular organisms.
b. produce new species and groups of species.
c. occur over long periods of time.
d. cause changes in allele frequencies.
e. occur in large mammals.

Expert Solution & Answer

Summary Introduction

Introduction: Macroevolution takes place at the level above the species. The evolutionary changes that occur at a large scale constitute macroevolution.

Answer to Problem 1TY

Correct answer: The result of macroevolution is an alteration in the species or group of species. Hence, the correct answer is option b.

Explanation of Solution

Reason for correct answer:

The large scale changes result in the production of new species or a group of species. Such changes are a part of macroevolution. The events are a landmark in the evolutionary history of any species or genus.

Option b. is given as “produce new species and groups of species”.

In contrast to microevolution that causes changes in the genes or nucleotides, macroevolution causes the changes in the phenotype resulting in new species and group of species. Hence, the correct answer is option b.

Reasons for the incorrect answer:

Option a. is given as, “occur in multicellular organisms”.

Macroevolution can take place in multicellular as well as a unicellular organism. It can also occur in both prokaryotic and eukaryotic organisms. Hence, option a. is incorrect.

Option c. is given as, “occur over long periods of time”.

The changes in macroevolution do not necessarily take place in longer periods of time. Hence, option c. is incorrect.

Option d. is given as, “cause changes in allele frequencies”.

The change in the allelic frequencies results in microevolution and not macroevolution. Hence, option d. is incorrect.

Option e. is given as, “occur in large mammals”.

The process of macroevolution can take place in smaller as well as higher organism. Hence, option e. is incorrect.

Hence, the options a., c., d., and e. are incorrect.

Conclusion

Macroevolution is the process that occurs on a larger scale and results in the phenotypic changes of the organism. This cause the origin and development of new type of species or group of species.

The diagram below illustrates a quorum sensing pathway from Staphylococcus aureus. Please answer the following questions. 1. Autoinduction is part of the quorum sensing system. Which promoter (P2 or P3) is critical for autoinduction? 2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe: a) What molecule do you recommend for the trial. Why? b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for? 3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale. 4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density. Briefly explain your rationale. Mutation 1 Mutation 2

There is currently a H5N1 cattle outbreak in North America. According to the CDC on Feb 26*: "A multistate outbreak of HPAI A(H5N1) bird flu in dairy cows was first reported on March 25, 2024. This is the first time that these bird flu viruses had been found in cows. In the United States, since 2022, USDA has reported HPAI A(H5N1) virus detections in more than 200 mammals." List and describe two mechanisms that could lead to this H5N1 influenza strain evolving to spread in human: Mechanisms 1: Mechanisms 2: For the mutations to results in a human epidered they would need to change how the virus interacts with the human host. In the case of mutations that may promote an epidemic, provide an example for: a protein that might incur a mutation: how the mutation would change interactions with cells in the respiratory tract (name the receptor on human cells) List two phenotypic consequence from this mutation that would increase human risk

You have a bacterial strain with the CMU operon: a) As shown in the image below, the cmu operon encodes a peptide (Pep1), as well as a kinase and regulator corresponding to a two-component system. The cmu operon is activated when Pep 1 is added to the growth media. Pep1 is a peptide that when added extracellularly leads to activation of the Cmu operon. Pep1 cmu-kinase cmu-regulator You also have these genetic components in other strains: b) An alternative sigma factor, with a promoter activated by the cmu-regulator, that control a series of multiple operons that together encode a transformasome (cellular machinery for transformation). c) the gene cl (a repressor). d) the promoter X, which includes a cl binding site (and in the absence of cl is active). e) the gene gp (encoding a green fluorescence protein).
