Summary Introduction
To determine:
The reason for spreading of potato blight in Ireland quickly and the way by which
Introduction:
The diploid multicellular stage in life cycle of plant is termed as sporophyte. When a haploid egg fuses with a haploid sperm, a zygote is formed. Sporophyte develops from the zygote and has two sets of chromosomes.
Expert Solution & Answer
Explanation of Solution
In 1840s, in the Ireland potato was a popular crop. In rural Ireland people were dependent totally on potatoes for daily food. From 185-1847, potato blight named fungal disease completely ruined the potato crops. Blight produced spores on potato plant leaves. These spores could be transmitted by wind and water. Through these transmitters, spores could enter soil and infect potato tubers. Due to this many millions of people died due to starvation in the Ireland.
Spraying disease resistant chemicals in small amount on crops can prevent them from fungal infection. By minimizing the contact between water ad foliage can also prevent fungal infection, as any infection takes place in humid or wet area. Watering the soil at soil level early in the day is also good. By this, foliage dries quickly.

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.

- 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 riskarrow_forwardYou 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.

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).
