Explain.

Writing a lab report between 9-10 pages.
Genetic Regulation
purpose: determine what mutations have occurred in the different strains of E.coli. (012, ML 308-225, W575)
β-galactosidase assay will determine which two strains are mutated and which is the wild type
Genetic Regulation – procedure
Mix to resuspend any sediment in your samples.
add 10 drops of toluene in the fume hood. Mix and incubate 15 min at 37oC.
Add 1mL 1% ONPG to each tube. Mix and incubate 15 min at 37oC. ◦ONPG: ortho-nitrophenyl-β-galactopyranoside
◦Cleaved by β-galactosidase – yields yellow compound (ONP)
Genetic Regulation – procedure cont’d
Add 2 mL of 2% K2CO3 (stops reaction). Keep samples in the hood.
Judge the degree of yellow color compared to the control. ◦– (no color )
◦+ ,++,+++,++++ (increasing yellow color intensity)
◦ Report results to TA for class data
Conjugation
We will plate out the cells to determine if either of the plasmids (containing gldA or gldB) restore motility to our gliding motility mutant
Procedure
◦ Scrape cells off mating plate with sterile applicator and box streak* (supplement p. 44) on a PY2 plate with erythromycin and a PY2 plate without antibiotic
◦ Do this for each conjugation plate, use a new applicator for each streak
◦ Incubate at room temperature in a sealed container
At the end of the report answer these questions:
Questions for lab report: 1. Do the results show that expression of -galactosidase is inducible? If so what is the inducer? 2. Is catabolite repression demonstrated by any of the cultures? 3. One of the strains used was wild type, and the other two were mutants. Based on your observation of the phenotypes of each strain, and your knowledge of the lac operon, which two are likely to be the mutants? What gene or region is likely to be mutated in each of these two strains? Explain.

Learning Goal: I’m working on a botany question and need an explanation and answer to help me learn. Pericardium: Heart is covered by double walled pericardium. The outer layer is ‘fibrous pericardium’ and inner layer is ‘serous pericardium’. In between these two layers, there is pericardial fluid. II) Heart wall: It consist of three layers.(1) OuterEpicardium(2)Middle myocardium(3)Inner endocardium. III) External Structure: Human heart has four chambers.(1)Two small upper chambers are called atria Two large lower chambers are called ventricles (3) Atria and ventricles are separated by a deep transverse groove called coronary sulcus (4) Each atrium has small ear lobe like projection calledAuricular appendix. IV) Internal Structure(1) Atria (i) Atria are thin walled blood receiving Chambers. The right one is larger than theLeft Bicuspid valve Chordas tendina Papiliary muscle Left ventricie Columnse carnese INTERNAL STRUCTURE OF THE HEART(i) The two atria are separated by thin inter-atrial septum (iii) Atria and ventricles are separated by a membrane atrio -ventricular septum.(1) Ventricles :(i) These are thick walled blood ‘pumping chambers’. (ii) The two ventricles are separated by an interventricular septum (iii) The wall of the left ventricle is thicker than the right ventricle Mass of this tissue called AVN (atrioventricular node) is seen in the lower left corner of the right atrium. (4) Aortic arches: There are two aortic arches in man. (i) Pulmonary Arch: It arises from the left anterior angle Of the right ventricle. (ii) Systemic Arch: It arises from the left ventricle.
Female Reproductive System consists of 6 parts.Ovaries(1)Ovaries are the primary female sex organs. That produce female gametes (ova) and also several steroid hormones.(1) A pair of ovaries are located one on each side of the lower abdomen.(1) Ovary is connected with the wall of abdominal cavity by a fold of peritoneum called mesovarium.(1)Ovaries are covered by germinal (ovarian) epithelium and tunica albuginea(1) The main body of ovary is called stroma(1) The outer part of stroma is cortex and inner part is Medulla. II)Fallopian tubes:Each fallopian tube extends from the periphery of Each ovary to the uterus. (2)Each fallopian tube has funnel shaped infundibulum. )The edge of infundibulum has finger like folds called fimbriae. Fallopian tube is the site of fertilization Fallopian tube is attached to body wall by mesosalpinx III) Uterus: (1) Uterus is single and is also called womb. (2) It is present between urinary bladder and rectum. (3)The narrow part by which the uterus is connected to vagina is cervix.IV)Vagina: (1)It is a large fibro muscular tube that extends from cervix to vaginal orifice.(2) It is lined by non keratinized stratified squamous epithelium, It is highly vascular.V) Vulva 1)The term vulva or pudendum refers to the external genitals of the female.(2) Vaginal orifice is often covered partially by a membraneCalled hymen which is a mucous membrane. Accessory reproductive glands of female:(a) Bartholin’s glands (b)Skene’s glands (c) Mammary glands

Learning Goal: I’m working on a botany multi-part question and need an explanation and answer to help me learn.Requirements:NO OUTSIDE SOURCES TO ANSWER QUESTIONSSpell CheckFull sentencesInstructions:Use the summary below as well as the small pdf attached about lichens to answer these 7 questions.Summary:Lichens are unusual creatures. Lichen is not a single organism the way most other living things are, but rather it is a combination of two organisms that live together intimately. Most of the lichen is composed of fungal filaments, but living among the filaments are algal cells, usually from a green alga or a cyanobacterium. In many cases, the fungus and the alga which together make the lichen may each be found living in nature without its partner, but many other lichens include a fungus that cannot survive on its own -it has become dependent on its algal partner for survival. In all cases though, the appearance of the fungus in the lichen is quite different from its morphology as a separately growing individual. The true identity of lichens as symbiotic associations of two different organisms was first proposed by Beatrix Potter, who is best remembered for her children’s books about Peter Rabbit. In addition to her books, she spent time studying and drawing lichens. Her illustrations are still appreciated for their detailed and accurate portrayal of these bizarre organisms. In combination, the lichen symbionts produce a growth form that is unlike either fungi or algae growing alone. Three growth forms are easy to recognize:Lichen are very sensitive to air quality, and even slightly increased levels of ozone and sulfur dioxides will reduce their metabolic activity. In fact, each of the three major types of lichen is sensitive to differing concentrations of air pollutants. Fruticose lichen is the most sensitive to air quality. In the cases of highly polluted air or air regularly exposed to pollutants, the fruticose will NOT be present. Likewise, crustose is the most resistant to pollutants. It can often be found in areas with elevated levels of pollutants. Finally, foliose is moderately tolerant of air pollutants. The presence of each of these lichen in varying numbers and concentrations can provide substantial relative indicators of air quality.Questions:
What is a lichen?
What type of symbiotic relationship does a lichen demonstrate?
Approximately what percentage of the earth’s surface do lichens occupy?
Identify two pollutants that lichens are sensitive to.
Relate lichens to air quality.
Lichen are often the first living organisms to appear in a disturbed area. Why would this be the case?
Lichen prefers to grow in direct sunlight even though it is a fungi-like organism. Why do think they prefer this?
