AQA-7402-3-QP-BIOLOGY QUESTION PAPER 3-A LEVEL-19Jun24. A-level BIOLOGY Paper 3 0 1 . 1 In the following passage, each numbered space can be filled with a biological term. Each type of cell has specific molecules on its (1) that identify it. An antibody is a (2) with two (3) binding sites. Antibodies are made and released by (4) cells. Vaccines can provide protection for individuals and populations against disease. The response to a vaccine is an example of (5) immunity. (6) immunity ...

Hershey and Chase performed an experiment in order to determine how bacteriophages infect bacteria. What did they find? The bacteriophage injects DNA into the host cell. This was found because, after centrifugation, the pellet was radioactive The largest difference between a Gram + and Gram - bacterial cell is: The gram + cell has a much thicker peptidoglycan layer Why does a Gram + cell stain blue/purple in a gram stain? The Gram + cell stains blue/purple because crystal violet rem...

Who discovered the first antibiotic? - Alexander Fleming in 1928 What is the leading cause of antibiotic resistance? - Excessive and inappropriate use of antibiotic agents. What are risk factors for having a drug-resistant pathogen? - The leading risk factors include recent use of antibiotics, age younger than 2 or older than 65, day-care center attendance, exposure to young children, multiple medical comorbidities, recent hospitalization, and immunosuppression. How many antibiotic classes...

Bacterial Cell Wall Agents - correct answer Agents Kill when walls are synthesizing Inhibitors of Murein Monomer Synthesis - correct answer Fosfomycin Cyclomerize Bactrian Fosfomycin** - correct answer Effective Against G- bacteria in the urinary Tract (single dose) enters cell via transporters for glycerophosphate or glucose 6 phosphate Resistance is caused by mutation in the transporters excreted unchanged in urine...

Bacteria correct answers any of a group of microscopic organisms that are prokaryotic, i.e., that lack a membrane-bound nucleus and organelles. Bacteria are unicellular (one-celled) and may have spherical (coccus), rod-like (bacillus), or curved (vibrio, spirillum, or spirochete) bodies. Different bacteria inhabit virtually all environments, including soil, water, organic matter, and the bodies of eukaryotes (multicellular animals). Some bacteria are known to be beneficial to humans and the high...

AQA A LEVEL BIOLOGY Paper 1 2024 What is the function of the cell membrane? - ANS To control what enters and leaves the cell, acts as a barrier between the cell and its environment. What structural feature of the cell membrane allows substances to enter/leave? - ANS Partially permeable What is the fluid mosaic model? - ANS States that a membrane is a fluid structure (because phospholipids are constantly moving) with a "mosaic" of various proteins embedded in it Describe t...

MIC 102 Final Exam Questions with Correct Answers What are the different types of microscopy and staining and when are they used? - Answer-Types of microscopy include: light microscopy- used primarily to get an idea of the form of the bacteria, used in combination with staining to get an idea of Gram positive and Gram negative protein. Green fluorescent is used to observe cell occurrences like binary fission and movement of proteins. Electron microscopy is very detailed at getting an idea of ...
