2. Which of the following statements is FALSE regarding the log-kill hypothesis? a. It predicts the 100% eradication of cells after some period of time. b. It is an application of first-order kinetics. c. It predicts that cell counts decrease exponentially with repeated cycles of application. d. It applies to sterilization as well as other fields such as chemotherapy. e. Each cycle of application kills the same fraction (or %) of cells just prior to that cycle.
please atten abc and d there are all subparts of the same question . Please respond asap thank you so much ! I appreciate it.
2. An 84 kg University of Toledo groundskeeper who is spraying a 100 mg/L solution of the insecticide dieldrin (MW = 381; logP = 4.56) on some trees exposes 100 cm“ of his skin to the solution over a 4 hr period. Dieldrin has a half-life of about 6 months, a volume of distribution of about 40 L/kg, and a dermal permeability of about 3 x 10° cm/sec. (a) Estimate the absorption rate during the exposure period assuming the blood concentration is much lower than the skin concentration (i.e., take the blood level to be zero in the skin absorption equation). (b) Estimate how it takes after exposure begins for the groundskeeper's plasma dieldrin levels to reach 1 ng/L. (c) Estimate the maximum plasma dieldrin concentration in ng/L that will occur in this groundskeeper due to this exposure. (d) Estimate how long it will take after exposure ends for the groundskeeper's plasma dieldrin levels to drop back down to 1 ng/L. %3D

A soil sample taken from a hill reveals that soil solution in the top 30 cm of soil contains 900 micromoles Ca/L. Imagine that the grass growing on this hill has a water use efficiency of 400 g H20/g dry matter. Calcium is considered to be sufficient when between 1-2% of the dry matter. Calculate the calcium content in the soil's dry matter and determine if the level is sufficient.
You have just started working in an Urgent Care Clinic as a nurse. Mom brings in her 3 year old little boy, Brandon. Mom states that Brandon has been having fever up to 104F and he isn't eating or drinking anything because he feels very sick to his stomach, not to mention crabby! He's also been pulling a lot at his right ear and sounds congested. At the last well visit with the Pediatrician (about 2 weeks ago), Mom states that Brandon weighed 32 pounds. On exam today, his weight is 12.5 kg. Additionally his eyes are darkened and sunken, his mouth is dry with some white crusting around the lips. His temperature is 39C, other vitals signs are normal. Though he looks ill he appears to be medically stable. The doctor rushes in, quickly exams Brandon, diagnoses him with otitis media and then barks off orders to you that you then need to convey accurately to Mom. The orders include: push fluids, ibuprofen 10mg/kg every 6 hours if temp > 38C, and begin taking a 10-day course of…
