Question
Chapter 4.5, Problem 3EQ
Summary Introduction
To determine: The conclusion of the experiment in reference to Figure 4.23 given in the textbook.
Introduction: Initiation of the synthesis of the proteins used for various purposes takes place on the ribosomes present in the cytosol with the help of messenger RNA. The endoplasmic reticulum plays a major role in protein translational along with the synthesis of phospholipids. The two types of the endoplasmic reticulum are rough endoplasmic reticulum and smooth endoplasmic reticulum.

SARS-CoV-2 is expected to be similarly sensitive. Several human coronaviruses can be inactivated by classical disinfectants, including bleach, ethanol, povidone-iodine, chloroxylenol, chlorheximide, and benzalkonium chloride, so we expect similar inactivation with SARS-CoV-2. The virus stability on surfaces…arrow_forwardUnit test Consider the following passage: In the 1960s, bald eagles in the United States were at the brink of extinction. Scientists discovered that this was due to habitat loss, illegal hunting, and the use of the pesticide DDT, which caused the eagles' egg shells to thin and break before chicks were fully developed. As a result of this understanding, DDT was banned in 1972. In addition, the Endangered Species Act, which protected the eagles' habitat and led to captive breeding programs, was passed in 1973. In 2007, bald eagles were taken off the threatened species list, and there are now more than 71,000 breeding pairs in the contiguous United States. Which of the following statements is best illustrated by the information provided in the passage? Choose 1 answer: Before an environmental problem is fully understood, groups of individuals can discuss and brainstorm ideas about how to solve the problem.
