New answer needed***

Understanding basic safety procedures used in the biology laboratory. This assignment will also introduce the scientific method and metric system, and will explore properties of water that are essential to life.

Apply critical thinking to answer the following:

1. How would it affect organisms living in cold climates if oil or alcohol were their main body fluid?
2. How do you think the cohesive nature of water relates to its evaporation?
3. Describe in detail an experiment you could conduct to test whether another substance could replace water.

Expert Solution

Answer1 - Oil is highly nonpolar in nature whereas water is highly polar If our main body fluid turns to oil our body cells could not sustain as (ECF) extracellular fluid and intracellular fluid (ICF)which is the cytoplasm of cells are both polar in nature whereas cell membranes are nonpolar in nature so if a nonpolar substance present in ECF and ICF, the cell membrane couldn't sustain and would rupture immediately on the other case if alcohol is main body fluid our body it is slightly smaller so not much difference will be created between the polarity of the cell membrane and ECF, ICF.

Answer 2- Cohesiveness in the water molecules is by the bonding of hydrogen bonds which creates surface tension , and it does not allow the water droplets to separate from each other creating adhesion force between them and pull water droplets towards each other. This property of Cohesion and adhesion do not allow water molecules to separate and evaporator easily.

Answer3 -

Whatever created life on this planet intended water as one integral/essential part for the sustenance of life - WATER as it has always been known!

it is irreplaceable yet we can conduct solvent test to see to polarity of different substances and see witch substance has polarity similar to water

This assignment asks you to demonstrate your understanding of Safety and Health as it relates to the workplace. Create a Word document (.doc or docx) that offers some alternatives for dealing with an active shooter in the workplace. Be sure to list 2-3 actions which can be done to save lives. When, in your opinion, are guns appropriate at the workplace, or not? Do you have strong feelings (positive or negative) about either method? This document should be 2-3 pages...

Description The purpose of this assignment is to demonstrate understanding of basic alterations in vision and hearing. Compose a short (1.5 – 2.5 page) essay explaining one common alteration in vision and one common alteration in hearing. You should briefly describe the pathophysiologic changes, prevalence, manifestations, and treatment for each. You should also explain the mechanism that the specific treatment uses to return a normal functioning state. You may select a disease process from the book, but will need to...

Basic understanding of genetic heredity. DNA code must be understood but molecular details are not needed. Relation between genes, evolution, and natural selection. The distinction between learned behavioral adaptations and innate behavioral adaptations is important. In this context, what we have meant by “3 sources of knowledge in behavior” is crucial. Basics of behavior genetics and the notion of the heritability estimates. Gene-environment interactions are quite important as well.

Describe your understanding of the basic economic problem, or the “economizing problem.” In your answer, consider today’s Western standard of living with access to fresh water, abundant food, and spacious housing. Compare this to the standard of living at the turn of the previous century (1899-1900). What are the differences? In light of Principle 8, “A country’s standard of living depends on its ability to produce goods and services” (Chapter 1, Section 1-3a), explain how each of the following categories...
