. Two students are discussing natural selection in bacteria and how it can relate to antibiotic resistance in
bacteria.
Bernadette states that when antibiotics are used, bacteria can respond by developing traits to help them
defeat the antibiotic, which then may increase their fitness.
Dominique states that there is already a variety of traits among the bacteria. Bacteria that have traits that
allow them to survive the antibiotic and reproduce may have higher fitness.

If a molecule is too large to pass through a cell membrane, it will need to use a

Answers

Cells use exocytosis to secrete molecules too large to pass through the cell membrane by any other mechanism. Some molecules, such as carbon dioxide and oxygen, can diffuse across the plasma membrane directly, but others need help to cross its hydrophobic core. In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers.

While dry cleaners are small businesses, they generate relatively large volumes of hazardous substances. EPA estimates the average dry cleaner generates 660 gallons of hazardous wastes a year. Unlike petroleum contamination which may break down over time by naturally-occurring bacteria in the environment, the chlorinated solvents that are used by dry cleaners are resistant to biodegradation. As a result, groundwater contamination from dry cleaners has a greater potential to migrate off-site which can be problematic since dry cleaners are often located within proximity to residential neighborhoods. Indeed, a 2002 Florida study found that dry cleaner contamination had migrated off-site at 57 percent of the contaminated sites. Due to these types of environmental hazards when commercial land is sold require a Phase 1 Environmental Assessment according to the Comprehensive Environmental Response, Compensation and Liability Act. Why would the type of monitoring required as part Phase 1 Environmental Assessments be important if a dry cleaner was being sold?


A) The monitoring will indicate any environmental damage done that should be remediated prior to selling the land.


B) This type of monitoring will allow the government to only sell land to businesses that have environmentally friendly practices.


C) The monitoring prevents the land from being resold to any dry cleaning businesses which can be damaging to the environment.


D) The monitoring will allow the government to determine which type of business is better for the environment so dangerous businesses can be closed.

Answers

Answer:B) This type of monitoring will allow the government to only sell land to businesses that have environmentally friendly practices.

Explanation: because will allow the government to only sell land to businesses that have environmentally friendly practices.

Observe the given figures carefully and answer the following questions.(a) The amount of CO2 be the highest in which jar. Why?(b) The amount of CO2 be the lowest in which one and why?

Answers

Answer:

a) Jar C, b) Jar A

Explanation:

a) The amount of CO2 is the highest in jar C because it only contains CO2-producing organisms: mice. A plant in the same jar, like in jar B, would counteract this CO2 production by using it to produce oxygen, which would balance it out.

b) Jar A has the lowest amount of CO2 because the plant is by itself only producing oxygen. There is no life form in jar b that produces CO2.

Answers

Answer:

This blank space in this question is COMPETE

Explanation:

This question is describing natural selection, which is the theory proposed by Charles Darwin where he stated that organisms that are better suited for an environment will survive and reproduce better than others.

In the environment, resources such as food, water, mate etc are limited, hence, organisms must COMPETE for the available ones. In this case, organisms that are better adapted will triumph over others. Therefore, it is certain that not all organism that are born can be supported by the environment because organisms COMPETE for resources.
