Answer:

Meadow Plants Would Decrease And Rabbits Would Decrease.

Explanation:

As we see in the food chain, the me adow grass is what the rabbits consume. If there is a wildfire, the grass would burn, leaving the rabbits with bothing to eat, causing a decrease in their population.

Hope this helps!

What would be the expected effect on plants if the atmospheric CO2 concentration was doubled? What would be the expected effect

Elis [28]

Answer:

C3 plants would have faster growth rates; C4 plants would be minimally affected.

Explanation:

C3 and C4 pathways are the variations of dark reactions of photosynthesis present in green plants. The photosynthetic efficiency of C3 plants is reduced due to the affinity of RuBisCo enzyme for oxygen which in turn leads to the futile pathway of photorespiration. RuBisCo enzyme catalyzes the rate-limiting reaction of the C3 pathway. On the other hand, the C4 plants concentrate CO2 around RuBisCo in their bundle sheath cells of leaves to minimize photorespiration and exhibit higher rates of photosynthesis.

Increased levels of atmospheric CO2 would reduce the photorespiration in C3 plants and would allow them to fix CO2 efficiently due to the increased concentration of CO2 around the enzyme RuBisCo. The increased photosynthetic efficiency would help these plants to exhibit faster growth rates.

However, the photosynthetic rate of C4 plants is not limited by CO2 concentration as they themselves reduce photorespiration by spatial separation of primary carboxylation in mesophyll cell and CO2 fixation in bundle sheath cells. Hence, increased CO2 levels in the atmosphere would not have any impact on their photosynthetic rate and growth.

What are the advantages and disadvantages of using renewable and nonrenewable energy resources? Use evidence from the lesson and

timofeeve [1]

Answer:

The answer to this question is given below in this explanation section.

Explanation:

Advantages of renewable energy resources:

Using renewable energy over fossil fuels has a number of advantages.Here are some of the top benefits of growing green.

Renewable energy won't run out:

Renewable energy technologies use resource straight from the environment to generate power.These energy sources include sunshine,wind,tides,and biomass,to name some of the more popular options.

Maintenance requirements are lower:

In most cases,renewable energy technologies require less overall maintenance than generators that use traditional fuel sources.This is because generating technology like solar panels and wind.

Renewables save money:

Using renewable energy can help you save money long term.Not only will you save on maintenance costs,but on operating cost as well.When you are using a technology but generates power from from the sun wind team natural processes.

Renewable energy has numerous health and environmental benefits:

Renewable energy resources emit little to no greenhouse gases or pollutants into the air.

Renewable lower reliance on foreign energy sources:

With renewable energy technologies you can produce energy locally.The more renewable energy you are using for power needs.

Disadvantages of renewable energy:

Higher upfront cost:

You can save money by using renewable energy the technologies are typically more expensive upfront by traditional energy generators.

Intermittency:

Through renewable energy resources are available around the world many of these resources are not available year around.

Storage capabilities:

Because of this intermittency of some renewable energy resources there a high need of energy storage.

Geographic limitations:

The united states has a diverse geography with varying climates topographies vegetations and more.

Ivan

Answer:

A.OSHA

Explanation:

The complete question is as follows:

Who mandates that employers of emergency responders must take certain measures to protect employees who are likely to be exposed to blood and other body fluids?

A.OSHA

B.UNICEF

C.CDC

D.USMLE

OSHA is the short form for the Occupational Safety and Health Administration which is an agency of the United States Department of Labor located in Washington D.C, USA.
The agency works to set and enforce standards for safe and healthy working environment for both men and women who work in private and public sectors.
The employers of OSHA have the responsibility to provide a safe workplace and ensure that no serious health hazards take place in the same.
Therefore the employers of emergency responders are mandated by OSHA to take measures to protect employees that are exposed to body fluids and blood.
