Nature constantly adjusts the atmospheric carbon level. An increase in the level causes the atmosphere to hold more heat, which causes more water to evaporate from the oceans, which causes increased rain. Rain washes some carbon from the air into the oceans, where it eventually becomes part of the seabed. A decrease in atmospheric carbon causes the atmosphere to hold less heat, which causes decreased evaporation from the oceans, which causes less rain, and thus less carbon is washed into the oceans. Yet some environmentalists worry that burning fossil fuels may raise atmospheric carbon to a dangerous level. It is true that a sustained increase would threaten human life. But the environmentalists should relax—nature will continually adjust the carbon level.

Which one of the following, if true, would most weaken the argument in the passage?

(A) Plant life cannot survive without atmospheric carbon.
(B) It is not clear that breathing excess carbon in the atmosphere will have a negative effect on human life.
(C) Carbon is part of the chemical "blanket" that keeps the Earth warm enough to sustain human life.
(D) Breathing by animals releases almost 30 times as much carbon as does the burning of fossil fuels.
(E) The natural adjustment process, which occurs over millions of years, allows wide fluctuations in the carbon level in the short term.

Answers

Answer 1

Answer: E) The natural adjustment process, which occurs over millions of years, allows wide fluctuations in the carbon level in the short term.

Explanation:

If the natural adjustment process takes millions of years then it nature will not be able to adjust the levels of carbon in the atmosphere fast enough. This means that in the short term, carbon levels will fluctuate widely if more fossil fuels are burnt.

It is therefore necessary that humans reduce how much fossil fuels that burn to ensure that in the short term, situations on earth are manageable while the adjustment process goes on for millions of years.

Ecotourism can provide an incentive for local people to preserve the environment in order to attract more visitors, but sometimes development is done with little planning for long-term environmental impacts. On a small island in the Caribbean, a local group is considering opening a resort for ecotourism. If they wish to build a sustainable and ecofriendly business, what should be the next steps in their plan?
A. Investigate the ecological impacts and gather evidence on which to base their decisions
B. Hire an agent to locate a suitable property and start developing infrastructure
C. Market the development to investors and explain ecotourism to them to raise money for the resort
D. Determine what types of activities the resort will offer and hire staff

Answers

Answer: The next steps in their plan should be to (Investigate the ecological impacts and gather evidence on which to base their decisions). The correct option is A.

Explanation:

ECOTOURISM is defined as the visitation of individuals (tourist) to natural areas that conserve the environment and sustains the well-being of the local people. It has to do with the interaction of the biotic components of the natural environment by tourists. This has the advantage of providing an incentive for the local inhabitants but can cause a long term negative environmental impact of not properly planned.

Conservation of these natural resources improves the quality of lives. It enables the inhabitants to live in a clean and healthy environment (eco-friendly). To set up a tourism center, certain rules and regulations needs to be met in order to avoid endangering both the biotic and abiotic components of the ecosystem. Therefore these local groups should investigate the ecological impacts and gather evidence on which to base their decisions. This would help conclude if a particular selected environment is conducive.

AMP-PNP is a non-hydrolyzable analog of ATP that can bind to proteins in a similar manner as ATP but is no longer hydrolyzed. Predict what would happen to helicase activity if AMP-PNP were added to a DNA replication reaction. Choose one: A. Helicase would function normally, since AMP-PNP is not the same as ATP and would not bind to helicase. B. Helicase would function normally, since AMP-PNP is an analog of ATP and would function in the place of ATP. C. Helicase would function faster than normal, since the AMP-PNP is not hydrolyzed. ATP binding induces conformational changes, but hydrolysis slows DNA unwinding by helicase. D. Helicase would no longer function, since the AMP-PNP is not hydrolyzed. ATP binding and hydrolysis induce the conformational changes that facilitate DNA unwinding by helicase.

Answers

Answer:

The correct answer is - D. Helicase would no longer function, since the AMP-PNP is not hydrolyzed. ATP binding and hydrolysis induce the conformational changes that facilitate DNA unwinding by helicase.

Explanation:

During the replication process, helicase unzips or unwinds the double-stranded DNA. Helicase is a motor protein that uses ATP molecule hydrolysis in order to break the H-bonding between the strands of DNA.

If AMP-PNP added during DNA replication then it will bind to helicase and remains bound to helicase due to fact that it is a nonhydrolyzable ATP analog.

Answers

Answer:

1 - Deforestation

2 - Industrial Fishing (mass fishing; when industries use those big nets to collect a ton of fish. y’know that Finding Nemo scene?

3 - Global Warming

4 - Poaching

5 - Pollution

Explanation:

Deforestation is destructive to our air quality, as well as the homes of wild life. This can and does causes animals to die, and not enough animals for the greater part of the food chain.

Industrial fishing is harmful to entire environments purely by there being a lack of fish for other animals to eat, as well as a large portion of the worlds fish being now absent because of this mass fishing.

Global Warming is caused by harmful gasses being released into our atmosphere, which is harmful for all life on earth when the earth’s temperatures are being raised.

Climate change in general is bad and caused by humans’ negative impact.

Poaching is illegally hunting animals. This leads to [if not already endangered] wild animals being endangered or extinct.

Pollution can go from anything to littering on the street or beach to industries dumping oil into our oceans, which is harmful for our water supply and all ocean wildlife.

B. They are more likely to have harmful mutations.
C. They are more likely to become an invasive species.
D. They are more likely to have some individuals adapted for survival.

Answers

Answer:

D

Explanation:

Looks correct if you go with D

Genetically diverse population make a species more likely to survive a change to the environment because they are more likely to have some individuals adapted for survival. Thus, the correct option will be D.

What are Genetic variations?

Genetic variation is the difference in the DNA molecule among different individuals or the differences between different populations of a species. The multiple sources of genetic variation include changes which could result from mutation and genetic recombination.

Mutations are the ultimate sources of genetic variation in a population, however other mechanisms, such as genetic drift, also contribute to it, as well. The populations which are genetically diverse are more likely to have some individuals adapted for survival.

Therefore, the correct option will be D.
