1 answer:

8 0

A natural experiment <u>reveals correlative links</u>, but a manipulative experiment <u>simulates a causal relationship</u>.

Example of manipulation: The only difference in the amount of water and sunshine each plant receives is the amount of caffeine. Natural experiment example: examining the prevalence of arthritis in individuals who report having frequent joint cracks

Experiment- A procedure done in a controlled environment for the purpose of gathering observations, data, or facts, demonstrating known facts or theories, or testing hypotheses or theories.

Hypotheses- In a scientific setting, a hypothesis (plural: hypotheses) is a tested claim regarding the relationship between two or more variables or a suggested explanation for a phenomena that has been observed.

Which do you think would adapt and survive overtime to a mass extinction? A starfish or an eel?

Harlamova29_29 [7]

Answer:

Starfish

Explanation:

This is an opinion questions, so there really isn't a right or wrong answer. You could just as easily choose Eel. Your task is to pick one and defend your reasoning.

I chose starfish because starfish have a long history of demonstrated adaptability to a wide variety of conditions. Their armored skin protects them from a variety of predators, as does the poison that many of them contain. They have the ability to regrow limbs, and even regrow entire starfish from certain body parts. When it comes time to breed, starfish meet together in groups. Each female releases a few million eggs from the gonads in each of her arms. Each male then releases billions of sperm from each gonad in each of his arms, thus covering the eggs with sperm to fertilize them.

Climate warming trends allow plant and insect species to inhabit larger ranges. True or false?

attashe74 [19]

The right answer is True.

At the global level, climate change will contribute to the disruption of the Earth's natural ecosystems, which could lead to the extinction of wild animal species and plants. It is mainly the impact of climate change on habitat and ecosystems that will dictate the impacts on biodiversity (by expanding them or the opposite).

Climate change will profoundly affect agricultural and forestry production. The effects in terms of production potential will be very variable depending on the regions and plant cover. They can result in an overall tendency for moderate stimulation in temperate climates and for limited warming at 2 ° -3 ° C.

The cities of Portland, Oregon, and Minneapolis, Minnesota, are at about the same latitude, but Minneapolis has much hotter Summ

Igoryamba

Answer:

Option B.

It is because the ocean near Portland moderates the temperature.

Explanation:

The areas that are near to ocean have the moderate temperatures even in the hot seasons.

Portland has the pacific ocean near to it, so the ocean current regulates the temperature there. But Minneapolis lacks ocean near it, so the summer is more hotter in Minneapolis.
Ocean is capable of counteracting the rough distribution of radiation due to solar that reaches the Earth's surface.
