What is the independent and dependent variable of sand sifting.

Biology
1 answer:
Viktor [21]2 years ago

An easy way to think of independent and dependent variables is, when you're conducting an experiment, the independent variable is what you change, and the dependent variable is what changes because of that. You can also think of the independent variable as the cause and the dependent variable as the effect.

What is the DEPENDENT variable in this experiment? (Hint: What depends on the independent variable?)
Nutka1998 [239]
Could you give more information? For the most part, the dependent variable is what you’re recording. For example, if you wanted to see how plants would grow in different conditions, plant height would be the dependent variable. The height DEPENDS on the condition it was grown in. Hope this helps!

Explain what is ecological conservation and conservation of the environment. What can you do to conserve the environment? Why do
den301095 [7]

Answer:

Conservation ecology is the branch of ecology and evolutionary biology that deals with the preservation and management of biodiversity and natural resources. Its goal is to find ways to conserve species, habitats, landscapes, and ecosystems as quickly, as efficiently, and as economically as possible.

-These are some examples of how we can conserve the environment:

Recycle your rubbish and participate in or help organize recycling campaigns.

Avoid littering and participate in or help organize litter clean-ups (here you can link to a website for volunteering or starting your own beach clean-up).

Use less plastic by, for example, carrying a reusable water bottle, saying no to disposable straws and cutlery, avoiding plastic toys, and bringing your own shopping bags (for further ideas on a plastic-free life take a look here).

Swap toys, movies, and books instead of buying new ones.

Donate, recycle, and repair electronic devices (see how here).

Use less water when brushing teeth, taking a shower, or washing the dishes.

Use less electricity by turning off lights and electronic devices when not in use, using energy-saving light bulbs, and hanging clothes to dry.

Use public transport, share a journey with friends (e.g., car-sharing), cycle, or walk when possible.

Use less paper by not printing unnecessary things and reading e-books.

Turn down the air conditioning when it is hot and use fans if you are still hot-they use much less power.

Turn down the heat when it is cold and use sweaters, blankets, and socks to keep warm.

Do not waste food and try to buy food that is grown locally and in season.

Hope this helps:)

Members of the tropical tree genus Ceiba currently grow in the rainforests of the Amazon. A paleontologist discovers several fos
Naya [18.7K]

Complete question:

Members of the tropical tree genus Ceiba currently grow in the rainforests of the Amazon. A paleontologist discovers several fossils that she attributes to this genus in the Pampas region of Argentina. This region is not currently covered with tropical rainforests. She concludes based on these fossils that this region of Argentina was covered with tropical rainforests in the past. This form of reasoning is known as:

A.  

Deduction.

B.  

Induction.

C.  

Abduction.

D.  

A random guess.

Answer:

This form of reasoning is known as Deduction (Option A)

Explanation:

Induction: Might be defined as a process of initiation in something, such as a religion, a new job, a new activity, a new curse, etc.    

Abduction: Refers to the illegal act of taking someone somewhere by obligation or by force, against the person´s will. Also refers to the body´s extremities movement.  

A random guess: Refers to a random conjecture about something, with no basis or fundaments.

Deduction: The fact of answering a question or reaching a conclusion based on evidence or fundaments. Usually after a process of investigation or study, and knowing the facts.

The exposed situation is an example of a deduction made by the researcher. She bases her conclusion on the fact that Pampa´s fossils might be of the same genus as Amazonia´s trees, which means that in Argentina the environmental and climatic conditions were comparable to those in current Amazonia. Also, as a paleontologist, she must know about the biogeographic processes that modeled the earth and living beings. Her conclusions are not random. She has bases and fundaments to conclude that Argentina was once covered with tropical rainforests in the past.
