In ancient times, plant and animal remains got buried, compressed, and transformed into fossil fuels like coal. What biogeochemical cycle does the burning of these fossil fuels today affect?

Answers

The biogeochemical cycle that does the burning of the fossil fuels is the gaseous cycle because when fossil fuels are burned, carbon dioxide is created. The burning of fossil fuels produces approximately 21.3 gigatonnes of carbon dioxide each year, and it's believed that natural processes are only able to absorb only half that amount.

Where would you find the scales of birds?a. on their beaks
b. under their feathers
c. on their wings
d. on their feet

Answers

The correct answer is d - on their feet.

The scales found on birds are made of keratin, the same material that forms the beak, claws and spurs.

The scale are mainly found on the toes of the bird and also on the metatarsus. Some may be found a little up the ankle.

The scales of birds were thought to be similar to those found on reptiles and mammals, but research done in recent times has shown they are somehow different.

A biology class wanted to study the effect of different materials on the melting rate of ice. They placed pieces of ice, each with a mass of 10g, onto trays. Group 1 was covered in plastic, group 2 was covered in paper, group 3 was covered in aluminum, and group 4 remained uncovered.Each piece of ice was allowed to melt for 15 minutes. Then final mass of the ice, minus the melted water, was recorded at the end of the experiment.
Which of the following is the control group in this experiment?

Answers

The control variable is a group that serves as a baseline for comparision. The independent variable is not applied or only applied at a baseline level.

The independent variable is the covering of the ice with different materials. Because group 4 wasn't covered, it is the control variable.

The control group in this experiment is group 4, which remained uncovered.

In an experiment, the control group is the group that does not receive any treatment or manipulation. It serves as a baseline for comparison to the other groups. In this case, the control group is not covered with any material, which means it is not subjected to any additional factors that could affect the melting rate of ice.

By comparing the results of the other groups (group 1 covered in plastic, group 2 covered in paper, and group 3 covered in aluminum) to the control group, the researchers can determine the effect of different materials on the melting rate of ice.

I hope this helps you. :)

Explain the gaseous exchange in lungs

Answers

Answer:

Gas exchange is the delivery of oxygen from the lungs to the bloodstream, and the elimination of carbon dioxide from the bloodstream to the lungs. It occurs in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.

Hope it helped u if yes mark me BRAINLIEST!

Tysm!

Answer:

breathing allows the exchange between 2 gases: oxygen and carbon dioxide. Gas exchange occurs in millions of lung alveoli and the capillaries that surround them

Explanation:

A researcher is studying the impact of different community activities on natural resources. Which activity is correctly paired with the level of impact it has on natural resources?

A.little impact when humans exclusively use fossil fuels for power needs
B.great impact when humans use alternative water sources for nondrinking functions
C.little impact when humans plant different types of trees for different uses
D.great impact when humans maintain a diverse diet that includes various protein sources

Answers

Answer: B. great impact when humans use alternative water sources for non drinking functions.

Great impact when humans use alternative water sources for non drinking functions is the correct option because use of alternative water sources can deplete the overall available water for the present as well as for the future generation of the human population. This is against the concept of sustainable development which suggests that natural resources should be used in such a way so that these can meet the needs of the present population as well as that of future generation.

B) Great impact when humans use alternative water sources for nondrinking functions

A factory is emitting large amounts of CFCs into the atmosphere. How might this affect people?

Answers

CFCs stands for Chlorofluorocarbons. These compounds have long lifetimes. Because of its long lifetimes, it will not only affect our atmosphere but will also climbed to the higher spheres of earth, particularly our stratosphere.

The stratosphere is the location of our ozone layer. It protects us from the extreme rays of the sun. Prolonged presence of CFCs in the stratosphere destroys our ozone layer. Thus, weakening the protection from the sun's uv rays. This will affect us because we are subjected to higher risk of the sun's harmful ultraviolet rays which may result to skin cancer and other sun related ailments.

Answer:

Skin Cancer and other diseases caused by our depleting ozone layer
