Which chemical compund is formed during photosynthesis ?

Answers

Answer: carbon dioxide / CO2

During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose

·Why does it make sense that blood flow varies throughout different organs

Answers

It is important that blood flow varies throughout different organs because of differences in the metabolic activities of the different organs.

What is the circulatory system?

The circulatory system refers to the system of organs and tissues which are involved in the circulation of blood around the body.

The circulatory system performs the essential function of delivering nutrients to tissues and cells as well as removing metabolic waste from them.

Since the different organs in the body perform specialized functions, some organs are actively involved in metabolic activities, therefore need greater blood flow.

Therefore, blood flow varies throughout different organs because of differences in their metabolic activities.

Old lead pipes are still used in the building.
Asbestos was not removed from the building.
The heating system is releasing carbon monoxide.
Pesticides were used in the building's landscaping.

Answers

Answer:

A

Primitive lead pipes still in use in the construction may be the root of the building's developmental issues. So, the correct option is A.

What are Lead pipes?

Long lead pipes are recognised as the main source of lead in drinking water, lead service lines are the pipes that transport water from the underground water main to homes.

Remember that lead has been used in water pipes for thousands of years. Ancient civilizations picked lead for piping because it could withstand tiny leaks and was pliable enough to form into efficient water-delivery designs.

The development problems with the building may be caused by the outdated lead pipes that are still being used in the construction.

Thus, the correct option is A.

An increased population will result in the improved environmental health of the oceans due to more scientists inventing better technologies.
An increased human population size means that the ocean's resources will be used more efficiently.
As the population goes up, the oceans are more likely to be used as a habitat for humans.
As the population increases, more demands are put on the ocean to support human life.

Answers

Answer:

As the population increases, more demands are put on the ocean to support human life.

Explanation:

Many countries rely on the ocean for transport and as food sources. Over fishing has continuously been a growing problem as more and more fish are required to sustain populations as well as support more gourmet markets. A higher population will also lead to higher trade rates as more materials that aren't available in one country will need to be imported from others.
