Blood is taken to the lungs to become oxygenated and returned to the heart before being pumped through the body by the blood vessel called arteries.
What are the roles of different types of blood vessel ?Blood vessels are the networks of hollow tubes which involve in the transportation of blood throughout the entire body along with the delivery of nutrients.
The blood vessel Arteries are elastic in nature which transport blood away from the heart Like Pulmonary arteries transport the blood from the heart to the lungs.
Veins are elastic transport blood to the heart. There are four types of veins are pulmonary, systemic, superficial, and deep veins.
Capillaries present within the tissues of the body and transport blood from the arteries to the veins.
Sinusoids a narrow vessels present within the liver, spleen, and bone marrow, deliver blood from larger arteries to veins.

Which pH indicates a basic solution?
1.
1
2.
5
3.
7
4.
12
Answer:
7
A pH value greater than 7 indicates a basic solution. The more the pH value exceeds 7, the more basic is the solution.
7 is the answer.
If the pH is 1, that means the substance is sour or acidic.
If it has a pH of 5, then it is not that acidic.
If something has a pH of 12, then it is almost completely basic.
If something has a pH of 7, then it is basic.

What will most likely happen if the human population continues to grow and carelessly emit gases? (L17.20)
Too many greenhouse gases in the atmosphere may block heat from escaping into space and trap too much heat next to the Earth's surface creating a hole in the ozone layer
Too many greenhouse gases in the atmosphere may block heat from escaping into space and trap too much heat next to the Earth causing earthquakes.
Too many greenhouses gases in the atmosphere may block heat from escaping into space and trap too much heat next to the Earth's surface causing volcanic eruptions.
Too many greenhouse gases in the atmosphere may block heat from escaping into space and trap too much heat next to the Earth's surface causing global warming.
Answer:
I think it would be the goal warming one :)
If the human population continues to grow and emit gases then this may lead to global warming. The green house gases in the atmosphere block heat and hence cause global warming. Thus, the correct option is D.
What is Global warming?Global warming is the change in climate, referring to the long-term increase in the planet's temperature. It is caused by increased concentrations of greenhouse gases in the atmosphere. This is mainly because of human activities such as burning fossil fuels, pollution, and farming.
The greenhouse gases in the atmosphere absorb the heat. They radiate this heat. Some of the heat will leave the Earth, some of it will be absorbed by greenhouse gases, and some of it will get back at the planet's surface. With the increase in the greenhouse gases, heat will stick around, warming the planet.
Further increase in the green house gases lead to melting of glaciers and increased precipitation. This will change the climatic conditions globally.
Therefore, the correct option is D.
