I'm not sure what you mean by "compartments", but the cardiovascular system consists of the heart, blood vessels, and approximately 5 liters of blood.
Option are not provided in the question. The complete question is:
Which activity would help decrease the greatest carbon-releasing activity in US homes?
limiting time in hot showers
wearing layers of clothing
turning off lights when leaving a room
unplugging electronics when not in use
Answer:
wearing layers of clothing
Explaination:
Increasing carbon emission in environment is one of the major cause of global warming and climate change. There are several human activities that contribute to increament in carbon-releasing such as burning of fossil fuels, industrial manufacturing and deforestation et-cetra.
Wearing layers of clothes can decrease the greatest carbon-releasing activity in US homes because the weather of US is cold and people use a lot of fossil fuel to make their surrounding warm. Wearing layered clothes will help US people to feel warm and reduce the burning of fossil fuel which is major contributor to carbon emission.
Hence, The correct option is wearing layers of clothing.
Homeostatic there must be a mechanism to control water changes
Answer:
The chloroplast
Explanation:
The choloroplast takes in nutriets (sunlight) and converts it into energy for the plant
Answer:
c. a proton gradient set up across the thylakoid membrane
Explanation:
During the photosynthesis (this also occurs in cellular respiration in mitochondria), hydrogen ions (H+) move across the thylakoid membrane down their electrochemical gradient (from the area of their higher concentration to the area with hydrogen ions lower concentration). An ion gradient can be used for the production of ATP.
