Answer:
Chambers
Explanation:
Oxygen-rich blood travels from the lungs to the left atrium, then on to the left ventricle, which pumps it to the rest of the body. The heart pumps blood to the lungs and to all the body's tissues through a sequence of highly organized contractions of the four chambers.
Hi there!
In the experiment we can identify the variables to determine if the result of the experiment is sound.
Dependent variable - Growth of plants
Independent variable(s) - Medium of watering, being talked to and not talked to
In an experiment you want to have 1 independent variable to determine if that 1 variable is influencing the dependent variable. Because there are two independent variables in this experiment, it is impossible to tell which one caused the plants that were talked to to grow more. As a result, the correct answer would be...
B. Talking to plants may or may not help plants grow faster because the amount of water given was likely different for each group.
The answer is : b. Theoretically, noise pollution could be so great that it could kill a person. Noise pollution affect our sense of hearing... leading to hearing loss. It also disturb our sleep which could lead to fatigue. Long-term noise above a certain level can have a harmful influence on our health. Research shows that road traffic and aircraft noise increase the risk of high blood pressure. Noise pollution also affects wildlife, where animals depend wholly on their hearing for hunting.
