It is TRUE that each lung is fed oxygen by a separate bronchus.
Humans respire through the use of lungs. Each human being possess two lungs and each lung has its own bronchi. The bronchi serve as the path for the movement of air from the nose / mouth to the alveoli in the lungs. The alveoli are surrounded by blood vessels and the oxygen from the outside enter the blood through the thin capillary wall of the blood vessels while the carbon dioxide is released to the outside through the same medium.
Answer:
1 Other Threats. Coral reefs are also being degraded by many other factors. The list of problems can seem endless: overfishing, fishing using cyanide and dynamite, pollution from sewage and agriculture, massive outbreaks of predatory starfish, invasive species, and sedimentation from poor land use practices.

Explanation:
d) collect gas produced with a gas syringe
-compare volumes at different temperatures
-incubate mixture and different temperatures
6:1 Ratio means that it is easier to move the materials. SA = ^2, while V = ^3. That means volume increases at a faster rate than surface area. That is why is it optimal to have a high SA:V ratio, which is why cells are so small.
Hello Gangt181, The current increase of carbon dioxide in the atmosphere is as a result
of human activities that began in the late 1700s. This period sparked
the beginning of the Industrial Revolution and this is when we began to
use fossil fuels. The burning of fossil fuels coupled with widespread
global deforestation has led to a rise in CO2. Excess carbon dioxide in
the oceans causes it to become more acidic. This acidity will affect
marine species with shells like mussels and lobsters.
