Explanation:
2 things that plants can produce that animals cannot is both food and oxygen.
Burning of fossil fuels that release sulphur and nitrogen compounds into the air is identified as the major cause of acid rain in the united states.
<h3>What are the causes of acid rain?</h3>
- Acid Rain is created when sulphate and nitrogen oxides from the atmosphere react with rainwater and fall as a result.
- Sulphur and nitrogen particles that mix with the wet elements of rain are the main causes in the production of acid rain.
- Due to air pollutants, notably the excessive levels of sulphur and nitrogen released by machinery and industrial operations, acid rain is made up of water droplets that are extremely acidic.
- The emissions that are released from industries are man-made causes.
- The natural causes, such as lightning strikes in the atmosphere that release nitrogen oxides and volcanic eruptions that release sulphur oxide.
The complete question is :
What have the scientific studies identified as the major cause of acid rain in the United States?
a )chemicals still in the atmosphere from the asteroid collision with the earth
b) excess solar radiation due to the depletion of the ozone layer
c) volcanic ash in the air
d) burning of fossil fuels that release sulphur and nitrogen compounds into the air

Answer:Spectroscopy helps astronomers to determine the composition, temperature, density, and motion of an object.
Infrared spectroscopy helps to identify the atoms and molecules in the object.
The red shift or blue shift (Doppler Effect) in a spectral line tells how fast the object is receding from Earth or coming toward it.
The Doppler shift enables astronomers to discover extrasolar planets.
As a planet orbits its star, the star is alternately moving away from or toward us.
Astronomers can use the Doppler shifts to calculate the speed of the star and the mass of the planet that is tugging on it.
Explanation:
The pleural cavity is the thin fluid-filled space between the two pulmonary pleurae (known as visceral and parietal) of each lung. A pleura is a serous membrane which folds back onto itself to form a two-layered membranouspleural sac. The outer pleura (parietal pleura) is attached to the chest wall, but is separated from it by the endothoracic fascia. The inner pleura (visceral pleura) covers the lungs and adjoining structures, including blood vessels, bronchi and nerves. The pleural cavity can be viewed as a potential space because the two pleurae adhere to each other (through the thin film of serous liquid) under all normal conditions.
i think its D but i'm not 100% sure
