Answer:
Animal cells would not have the materials needed to produce energy in cellular respiration.
Explanation:
Answer:
In the Northern Hemisphere, ecosystems wake up in the spring, taking in carbon dioxide and exhaling oxygen as they sprout leaves — and a fleet of Earth-observing satellites tracks the spread of the newly green vegetation.
Meanwhile, in the oceans, microscopic plants drift through the sunlit surface waters and bloom into billions of carbon dioxide-absorbing organisms — and light-detecting instruments on satellites map the swirls of their color.
Satellites have measured the Arctic getting greener, as shrubs expand their range and thrive in warmer temperatures. Observations from space help determine agricultural production globally, and are used in famine early warning detection. As ocean waters warm, satellites have detected a shift in phytoplankton populations across the planet's five great ocean basins — the expansion of "biological deserts" where little life thrives. And as concentrations of carbon dioxide in the atmosphere continue to rise and warm the climate, NASA's global understanding of plant life will play a critical role in monitoring carbon as it moves through the Earth system.

The main dietary factor associated with elevated blood cholesterol is saturated fat.
<h3>
What about saturated fat?</h3>
- Because they increase the amount of LDL cholesterol in our blood, saturated fats, sometimes known as "bad fats," increase the risk of cardiovascular disorders (including heart disease and stroke).
- Cholesterol that is circulated in the blood.
- The majority of this cholesterol is produced by the body, however some is also absorbed from the meals you eat.
- Even if they include fat, foods derived from plants never contain cholesterol.
- Only foods from animals do. Low density lipoproteins are able to transport cholesterol.
- Dietary fat, particularly saturated and trans fats, may increase LDL and total cholesterol levels in the blood.
- Blood cholesterol levels may be lowered by substituting polyunsaturated and monounsaturated fats, particularly olive and canola oil, for some saturated fats.
- When we consume too much saturated fat, the receptors stop functioning as effectively, and blood cholesterol levels rise.
