Answer:
A
Lipids are water soluble fatty acids that are the primary component of cell walls; they regulate water uptake by the cell because they form carbon chains.
B
Lipids are water insoluble fatty acids and the are the primary component of cell walls; they protect the cell and help maintain its shape because they form carbon rings.
C
Carbohydrates like cellulose and chitin are the primary component of cell walls; they repel and prevent excess uptake of water because they form rigid linear carbon chains.
D
Carbohydrates like cellulose and chitin are the primary component of cell walls; they protect the cell and help maintain its shape because they form chains of rigid carbon rings.
<span>Sea breezes and land breezes are similar in that they are both created by changes in temperature near the ground. With a sea breeze, the air over land warms (during daytime), pressure drops, and air accelerates from sea to land in response. With a land breeze, the air over land cools (during nighttime), pressure rises, and air accelerates from land to sea in response.</span>
<em>Answer is B. The fossils in the lower layers are older than the fossils in the upper layers.</em>
Answer:
Your answer should be... Without them, complex organisms cannot perform different functions.
Answer:
True
Explanation:
The temperature can rise as high as 1500 C, the gas molecules are very far apart. This layer is completely cloudless and free of water vapour
