Answer:
Fossilized remains of marine organisms
Answer:
Water
Oxygen
Carbon dioxide
Lipids
Explanation:
The plasma membrane is a lipid bilayer with a hydrophobic core made of nonpolar tails of phospholipids. The plasma membrane allows only uncharged, small and hydrophobic substances to pass through it. Charged particles such as ions, polar molecules such as sucrose can not cross the hydrophobic core of the plasma membrane.
Oxygen and carbon dioxide gases have small sizes and can diffuse through the spaces between the tails of phospholipids of lipid bilayer of the plasma membrane without any transport proteins. Lipids are hydrophobic and therefore, do not need any transport proteins to cross the lipid bilayer. The small water molecules are also free to move through the membrane.
Answer:
The correct answer is "crop rotation".
Explanation:
Crop rotation is the agricultural practice that consist of growing a series of different crops in sequenced seasons using the same soil. This practice helps to replace the lost soil nutrients by changing the soil nutrients consumption among the different crops. The benefits of crop rotation include reducing soil erosion and increasing soil fertility and crop yield.
Either chemical or light, chemical because it’s a chemical reaction or light because it is light dependant
