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:
c
Explanation:
because the boars have nothing to do with the water
Answer:
To survive
Explanation:
Without water, we wouldn't have organisms such as fish. We also need it to break down food molecules or generate energy during the respiration process.
Answer:
photosynthesis
Explanation:
Photosynthesis is the process used by algae, green plants and some types of bacteria to convert solar energy into chemical energy. During photosynthesis, carbon dioxide (CO2) is consumed and oxygen (O2) is released. In the primitive Earth, the photosynthetic marine organisms helped to replace atmospheric CO2 with O2, which was one of the most important gas components in the atmosphere. Moreover, the ozone (O3) is generated when O2 reacts with sunlight. In the stratosphere, this gas (O3) formed a layer that is capable of filtering ultraviolet harmful radiation.
Estuaries, salt marshes and mangrove forests have more variation in salinity than other marine habitats like the ocean and sea floor because of the environment present in these locations. They are considered to be unique ecosystems in semi-sheltered areas near the ocean coastline. These areas often serve as nursing grounds where young marine life is protected during development.
