Answer:
plants can convert carbon dioxide and water into carbohydrates and oxygen in a process called photosynthesis. As photosynthesis requires sunlight, this process only happens during the day. ... Oxygen is required to do this.
Answer:
density independent
Explanation:
In Ecology, density independent factors are limiting factors that do not depend on the size of a population to affect such population. Examples of density independent limiting factors are fire outbreak, earthquake and other natural disasters.
According to this question, since density independent factors influence a population irrespective of its density, it will affect a larger population than a smaller population. For example, a fire outbreak will likely burn a large part of the population, if not all.
The answer is ..b .the smallest units of an element ...

Answer: This is true for all parts of the surface of the Earth including the land and the upper parts of the ocean. The four natural resources; soil/rock, air, water, sun; constitute the major components of the physical environment.
Explanation:
Answer:
Each one has two fatty acid chains and the glycerol backbone is bonded to a small polar group.
Explanation:
Phospholipid is a unique form of lipid. The bonding of the glycerol backbone to the polar phosphate group makes phospholipid to have dual solubility unlike general triglycerides.
The polar head is said to be hydrophillic that is <u>water loving,</u> while the two carbon chains that retained lipid features are hydrophobic <u>water hating.</u>
Therefore if a phopholipid is placed in water, in relation to its functions as component of cell membrane, it forms a bi-layer in which the water loving portion hydrophilic head points into the surrounding watery medium, while the hydrophobic layer points inwards far away from the watery medium into the internal cellular layer to form an impermeable barrier to hydrophilic (polar) substances.
This forms the basis of the phospholipd bilayer of the cell membrane. And it controls the permeability of the cell membrane to influx substances into the cells.
