B.
Homogeneous means one mixture, so like salt water. It looks like one mixture.
Heterogenous means different mixture. Comparable to a bag of Chex mix. So if the magnet can attract the pieces of Iron, it has to be a separable mixture. Compounds would require a chemical reaction to separate.
Answer:
True
Explanation:
Spinal nerve divides into several branches after passing through its intervertebral foramen. These branches are called rami. A spinal nerve gives off several branches such as anterior ramus, posterior ramus, rami communicantes, and a meningeal branch. The meningeal branch reenters the vertebral cavity through the intervertebral foramen. It serves to supply the vertebrae, vertebral ligaments as well as the blood vessels of the spinal cord, and meninges.
Answer:
B
Explanation:
The answer is B; there cannot be a large population in an ecosystem that only provides a small amount of food; similar to how a family of six cannot live off of the same amount of food that a single person could easily live off of. This concept rules out both A and D, and C is also incorrect because the ecosystem is independent of the population, it is not aware of the amount of organisms living it; so it cannot alter it's resources based off of what organisms live in it.
See below itemized similarities and differences of surface and subsurface waters.
SURFACE WATER
Input: Through precipitation. When precipitation falls, its a runoff when it doesn't seep into the ground.
Output: Rivers or streams
Storage: Watersheds
SUBSURFACE WATER
Input: Precipitation through recharging process.
Output: When atmospheric pressure above ground is lower than subsurface water pressure it flows as rivers, streams and becomes a source of drinking water or irrigation water in farming.
Storage: Acquifers, rock layer that holds water.

02)Only with powerful microscopes are the bacteria visible to the human eyes as they are the smallest among cells.
03)Bacteria are known as the most abundant forms of life.
04)Bacteria live everywhere: on land, in water, in the air, and inside the bodies of other living organisms.
