Explanation -
Bilateral symmetry is a body plan of a life form, according to which the organism can be divided into two equal halves (right and left half) only when cut through central axis/midline of the body (also called saggital plane).
Example of bilaterally symmetrical organisms- insects like coackroach, butterfly.
Thus, option C) is the right answer.

answer is A. Limited resources will
result in stiff competition among
individuals in the population. This will
result in differential
survival across the population because only
the individuals that are able to outcompete
the others will be able to reproduce and pass their genes to the next
generation. This, therefore, will change the allelic
frequency of the <span>population.</span></span>
Cerebrospinal Fluid
Produced by the choroid plexuses of the brain, the cerebral spinal fluid is contained in the subarachnoid cavity and spinal canal. It is reabsorbed by the arachnoid granulations.
Besides acting as a cushion for the CNS, the cerebral spinal fluid plays a critical part in the immunology of the central nervous system, blood flow in the CNS and autoregulation.
The combined mass of rock 1 and 2 = 19.28 + 25.3
= 44.58
Difference between rock 3 and combined rocks
= 46.3 - 44.58
= 1.72 grams
therefore, the third rock was 1.72 grams greater than the combined mass of the other two rocks.
Answer:
Hail.
Precipitation is also known as rainfall and it is important as a way of balancing and regulating the earths atmospheric conditions. Precipitation could involve rainfall, snow or hail.
Hail is usually accompanied by a storm which produces precipitation in the form of ice particles. This happens when the dew point is below freezing which results in the formation of ice crystals.
