balloon to various depths and observed the result. Which one of the following best
describes what happed to the balloon as it went deeper?
(a) The balloon got larger because the pressure of the water around it increased
compared with the pressure inside the balloon.
(b) The balloon got larger because the pressure of the water around it decreased
compared with the pressure inside the balloon.
(c) The balloon got smaller because the pressure of the water around it increased
compared with the pressure inside the balloon.
(d) The balloon got smaller because the pressure of the water around it decreased
compared with the pressure inside the balloon.
The balloon got smaller because the pressure of the water around it increased compared with the pressure inside the balloon. Therefore, the correct answer is (C).
As the student submerged the balloon to various depths, the pressure of the water around the balloon increased, which caused the balloon to get smaller. This is because the pressure inside the balloon remained constant, while the pressure outside increased.
The helium inside the balloon would have been compressed by the increased pressure of the water, causing the balloon to decrease in size. This phenomenon can be explained by Boyle's law, which states that the volume of a gas is inversely proportional to the pressure of its surroundings.

Answer:

Explanation:
Houseflys are like Diptera
Final answer:
Houseflies have two wings.
Explanation:
Houseflies, like many other insects, have two wings. These two wings are the primary flight appendages of the housefly and are attached to the thorax, the middle section of the insect's body. The presence of two wings is a characteristic feature of the order Diptera, to which houseflies belong.
The two wings of a housefly are typically transparent and membranous, allowing for flight. In addition to their two wings, houseflies also have two small, club-shaped structures called halteres located behind the wings. Halteres serve as sensory organs and are essential for the housefly's stability and balance during flight.
The presence of two wings and two halteres is a defining characteristic of true flies, which are members of the order Diptera. These wings play a crucial role in the housefly's ability to fly and are an integral part of their anatomy.

The genotype of the mother is XX while the genotype of the father is XY.
A genotype simply means the collection of genes in an individual. It is also referred to as the alleles that are inherited in a particular gene.
In this case, since red-green color blindness is a recessive trait, this implies that it will not be visible in a heterozygous female. Hence, the dominant allele will therefore mask the recessive allele.
Since the father has only one X chromosome, then if the trait was present in that X chromosome, he must have shown the trait because all the alleles in Y chromosome are recessive. In this case, the son has inherited the trait from the mother.
