Answer:
From the given Options, Option C is correct.
the inheritance of the alleles from each parent is completely random but in a population, there may be natural selective pressure from the environment to favor different levels of expression
Explanation:
The evolutionary basis of human skin color stems far back to the genetic mutations involved in skin pigmentation. Although the diversity of skin color is a characteristic trait of humans, These variants and their evolution reveal that the history of skin color is much older than previously thought.
The evolution of various variations in the human skin color is a result of selective forces which is an environmental factor that favors various levels of expression. Thus, the best option that explains the basis of human skin color in terms of evolutionary trend is Option C.

Each chromosome has genes that control wing shape, body color, antenna type, and eye color.
a. True
b. False
Answer:
The correct answer is - True.
Explanation:
In a simplified drosophila or fruit fly genome, Each chromosome of the homologous pair of chromosomes has the genes for the body color, wing shape, antenna type, and eye color, and all are located on the same chromosome.
So on the basis of the explanation given above it is clear that in Drosophila or fruit flies it is true that Each chromosome has genes that control wing shape, body-color, antenna type, and eye color.

CAN FISH SURVIVE ONLY IN WATER WITH DISSOLVED OXYGEN?
Answer:
Oxygen dissolves into water from two sources: the atmosphere and from plants in the water. kills fish from oxygen depletions can range from “partial” to “total”. In a partial kill the dissolved oxygen level gets low enough to suffocate sensitive species and large fish, but many small fish and hardy species survive.

20. Process through which pollutants get increasingly more concentrated each step up the food chain.
bloaccumulation
risk assessment
toxicity
biomagnification
Answer:
bioaccumulation of chemicals is the problem concerning all living organisms. This is the result of dynamic equilibrium between the uptake and elimination. The extent to which bioaccumulation occurs determines the toxic effects which are manifested. In some cases, the mechanisms of protection from certain undesirable substances deposited in special sites, to prevent their participation in the metabolic reactions, have evolved. The knowledge on bioaccumulation enables to assess the risk related with the presence of various chemicals in the environment, food, and at workplace and to present quantitatively the ability to control the use and emissions of chemicals.

Indicate whether the given structure is located in the outer, middle, or inner ear. pharngotympanic tube helicotrema stapedius
Answer:
The pharngotympanic tube is in the middle ear.The helicotrema is in the inner ear.The stapedius is in the middle ear.Explanation:
The ear has three main parts, the outer part, the middle part, and the inner part. The outer part of the ear starts in the auricle, then it continues with the auditory canal, and it finishes with the eardrum. Then we have the middle ear that is separated from the outer one with the eardrum. In this section, it is the pharngotympanic tube, also known as the Eustachian tube. It is a tube that connects the inner ear with the pharynx to regulate internal pressure.
The inner ear has the bony labyrinth and the membranous labyrinth. In this part of the ear, the mechanical signals are transformed into electrical signals. The bony labyrinth has the cochlea, the vestibule, and the semicircular canals. The helicotrema is in the cochlea, and it connects the tympanic duct with the vestibular duct.
The stapedius is a muscle located in the middle ear. Its insertion is in the stapes, a small bone that moves with the vibrations that come from the eardrum to the malleus and the stapes. The stapedius' function is to protect our hearing by reducing the vibrations that enter this part of the ear.

4) What factors influence the circulation of the Earth's atmosphere,
thereby producing our weather?
The uneven heating of the earth's surface is one of the main variables affecting the circulation of the atmosphere globally along with seasonal variations in precipitation and temperature and Earth turning on its axis.
What is weather?The state of the atmosphere is referred to as the weather, and can be described in a number of different ways, including the degree to which it is hot or cold, wet or dry, quiet or stormy, clear or cloudy. The troposphere, the lowest layer of the Earth's atmosphere, is where the majority of meteorological events take place. The stratosphere is the next layer up from the troposphere. The term "weather" is used to describe the temperature, precipitation, and other characteristics of the atmosphere on a day-to-day basis.
Variations in air pressure, temperature, and moisture from one location to another are the primary contributors to a day's weather. These disparities can be attributed to the fact that the angle at which the Sun is positioned at any given location varies with latitude. The vast temperature difference between the polar and tropical air masses is what gives rise to the biggest scale atmospheric circulations.
