Answer:
Answer is B.
nitrogen (78.10%), oxygen (20.90%) - this combination of gases dominate the Earth’s atmosphere.
Explanation:
The atmosphere of earth is a gaseous layer which surrounds the earth. It protects the life on earth by absorbing harmful ultraviolet radiation, reducing temperature extremes, maintaining the existence of liquid water on the earth's surface and warming the surface. The atmosphere consists of many gases including some pollutants and greenhouse gases. Nitrogen is the gas present in the atmosphere most abundantly while Oxygen and Argon take the second and third place. Atmosphere contains approximately 78% of nitrogen , 21% of oxygen and 0.9% of argon. Gases like carbon dioxide, nitrous oxides, methane, ozone and the water vapor constitutes the rest of the atmosphere. Many small particles called aerosols are also there which include dust, spores, pollen, volcanic ash, smoke etc. There are five layers of atmosphere. Troposphere (0 to 12 km) where we live is the lowest layer of earth's atmosphere ,which is closest to the earth's surface contains half of the atmosphere. Here most clouds are found and almost all weather occurs. Stratosphere (12 to 50 km) is the second layer where jet aircraft and weather balloons fly. It contains the ozone layer that absorbs harmful radiation from the sun. Mesosphere (50 to 80 km) is the third highest layer and the coldest part of the atmosphere where most meteors burn up upon entering in to the atmosphere. The fourth layer is thermosphere (80 to 700 km) where the International Space Station orbits earth and the space shuttles flew. Exosphere (700 to 10,000 km) is the outermost layer where the atmosphere merges into outer space. Most of the satellites orbiting earth are found here.
In the given situation, purple color allele is heterozygous and the parents are homozygous.
<h3>What are genotypes?</h3>
The term "genotype" refers to an the genetic makeup of an organism in other words, it describes an organism's entire set of genes.
In a narrower sense, the term can refer to the alleles, or variant forms of a gene, that an organism carries.
In the given situation, purple color allele is heterozygous and the parents are homozygous.
Thus, the answer is heterozygous and homozygous respectively.

Answer:
Initial age of ghost shrimp and water temperature
Explanation:
In an experiment, there are several variables (alterable factors) that determine the outcome of the experiment. A CONTROLLED variable or CONSTANT is a variable that is kept constant or unchanged throughout the experiment. The constant is not changed because it can affect the other variables (outcome) of the experiment.
For this experiment conducted by Mary Beth on the effect of size of the tank on the size of the shrimp after 6months, the constants are INITIAL AGE OF GHOST SHRIMP and WATER TEMPERATURE. This is so because the ghost shrimps of the same initial age must be used to start the experiment, so as to be able to measure the actual effect on the growth. Also, the water in the respective tanks must be the same Temperature so that one experimental group will not be favored over another.
The answer is morph.
This could be caused by genetic polymorphisms
or variation in the effect of the environment
on each genotype. To be classified as such, morphs must occupy the same habitat
at the same time and belong to a panmictic population (one with random mating).
