The genotype AaBbCcDd has 4 genes that are heterozygous and can produce 24 different types of gametes.
What about genotype?Gene pool as a whole is characterized by the term "genotype," which broadly refers to an organism's genetic make-up.The phrase can also be used to describe to the alleles, or different forms of a gene, that an organism carries in a more specific meaning. In contrast, AS and SS shouldn't even consider getting married because there is a good probability that they will have a child who has sickle cell disease. Additionally, there is no way to avoid producing a child with sickle cell disease, so SS and SS must not be married.A genotype is a numerical representation of the type of variant found at a particular locus (i.e., region) in the genome.As an example, the letters BB, Bb, and bb could be used to indicate a specific gene variant.Despite the possibility of random spontaneous mutations, genotype typically does not vary from one environment to another. The same genotype, however, might result in a variety of phenotypes.Learn more about genotype here:

In genetics, codominance refers to a kind of inheritance inside which two variants (alleles) with same gene are activated separately to produce distinct features in a person. Codominance may be seen in spotted cows and plants with petals of two distinct hues.
Codominance can also be seen in less obvious features such as type of blood. Both the A and B blood type alleles can be produced simultaneously at the same time, producing in type AB blood. Codominance, as distinguished to partial domination, occurs when both parents' traits are manifested in the same child organism.

what role did the adaptations of seed and pollen play in the development and expansion of seed plants?
Seeds and pollen allowed plants to breed in absence of water. This allowed them to enlarge their range onto dry land and to survive drought situations.
Both seeds and pollen distinguish among seed plants and seedless vascular plant life. these revolutionary structures allowed seed flowers to reduce or do away with their dependence on water for gamete fertilization and embryo improvement, and to overcome dry land. Flora are capable of disperse their gametes over long distances via the evolution of seeds that allow them to breed independently.
Many terrestrial diversifications have contributed to the achievement of seed plant life. these adaptations regarding seed-decreased gametophyte manufacturing heterosporous ovules and pollen supplied seed plant life with new possibilities to deal with ground situations inclusive of drought and UV exposure.

GOOD LUCK :)
Answer:
1. "Atmospheric humidity is usually measured with a psychrometer and can be described in several ways. The dew-point temperature and the absolute humidity represent the actual moisture in the air, while the relative humidity indicates the degree of saturation at a given temperature."
2. "The dew point is the temperature to which air must be cooled to become saturated with water vapor."
3. "When air has reached the dew-point temperature at a particular pressure, the water vapor in the air is in equilibrium with liquid water, meaning water vapor is condensing at the same rate at which liquid water is evaporating."
4.
"The state or process that occurs when no more of something can be absorbed, combined with, or added. When the dew point equals the air temperature, the air is saturated and the relative humidity is %100.
5. "It is a common misconception that changes in temperature will affect the dewpoint. It is important to remember that dewpoint is independent of the ambient temperature. Only changes in pressure or the actual amount of water vapour present will affect the dewpoint."
6. "When the dew point equals the air temperature, the air is saturated and the relative humidity is %100."
7.
8. "Relative humidity (RH) (expressed as a percent) also measures water vapor, but RELATIVE to the temperature of the air. In other words, it is a measure of the actual amount of water vapor in the air compared to the total amount of vapor that can exist in the air at its current temperature."
9. "The term relative humidity (RH) expresses the relationship between the moisture content of air at a certain temperature and the moisture content of moisture-saturated air at the same temperature. It is given as a percentage from 0 to 100. 100% RH means that the saturation with moisture, the dew point is reached."
10. "The lower the temperature of air the less capacity it has to hold moisture in a vapor state."
11. "Warm air can possess more water vapor (moisture) than cold air, so with the same amount of absolute/specific humidity, air will have a HIGHER relative humidity if the air is cooler, and a LOWER relative humidity if the air is warmer."

The process which happens when ATP is abundant is the process of gluconeogenesis and glycogen synthesis.
Gluconeogenesis is the process of synthesis of glucose from non carbohydrate sources, the most important raw materials being pyruvic acid or oxaloacetate and dihydroxyacetone phosphate. When the intake of carbs from food is insufficient for the needs of the body, the body will turn glucose into energy to meet the needs of the body.
Glycogen synthesis: is the process of glycogen formation from sugar. When there is an increase in blood sugar, the insulin hormone will facilitate the glucose in the blood to store in the liver and muscle cells as energy reserve.
