1. abscisic acid ( is the hormone that regulates survival functions of a plant, such as the opening and closing of stomata)
2. auxins (chemicals produced in plants that are characterized by their ability to induce cell elongation and cell division in stems)

B)Mendelian genes are at specific loci on the chromosome and,in turn, segregate during meiosis.
Answer:
can you shoot it better because it is quite blurry
Answer:
50% green-seed individuals vs. 50% yellow-seed individuals.
Explanation:
Mendel is known as father of genetics. He explained the concept of dominance, the law of segregation and the law of independent assortment while working on pea plant.
Green seed color is recessive and yellow seed color is dominant. A pure green line seed plant (ss) is crossed with heterozygous plant (Ss). The cross is as follows:
Parents ss (green seed) × Ss (Yellow seed)
Gametes s S, s
progeny: Ss, Ss, ss, ss.
Here, Ss is yellow seed and ss is green seed.
50% green-seed individuals vs. 50% yellow-seed individuals are formed after the cross.
Thus, the correct answer is option (a).
Answer:
Please see below
Explanation:
A. Zebra mussels are located in the areas of the United States that they were introduced to but it continues to spread across the US as time progresses.
B. Since the Zebra mussels can attach itself to solid surfaces, boats are no exceptions. They are able to go a few days out of water which gives them enough time to remain attached until a boater takes the vessel to another lake or isolated body of water.
C. Since these are filter feeders they are growing without a natural predator since they are an invasive specie. They feed on the algae in the water and use up almost all of this food supply and makes resources for other native specie (fish) that depend on this food source to die out.
D. Burmese pythons in the Florida everglades are an invasive specie. The prey on endangered species, have no real predator and have voracious feeding habits that affect the numbers in the animal population.
E. Non- native mongoose was introduced on Jamaica to control the snake population. The problem with introducing a non native specie would be that this new organism is also without a natural predator. After the target specie has been eliminated it may try to feed on other animals in the ecosystem as well.
F. Invasive species need to adapt to weather conditions and should be able to hunt/acquire its food in order to survive in its new environment.
