Answer:
24.75 years
Explanation:
62.5 is 1/4 of 500, which means that in 99 years it passed through four half-lifes. So, you divide 99 by four and you get that the half-life is 24.75 years. 25 years if it was rounded

Answer:
Gravitational potential energy is greatest at the highest point of a roller coaster and least at the lowest point. Kinetic energy is energy an object has because of its motion and is equal to one-half multiplied by the mass of an object multiplied by its velocity squared (KE = 1/2 mv2).

Answer:
The correct answer is: B) codominance.
Explanation:
<u>Codominance is a type of inheritance pattern that describes the relationship of two variations of the same gene</u>: this means that in an individual, its two alleles manifest in the phenotype.
If a sunflower has both blue AND yellow speckles, it means that the two possible alleles are in a relationship, which makes these alleles CODOMINANT.
Answer:
<em>The correct options are D. dark-colored, small-sized snails and F. dark-colored, large-sized snails</em>
Explanation:
Evolutionary studies show that those organisms are able to survive and reproduce which are better adapted to live in an environment. Gradually, the organisms that are better adapted to live in an environment increase in number and those that are not better adapted will decrease in population.
As Avian snail kites feed on light- colored apple snails and Avian limpkins feed on medium- sized apple snails, this means that these species are not better as they can be easily captured by their predators.
The dark colored, small- sized snails and dark- colored, large- sized snails will be better adapted to live in the environment as they will not attract the predators. Hence, they will survive and reproduce.
