Which statement best describes what happened as the volume of the cell increased?

2.Which of the following represents a genetic cross between 2 individuals that are each heterozygous for both traits?

wariber [46]

Answer:

A. AaBb x AaBb

Explanation:

The term heterozygous refers to the presence of two different alleles of same gene in an organism. The one allele can be of wild type (original type) and one can be mutated or newly formed.

In the question, two traits are represented by two letters, A and B and alleles as A and a and B and b, respectively. We are asked about a cross involving two traits and two individuals in such a way that both are heterozygous.

If we look at option A, AaBb x AaBb,

we see that one trait A and the other trait B is in heterozygous form (Aa and Bb) in both individuals.

If we look at option B. AABB x AABB

we see that one trait A and the other trait B is in homozygous form form (AA and BB) in both individuals. Homozygous means when the alleles are same for each trait in an individual.

If we look at option C,Aa x Bb

There are not two traits, one trait of one individual and other trait of other individual is being crossed that is not possible.

If we look at option D. AAaa x BBbb

Again, the individuals are homozygous for two traits.

Therefore, A is best option.

Hope it helps!

Which of the following elements is likely to form a ionic bond with potassium

Igoryamba

The element that is likely to form a ionic bond with potassium is Cl (answer A)

<em><u>Explanation</u></em>

Ionic bond - is a bond formed when a metal and a non metal react.

Metal loses electron ( donate electrons) while non metal gains electrons ( accept electrons) to form ionic bond.

potassium is a metal while Chlorine(Cl) is a non metal. They react to form an ionic bond by potassium donating 1 electron while chlorine accept 1 electron.

Because of genetic variation, a species of beetle has two different body colors, red and green. This species exists in a grassy

pshichka [43]

Answer:

1. Green beetles and red beetles exist in the environment.

2. Birds that eat the beetles move into the environment.

3. Red beetles are eaten by birds, but green beetles aren’t eaten.

4. Green beetles pass on their color trait to future offspring.

5. The entire population of beetles eventually becomes green in color.

Explanation:

According to the theory of natural selection, only those species survives which fits closely with their environment. According to the conditions given, there are two genetic variations of the same species based on the color, i.e. green and red. Initially, both red and green are living together in a grassland (green in color). Then, birds enter the same environment because they have food there (beetles). Now, green beetles will take a competitive advantage because of the color and avoid getting eaten by the birds. However, red beetles would be prominent and eaten fast. The green beetles will pass on their genetic variation causing the color to be green in their future offspring and a time will come when there will be on green beetles in the area.
