Alyssa investigates properties of matter. The answer to which question would best

timofeeve [1]

Answer:

This question is incomplete as it lacks options, the options are:

A) What is the radius of each particle of the substance?

B) Does the substance contain more than one type of atom?

C) Was a chemical reaction necessary to create the substance?

D) What is the electrical charge of the particles of the substance?

The answer is B

Explanation:

In chemistry, an element is a substance made up of a single type of atom i.e. only one atom of the same type constitutes an element while a compound is a substance that contains two or more different elements. If a compound contains different elements, it means that a compound will certainly contain more than one type of atom.

According to this question, the best question to ask when Alyssa wants to differentiate between an element and a compound is: DOES THE SUBSTANCE CONTAIN MORE THAN ONE TYPE OF ATOM?

- If the answer is yes, the substance is a COMPOUND

- If the answer is no, the substance is an ELEMENT.

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!
