Answer:

1. aa

2. They have similar DNA

Explanation:

1. According to the question 1, wrinkled seeds (A) are dominant over round seeds (a) in pea plants. This means that, based on the law of dominance proposed by Mendel, wrinkled seeds will be expressed over round seeds in a heterozygous state (Aa).

However, since the round seed phenotype is a recessive trait, it will only be expressed when the alleles for round seeds (a) are the same in the gene i.e. aa genotype.

2. Based on the information in question 2, Ricky, who is working on a family tree for his school project, realizes that his close relatives all look similar in the pictures he collected. This is possible because of the SIMILARITY OF THEIR DNA (genetic material). Note that, relatives are connected by the genes that are inherited from one another, hence, they possess a similar DNA, which is the most valid reason for the resemblance.

First off, you should be looking at the whole world, not just the northeastern US. Are other regions warming? Can you provide proof that simply because the northeast received a lot of snow and low temperatures, climate change is not a viable theory?

Explain why the quantum number set (3, 2, 3, -½) is not possible for an electron in an atom.

Doss [256]

I think because there is no such quantum shell as -1/2.

Which of the following is a homogeneous mixture?

Gala2k [10]

Answer:

Water and applesauce are examples of a Homogeneous Mixture

Chicken Noodle Soup and Soil with Water would be examples of a Heterogeneous Mixture.

Explanation:

Homogeneous Mixtures are mixtures that are the same throughout, i.e. it's just one substance. A good example of this is a glass of water, this is because it is all one solution without any other visible different parts that will settle if left alone for a while. The same applies to the applesauce, it is one type of a mixture with nothing else added to it.

Hetergeneous Mixtures on the other hand are different substances added together. The noodles, soup and chicken, three different substances in one mixture. The soil and water mixture also applies, two substances which separate if left alone.
