Answer:

The first blank can be correctly filled up with proteins.

Proteins are complex molecules which play many crucial roles in the body such as structural role (actin, myosin, keratin), movement, metabolism (enzymes), signal transduction, transport, and defense. In addition, they also determine many traits of the body as they are the last result of the gene expression.

The second and third blanks can be correctly filled up by DNA (deoxyribose sugar).

DNA is the genetic material in most of the organisms including humans. It contains all the information or blueprint for the synthesis of proteins which in turn help in determining the traits of a person.

The last blank can be filled up by the gene.

A gene refers to the unit of heredity which is present on the chromosome. It refers to the protein coding region of the DNA.

With independent assortment, the ratio of genotypes in the F2 generation of a cross between true-breeding strains (AA bb x aa BB
MariettaO [177]

Answer:

c. Aa Bb

Explanation:

The parents were pure breeding with genotypes AAbb and aaBB. A cross between AAbb and aaBB would produce AaBb genotypes in F1 progeny. Two F1 strains would be crossed to produce F2 progeny. The F2 progeny would have the genotype ratio= 1:2:1:2:4:2:1:2:1.

Out of all the obtained genotypes in the F2 generation, the proportion of "AaBb" genotype was 4/16. Therefore, "4" in the given ratio represents the genotype "AaBb".

Describe how is an organism's food and habitat related
Brums [2.3K]
As we already know, organism mean's something that is living.
Well, at a habitat there is going to be some animal's or insect's because it's that animal's or insect's habitat. ( They live there.) Well <u>most</u> organism's are food.
( NOTICE I bloldfaced "most", this is because not all organism's are food) Okay, let's go over what we just said. Organism's are living thing's and habitat's are places where organism's live. Now we have to think about this, you stated, Describe how is an <u>organism's food</u> and habitat related. The one thing we have not talked about is, <u>organism's food</u>. Okay, Animal's live in habitat's and so do organism's.
 ( Remember, some <u>organism's eat other organism's</u>) This is how organism's food and habitat are related.

<u>Hope this help's!</u>
<u>Good luck on your </u>
<u>home work! (:</u>

e) The allele for small size is recessive, and the allele for normal size is dominant. The frequency for the normal-size allele
ki77a [65]

Answer:

51.84%

Explanation:

p² + 2pq + q² = 1 and p + q = 1

p = frequency of the dominant allele in the population

q = frequency of the recessive allele in the population

p²  = percentage of homozygous dominant individuals

q²  = percentage of homozygous recessive individuals

2pq = percentage of heterozygous individuals

p = 0.72 => p² = 0.72² = 0.5184

=> Percentage of the rats are normal sized: 51.84%
