Answer:

The first and second hominids have a more recent common ancestor than the first and third hominids.

Explanation:

The similarity in DNA can definitely reveal us about common ancestry but it does not guarantee that the two species must be mating and reproducing. The best example to support this statement is that humans and chimpanzees  share a common ancestor and both have so much similarity in their DNA. The DNA of humans and chimpanzees is around 99% similar but still humans and chimpanzees cannot mate to produce off springs. Several attempts have been made in past to obtain fertile off springs by mating humans and chimpanzees but so far their mating has not produced any fertile off spring.

Answer:

(B) Similarities among Hox genes suggest that they all arose from a single ancestral gene that duplicated many times.

Explanation:

Hox genes are arranged in clusters and their order on the chromosome is the same as the order in which they are expressed along the body during development.

The given options must be in the calories in approximate value.

Answer:

The best answer is - 710 calories approximately.

Explanation:

One ounce of the beer provides 12 calories and as it is given that Jonathan drinks five 12 ounce beers throughout the day then,

12 ounce = 12 × 12 × 5

=  144 × 5

= 720 calories

Thus,  it is found out that he has added 710 calories approximately to his diet additional.

Since tongue rolling ability is determined by a single gene with two separate alleles—the dominant allele, which codes for tongue rolling ability, and the recessive allele, which codes for tongue rolling incapacity—tongue rolling ability is a discontinuous variation.

The hereditary characteristic known as tongue rolling ability controls whether or not a person can roll their tongue into a tube shape. This characteristic is frequently used as an illustration of a straightforward hereditary trait with discontinuous variation since there are only two possible outcomes: either a person rolls their tongue or they do not.

Either a person has the recessive allele, which prevents them from rolling their tongue, or they have the dominant allele, which allows them to roll their tongue. There is no intermediate or in-between trait, and the presence or absence of the dominant allele is a distinct, plainly observable phenotype.

Therefore, the capacity for tongue rolling is an illustration of a discontinuous variation.

Answer:

C - Mutations are the only source of genetic variation for asexual reproduction

Mutations are the only source of genetic variation for asexual reproduction.

A mutation is a change in the DNA sequence of an organism. Mutations can result from errors in DNA replication during cell division, exposure to mutagens or a viral infection.

Germline mutations (that occur in eggs and sperm) can be passed on to offspring, while somatic mutations (that occur in body cells) are not passed on.

A mutation is never so advantageous in real life that it makes someone a superhero or does anything strange like give them wings. There are numerous explanations for why mutations typically don't have significant effects.

Therefore, Mutations are the only source of genetic variation for asexual reproduction.

Answer:

The correct answer is -

The genotype of offspring - 1:2:1 (YY:Yy:yy)

The phenotype of offspring - 3:1 (dominant trait: recessive trait)

Explanation:

In this question, it is stated that there is a cross between Yy and Yy. By the genotype of the parents, we can say that Y is dominant for a particular trait and y is recessive and the parents are in the heterozygous condition in this cross. The gametes these parents will produce are - Y and y and Y and y

then the cross of Yy and Yy would be -

      Y      y

Y    YY    Yy

y     Yy    yy

Offspring from this cross are YY, Yy, Yy, and yy which means the genotypic ratio is - 1:2:1 and the phenotypic ratio is - 3:1 as three out of four are dominant.

Answer:

The PH at which an enzyme will function best is;

In the optimal range

Explanation:

Every enzyme has an optimal pH value which is specific for the enzyme, and where their maximum activity of the  enzyme is observed, which is known as its optimal pH

When the enzyme is placed in a different pH, the enzyme activity is observed to be diminishing until the effect of the enzyme stops

This is so because, as the pH of the environment changes, the shape of the active site on the substrate to which the enzyme binds to have an effect changes and the enzyme is no longer able to effectively interact with the substrate

The enzymes in the stomach work best in the acidic environment of the stomach and have an optimal pH of 2, while the enzymes of the small intestine have an optimal pH of 7.5
