Answer:
As a cell prepares to divide, it must make a copy of each of its chromosomes. The two copies of a chromosome are called sister chromatids.
Explain why tongue rolling ability is a discontinuous variation
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.
What is Tongue rolling ability?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.

Researchers used DNA sequencing techniques to find similarities of Hox genes in roundworms, arthropods, mollusks, echinoderms, cephalochordates, and vertebrates. What did they find out about these genes? Select all that apply. A. Hox genes provide information about evolutionary relationships. B. Similarities among Hox genes suggest that they all arose from a single ancestral gene that duplicated many times. C. Hox genes are regulatory genes that determine body plans of animals. D. Only some animals that have been tested have Hox genes, suggesting that Hox genes have no function and only evolved recently.
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.

You bend your arms at the elbow and forcefully press your palms into each other. Your hands do not move and the muscles of your upper arms
do not shorten, but tension greatly increases in them. This muscle contraction is described as being
Answer:
isometric contraction
Explanation:
Isometric contraction is a class of contraction where the muscle maintains a constant length as tension is produced, thereby the length of the muscles does not change during this process. Isometric contractions are performed without joint motion. They are appropriate for the rehabilitation of musculotendinous traumas due the muscle maintains a static position and contraction intensity can be controlled. This type of contraction is common for the muscles in the hands and arms.

calories has he added to his diet?
710 kcals
630 kcals
490 kcals
280 kcals
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.
