We can confirm that a person with very toned muscles likely has tightly packed myofibrils.

These fibers are the protein filaments that cause contractions in the structure of the muscle. Weight training tones muscles by increasing the number of myofibrils in a sarcomere, thus increasing its capacity to produce force.

Therefore, we can confirm that a person with very toned muscles likely has tightly packed myofibrils.

Answer:

DNA is found in the nucleus of each cell.

Explanation:

Answer:

forms a diploid zygote.

Explanation:

Fertilization joins two haploid gametes into a diploid zygote, the first cell of a new organism. The zygote enters G1 of the first cell cycle, and the organism begins to grow and develop through mitosis and cell division.

Differences in function between the wing of a bird and the forelimb of a seal can be explained by natural selection and adaptation to different environments.

Evolution refers to descendence with modification in an organism, which occurs via natural selection.

Natural selection is the differential reproduction and survival of the more adapted organisms in an environment.

An adaptation is a certain feature that allow organisms to survive in particular environmental conditions.

The quantity of work done by the box is equal to 40 units of work.

Given the following data:

Distance = 4 meters.

Force = 10 Newton.

In Science, work done is generally calculated by multiplying force and the vertical distance (displacement) that is covered by an object.

Mathematically, work done is given by the formula:

Work done = force × distance

Substituting the given parameters into the formula, we have;

Work done = 10 × 4

Work done = 40 units of work.

Answer:

Rotation is the spinning of an object in one place. Revolution is the circling of an object in a given orbit (path).

Explanation:

When the earth rotates, it spins on its own axis which is tilted at 23.5 degrees. Thus, we can conclude that the earth rotates on its axis every 24 hours relative to the Sun.

When the Earth completes one revolution around the sun in a fixed orbit in 365.25 days. This means the earth takes approximately 365 days to completely encircle around the sun and return back to its original position.

(The extra .25 day is added every year to make up one full day. Hence, we see a leap year every 4 years).

The black bear has a tendency to proliferate, whereas the polar bear has a tendency to undergo faster extinction because they live in the arctic.

The black bear (Ursus americanus), also known as the baribal, is a North American bear, found from Alaska to northern Mexico. It reaches 2.20 m in length, 1.10 m in height at the withers and 360 kg in weight.

The polar bear (Ursus maritimus) is a solitary mammal that lives in the icy waters of the Arctic Circle region. It is the largest species of bear that lives in places with low temperatures, being much feared by other animals that inhabit the place.

Considered the largest terrestrial carnivore and main symbol of arctic resistance, the polar bear has been suffering from climate change.

Whit this information, we can conclude that the black bear has a tendency to proliferate, whereas the polar bear has a tendency to undergo faster extinction because they live in the arctic.

Explanation:

Exons are the DNA fragments that get to be transcripted and translated into proteins. Option b) Exons end up being expressed in the protein.

Even though more than 70% of the DNA is related to genes, just a part of the genes is translated to proteins. Most genes have DNA segments that are not transcripted or translated intercalated with segments that are translated.

Most of the eukaryotic, multicellular genes contain introns in their sequences, intercalated with exons.

Introns are transcripted to mRNA molecules and get excised before translation by a specific mechanism. This occurs before the mRNA leaves the nucleus. The introns are excised and the exons must splice to form a unique molecule. This process is known as splicing.

Exonic sequences are the fragments that are transcripted and translated into proteins.

The correct option is b). Exons end up being expressed in the protein
