A person who has very toned muscles likely has.... A.extra nerve cells. B. lots of digestive enzymes. C.tightly packed myofibrils. D.lots of smooth E.R.
We can confirm that a person with very toned muscles likely has tightly packed myofibrils.
What are 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.

Explain the difference between rotating and revolving. Then, describe the rotation and revolution/orbit of Earth.
Answer in at least four complete sentences. (o-o¬)
Be sure to check your grammar and spelling.
You can use the sentence starters and hints below to help you answer the questions:
When the Earth rotates, it is ________________________________.
When the Earth completes one revolution, it is __________________________.
*Hints for your last two sentences: Think about the shape of Earth's orbit, how long one rotation and one revolution take, etc.
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).

A box is pushed a distance of 4 meters with a force of 10 N. How much work has been done?
6 units of work
40 units of work
14 units of work
No work has been done
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.
How to calculate work done.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.

Why is nuclear fusion currently not feasible as a source of electrical energy?
Answer:
Fusion is generally impossible because the strongly repellent electrostatic forces between the positively charged nuclei prevent them from colliding and fusing. One of the key reasons we haven't been able to realize the promise of fusion is because its energy requirements are outrageously large. High-energy neutrons are produced during fusion reactions, although they are not radioactive in and of themselves. They do, however, have such a strong influence on the reactor's walls.

Which describes the chromosome theory of inheritance?
Which one below will end up being expressed in the protein?
a) Intron
b) Exon
c) Transcription factor
d) Terminator
e) Promoter
Exons are the DNA fragments that get to be transcripted and translated into proteins. Option b) Exons end up being expressed in the protein.
What are introns and exons?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.
Introns are non-encoding sequences that produce interruptions in a eukaryotic gene. Exons are the encoding sequences. Exons are the nucleotidic sequences that do codify proteins.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
