PLEASE HELP!! in the process of translation, the ribosome is the site where---
a. free floating amino acids are picked up by tRNA
b. information from DNA is copied to RNA
c. DNA strands are separated and copied
d. amino acid chains are assembled from information in the mRNA
Answer:
d. amino acid chains are assembled from information in the mRNA
Explanation:
The ribosome is the site where amino acid chains are assembled from information in the mRNA (Option d).
During gene transcription, a sequence of DNA called gene is used as a template to create a messenger RNA (mRNA).Subsequently, this mRNA travels to the ribosome to be used as a template for the creation of a protein by the process of translation.The ribosome is the site where successive amino acids are added to the growing polypeptide according to the order of triplets of nucleotides or 'codons' in the mRNA sequence.In conclusion, the ribosome is the site where amino acid chains are assembled from information in the mRNA (Option d).

Although the liver and the pancreas are not part of the digestive tract, they are important to the process of digestion because: a. Secretions they produce help to digest food b. They absorb nutrients into the bloodstream c. They eliminate wastes from the body d. All of the above
Answer:
The correct answer is - d. all of the above.
Explanation:
The liver and pancreas are not part of the digestive tract but they play a very major role in the process of digestion. The liver and pancreas both produce and secretes the enzymes and bile to breakdown the food into nutrients. Bile digests the fat while enzymes of the pancreas break down protein, carbohydrates, and fats.
The liver helps in absorbing the fats and some vitamins and minerals to the bloodstream from the nutrient from digested food. They also help in the removal of toxins and wastes from the digested food or the waste products of breaking down into nutrients through the feces or filtered from the blood by the kidneys.

a.a decrease in pressure
b.one object bumping into another
c.molecules becoming electrically charged
d. a vibration in material causing a vibration in an adjacent area
Answer:
the answer is d
Explanation:
When we hear something, we are sensing the vibrations in the air. The number of vibrations per second is known as the frequency, measured in Hertz (1 Hz = 1 vibration per second).
A scientist is using a species of green algae to study electron transport chain in photosynthesis. He uses a laser to inactivate all of chlorophyll A in the algae, but leaves chlorophyll B intact (case 1). In a separate experiment, the scientist applies a chemical to the algae that inhibits PS I but does not affect PS II (case 2).
Answer:
The scientist done wrong by inactivating chlorophyll A and PS I.
Explanation:
The scientist done wrong by inactivate chlorophyll A and PS I. If he wants to study electron transport chain in photosynthesis, he needs chlorophyll A and PS I for that because the central role of chlorophyll A is to donate electron in the electron transport chain while on the other hand, the primary function of the photosystem I is the NADPH synthesis, where it receives the electrons for PS II.

how to write a narrative story?
Answer:
Start with action or dialogue.
Ask a question or set of questions.
Describe the setting so readers can imagine it.
Give background information that will interest readers.
Introduce yourself to readers in a surprising way.
Explanation:
Answer:
Narrative essays/stories are often anecdotal, experiential, and personal—allowing students to express themselves in a creative and, quite often, moving ways. So, in short, it's an essay about your life with details, events, etc.
Explanation:
Narrative essays/stories should include:
an introduction, plot, characters, setting, climax, and conclusion.must have a purpose; think of this as the thesis of your story.the essay should be written from a clear point of view; essays to be written from the standpoint of the author (you); however, this is not the sole perspective to be considered. Creativity in narrative essays oftentimes manifests itself in the form of authorial perspective. narrative essays are effective when the language is carefully, particularly, and artfully chosen. Use specific language to evoke specific emotions and senses in the reader. the use of the first person pronoun ‘I’ is welcomed; though it is welcomed it is not necessary—nor should it be overused for lack of clearer diction.have a clear introduction that sets the tone for the remainder of the essay. Do not leave the reader guessing about the purpose of your narrative; you are in control of the essay, so guide it where you desire (just make sure your audience can follow your lead).I hope that this helps you! I know it was a lot to read, but it's worth it. Have a nice night! :D

Answer:
i wish i could help
Explanation:
iwe have that
x + (2x + 40) + (3x – 50) = 15,002
Reorder the terms:
(x+2x+3x)+(40-50)=15,002
Combine like terms:
x+2x+3x=6x
40-50=-10
6x-10=15,002
adds +10 both sides
6x-10+10=15,002+10
Combine like terms:
-10+10=0
15,002+10=15,012
6x=15,012
we have that
x + (2x + 40) + (3x – 50) = 15,002
Reorder the terms:
(x+2x+3x)+(40-50)=15,002
Combine like terms:
x+2x+3x=6x
40-50=-10
6x-10=15,002
adds +10 both sides
6x-10+10=15,002+10
Combine like terms:
-10+10=0
15,002+10=15,012
6x=15,012
we have that
x + (2x + 40) + (3x – 50) = 15,002
Reorder the terms:
(x+2x+3x)+(40-50)=15,002
Combine like terms:
x+2x+3x=6x
40-50=-10
6x-10=15,002
adds +10 both sides
6x-10+10=15,002+10
Combine like terms:
-10+10=0
15,002+10=15,012
6x=15,012
we have that
x + (2x + 40) + (3x – 50) = 15,002
Reorder the terms:
(x+2x+3x)+(40-50)=15,002
Combine like terms:
x+2x+3x=6x
40-50=-10
6x-10=15,002
adds +10 both sides
6x-10+10=15,002+10
Combine like terms:
-10+10=0
15,002+10=15,012

7 A student who was training for a cross country race jogged for 2.0 hours and covered a
distance of 14.0 kilometers. What was the average speed of the student?
A
28.0 km/hr
B
7.0 km/hr
С
12.0 km/hr
D
0.14 km/hr
Answer:
7.0 km/hr
Explanation:
A student who was training for a cross country race jogged for 2.0 hours and covered a distance of 14.0 kilometers. The average speed is 7.0 km/hr. Hence option B is correct.
What is training?Training is defined as the process of educating or training your staff on a certain task in order to increase their performance or expertise. There are three main goals of training from the perspective of the individual employee: Increase the person's awareness level. Boost a person's proficiency in one or more of their areas of specialization. increase the drive for someone to do their work successfully.
Average speed is defined as the entire distance that an object has gone in a given amount of time.
It can be expressed as
Speed = Distance / time
Speed = 14.0 km / 2.0 h
Speed = 7.0 km / hr.
Thus, a student who was training for a cross country race jogged for 2.0 hours and covered a distance of 14.0 kilometers. The average speed is 7.0 km/hr. Hence option B is correct.
