Use your knowledge of Protein Synthesis, and the provided chart, to identify the
correct Amino Acid sequence from the mRNA strand: AGUUGGUCUGUA
A: serine, tryptophan, serine, valine
B: aspartic acid, valine, leucine, asparagine
C: leucine, histinde, glutamic acid, leucine
D: serine, threonine, arginine, aspartic acid
Answer:
A: serine, tryptophan, serine, valine
Explanation:
Hi there!
Protein Synthesis is the process where proteins are created from DNA.
We are given the mRNA strand AGUUGGUCUGUA, as well as a provided chart
The mRNA strand is created out of nucleotides (each of the letters is one nucleotide in the code), which will code for a specific chain of amino acids, creating a protein.
Each amino acid is made up of 3 nucleotides. This sequence of 3 nucleotides is called a codon.
So we can break up the code into groups of 3, to make identifying the codons easier.
AGU UGG UCU GUA
Now we need to figure out which amino acid each codon codes for. Thankfully, we were given a chart that can help us with that.
The chart is read where the first base is on the left, and is vertical. The second base is in the center, yet is horizontal. The third base is on the right, and is also vertical.
Let's start with the first codon, which is AGU
The first base is A. The second base is G, and the third base is U. So the first amino acid is serine (ser)
The second codon is UGG.
The first base is U, the second base is G, and the third base is G. So the second amino acid is tryptophan (trp)
The third codon is UCU
The first base is U, the second base is C, and the third base is U. So the third amino acid is serine (ser)
The fourth codon is GUA
The first base is G, the second base is U, and the third base is A. So the fourth amino acid is valine (val).
That means the amino acid sequence from the mRNA code is: serine, tryptophan, serine, valine. The answer is A

DNA and RNA are macromolecules made up of units called nucleotides.
What are nucleotides?A nucleotide is the most fundamental element of nucleic acids (RNA and DNA). A sugar molecule (ribose in RNA or deoxyribose in DNA) is bonded to a phosphate group and a nitrogen base to form a nucleotide. Adenine (A), cytosine (C), guanine (G), and thymine (T) are the bases that make up DNA. The base uracil (U) replaces for thymine in RNA. Long chains of nucleotides make up DNA and RNA molecules, which are polymers.
hence nucleic acids like DNA and RNA are made up of nucleotides

D) A thermostat switching on an air conditioner when the temperature gets too hot
Answer:
D) A thermostat switching on an air conditioner when the temperature gets too hot
Explanation:
All other answers choices are negative feedback.
hope this helped!
A thermostat switching on an air conditioner when the temperature gets too hot is an example of positive feedback. Option D is correct.
Positive feedback is a process in which a change in a system causes further changes in the same direction, leading to an ever-increasing effect. In the case of a thermostat, the increase in temperature causes the thermostat to switch on the air conditioner, which cools down the room. This cooling down causes the thermostat to switch off the air conditioner, which then allows the temperature to rise again. This cycle continues until the temperature reaches a desired level.
In negative feedback, a change in a system causes other changes in the opposite direction, leading to a return to the original state. For example, when a herd of buffalo runs away after one of them spots a lion, the other buffalo will also run away, which will reduce the number of buffalo in the herd that are in danger. This will eventually lead to the herd returning to its original state. Option D is correct.

Which of the following best explains why Mars' and Venus' surface temperatures vary, despite both planets having atmospheres that contain mostly carbon dioxide?(1 point)
Venus has a surface of high mountains which absorb heat.
Mars has a surface of red rocks and sand which reflect heat.
Venus has a thick atmosphere which blocks heat from the surface.
Mars has a thin atmosphere that cannot hold much heat.
Mars and Venus are the planets of the solar system and vary in their temperatures. Mars has a thin atmosphere that cannot much amount of heat. Thus, option D is correct.
What is the atmosphere of Mars?Mars has been the fourth planet of the solar system that is also called the red planet due to its red appearance. It has more amount of carbon dioxide than oxygen gas. It comprises various gases and has a thin atmosphere.
The thin atmosphere of Mars unlike Venus cannot hold the heat and transmits it back to space. Venus has a thick atmosphere that traps heat and results in an increased surface temperature. The atmospheric particle of Mars cannot retain heat and hence vary in temperature.
Therefore, option D. Mars has a lower temperature than Venus due to its thin atmosphere.

if your leg was to get cut off where would you feel the pain?
The thigh area will feel much more pain as when leg is cut off , all nerves are together in thighs, so more pain will be there.
Hope it helps you... pls mark brainliest if it helped you
Answer:
The nerve(s) in your leg.
Explanation:
It's not your leg that will hurt but the nerve in your leg. So wherever the leg is cut, the nerves will have to be cut as well, but also after one of your limbs is amputated, you may feel like the limb is still there. That's called phantom sensation. You might feel pain in your limb even though it is physically not there.
