Why is the word "translation" used for protein production? Protein production is the process of:________.
Answers
Answer:
Answered below
Explanation:
Translation is the actual process of protein synthesis and it occurs in the cytoplasmic ribosomes. Protein production or protein synthesis is the process in which cells make proteins. This process occurs in two stages called transcription and translation.
Transcription involves the transfer of genetic information in the deoxyribonucleic acid to the messenger ribonucleic acid in the nucleus through the process of initiation, elongation and termination. The messenger ribonucleic acid is processed and carries the information to a ribosome in the cytoplasm where protein production takes place through translation.
During translation, the instructions in the messenger ribonucleic acid are read and transfer ribonucleic acids ensure the correct sequencing of amino acids in the ribosomes. The rRNA is involved in the bonding of the base pairs to produce a polypeptide chain which is a unit of a finished protein.
Answer:
The word translation is use for protein production because it is the process of translating RNA sequence of bases.and thereby producing sequence of encoded amino acids from the RNA
sequence which is a consist of polypeptide chain during protein synthesis.
Protein production is the process of synthesising protein.
Explanation:
Translation is a process that occur in the RIBOSOMES or endoplasmic recticulum after transcription of RNA and it is the process where genetic code in the messenger RNA is decided or translated to a sequence of amino acid.
Protein synthesis is processs by which cells produce protein which occur in the RIBOSOMES.
Protein synthesis occurs in two stages which are Transcription and translation.
Transcription is the process whereby genetic instructions or materials in DNA are transmitted to messenger RNA in the nucleus.

geothermal converts kinetic energy to electrical energy, by heating up an object, and then the heated objects will create molecules and atoms that will move really, really fast and the cycle will continue while the geothermal creates energy and stores the energy in the movement of the object
( plz mark me as brainliest, that would be most appreciated! )
They both convert kinetic energy to electrical energy.
What is Kinetic energy?By using wind to drive the fan, wind power transfers kinetic energy to electrical energy.
By heating an object, geothermal transforms kinetic energy into electrical energy. The heated objects then produce molecules and atoms that move incredibly quickly, and the cycle continues as the geothermal creates energy and stores the energy in the movement of the object.
Kinetic energy is the energy that an object has as a result of motion. As long as an object is moving at a steady speed, its kinetic energy won't change.

Explanation:
Anode heel effect is the lower field intensity that occur at the anode compare to the cathode which is as a result of lower x-ray emissions from the target material at angles perpendicular to the electron beam.

Consider that it takes, on average, 24 hours (or 1,440 minutes) for each onion root tip cell to complete the cell cycle. You can calculate the amount of time spent in each phase of the cell cycle form the percentage of cells in that stage.
Percentage of cells in stage X 1,440 minutes = ________ minutes of cell cycle spent in stage.
Answers
Answer: Hope this helps you :)
To calculate the time spent on each stage of the cell cycle, we need to know the total time required to complete the cycle and the percentage of cells that are in that stage. Then, take the product of both values.
--------------------
According to the statement,
The percentage of cells in a stage X 1,440 minutes = Time in minutes of cell cycle spent in the stage.
So, to know how much time is spent in each stage of the cell cycle, we need to know the time it takes for a cell to complete the whole cell cycle, and how many cells there are.
We already know that it takes, on average, 24 hours (or 1,440 minutes) for each onion root tip cell to complete the cell cycle.
Now, we should count the number of cells. Since I do not have a slide, I will assume that there are at least 50 cells, and from that 50 cells present in the slide, 25 are in the same stage. Let us say that the 25 cells are in the prophase.
So, considering a total number of 50 cells (100%), 25 cells equals 50% of the total.
Now, we know that
Time required to complete the cell cycle = 1440 minutesPercentage of cells in the prophase = 50%
Minutes spent in prophase = % of cells in prophase x 1440 minutes
Minutes spent in prophase = 50% x 1440 minutes
Minutes spent in prophase = 0.5 x 1440 minutes
Minutes spent in prophase = 720 minutes
According to this example, cells spend 720 minutes of their time in the prophase.
Now, I suggest you count how many cells do you have in your slide, and recognize how many are in each of the stages. Then you will be able to calculate the real-time spent per stage.

The correct answer is - end of cytokinesis.
Explanation:
Cytokinesis :- a procedure that partitions the cytoplasm and plasma layer of a cell, bringing about two indistinguishable cells that contain their own DNA, nucleus, nuclear membrane, and plasma membrane.
During the last phase of the cell cycle, cytokinesis permits the cell to complete the process of isolating, making two cells with indistinguishable duplicates of DNA
The cell squeezes in the equator area with the assistance of a ring of contractile protein filaments. The formed cleavage furrow develops until the two cells squeeze off totally.
Thus, the correct answer is - end of cytokinesis.

a. reflex arc associated with vasomotor fibers
b. reflex arcs involving baroreceptors
c. altering blood volume
d. centers in the medulla oblongata and the pons
Answers
Answer:
c. altering blood volume
Explanation:
The sympathetic nervous system acts to modulate blood pressure during short-term periods by modifying arterial pressure. The catecholamine hormone levels may be associated with an increase in the blood pressure by narrowing the blood vessels. Catecholamines are hormonal neurotransmitters released by the adrenal glands. These hormones derive from the metabolism of tyrosine amino acids and include, among others, adrenaline, noradrenaline and dopamine.

2. Their reverse transciptase has no proofreading capability
3. Their genetic material is RNA.
4. They disrupt the immune response.
The correct answer is because Their reverse transcriptase has no proof reading capability.
Explanation:
Retrovirus is a type of RNA that replicate it's copy and put it in the host cell DNA, there by changing it's genome. Retrovirus mutate at high rate in vivo viral replication. And this mutation in retroviruses may occur at different stages like during proviral transcription by RNA polymerase II, during minus-strand DNA synthesis (RNA template) by viral reverse transcriptase, or during plus-strand DNA synthesis (DNA template) by reverse transcriptase.
Retrovirus exhibit a high mutation rate. Polymerization errors during DNA synthesis by reverse transcriptase, has no proof reading capability, is a major method for generating genetic variation within retroviral populations.

Answers
Answer:
They would be shaped like a hill.
Explanation:
A longitudinal wave with higher energy have greater amplitude. Amplitude is the distance between the crust and trough of the wave. Crust is the upper part of the wave while trough is the lower part of the wave. If the distance between crust and trough of the wave is higher so the amplitude is also greater and we can say that the wave contains high amount of energy and vice versa. The shape of the wave just like a hill.
