How many combinations of A, C, G, and U exist? Include an equation
Answer:
64
Explanation:
4 ^ 3 because your first nucleotide can be any of the 4, same with your second, and same with the last nucleotide. 4^3 tells you there are 3 different positions that 4 different bases can be placed.
Hope this helps!
There are 64 possible combinations of nucleotides to form a given amino acid.
The genetic code to add an amino acid is the result of a triplet of nucleotides or codons. In consequence, there are 4^3 possible combinations of nucleotides in a codon.This number (64) gives us the number of different codons that can be found in the genetic code.In conclusion, there are 64 possible combinations of nucleotides to form a given amino acid.

Outline what has to occur in the body for a reflex and a voluntary action to occur.
Answer:
For involuntary actions (reflexes) the information is first detected in the sensor and travels along sensory neurons to the spinal cord. Once the action potential reaches the spinal cord, the information is transmitted across the synapse to the motor neuron. for voluntary actions,
movements are commanded by the motor cortex, the zone of the cerebrum located behind the frontal lobe. The motor cortex sends a neural message that moves through the brain stem along the spinal cord and into the neural network to the muscle being commanded.

Explanation:
espero ter ajudado boa noite
A submicroscopic virulent agent that infects animals, plants, bacteria etc. is called viruses. They are capable of copying inside host cells only. Viruses cause many diseases in animals and plants.
The correct discussion is:
Student A believes that viruses are not living organisms.
The student's statement can be explained as:
The virus is not capable of reproducing on its own without a host system. Therefore they cannot fit in the definition of a living organism. They just have a genetic material encapsulated in protein coats and do have defined cell structures, unlike prokaryotes and eukaryotes.Therefore, viruses are not contemplated to be living.

The above observation shows that the mountain chains in Northern Europe and West Africa are part of the Appalachian Mountains as a result of the same age, matching of rocks, etc
A mountain chain simply means a row of high mountain summits or a contiguous ridge of mountains within a larger mountain range.
The theory of plate tectonics establishes a co-relation with these mountain chains by understanding their movements. It was shown that Europe and Africa were part of the same landmass in the past. Due to the gradual movement of plates, both continents move apart.

The lab that tested the water initially determined that the water quality grew worse between 2005 and

If you want to know if your home’s drinking water

Which THREE statements describe how the models of mitosis and meiosis demonstrate genetic continuity?
Chromosomes are divided up evenly during Anaphase (Anaphase I of meiosis), ensuring that the daughter cells will have the correct number to reproduce.
In Interphase the chromosomes have duplicated, indicating that there will be enough genetic material to separate into daughter cells capable of reproduction.
In Prophase (Prophase I and II of meiosis) the spindles form, indicating that the chromosomes will be split evenly, and the daughter cells will receive the appropriate amount of genetic material.
In Metaphase (Metaphase II of meiosis) the chromosomes are lined up properly, indicating that the chromatids will separate evenly and provide the daughter cells with equal amounts of genetic material.
In Telophase (Telophase II of meiosis) the amount of chromatin present is equal to the amount present during Interphase, indicating that the daughter cells will receive the same amount of genetic material as the parent cell.
Answers: A,B,D
Explanation: :I took the test and got this question right .
The three statements that describes how the models of mitosis and meiosis demonstrate genetic continuity are listed and explain below.
In Anaphase, chromosomes line up in the middle of the cell while the spindle fibres pulls them apart.
Therefore the statement below about anaphase is correct.
Chromosomes are divided up evenly during Anaphase (Anaphase I of meiosis), ensuring that the daughter cells will have the correct number to reproduce.In interphase, the synthesis of DNA occurs where the chromosomes replicates forming two identical copies of DNA.
That is, the cell now has 92 chromosomes which is enough DNA for two cells.
Therefore the statement below about interphase is correct.
In Interphase the chromosomes have duplicated, indicating that there will be enough genetic material to separate into daughter cells capable of reproduction.In the prophase, the mitotic apparatus appears; this consists of two centrioles separated by the mitotic spindle which is formed from microtubules.
The formation of these mitotic spindle fibres indicates that the chromosomes will be split evenly.
Therefore the statement below about prophase is correct.
In Prophase (Prophase I and II of meiosis) the spindles form, indicating that the chromosomes will be split evenly, and the daughter cells will receive the appropriate amount of genetic material.Learn more here:

Answer:
Precipitation
Explanation:
If it's the graph that I am thinking of, then it is precipitation. This is where raining occurs in he picture.
The biogeochemical cycle where the water circulates from the atmosphere to the Earth surface in a continuous motion is called the water or hydrological cycle.
The process that occurs at location W is:
Option A. Precipitation
The water cycle can be explained as:
The water cycle has four main components that are evaporation. condensation, precipitation and runoff.When an atmospheric substance falls on the ground in the form of rain, snow hails etc. are called precipitation.When the water from surfaces turns into vapours and moves upwards in the atmosphere is called evaporation.The vapours in clouds turn into water droplets ready to fall as rain or snow is called condensation.Transpiration is a plant function in which surplus water is exhaled from the stomata of the leaf.Therefore, the water cycle shows precipitation.

Answer:
Hope it helps
Explanation:
mark me brainliest and follow me for more answers
Glycolysis and the citric acid cycle both produce carbon dioxide, which is a crucial byproduct (Krebs cycle). This oxidized carbon is a metabolic waste product that must finally be eliminated through transit to the lungs and subsequent exhalation into the environment.
What is the purpose of Krebs cycle?
Pyruvate is converted into three different products by the Krebs cycle: carbon dioxide, a little quantity of ATP, and the reduced molecules NADH and FADH.
Each acetyl group adds two carbon atoms to the citric acid cycle. On each cycle turn, two carbon dioxide molecules are emitted.
However, these do not include the identical carbon atoms that the acetyl group contributed on that turn of the circuit.
Therefore, carbon dioxide is constantly given off during the Krebs cycle.
