Answer:
In the mRNA sequence AUGGUGCAUGUC the maximum number of amino acids that can be encoded is 4 (option A).
Explanation:
Messenger RNA (mRNA) has a sequence of nitrogenous bases produced by the transcription of a DNA strand. This sequence of bases is organized in triplets or codons —made up of 3 nitrogenous bases— that can encode an amino acid, or mark the beginning or end —STOP codon—of protein synthesis.
From the sequence:
AUGGUGCAUGUC
Four codons are obtained, each of which encodes a different amino acid:
Codons: AUG-GUG-CAU-GUC
Amino acids: Met - Val - His - Val
Methionine Valine Histidina and Valine are the four amino acids encoded by the 12 nucleotide sequence of the mRNA.
what properties of ocean water determine its ability to scatter or absorb light

a.
decreases the present and future risk to human properties
b.
increases both the present and future risk to human properties
c.
decreases the present but increases the future risk
d.
increases the present but decreases the future risk
Please select the best answer from the choices provided
A
B
C
D
Answer: a. decreases the present and future risk to human properties
Explanation:
Properties along the coasts can be in danger when high tides come in. This can however be mitigated by walls protecting those properties as it would take a significantly high tide (flood proportion) to scale those walls and come in and damage the property.
These walls therefore not only decrease the present risk to human properties but if maintained, decrease the future risks as well.

In what stage of sleep do you experience a high level of motor cortex activity (the part of the brain involved in the planning, control, and execution of voluntary movements) that is blocked by the brainstem, leaving you more-or-less temporarily paralyzed?
Answer: REM
Explanation:
There are four stages, 3 of them are non-REM stages, (or NREM) and obviously, the other is the REM stage.
We are looking for a stage where your body becomes "paralyzed".
This would be the REM sleep stage.
This is the stage where most of your dreams happen, and that is why your body is more-or-less paralyzed, so you do not move while dreaming.
There are other characteristics, like irregular (and faster) breathing and an increase in blood pressure and heart rate.
explain why adding protons to the treated mitochondria increase ATP synthesis?
Answer:
Because protons are no longer being used to power the ATP synthase, the proton gradient is not dissipated; the increasingly steep proton gradient makes it increasingly difficult for the electron-transport proteins to pump protons out of the matrix, and electron transport quickly stops.
Explanation:
Hope this helped!
Mitochondria are the power-house of the cell, which are primarily involved in the synthesis of Adenosine Triphosphate (ATP). The synthesis of ATP is mediated by the proton pump and electron transport chain.
The protons generate the gradient, which is produced by the proton-pumping during the electron transport chain. The increase in the mitochondrial ATP production is mediated by the activated SIRT1 and AMPK.
The protons then flow down the concentration gradient into the matrix through ATP synthetase, a membrane protein.
The gradient will cause the spinning and catalyze the conversion of ADP into ATP.
Therefore, the metabolic machinery of the ATP synthesis in the mitochondria will be increased due to the proton pump.

Suppose the DNA sequence GCT ATA TCG was changed to GCTАТТ TCG. How would the products of translation, the amino acids, be affected ?
Answer:
The outcome of a frameshift mutation is complete alteration of the amino acid sequence of a protein. This alteration occurs during translation because ribosomes read the mRNA strand in terms of codons, or groups of three nucleotides. ... Each word itself has a separate meaning, as each codons represents one amino acid.
Explanation:
hope it helps.
have a wonderful day!
In the given DNA sequence GCT ATA TCG, the second codon is changed from ATA to АТТ.
This change would affect the products of translation, which are the amino acids. To determine the amino acids, we need to refer to the genetic code, which translates each codon into a specific amino acid. The codon ATA corresponds to the amino acid isoleucine (I), while the codon АТТ also corresponds to isoleucine (I).
Since both codons, ATA and АТТ, code for the same amino acid (isoleucine), the change in the second codon would not affect the amino acids produced during translation. Therefore, the products of translation, the amino acids, would remain unaffected by this change.

1. Explain how forces of attraction and repulsion exist within an atom.
Answer:
Oppositely charged particles attract each other, while like particles repel one another. Electrons are kept in the orbit around the nucleus by the electromagnetic force, because the nucleus in the center of the atom is positively charged and attracts the negatively charged electrons.
Explanation:
Answer:
1. Electrons surrounding a nucleus are attracted to the protons within it because electrons and protons have opposite charges. Electrons closest to the nucleus are attracted with such a force that they can’t escape from the atom. These electrons tend to shield the protons from electrons that are farther away because electrons have the same charge and repel each other. Electrons that are farther away have less attraction to the protons within the nucleus and are more likely to be detached from the atom.
2. Electrons can be transferred from atoms of one body to atoms of another body through friction. This can occur when one body is rubbed against another or when a liquid flows across a solid. In either case, one body may be given a positive charge while the other body is given a negative charge of the same magnitude. Both charges are developed at the same time. Electrons can also be transferred from one body to another when a charged body comes into contact with an uncharged body. The electrons move in the direction that will equalize the charges; thus, the uncharged body will be given the same charge as the charged body.
3. Free electrons move from points of negative charge to points of positive charge. When these electrons move freely from one point to another with little resistance, the material they’re traveling through is said to be a conductor. Conductors have a large number of free electrons. Insulators, on the other hand, have very few free electrons and offer great resistance to the movement of these electrons. Electric charges produced on one end of a body composed of insulating materials will most likely not spread throughout the body. In a conductor, this charge would spread throughout the entire body. Metals are generally conductors; oils, rubber, air, porcelain, and plastics are good insulators.
4.
Lightning is produced by the rapid transfer of free electrons when one of the following conditions exist: One part of a cloud is positively charged and a neighboring part of the same cloud is negatively charged. A positively charged cloud comes near a negatively charged cloud. A cloud with either a positive charge or a negative charge comes near the earth.Explanation:

Answer:
1. Archaea
2. Binomial nomenclature
3. Eubacteria
4. Eukaryote
5. Morphology
6. Prokaryote
7. Reproductive isolation
Explanation:
Archaea are microorganisms without a cell nucleus (i.e., prokaryotes), which were originally classified as Archaebacteria. Nowadays, procaryotic organisms are classified into two domains: Archea (Archaebacteria) and Bacteria (Eubacteria). These organisms are characterized by the lack of membrane-bound organelles. On the other hand, the domain Eukaryota consists of organisms that have their nuclei enclosed by a membrane. This domain is divided into four kingdoms: Protista, Plantae, Fungi and Animalia. Binomial nomenclature is a classification system to name species, where the first word of the name indicates the genus of the species and the second part of the name indicates the species within the genus. Finally, reproductive isolation is a term used to indicate physiological, mechanical, behavioral and geographical barriers that prevent interbreeding between two different species.

Explain how a concentration gradient, a membrane protein, and hydrogen ions work together to provide a mitochondrion with the energy needed to join small molecules together. (6 points)
pls help asap :)
Answer:
you combine all the molicules
Explanation:
A concentration gradient, a membrane protein, and hydrogen ions work together to provide a mitochondria with the energy needed to join small molecules together through ATP. The H+ ions are pumped across by membrane “pump proteins” into a space bounded by memb ranes that contain numerous amounts of hydrogen ions. Then, electrons are passed from o ne membrane-bound enzyme to another, which causes some energy to get lost during eac h transfer. This “lost energy” allows the pumping of hydrogen ions against the concentratio n gradient. After all the steps are taken, the mitochondrion will be provided with the energy needed to join small molecules together.

As the rate of photosynthesis increases, what do you think happens to the rate at which sugars are produced by the plant?
Answer:
During photosynthesis, plants use the sun's energy to convert water and carbon dioxide into glucose (sugar), which is used for energy. As the rate of photosynthesis increases, so does the rate the plants make glucose.
As the rate of photosynthesis increases, the rate of sugar production in plants should also increase.
During photosynthesis, green plants utilize the radiant energy from the sun to produce carbohydrates with water and carbon dioxide serving as raw materials.
Carbohydrate in the form of sugar is produced directly from the process of photosynthesis according to the following equation:
[tex]6CO_2 + 6H_2O ---> C_6H_1_2O_6 + 6O_2[/tex]
Thus, if the rate of photosynthesis should increase, it automatically translates to the same increase rate in sugar production, other things being equal.
