5. How could one change in a DNA nucleotide alter the formation of the translated protein? (In other words, what could happen to the finished protein if you change just one base letter in the entire code of DNA, and instead of it being ACTGCCAGCCTa it was changed to ACTGCCAGCCTg?
DNA codes for proteins by the sequence of nucleotides in the DNA. Each set of 3 nucleotides codes for a specific amino acid. Sometimes, a change in a nucleotide does NOT change the amino acid (and therefore, the protein) because some amino acids have more than one set of 3 nucleotides that code for them

The deflection of fluids due to the rotation of earth is the Coriolis effect.
True
False
Answer:
True.
Explanation:
Earth rotation can be defined as the amount of time taken by planet earth to complete its spinning movement on its axis. This ultimately implies that, the rotation of earth refers to the time taken by earth to rotate once on its axis. One spinning movement of the earth on its axis takes approximately 24 hours to complete with respect to the sun.
Basically, the effect of the Earth spinning on its axis on winds and currents is that, global winds will move along a curved path and therefore cause ocean currents to curve.
As a result of the Earth's rotation on its axis, a phenomenon known as Coriolis effect arises.
Coriolis effect occurs when circulating winds are deflected to the left in the southern hemisphere and to the right in the northern hemisphere.
Hence, rather than have this air circulating in a straight pattern, it is deflected to the left of the southern hemisphere and to the right of the northern hemisphere, typically in a curved path or pattern.
In conclusion, we can say that the deflection of fluids due to the rotation of earth is the Coriolis effect.

eukaryotic cells, what are three structures the cells shown
below would have in common?
Answer:
For number 3:
The bacterial cell is a prokaryotic cell and the fungal cell is a eukaryotic cell.
Explanation:
I cannot see the cells to answer number 4, but for number three, bacteria is a prokaryote and fungal cells are eukaryotes. You can most likely determine this by the presence of a nucleus (a prokaryote cell will not have one where a eukaryotic cell will).
2) The signal to contract is distributed deep into the muscle fiber by the
a) Sarcolemma
b) Sarcomere
c) Transverse tubules
d) Myotubules
e) Myofibrils
Answer:
c) Transverse tubules
Explanation:
The transverse tubules (T tubulars) are called these channels because they cross the filament. A network of interconnecting rings, each of which encircles a myofibril, is the transverse tubular structure. It provides an essential pathway of contact between the fiber outside and the myofibrils.

How are the graphs of a body chemical controlled by negative feedback and a body chemical controlled by positive feedback similar? How are they different?
Answer:
brainliest plzzzzz
Explanation:
There is a proper mechanism of controlling the levels of various kinds of hormones and chemicals in our body called as positive feedback and negative feedback.
In a very simple language you can understand it as whenever there is a release of a particular hormone or chemical inside the body in very huge amount then the negative feedback of the body is activated the production of that particular hormone or chemical is stopped and vice -versa for negative feedback.
Explanation:positive feedback and negative both the feedback mechanism are achieved to maintain the proper homeostasis.
Example: release of clotting factor after blood loss is a positive feedback and a hormone is released and then suddenly there is a increase in hormone b, then the amount of hormone a will decrease this is a negative feedback.

Explanation:
Look at metaphase and anaphase. Suggest the purpose of the spindle fibers during mitosis.
Answer:
The spindle fibre is necessary to separate the sister chromatids into opposite sides of the cell.
Please find detailed explanation below
Explanation:
Mitosis is the cell division that produces two daughter cells that are genetically identical to the parent cell. Mitosis occurs in stages viz: prophase, metaphase, anaphase and telophase. The replicated chromosome, aligns at the centre of the cell in the METAPHASE stage and separates into opposite poles in the ANAPHASE stage.
This alignment (at the equator) and separation into opposite pole is possible with the aid of a structure called SPINDLE FIBRES. Spindle is a structure formed from microtubules, which attach to the kinetochores (located in the centromere) of each replicated chromosome to separate them from one another. Hence, the purpose of the spindle fibre during mitotic division is to separate the GENETIC MATERIAL of a parent cell into two daughter cells.
a researcher proposes a model of an enzyme catalyzed reaction in which reactant is converted to a product. The model is based on the idea that the reactant passes through a transition state within the enzyme substrate complex before the reactant is converted to the product. which of the following statements best helps explain how the enzyme speeds up the reaction ?
Answer:
The enzyme's active site binds to and stabilizes the transition state, which decreases the activation energy of the reaction.
Explanation:
Enzymes are complex multi-folded forms of proteins - they promote chemical reactions in biological processes.
Typically, molecules collide at random, and complex chemical reactions require the right molecular orientation and energy to react (breaking and forming bonds).
Enzymes lower energy needs by providing an alternative reaction pathway and stabilize and maintain the molecules in their intermediate forms called transition states.

The one that is not the responsibility of police is to maintain peace during extraordinary circumstances. The correct option is B.
What is law and order?Law and order is a situation in which a country's laws are obeyed, particularly when the police or army are used to ensure this: a complete breakdown in law and order.
When proper laws are in place that allow all humans to exist as equals, it becomes very easy for everyone to pursue the opportunities that they desire. This is significant because it means that everyone has the freedom to pursue their dreams in life.
To summarize, the relationship of law and order to the rule of law has the following characteristics.
The rule of law is based on general rules to keep order, whereas law and order is based on specific commands and directives in response to exigencies.
The one that is not the responsibility of the police is to keep the peace in unusual circumstances.
Thus, the correct option is B.

Your question seems incomplete, the probable complete question is:
True, it is the function of the army to maintain law and order in abnormal times. But in normal times there is another force that compels citizens to obey laws and to act with due regard to the rights of others. The force also protects the lives and properties of law abiding men. Laws are made to secure the personal safety of its subjects and to prevent cut murder and crimes of violence. They are made to secure the properly of the citizens against theft and damage and to protect the rights of communities and castes to carry out Their customs and ceremonies, so long as they do not conflict with the rights of others. Now the good citizen, of his own free will obeys these laws and he takes care that everything he does is done with due regard to the rights and well being of others.
But the bad citizen is only restrained from breaking these laws by fear of the consequence of his action. And the necessary steps to compel the bad citizen to act as a good citizen are taken by this force. The supreme control of law and order in a state is in the hands of a Minister, who is responsible to the state Assembly and acts through the state Assembly and the Inspector General of Police.
According to the writer, which one of the following is not the responsibility of the police?
To protect the privileges of all citizens.To maintain peace during extraordinary circumstances.To ensure peace among citizens by safeguarding individual rights.To check violent activities of citizens.Nucleic acids are synthesized from monomers that are activated by linking them to a carrier molecule in an energy-requiring reaction.

A position effect variegation (PEV) phenotype can be used to identify new genes that regulate heterochromatin formation. For example, strains of Drosophila melanogaster with the white variegation phenotype can be subjected to mutagenesis to screen for mutations in other genes that suppress PEV, meaning the mutation results in a lower white pigment production. Using what you know about the enzymes that control heterochromatin spreading, describe one mutation that you would expect to be a suppressor of variegation
Answer:
by mutation of genes encoding histone modification enzymes that lead to loss of gene repression by the alteration of the chromatin structure
Explanation:
Histone methylation is an important epigenetic modification involved in regulation of gene expression. Histone methyltransferases and histone demethylases are enzymes capable of modifying the chromatin structure by adding or removing methyl groups of the N-terminal of the core histones, respectively. There are suppressor of variegation (Su-var) enzymes capable of removing activating chromatin marks such as, for example, histone H3 lysine methylation, thereby mutations in these epigenetic modifiers may result in a loss of gene silencing by directly opening the chromatin structure. For example, Su(var)3–9 is a histone lysine methyltransferase enzyme that controls the formation of heterochromatin.
Examination of the amino acid composition of a newly isolated protein indicates the presence of 10 lysines, 5 arginines, and 4 methionines. When the protein is treated with cyanogen bromide, four peptides are obtained. When it is treated with trypsin, 16 peptides are obtained. What do these results suggest regarding the sequence of the protein
Answer:
The protein has a lysine or arginine at it's C-terminal end.
Explanation:
Given isolated protein indicates the presence of 10 lysines, 5 arginines, and 4 methionines. So, sequence of the protein . These results indicate that the sequence of proteins contains lysine or arginine at the end of the C-terminal. Because we have 15 sites that can be separated from trypsin and so it only causes 16 peptides.A food shows many food chains within a community and how they overlap.
Answer:
The food chain describes who eats whom in the wild. Every living thing—from one-celled algaeto giant blue whales—needs food to survive. Each food chain is a possible pathway that energy and nutrients can follow through the ecosystem.
For example, grass produces its own food from sunlight. A rabbit eats the grass. A fox eats the rabbit. When the fox dies, bacteria break down its body, returning it to the soil where it provides nutrients for plants like grass.
Of course, many different animals eat grass, and rabbits can eat other plants besides grass. Foxes, in turn, can eat many types of animals and plants. Each of these living things can be a part of multiple food chains. All of the interconnected and overlapping food chains in an ecosystem make up a food web.
Answer:
A food web?
Explanation:
Food webs are multiple food chains overlapped. (Usually in the same area)
