Answer: protons
Explanation:
Changing the number of protons would change it into an atom of a different element.
Hello! Your answer is protons.
There are three main parts of any atom. The proton, neutron, and electron. The proton and neutron form the center of the atom, or the nucleus, while the electrons float around them.
The protons determine the element. The number of protons is the atom's atomic number. For example, if there were 6 protons, the element would be the one with an atomic number of 6, or carbon. If there was just one, it would be hydrogen as that has an atomic number of 1.
When you change the number of neutrons, you get isotopes. This changes the atomic mass, as neutrons' main impact is mass. This also can mainly change stability. When you change the number of electrons, you change the charge of an atom. Electrons' main purpose is to bond + charge the atom. Electrons don't weigh much, they barely weigh anything. They instead give a negative charge to an atom (while the proton gives a positive)

Which of the four levels of protein structure is maintained after denaturing? Explain your answer.
Answer:
Primary structure and quaternary structure because the heat energy will disrupt only the weaker interactions which causes the secondary and tertiary structure to break down.
Explanation: sorry no explanation :(
Among the four levels of protein structure, only the primary structure remains after denaturing.
The primary structure, which is the sequence of amino acids in the protein, survives because it's held together by sturdy covalent bonds.
Proteins have four hierarchical levels of structure: Primary, Secondary, Tertiary, and Quaternary.
However, only the primary structure of a protein can be maintained after a denaturing process.
Denaturing events, such as changes in temperature or pH, disrupt the interactions that hold the secondary, tertiary, and quaternary structures together.
Conversely, the primary structure, which refers to the sequence of amino acids in a protein, is held together by covalent bonds that remain intact during denaturation.

Transcribe the mRNA sequence (A T G C G C A T T A G T G C A G G A C A G T A G) into a protein using the codon chat below. Write your answer in the following format: _____ - _____ - _____
Answer:
DNA ATG CGC ATT AGT GCA GGA CAG TAG
mRNA UAC GCG UAA UCA CGU CCU GUC AUC
tRNA AUG CGC AUU AGU GCA GGA CAG UAG
Protein Met Arg Ile Ser Ala Gly Gin Stop
Explanation:
The given is a DNA sequence. The next step to this one is transcribing it into a mRNA sequence. When you transcribe DNA to RNA, the main difference between RNA and DNA is that RNA does not have a THYMINE (T) base. So what do we do?
The base pairs would be:
G - C T - A
C -G A - U
U - A
So keep this in mind. Let's take the first one codon (codon is a group of 3 bases):
A T G
U A C
A transcribes to U
T transcribes to A
G transcibes to C
So that would be your first codon.
The next part wi=ould be translation. Now in translation, a specific amino acid codes for a specific codon. They are brought by tRNA, which has a anti-codon that codes for the amino acid it carries.
Let's take that same codon we transcribed earlier:
ATG
UAC
AUG
Looking at the chart, first look at the first letter, then match it up with the row it corresponds to.
So it falls under A, so look at the row of A.
The next step is to look at the column the second letter corresponds to, following the same row you started in.
Last would be the row within the column you identified that corresponds to the third letter of the codon.
As you can see you wil end up in the box:
AUU
AUC
AUA
AUG
The higlighted sequence is the codon we are examining and based on the box, you can see that it is the Met. So this would be your first amino acid, and this is also known as the start codon by the way.
Q3: Describe why Jupiter, Saturn, and Uranus have the most moons.
Answer:
Explanation:
São os mais afastados do Sol. Júpiter: É o maior planeta do Sistema Solar e recebeu o nome do rei dos deuses. Júpiter é uma imensa esfera gasosa, com uma massa duas vezes maior do que a de todos os outros planetas juntos. É o que mais possui satélites naturais (luas).
Answer:
So why does other planets like Jupiter Saturn and uranus have the most moons? Simply because they are so big and can collect more moons verses other planets like earth that has only one moon.
For example, if comets swing by them, they can sometimes absorb comets, allowing them to grab asteroids as well. Including the much material that starts to condense into that big planet. There is more left behind that swirled around the planet leaving behind more moons.
So the reason is, is because of their great size that makes those planets with the most moons.
Hope this helped you!

Darwin’s theory of evolution is based on
Charles Darwin's theory of evolution operates on three key principles: the struggle for existence, variation and adaptation, and survival of the fittest or natural selection. This explains how species evolve over time based on adaptive traits that support survival and reproduction.
Explanation:Charles Darwin’s theory of evolution is a fundamental concept in biology and is based on several key principles. These are: the struggle for existence, variation and adaptation, and survival of the fittest or natural selection. The struggle for existence proposes that species produce more offspring than the environment can support, leading to a struggle for resources. His notion of variation and adaptation suggests that individuals within a species show variations in their characteristics, and those with adaptive traits are more likely to survive and reproduce. Lastly, the principle of survival of the fittest, or natural selection, explains that those individuals with the most suitable traits will survive and pass on these traits to their offspring, leading to the evolution of species over time.

A quantity must be divided by multiples of ten when converting from a larger unit to a smaller unit.
Please select the best answer from the choices provided
T
Or
F
Answer:False
Explanation:You're supposed to have numerically more smaller units than bigger units, since a lot of these smaller units are combined to create a single larger unit.
The given statement is False because a larger quantity is not divided by multiples of ten when it needs to be converted to a smaller quantity.
We multiply a larger quantity with the multiples of ten to convert it to a smaller unit during unit conversion.
For example, if you need to convert 3-kilo meters into meters -
You know that 1 km = 1000 meters,
So, to convert, let's consider x meters = 3 kilometers.
[tex]\frac{1}{1000} = \frac{3}{x}[/tex]
[tex]x = \frac{3 * 1000}{1}[/tex]
[tex]x = 3000[/tex] meters
Another example – you need to convert 2 milligrams (mg) into micrograms,
We know that 1 mg = 1000 micrograms
[tex]\frac{1}{1000} = \frac{2}{x}[/tex]
[tex]x = \frac{2*1000}{1}[/tex]
[tex]x = 2000[/tex] micrograms
This proves that, whenever you need to convert a higher unit into a lower unit, you need to multiply it by multiples of 10. Therefore, the given statement is False.

which atom is a carbon atom?
A.
B.
C.
Answer: B
I'm going to as B
Explanation: :)
The carbon atom from the diagram given is located in Option B.
The Carbon atom (C) is known to be a chemical element that can be seen on the periodic table with the atomic number 6. Its electronic configuration is configured as 1s² 2p² 2s².
In the energy levels, the first subshell is known as the principal quantum number, and the total number of electrons that can be present in the first subshell is determined by using the formula 2n².
So, in the first subshell, the total number of electrons is:
= 2(1)²
= 2 electrons.
The second subshell, the tota number of electrons is:
= 2(2)²
= 2(4)
= 8 electrons
Since we know that Carbon contains 6 electrons and in the first shell, two of the electrons are filled and occupied, so we will be left with 4 valence electrons in the second subshell. This gives the characteristics properties of the tetravalent nature of carbon compound.
Therefore, we can conclude from the above concept that the correct structure representing the carbon atom can be seen in Option B.

A
Explanation:
the Giant impact hypothesis formed when an object smashed into early Earth.
Answer:
Fission Hypothesis
Explanation:
This theory proposes that the Moon was once part of the Earth and somehow separated from the Earth early in the history of the solar system. The present Pacific Ocean basin is the most popular site for the part of the Earth from which the Moon came.
This theory was thought possible since the Moon's composition resembles that of the Earth's mantle and a rapidly spinning Earth could have cast off the Moon from its outer layers.
However, the present-day Earth-Moon system should contain "fossil evidence" of this rapid spin and it does not. Also, this hypothesis does not have a natural explanation for the extra baking the lunar material has received

1. What is the Small structure in a cell that performs a specific function
In cats having hair dominant (H) over not having hair (h). If a male cat that is hetrozygous for hair is crossed with hairless cat.
What are the parents genotypes?
Answer/Explanation :
A heterozygous cat has a genotype Hh
A hairless cat has a genotype hh
When crossed, the results could be any of the following:
Hh (with hair)
hh (hairless)
There is a 50:50 chance or 1: 1 ratio that the offspring will have hair.
Final answer:
In a genetic cross involving cats where hair is dominant over hairlessness, a heterozygous male cat (Hh) mated with a hairless female cat (hh) results in offspring that are predicted to have a 1:1 ratio of haired (Hh) to hairless (hh) genotypes.
Explanation:
The question regards a genetic cross concerning hairlessness in cats, a trait determined by a single gene with two alleles: hair (H) is dominant over no hair (h). When a heterozygous male cat (Hh) is mated with a hairless (hh) female cat, we are examining a simple Mendelian cross to determine the offspring's potential genotypes.
The parents' genotypes in this scenario are as follows:
Male cat: Heterozygous for hair (Hh).Female cat: Homozygous recessive for no hair (hh).This cross results in a Predicted offspring phenotype ratio of 1:1, where 50% of the offspring are expected to be heterozygous with hair (Hh) and 50% are expected to be hairless (hh).

Substance A has a melting point of 100°C.
Liquid Substance B has a freezing point of
110°C. For each substance, identify its state
of matter, and describe the motion of its
particles, when the substance is at 115°C.
melting point and the freezing point are the same things.
so both the substance will be in liquid state.
the particles will be able to move somewhat but not as much as the particles in gas phase.
substance A particles will show same amount of motion as the particles of substance B because the temperature of A and B is same and they will posses same Kinetic energy as the formula for Kinetic energy is :-
KE = 3/2 × (boltzman constant) × temperature of substance
but their potential energies will differ substance A will have more potential energy than substance B because the temperature of A is more than the temperature of B.
PLEASE TELL IF IT IS RIGHT OR WRONG.
Answer:
Both substance A and B will be at liquid state at 115 degree Celsius.
Explanation:
Substance A
Melting point of substance A is 100 degree Celsius. Thus, temperature higher than 100 degree will result into liquid substance A. Thus at 115 degree Celsius, substance A is liquid and the particle will be free enough to move and slide over each other.
Substance B
The freezing point of substance B is 110 degree Celsius. This means that for any temperature higher than 110 degree Celsius, substance B will occur in liquid state. The particles of solution B at liquid state will also be free enough to move and slide over each other.
DNA is a nucleic acid that consists of thousands of smaller, repeating units called nucleotides.
What function do nucleic acids serve besides storing genetic information?
Answer:
Besides storing genetic information, nucleic acids helps in
Understanding diseases
Creation of proteins
Transmission of information
Explanation:
Understanding diseases
Knowledge about the nucleic acids and their mechanism of action helps in understanding the causes of a disease and the possible cure for the disease. A genetic disease is caused when there is a faulty gene, which is made up of nucleic acids, is present in the genome. These genes will make faulty RNA's which will result in the establishment of faulty proteins. Hence, by having understanding about nucleic acids, diseases can be studies and cured.
Creation of proteins
The information from the DNA is coded by the mRNA which is used to make proteins.
Transmission of information
Apart from storing information, the nucleic acids such as the DNA are also involved in the transmission of information.
Nucleic acids, besides storing genetic information, are instrumental in the synthesis of proteins. They work to construct proteins based on the instructions carried by the DNA. Additionally, they play a part in regulating cell processes and help in energy production.
Explanation:Nucleic acids, in addition to their principal role in storing genetic information, play several other vital functions in our bodies. Primarily, they are instrumental in the synthesis of proteins, which are the building blocks of cells. DNA, or deoxyribonucleic acid, carries the instructions for the production of these proteins, while another nucleic acid known as RNA (ribonucleic acid) works to construct the proteins based on these instructions.
Further, RNA also functions in other capacities, such as acting as a messenger (mRNA) that conveys the genetic code from the DNA to the ribosomes, sites of protein synthesis. Additionally, transfer RNA (tRNA) and ribosomal RNA (rRNA) both play critical roles in protein synthesis. Nucleic acids also play a part in regulating cell processes and help in the formation of ATP (adenosine triphosphate), the main energy source for many cellular processes.

what happens to most of the light energy during photosynthesis?
Answer:
uses the energy of sunlight to convert water and carbon dioxide (reactants) into high-energy sugars and oxygen (products).
Explanation:Summarize what happens during the light-dependent reactions of photosynthesis. ... NADP+ molecules pick up the high-energy electrons along with H+ ions to become NADPH.
Most of the light energy absorbed during photosynthesis is used to generate ATP and NADPH in the light-dependent reactions, which are later used in the Calvin cycle to produce carbohydrates, effectively storing solar energy as chemical energy.
Explanation:During photosynthesis, most of the light energy is converted into chemical energy. This transformation begins when sunlight is absorbed by chlorophyll, a pigment in the thylakoid membranes of the chloroplasts. A photon strikes photosystem II initiating the process where energy is transferred through an electron transport chain and is used to pump hydrogen ions into the thylakoid space, establishing an electrochemical gradient.
The hydrogen ions flow through ATP synthase, a process known as chemiosmosis, to form ATP, an energy carrier molecule. Photosystem I absorbs a second photon, leading to the formation of NADPH. Both ATP and NADPH are then utilized in the Calvin cycle to create sugar molecules. Ultimately, the light energy absorbed by plants is stored as chemical energy in carbohydrates, serving as fuel for life on Earth.

The instructions for making proteins are coded in the DNA of a cell. In a eukaryotic cell, these instructions are located in the nucleus. When a protein is to be produced, the information from the DNA is transcribed into messenger RNA (mRNA). This mRNA then travels from the nucleus to a ribosome in the cytoplasm or on the rough endoplasmic reticulum (RER), where it serves as a template to assemble amino acids into a protein through a process called translation.
Depending on where the protein is needed, it is synthesized either by free-floating ribosomes in the cytoplasm or by ribosomes bound to the RER. If a protein is to be secreted outside the cell, incorporated into the cell's plasma membrane, or targeted to a lysosome, it is typically synthesized by ribosomes on the RER.

3. The hours of daylight can vary greatly because of latitude. How would being near the equator shape the amount of sunlight per day in those countries? Explain your answer.
4. Would a La Niña event have a negative impact on wildlife? Explain your answer.
5. Why do you think some people have a difficult time believing that global warming is real?
Answer:
NUMBER ONE: a) a metal pan b)cover/blanket
Explanation:
a) it retains heat because when its heated, it heats fast, if cooled it cools fast
b) a blanket/cover actually contains heat thats how it gets you warm it traps the heat that enters it and keeps it heated.
A ceramic tile holds heat like water. If water didn't retain heat, the Earth's climate would be more extreme. Being close to the equator leads to more consistent sunlight hours, a La Niña can negatively impact wildlife and people may struggle with believing in global warming due to misinformation or political beliefs.
Explanation:1. A common household item that shares the characteristic of retaining heat like water would be a stone or ceramic tile. These materials can retain heat for extended periods of time due to their high thermal mass similar to water. If you place them in the sun or heat them, they stay warm for a while even after removing the heat source.
2. If water did not hold heat, the climate of the earth would be very different. Because water retains heat, it helps to moderate the Earth's climate making it habitable. Without this property, we would experience temperature extremes as land does not hold heat as well as water.
3. Being near the equator would generally mean more consistent hours of daylight throughout the year compared to areas further away from the equator. This is because the Earth's tilt does not change the amount of sunlight received at the equator as drastically as it does in other areas.
4. A La Niña event, which is characterized by cooler sea surface temperatures in the Pacific, could certainly have an impact on wildlife. Changes in water temperatures can alter the habitats and food supplies of marine life. However, it's not always negative, as some species might benefit from these changes.
