Atoms are made up of three types of particles: protons, neutrons, and electrons. Protons are positive, neutrons are neutral, and electrons are negative.

Atoms, the basic units of matter, are composed of three primary types of subatomic particles. The first type are

protons

, which carry a positive electric charge. The second type are

neutrons

, which have no charge. Both protons and neutrons reside in a region within the center of the atom known as the nucleus. The third type are the

electrons

, which carry a negative charge and move around the nucleus. The equal number of protons and electrons in an atom keep the atom neutrally charged.

Answer:

electrons in two orbitals.

Explanation:

In a double covalent bond, a carbon atom shares four electrons, two in each bond or in two orbitals.

In a double covalent bond, a carbon atom shares four electrons, with two electrons being shared in each bond. This is related to the electron configuration of carbon, which has six electrons: two in the inner shell, and four in its valence (outer) shell. It needs four more electrons to achieve a full outer shell. Therefore, it's most accurate to say that the carbon atom in a double covalent bond shares electrons in two orbitals, or simply four electrons (option c and d).

Answer:

The answer is D for E2020

Explanation:

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.

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.

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.

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.

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.

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.

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.

The instructions for producing proteins are encoded in the DNA of a cell, and in a eukaryotic cell, the DNA is located in the nucleus. During protein synthesis, mRNA copies the DNA's information and carries it to ribosomes, which are in the cytoplasm or on the RER, to create proteins.

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.

DNA protein binding occurs in the nucleus of a cell and involves transcription factors that bind to specific DNA sequences to regulate gene transcription. The translation of these genetic codes leads to protein synthesis, dictating the varied cell functions.

DNA protein binding typically occurs in the nucleus of a cell. It happens because proteins often play a role in gene regulation. These proteins, often referred to as transcription factors, bind to specific sequences in the DNA to regulate the transcription of genetic material to RNA, which eventually leads to protein synthesis.

For example, when a cell needs to produce a specific protein, a corresponding transcription factor binds to the DNA sequence, initiating the process of transcription. This process ultimately guides the assembly of a protein encoded by the DNA sequence.

Therefore, DNA protein binding is an essential step in translating the genetic instructions present in our DNA into the functioning proteins that carry out numerous roles within the cells.

The lack of rigidity in a body indicates death occurred less than a few hours ago or more than 48 hours ago, as these timeframes straddle the temporary condition of rigor mortis. Significant joint disarticulation suggests a more extended period post-death, during decomposition.

The assessment of the time since death based on the rigidity of a body involves an understanding of rigor mortis, which is a biological and medical concept. If a victim's body is not rigid, it suggests that the person has been dead for either a short period, generally less than a few hours during which rigor mortis has not set in, or a longer period typically more than 48 hours after death in which rigor mortis has passed and the body has returned to a more relaxed state. Significant joint disarticulation, as mentioned in some of the provided excerpts, occurs at an even later stage when the body has started to decompose and the connective tissues have broken down.

Final answer:

If the victim's body is not rigid, it could imply that the individual has been dead for either a very short period (less than 2 to 6 hours) or for an extended period (over 72 hours), as these time frames are relevant to the process of rigor mortis. Several factors, including environmental conditions and the individual's pre-mortem state, influence this timeline.

Explanation:

If a victim's body is not rigid, it suggests that rigor mortis has either not yet set in or has passed. Rigor mortis is a temporary state where the muscles of the deceased's body stiffen post-mortem. It typically begins within 2 to 6 hours after death and can last up to 72 hours. Once it subsides, the body returns to a state of laxity. Therefore, if a body is not rigid, the person could either have been deceased for a very short time, not exceeding a couple of hours or the body has been dead for more than 72 hours and rigor mortis has ended, leading to the loosening of the muscles.

Additional factors like ambient temperature, the physical condition of the victim prior to death, and other environmental conditions can also affect the rate at which rigor mortis sets in and dissipates. Likewise, the presence or absence of joint disarticulation, as noted in archaeological findings, may suggest a longer period between death and burial, allowing decomposition to begin. Signs like significant joint disarticulation indicate that these bodies had begun to decompose prior to burial, thus loosening the connective tissues and joints. However, determining an exact time of death is a complex process that often requires more information and context than simply the presence or lack of body rigidity.

Furthermore, anecdotal reports and historical records of post-mortem examinations can offer insights into the timing of death and burial practices. For instance, in the case described, the quick burial and subsequent exhumation of a beaten girl for examination by a coroner shows the historical urgency of burying the dead quickly and the implications this might have on the understanding of post-mortem changes.

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.

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.

5. Some people may have a difficult time believing in global warming due to misinformation, political beliefs, or simply a lack of understanding about the scientific evidence supporting it.
