(NEED HELP IMMEDIATELY) In a gene, which base sequence codes for two amino acids?
1. CTAA
2. AG
3. GAGCTC
4. GAA

Answers

Answer:

[tex]\boxed {\boxed {\sf 3. \ GAGCTC}}[/tex]

Explanation:

Amino acids are the monomers or building blocks of protein. Proteins are created during protein synthesis according to the genetic information or DNA in an organism.

The DNA is translated to messenger RNA in the nucleus. It travels to the ribosome. There, the mRNA is "read off" in threes. Three nucleotides make up  a codon. Transfer RNA with the corresponding anticodon and an amino acid attaches to the codon and a chain of amino acid forms.

If 3 nucleotides make 1 codon which makes 1 amino acid, then we need double that or 6 nucleotides to make 2 amino acids.

The only answer choice with 6 nucleotides is Choice 3: GAGCTC

Answer:

1. 3-methylpentane

2. 2-bromo-3-chloropentane

3. 2,2,4-trimethylpentane

Explanation:

1. CH3CH2CH(CH3)CH2CH3.

Methyl group is in the third carbon atom in the long chain. The organic compound has five(5) carbon atoms thus it is named as pentane.

Therefore the name of the compound is

3-methylpentane

2. CH3CH(Br)CH(Cl)CH2CH3

The compound has Chlorine and Bromine in the carbon chain. Chlorine is given as chloro-, Bromine is given as bromo, depending on the position in the carbon chain. Bromine is located in 2 carbon atom and chlorine is in third(3) carbon atom in the long chain. The long chain has five carbon atoms thus pentane.

Naming of the compound we begin with the on lowest in the alphabet. The name of the organic compound is therefore;

2-bromo-3-chloropentane

3. CH3CH(CH3)3CH(CH3)CH2CH3

In this long chained organic compound, methyl-group is found in 2,2 and 4th positions. Since this is still pentane, naming the organic compounds, we start with the one with the lowest carbon. Therefore this becomes;

2,2,4-trimethylpentane

I hope this helps you to know how to name the organic compounds.

Hi! hopefully this helps you

Explanation:

You can make a buffer solution for a specific pH (potential of hydrogen) by mixing together a weak acid like acetic acid HC2H3O2 with a salt that contains the conjugate base like sodium acetate NaC2H3O2. A neutralization reaction would occur as you are mixing a weak acid and a strong base.

When you add the base to an acidic solution, the solution becomes less acidic and moves toward the middle of the pH scale. Aka neutralization

Redox is a type of chemical reaction in which the oxidation states of atoms are changed. Redox reactions are characterized by the actual or formal transfer of electrons between chemical species, most often with one species undergoing oxidation while another species undergoes reduction. The chemical species from which the electron is removed is said to have been oxidized, while the chemical species to which the electron is added is said to have been reduced.
Transcription is the process of copying a segment of DNA into RNA. The segments of DNA transcribed into RNA molecules that can encode proteins are said to produce messenger RNA. Other segments of DNA are copied into RNA molecules called non-coding RNAS. Averaged over multiple cell types in a given tissue, the quantity of MRNA is more than 10 times the quantity of ncRNA.
Chelation is a type of bonding of ions and molecules to metal ions. It involves the formation or presence of two or more separate coordinate bonds between a polydentate ligand and a single central atom. These ligands are called chelants, chelators, chelating agents, or sequestering agents. They are usually organic compounds, but this is not a necessity, as in the case of zinc and its use as a maintenance therapy to prevent the absorption of copper in people
Catalysis is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst. Catalysts are not consumed in the reaction and remain unchanged after it. Often only very small amounts of catalyst are required. Catalysts generally react with one or more reactants to form intermediates that subsequently give the final reaction product, in the process regenerating the catalyst.

The boiling point of water is 100ºC. The boiling point of acetone is 56ºC. Which statement about distilling a mixture of acetone and water is correct?

Acetone remains in the original container.

Water will vaporize from the mixture before acetone.

Acetone is captured and cooled.

Water is collected as it leaves the mixture.

Answers

Answer:

Acetone is captured and cooled.

Explanation:

The boiling point of acetone is lower than that of water, so it will vaporise before water. Then acetone will be captured and cooled to separate it from its mixture with water.

The statement which is correct about distilling a mixture of acetone and water is as follows:

Acetone is captured and cooled.

Thus, the correct option is C.

What is Distillation?

Distillation may be defined as a procedure that generally involves the conversion of a liquid into a vapor that is eventually condensed back to liquid form. With the help of this process, the separation of components or substances from a liquid mixture by using selective boiling and condensation occurs.

Acetone has the lowest boiling point as compared to water. So, it boils faster than that water and vaporizes before water. After the termination of this process, the acetone will be predominantly captured and cooled to separate it from its mixture with water.

Therefore, the correct option for this question is C.

The diameter of neutral atoms generally decreases going left to right across one period on the periodic table. What change causes this decrease in diameter of atoms?

Answers

Explanation:

Atomic size gradually decreases from left to right across the periodic table because within a period of elements, all electrons are added to the same shell. However, at the same time, protons are being added to the nucleus, making it more positively charged. The effect of increasing proton number is greater than that of the increasing electron number. Therefore, there is a stronger nuclear attraction. This means that the nucleus attracts the electrons more strongly, pulling the atom's electron shells closer to the nucleus. As a result, the atomic diameter of the atom decreases.

URGENT PLEASE ELPP!!!Calculate the density of a piece of metal that has a mass of 2.5 × 102 kg and a volume of 4.1 × 103 m3.

Answers

Answer:

Density =mass/Volume

First of all let's find the mass

= 2.5 ×102kg

= 225kg

Then the volume

=4.1 × 103 m3

=422.3m3

225kg /422.3m3

=0.53279659

The density of a piece of metal that has a mass of 2.5 × 102 kg and a volume of 4.1 × 103 m3  will be 6.03  kg/m³ .

What do you mean by  the density of a substance ?

Density is defined as the ratio of mass of the object to the volume of the object. Different substances have different densities.

The mathematical expression for density is as follows:

Density=Mass/Volume

The mass of a substance is expressed in kilograms and the volume is expressed in liter.

Thus, the unit of density is kg L⁻¹.

The density of a substance does not depend on the amount of the matter.

Thus, density is an intensive property.

To calculate  the density -:

Given,

Mass= 2.5 ×102 kg=2550 kg

Volume=4.1 × 103 m³=422.3m³

Density=mass/volume

Density=2550/422.3

Density=6.03kg/m³

Hence, 6.03kg/m³ is the  density of a piece of metal .
