what is the answer of this question?

Answer:

It's C

Explanation:

They are geometric isomers. Thus option C is the correct answer.

Two chemical species with the same number and types of atoms but different configuration are called as isomers, the spontaneous process by which isomers are formed called isomerization.

This process is independent of bond energy of the configurations.

Different types of isomers are structural isomers, geometric isomers, stereoisomers, optical isomers.

The major type called structural Isomers where atoms and functional groups are differently joined with each other. For example, 1-fluoropropane and 2-fluoropropane positional change.

Another types is stereoisomers formed between atoms and functional groups with differential geometrical positioning.

This class include enantiomers which are non-superimposable mirror images of each other and have chiral centers. example are D-threose and D-erythrose.

In stereoisomers, the class of diastereomers have different physical properties and reactivities.

Thus option C is the correct answer.

It is extremely important to know all types of blood because if you donate the wrong type of blood to another person, he/she will get sick.

Explanation:

Hemolytic transfusion reactions can cause the most serious problems, but these are rare. These reactions can occur when your ABO or Rh blood type and that of the transfused blood do not match. If this happens, your immune system attacks the transfused red blood cells. This can be extremely life-threatening.

Answer:

The correct answer is B. A phosphate group and 2 fatty acid chains.

Explanation:

A P3 X

Each phospholipid is made up of a phosphate group and two fatty acid chains. The correct option is B.

Phospholipids are lipids that have two types of edges. It has a hydrophobic tail and a hydrophilic head.  The plasma or cell membrane, according to the fluid mosaic model, comprises substances like proteins and phospholipids.

A phosphate head and a fatty acid (lipid) tail make up the phospholipid layer, also known as the phospholipid layer, which is formed by the phospholipid.

Small molecules like oxygen gas can diffuse through the phospholipid layer, which facilitates the passage of small molecules but not larger ones. Biological membranes are formed by two lipid layers, proteins, and glucans.

Therefore, the correct option is B. A phosphate group and two fatty acid chains.

Answer:Esta cobertura comprende las tierras bajas, que generalmente permanecen inundadas durante la mayor parte del año, pueden estar constituidas por zonas de divagación de cursos de agua, llanuras de inundación, antiguas vegas de divagación y depresiones naturales donde la capa freática aflora de manera permanente o estacional. Comprenden hondonadas donde se recogen y naturalmente se detienen las aguas, con fondos más o menos cenagosos. Dentro de los pantanos se pueden encontrar cuerpos de agua, algunos con cobertura parcial de vegetación acuática, con tamaño menor a 25 ha, y que en total representan menos del 30% del área total del pantano.

Distribución geográfica: Las zonas pantanosas se identificaron en las llanuras de inundación a lo largo de los ríos Caquetá, Caguán y Orteguaza y sus tributarios en el departamento del Caquetá; a lo largo del Río Guaviare en el norte de la región amazónica y en el río Vaupés en los departamentos de Guaviare y Vaupés.

Answer:

1. Fats contain mostly C-H bonds, it has less oxygen therefore making it a high energy compound

2. mRNA plays a vital role in protein synthesis. It's a single stranded RNA molecule that contains genetic information that can be taken outside the nucleus (unlike DNA which cannot leave the nucleus). Its created during transcrption, and is used during translation to create proteins

3. (Look at image)

1. The organic molecules that contain esters of fatty acids and a mixture of compounds are called fats. They provide energy to the body for functioning. They provide slow energy but the most efficient energy.

The amount of calories supplied by fats is twice as compared to carbohydrates and proteins. The excess of fats is stored in the body for future purposes.

2. mRNA is a type of RNA and plays a vital role in the process of translation. It is a single-stranded molecule that contains genetic information transcripted from DNA and is transported out from the nucleus into the cytoplasm.

The main function of mRNA is in protein synthesis. It helps in the formation of amino acid sequence that undergoes modification to form proteins.

3. The general formula of amino acid is [tex]\rm R-CH(NH_{2})-COOH[/tex].

The side chains of different amino acids vary accordingly. The structure consists of a carboxylic group along with an amino group and an organic side chain.

Answer:

True

Explanation:

Diffusion is a passive process (no energy required) in which the substance such as liquid and gases moves from an area of high concentration to an area of low concentration.

During respiration, carbon dioxide diffuses from the blood into the alveoli and oxygen diffuses from alveoli to blood across the respiratory membrane. The partial pressure of oxygen is low in the blood of the pulmonary capillaries and high in the alveoli. so diffusion allow movement of oxygen across the respiratory membrane from the alveoli into the blood.

Hence, the given statement is true.

Answer:

Explanation:

Substitution:

Substitution is the switch of codons. A C could be switched to an A, but the original is now substituted for the new codon. This can change the amino acid present or it can be a silent mutation. If the stop codon is switched in, the protein will be cut short and the effects could be very serious.

Insertion:

Insertion is where base pairs are inserted into the DNA. This is different from substitution because nothing is getting switched out, just new ones are getting inserted. The original codons will still be present, just new ones are coming in. Insertions result in a frame-shift, which means everything after the mutation is shifted and nothing will be correct after this. Insertions are more harmful than substitution because it doesn't affect just one amino acid, but many.

Deletion:

Deletion is where some codons or DNA is deleted. This will result in everything after the mutation being incorrect and can cause drastic effects. Deletion is very similar to insertion because they both cause a frame-shift, but also very different because they do the opposite from one another. Deletion is also more harmful than substitution because of the frame-shift and the change in future amino acids.

Answer:

Explanation:

In eukaryotic cells, the cytoskeleton is composed of three well defined filamentous structures: microtubules, microfilaments, and intermediate filaments. Each of these filamentous structures is a polymer of proteinic subunits united by weak, not covalent connections.

The microfilaments are the thinnest of the three structures. They have a diameter of 7 nanometers and are composed of many proteinic monomers united. This monomeric protein is called actin. Many monomers get combined to form a structure that assembles a double helix.

Due to the fact that these microfilaments are made of actin monomers, they are also known as actin filaments.

Actin filaments have directionality which means that their extremes have different structures.  

Microfilaments interact with myosin filaments. These are associated with transmembrane proteins that have one domain in the cytosol and another in the cell exterior, therefore they participate in the processes of cell mobility.

Answer:

Different transfer RNAs (tRNAs) selectively bind to N-terminal and internal AUG codons of bacterial polypeptides .

Explanation:

In prokaryotic organisms, N-formylmethionine (fMet) is coded by the start codon (AUG), thereby generating the most N-terminal residue of bacterial proteins. This residue (fMet) is a modified methionine amino acid that contains attached a formyl group to its amino group. Remarkably, it has been shown that formylmethionyl-tRNA only can bind to this initial AUG codon, while methionyl-tRNA binds to internal AUG codons.
