The central atom in an amino acid that all the groups connect to is a
O A. Hydrogen
.
O B. Oxygen
• O C. Carbon
.
O D. Nitrogen
Answer:
C. Carbon
Explanation:
The central atom in an amino acid that all the groups connect to is a carbon atom.
Amino acids are monomeric units of proteins. They are bifunctional in that they have an amino group and a carboxyl group. These groups are attached to a carbon atom, α-carbon, in a molecule.
This is common to all amino-acids.

Answer:
codon ® gene ® DNA ® chromosome
Explanation:
The flow chart correctly organizes the structures of heredity, from least to the most complex - codon ® gene ® DNA ® chromosome
Chromosomesare thread-like structures located in the nucleus, which carries genetic information from generation to generation.an organized package of DNA, Different organisms have different numbers of chromosomes.DNADNA, or deoxyribonucleic acid, is the hereditary material in almost all organisms.Nearly every cell in a person's body has the same DNA.It has a huge number of nitrogen base sequences and specific segments called geneGeneA gene is the basic physical and functional unit of heredity.Genes are made up of DNA.genes vary in size from a few hundred DNA bases to more than 2 million bases that form codonsThus, The flow chart correctly organizes the structures of heredity, from least to the most complex - codon ® gene ® DNA ® chromosome

Why is it difficult for your body to return blood from your feet when you sit for too long?. Single choice. a. Blood has to travel a greater distance. B. Skeletal muscles are not squeezing the veins. c. Gravity makes the blood flow backward. d. The heart does not beat fast enough at rest.
Answer: Option C.
Gravity makes the blood flow backward
Explanation:
it difficult for your body to return blood from your feet when you sit for too long because gravity makes blood flow backward and this is because when you sit for long , it weakens the keg muscles because it is necessary for body movement so that blood will circulate or flow well. When the keg muscles becomes weak, it will slow blood flow in the leg and the force of gravity acting will make the blood flow backward and thus can cause a blood clot.

Most of the air pollution in the news is the result of
Answer:
burning of fossil fuels
Explanation:
Air pollution is human-provoked, because of the factories, powerplants, cars, planes, and most important, because of the burning of fossil fuels, such as coal, gas, oil, gasoline.
The indicator that shows how much fossil fuel is burned every day is carbon-dioxide, as it indicates how many dangerous gases are let in the air.

9. Transcribe this DNA sequence? AAT-CAG-CGT
Which statement best describes the end result of this process? a New molecules of mRNA are transcribed from the DNA molecule. b The new DNA molecules are made from opposite DNA strands so they are not identical. c A protein molecule is synthesized from the code in the DNA molecule. d Two new DNA molecules are formed, each identical to the original
Answer: c. A protein molecule is synthesized from the code in the DNA molecule.
Explanation: This shows the steps surrounding the central dogma of molecular biology stating that the genetic material, DNA contains the needed information and instructions for creating a protein, which are copied by RNAs. As such it follows that DNA is transcribed into RNAs which are in turn translated into proteins.

Marine ecosystems support a(high, low) diversity of life,
largely due to (constant unchanging conditions, a lack of natural predators, the variety of environments) throughout the ocean.
Answer:
high diversity, variety of environments
Explanation:
To this day, scientists are still discovering new marine animals. This is because of all of the different environments in the ocean, Some animals exist in tropical areas, others in freezing cold water. Some animals even exist solely in high pressure areas that are hundreds of meters below the surface. There are even organisms older than dinosaurs living in the ocean.

What is the function of mRNA in the diagram above?
The function of mRNA in the diagram given above is carrying the genetic message from DNA to the ribosomes.
What is the function of mRNA?
The main function of mRNA has to work as the immedieter between the protein and DNA which has been utilised by the ribosome for the process of the direct synthesis of protein, and the function of tRNA has to carry the accurate amino acid to the proteins synthesis site which takes place in ribosome.
RNA has backbone and it has to made up of phosphate group which has been arranged in alternating form and the sugar known as ribose other than the deoxyribose present in DNA. There are four bases found in RNA and these are adenine, uracil, guanine, and cytosine.
Liquid consist of small range of order and the reason behind this is intermolecular attractive force which is very strong and due to this reason molecules are packed together tightly.
Therefore, The function of mRNA in the diagram given above is carrying the genetic message from DNA to the ribosomes.

Which of the following is true about nucleic acids?
Both DNA, which stores genetic information and encodes protein sequences, and RNA, which is involved in the direct production of proteins, are nucleic acids.
Nucleic acids always consist of a five-carbon sugar, a nitrogenous base, and one or more phosphate groups.
Nucleic acids are usually insoluble in water and are used for long term energy storage.
Glucose, cellulose, and starch are examples of nucleic acids found in most cells.
Reset Submit
Answer:
Both DNA, which stores genetic information and encodes protein sequences, and RNA, which is involved in the direct production of proteins, are nucleic acids. Nucleic acids always consist of a five-carbon sugar, a nitrogenous base, and one or more phosphate groups.Explanation:
DNA and RNA are both made up of chains of nucleotides. They are responsible for holding, transmitting, and translating genetic information into proteins.
Nucleotides are made up of a 5 carbon sugar, (DNA is deoxyribose, RNA is ribose), a phosphate group, and a nitrogenous base. They are linked together by phosphodiester bonds. The sequence of nucleotides makes the DNA and RNA sequences unique and determines the structure and function of the encoded proteins
