experiment yeast fermentation ,what is the purpose of boiling the glucose solution earlier?​

Answers

Answer 1

Answer:

The correct answer is - to sterilize it and remove any oxygen.

Explanation:

Boil the glucose solution to sterilize it and remove any oxygen, leaving behind the glucose needed for anaerobic respiration. High temperature kills all the microbes and sterilizes the solution.

Boiling the glucose solution earlier also helps in removing the oxygen from the solution for preparing the anaerobic respiration in the experiment desired. Sterilization of the solution also helps it in avoiding any microbes to present in the solution and affect the experiment.

b. glucose

Answers

The answer is C hope it is helpful

The energy that cells need for cellular processes is found in the chemical bonds that make up ATP (adenosine triphosphate).

What is ATP?

ATP, or adenosine triphosphate, is a molecule that stores and provides energy for cellular processes. It is often referred to as the "energy currency" of the cell. ATP is composed of three phosphate groups, a sugar molecule (ribose), and a nitrogen-containing base (adenine).

The energy stored in the bonds between the phosphate groups is released when the last phosphate bond is broken, forming ADP (adenosine diphosphate) and a free phosphate group. This process, called hydrolysis, releases energy that is used by the cell to drive metabolic processes such as muscle contraction, nerve impulse transmission, and protein synthesis.

ATP is produced in the mitochondria through cellular respiration and is constantly recycled within the cell to provide energy for ongoing cellular processes.

What is the difference between a GMO and cloning



Please help if you know the answer please

Answers

Answer:

A GMO Genetically Modified Product though similar to cloning is quite different. Cloning is the process of using egg cells from an individual to produce a new organism. When the baby is born, it is genetically identical to the parent, an exact copy. This process occurs in a lab. Genetic Engineering, which is used to make GMOs,  uses technology to alter or change an organism's genes. New genetic information can be added to or removed from an existing set of DNA.

So I would say that some of the differences between GMOs and cloning include that:

Cloning strives to create exact copies of an organism's parent while GMOs remove and add different genes to form desired offsprings like making a product last longer or making the product grow larger faster.

Hopefully, this helped you! Have a nice day :)

c. dna is destroyed so it has no value

Answers

Answer:

b. multiple copies of the dna sample are made

Explanation:

Polymerase chain reaction (PCR) is a method used to make millions to billions of copies i.e. complete copies or partial copies of a specific DNA sample, allowing scientists to take a very small sample of DNA and amplify it. The new fragments of DNA that are synthesize during Polymerase chain reaction (PCR) also serve as templates to which the DNA polymerase enzyme can attach and start making DNA. The result of this attachment in a production of huge number of copies of the specific DNA segment in a short period of time.

Why is the genetic code common to all organisms!

Answers

Answer:

Why Is DNA Considered a Universal Genetic Code? DNA is considered a universal genetic code because every known living organism has genes made of DNA. ... All organisms also use DNA to transcribe RNA, and then they translate that RNA into proteins. Every living organism uses that same system.

Explanation:

The genetic code is universal because it is the same among all organisms. Replication is the process of copying a molecule of DNA. Transcription is the process of converting a specific sequence of DNA into RNA.

 

Protein-encoding genes specify the sequences of amino acids, which are the building blocks of proteins. In turn, proteins are responsible for orchestrating nearly every function of the cell. Both protein-encoding genes and the proteins that are their gene products are absolutely essential to life as we know it.

what is the meaning of
•molecule
•compound
•atom
•element
•organic compound
•inorganic compound​

Answers

Molecule: a molecule is the smallest particle in a chemical element or compound that has the chemical properties of that element or compound. Molecules are made up of two or more atoms that are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons among said atoms. Although oxygen is an element, it naturally has 2 atoms (O2), because it is a halogen and in order to reach 8 valence electrons and become stable and unreactive, it bonds with another oxygen atom. This means that oxygen atoms and oxygen molecules are different; one is an element, the other is a molecule.

Pure Substance: can be divided into two sub-categories: compounds and elements.

Compound: A chemical compound is a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds. A molecule consisting of atoms of only one element is therefore not a compound, meaning that oxygen molecules (O2) are NOT compounds. NaCl, or table salt, is.

Atom: An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms.

Element: An element is a pure substance consisting only of atoms that all have the same numbers of protons in their atomic nuclei. Elements are the base, more "pure" of the pure substances. Each element is assigned a symbol. Perhaps the most recognizable of them is H, for hydrogen.

Organic Compounds: organic compounds are generally any chemical compounds that contain carbon-hydrogen bonds. The study of these is called organic chemistry. I mean, carbon is the basis of ALL known life.

Inorganic Compounds: They are any substance in which two or more chemical elements (usually other than carbon) are combined, nearly always in definite proportions. Compounds of carbon are classified as organic when carbon is bound to hydrogen. THE OPPOSITE OF ORGANIC COMPOUNDS.
