Fermentation is a chemical process by which molecules such as glucose are broken down anaerobically. Therefore, option (A) is correct.
What do you mean by fermentation?Fermentation is a metabolic process that produces chemical changes in organic substrates through the action of enzymes. In biochemistry, it is narrowly defined as the extraction of energy from carbohydrates in the absence of oxygen.
Moreover, fermentation occurs in the absence of oxygen (anaerobic conditions), and in the presence of beneficial microorganisms (yeasts, molds, and bacteria) that obtain their energy through fermentation.
Hence, fermentation reactions occur in the cytoplasm of both prokaryotic and eukaryotic cells. In the absence of oxygen, pyruvate does not enter the mitochondria in eukaryotic cells.

If you cook a pizza on a metal tray, you place the pizza on the tray at room temperature. This is placed in a hot oven. Once cooked, you remove the tray from the oven. Eventually the tray reaches room temperature again. Describe and explain what happens to the motion of the particles in the metal tray.
Answers
Answer: 1. particles vibrate
more
2. individual particles do not
get ( change their temperature).
3. They vibrate less and become
motionless
Explanation:
when the tray is placed in the oven,the particles get heated ( this results in a change in temperature.) as the temperature increases so does their kinetic energy. What this simply implies is that the particles would tend to vibrate more vigorously than before.
When you remove the tray from the oven it’s temperature decreases, so also is it’s kinetic energy. This makes the particles to vibrate slowly and become motionless.
A Egg is ....
A. Element
B. Composite
C. Homogeneous mixtures
D. Heterogeneous mixtures
Answers
Answer:
Element
Explanation:
Answer:
D. Heterogeneous mixtures
Explanation:
An egg (raw egg) is naturally made up of the egg white and the egg yolk. It is a heterogenous mixture because you can separate the egg white from the egg yolk. This is commonly done in baking. Its composition is non-uniform.
It becomes a "homogenous mixture" once you beat the egg. In this situation, you won't be able to separate the egg white from the egg yolk anymore.

33
90
96
Answers
Answer:
3 nucleotide require to produce one amino acid.As 30 amino acid , it requires 90 nucleotides including start codon but a polypeptide chain have a stop codon at last therefore 93 nucleotide will make up the coding mRNA strand.
The stop codon may be UAA ,UAG ,UGA they encode no amino acid.
One amino acid requires 3 nucleotides. The coding mRNA strand will have 93 nucleotides since a polypeptide chain has a stop codon at the end of 30 amino acids. Therefore, option (A) is correct.
What are codons?A segment of three adjacent nucleotides within a DNA or RNA molecule that, when read, denotes the presence of a particular amino acid. There are particular codons that indicate the beginning or end of the translation process.
3 nucleotide require to generate one amino acid. As 30 amino acids, it requires 90 nucleotides including a start codon, but a polypeptide chain also has a stop codon at the end; as a result, the coding mRNA strand will have 93 nucleotides.
The stop codon could be UAA, UAG, or UGA; however, none of these codons encode an amino acid.

A. Limestone
B. Amazon rain forest
C. Fossil fuels
D. Atlantic Ocean
Answers
From the options The Largest carbon reservoirs on earth is : ( A ) Limestone
The Largest carbon reservoirs on earth includes the Earth crust ,Oceans and fossil fuels. Limestone makes up about 15% of the earth's crust ( sedimentary ) therefore it is the largest carbon reservoir out of all the options given above.
Limestones are used as raw materials for the production of cement and other building/construction materials.
The Earth crust contains about 50,000,000 g/tons of Carbon in total while the oceans contain about 40,000 g/tons of carbon which is followed by Fossil fuels at 10,000 g/tons

The honeycomb-like appearance of this sandstone is a result of frost wedging, hence option D is correct.
What is frost wedging?Wedging Repeated freezing results in a freeze. When the water turns into ice due to the 9 percent expansion, freeze wedging happens. Water-filled fissures are compelled to further divide when it freezes, and other choices, which can be characterized as follows, are erroneous
0xidation is incorrect since the element is in a state where it transforms into a liquid. Hydrolysis is incorrect since it is a reaction in which the bonds of water are broken down into a specific chemical.
Salt weathering is incorrect since it refers to a type of mechanical or physical rock weathering.

Do you think different sources of carbs (sugars) would affect
the rate of fermentation in yeast? Why or why not?
Answers
Yeast can use oxygen to release the energy from sugar (like you can) in the process called "respiration". So, the more sugar there is, the more active the yeast will be and the faster its growth (up to a certain point - even yeast cannot grow in very strong sugar - such as honey).
However, if oxygen is short (like in the middle of a ball of dough), then yeast can still release energy from sugar, but in these conditions, its byproducts are alcohol and carbon dioxide. It is this carbon dioxide gas which makes the bubbles in dough (and therefore in bread), causing the dough to rise.
Alcohol is a poison (for yeast as well as for people) and so the yeast is not able to grow when the alcohol content gets too high. This is why wine is never more than about 12% alcohol.

The Mantle
I hope this helps
The mantle is the part which is the most similar to the sun’s convection zone. It is the second layer of Earth.
Which layer from Earth's atmosphere is convective in nature ?It is the troposphere that is convective in nature. Troposphere means the region of mixing.
The mantle is the most similar to sun's convection zone. Sun's convection zone is later dominated by the convection currents that carries energy outward to surface. Mantle is second layer of Earth.
The zone is not that dense enough to just use the radiative transfer of the energy, infact , they uses the thermal convection zones in just other words then it boils. Energy is then carried out through the thermal columns to surface of sun and later creates out areas that are seen as the solar granulation and the super granulation.
