HURRY! Michael decides to bake bread one morning. He measures ingredients, mixes them together to make a dough, and cooks the dough in an oven. As the dough cook's, Michael observes the bread rising. Which of the following is evidence of the chemical change in Michael’s bread-making process?
Answers
Answer:
The bread rising as carbon dioxide is released.
Explanation:
Just did it
The trapped carbon dioxide causes the dough to rise, evidence of a chemical change in Michael's bread-making process.
What is Fermentation?Fermentation is defined as a metabolic process that produces chemical changes in organic substrates through the action of enzymes which is narrowly defined as the extraction of energy from carbohydrates in the absence of oxygen.
Microorganisms such as bacteria and fungi have metabolic genes that allow them to produce enzymes to break down a variety of sugar metabolites.
Yeast and sugar produce carbonic gas through fermentation which is why as the yeast consumes the sugar, it produces alcohol (ethanol) and carbonic gas (carbon dioxide) as waste products, hence the carbon dioxide trapped in the dough lifts up,
Thus, the trapped carbon dioxide causes the dough to rise, evidence of a chemical change in Michael's bread-making process.

C. peripheral nervous system
D. central nervous system
Will mark brainlest for quick and correct answer
Answers
Answer:
The CNS
Explanation:
First, the entire CNS is enclosed in bone. The brain is protected by the skull, while the spinal cord is protected by the vertebra of the spinal column. The brain and spinal cord are both covered with a protective tissue known as meninges.
The nervous system has been the most crucial organ system that acts as the command center. The CNS of the nervous system is very well protected by the bones. Thus, option D is correct.
What is CNS?CNS has been abbreviated for the central nervous system which comprises the spinal cord and the brain. The spinal cord is located at the dorsal surface and the brain is at the anterior location of the body.
The CNS has been enclosed by the skeletal system as the spinal cord is confined inside the vertebral column and the brain inside the skull. They have cerebrospinal fluid that acts as the cushion that protects these structures from shock and injuries.
Therefore, option D. CNS has been the part of the nervous system that is protected by the skeletal system (bones).

James adds some magnetic marbles to a glass jar full of ordinary marbles, and then shakes up the jar. What do you think will happen to the magnetic marbles?
Answers
Answer:
Magnetic marbles will tend to attract each other.
Explanation:
Magnetic marbles are composed of ferromagnetic materials, which indicates that they function as a magnet and have the ability to attract other objects formed by ferromagnetic materials. In this case, we can say that the magnetic marbles attract each other and inside a jar containing magnetic marbles and common balls, the magnetic marbles will tend to attract and group together.
When James shakes the glass jar ; The magnetic marbles will attract each other
The magnetic marbles will attract each other because of the ferromagnetic materials that each magnetic marble contains. marble is a rock ( metamorphic ) that is made up mainly of calcium carbonate .
when rocks/compounds contain ferromagnetic materials they will act as magnets thereby attracting any metallic object or any magnetic material within close proximity. therefore the magnetic marble will attract each other inside the glass jar
Hence we can conclude that When James shakes the glass jar ; The magnetic marbles will attract each other.

You are required to make 10mL of a 0.5M solution of HCl. Your stock solution of HCl is 90M. Using distilled water (dH2O) as a solvent, how much of each component will you need to make the desired final solution?
Answers
Answer:
0.0556 mL of 90 M HCl would be taken and 9.944 mL distilled water added to make 0.5 M, 10 mL HCl solution.
Explanation:
From the dilution equation:
Initial molarity (m1) x initial volume (v1) = final molarity (m2) x final volume (v2).
In this case, m1 = 90 M, v1 = ?, m2 = 0.5 M, and v2 = 10 mL
v1 = m2 x v2/ m1 = 0.5 x 0.01/90 = 0.0000556 L
v1 = 0.0556 mL
This means that the initial volume of 90 M HCl to be taken is 0.0556 mL. Since the final volume to be prepared is 10 mL,
10 - 0.0556 = 9.944 mL
Hence, 0.0556 mL of 90 M HCl would be taken and 9.944 mL distilled water added to make 0.5 M, 10 mL HCl solution.

Every cell in the body is enclosed by a cell (Plasma) membrane. The cell membrane separates the material outside the cell, extracellular, from the material inside the cell, intracellular. It maintains the integrity of a cell and controls passage of materials into and out of the cell.
The molecule that separates the contents inside of the cell from the contents outside of the cell is LIPIDS.
Lipids represent a broad range of biomolecules made up of carbon (C), hydrogen (H) and oxygen (O) atoms.In some cases, lipids also contain phosphorus (P), nitrogen (N) or sulfur (S).Lipids (i.e., phospholipids and cholesterol) represent the main biomolecules of the cell membrane whose function is to separate the interior of the cell from its surrounding environment.In conclusion, the molecule that separates the contents inside of the cell from the contents outside of the cell is LIPIDS.
