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.

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).

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.

Explanation:

Mesopotamia has been the Western Asian region that is known for early civilization. The method that has the least impact on the water table is the best irrigation method. Thus, option B is correct.

Mesopotamian irrigation practices have been the use of canals and shadufs for direct use in agricultural fields. They irrigated their land by digging holes and storing the water. They also built canals and connected them to the ditches.

For modern practices, the Mesopotamian irrigation system is a model as it defines the best irrigation method to be the one that has the least impact on the water content and table.

Therefore, option B. the best irrigation method is that uses the eater most efficiently and does not negatively impact the water table.

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.

Explanation:

Just did it

The trapped carbon dioxide causes the dough to rise, evidence of a chemical change in Michael's bread-making process.

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.
