How do mechanical and chemical digestion work together to break down food

Physics

Anastasy [175]4 years ago
6 0

Answer:

Explanation:

Digestion is the breaking down of food in order to release energy for the body. The body obtains its required nutrients through the process of digestion. In digestion, food is broken down and energy is released.

Mechanical digestion involves the breakage of food into tiny bits. Chemical digestion uses chemicals secreted in the body to completely and finally breakdown food.

Mechanical digestion helps the course of chemical digestion. In mechanical digestion, food is broken down by chewing, cudding, churning e.t.c. Here large chunks of food are broken down into tiny bits. The tiny fragments of food has more surface area than the bulk mass. Increase in surface area makes chemical reactions on food very fast. As the food is being subjected to mechanical breakage, chemical action takes place simultaneously.

The food being broken would then be mixed with chemical substances in the body for proper breakage. Chemical digestion completes the digestive process. Chemically digested food can easily be taken into the blood stream where they are transported to different sites within the body.

Scilla [17]

Answer:

The correct answer is - A matter that has an ordered arrangement of atoms, molecules, or ions.

Explanation:

In physics, a crystal is a type of solid matter in which a highly arranged molecule or atoms present to form a lattice that extended in all directions. It is a lightweight clear solid which is normally is colorless.

It can be cubic, hexagonal, triclinic, monoclinic, orthorhombic, tetragonal, and trigonal that are ordered arrangments. Its internal symmetry is visible to its surface.

The horizontal bar rises at a constant rate of three hundred mm/s causing peg P to ride in the quarter circular slot. When coord
SVETLANKA909090 [29]

Answer:

Explanation:

Given

Horizontal bar rises with 300 mm/s

Let us take the horizontal component of P be

P_x=rcos\theta

P_y=rsin\theta

where \thetais angle made by horizontal bar with x axis

Velocity at y=150 mm

150=300sin\theta

thus \theta =30^{\circ}

position ofP_x=rcos\theta =300\cdot cos30=300\times \frac{\sqrt{3}}{2}

P_x=259.80 mm

P=259.80\hat{i}+150\hat{j}

Velocity at this instant

u_x=-rsin\theta =300\times sin30=-150 mm/s

u_y=rcos\theta =300\times cos30=259.80 mm/s

two coins lie 1.5 meters apart on a table. they carry identical electric charges. approximately how largeis the charge on each c
BARSIC [14]

The charge on each coin is equal to

Given the following data:

Force = 2.0 Newton

Radius = 1.5 meters

To determine the charge on each coin, we would apply the law of electrostatic forces:

Mathematically, the law of electrostatic forces is given by the formula:

Note:  (since the coin carry identical electric charges).

Therefore, the formula becomes:

Making q the subject of formula, we have:

Substituting the given parameters into the formula, we have;
