digestive system is important for human body why?
Answer:
Why is digestion important? Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body.

which of a-d below is an example of diffusion, osmosis, or neither? Explain your answer in each case. a Water moves from a dilute solution in the soil into the cells in a plant's roots. b Saliva flows out of the salivary glands into your mouth. c spot of blue ink dropped into a glass of still water quickly colours all the water blue. d Carbon dioxide goes into a plant's leaves when it is photosynthesising.
Answer:
a. osmosis (water must pass through the cell membrane so it is osmosis) b. neither (the saliva is secreted) c. diffusion (the dye doesn't pass through a membrane) d. diffusion"
Explanation:
I'm not sure, but I hope it helps.
The examples of diffusion, osmosis, or neither are as follows:
Water moves from a dilute solution in the soil into the cells in a plant's roots: Osmosis.Saliva flows out of the salivary glands into your mouth: Neither.A spot of blue ink dropped into a glass of still water quickly colors all the water blue: Diffusion. Carbon dioxide goes into a plant's leaves when it is photosynthesizing: Diffusion. What is Diffusion?Diffusion may be defined as the process through which the migration of individual molecules of a substance through a semipermeable barrier from a region of higher concentration to a region of lower concentration.
While osmosis significantly involves the migration of solvent molecules from a region of lower solute concentration to a region of higher solute concentration through a semi-permeable membrane. Osmosis is thought to be the opposite of diffusion with respect to the definitions.
Therefore, the examples of diffusion, osmosis, or neither are well described above.

How high is the ceiling in a school gym if a volleyball thrown upward from the floor at 15 m/s barely touches the ceiling before returning to the ground?
Answer:
11.47 m
Explanation:
Givens
vi = 15 m/s
a = - 9.81 m/s^2
vf = 0
d = ?
Formula
vf^2 = vi^2 + 2ad
Solution
0 = (15)^2 + 2*(-9.81)*d
- 225 = 2 * - 9.81 *d
-225 = - 19.62 * d
d = - 225/-19.62
d = 11.47 m
The height of the ceiling in the school gym from the floor is 11.48m.
HOW TO CALCULATE HEIGHT OF A PROJECTILE:
Using one of the equations of motion as follows:v² = u² + 2as
Where;
v = final velocity (m/s)
u = initial velocity (m/s)
a = gravitational acceleration (m/s²)
s = distance traveled (m)
According to this question,
The final velocity (v) of the volleyball is 15m/sThe initial velocity is 0m/sThe acceleration due to gravity is 9.8m/sUsing the formula, v² = u² + 2as, the height of the ceiling (s) can be calculated as follows:
15² = 0² + 2 (9.8) (s)
225 = 0 + 19.6s
225 = 19.6s
s = 225/19.6
s = 11.48m
Therefore, the height of the ceiling in the school gym from the floor is 11.48m

Signal transduction pathways that include a phosphorylation cascade
are generally initiated by a phosphorylase enzyme and limited to one step
are generally inactivated by a kinase enzyme and decrease signal transduction efficiency
are propagated by steroid hormone receptors to reach the final cellular response in one step
cause a structural change in each phosphorylated protein, with the addition of a phosphate group to activate the protein
Answer:
Signal transmission paths Learn how signals are transmitted within a cell from the cell membrane receptor. The chains of molecules that pass intracellular signals are known as intracellular signal transduction pathways.
Signal transduction pathways that include a phosphorylation cascade cause a structural change in each phosphorylated protein, with the addition of a phosphate group to activate the protein. Thus, the correct option for this question is D.
What is the Phosphorylation cascade?The Phosphorylation cascade may be characterized as a series of signaling pathways that significantly involve the activation of one enzyme through the effect of other in order to accomplish the downstream signaling pathway.
According to the context of this question, the process of phosphorylation involves the addition of a phosphate group over the compound in order to stimulate its activity. This is accomplished by the structural change in each phosphorylated protein, with the addition of a phosphate group to activate the protein.
Therefore, the correct option for this question is D.

A. They are connected to bones.
B. They allow voluntary movement.
C. They allow us to move.
D. They are connected by gap junctions.
The one that is not true regarding muscular system is that they are connected by gap junction. The correct option is D.
What is gap junction?Gap junctions are specialized intercellular connections that connect a wide variety of animal cell types.
They connect the cytoplasm of two cells directly, allowing molecules, ions, and electrical impulses to pass through a regulated gate between cells.
Location includes that the gap junctions can be found in a variety of locations throughout the body.
This includes epithelia (surface coverings of the body), nerves, cardiac (heart) muscle, and smooth muscle (such as that of the intestines). Their primary function is to coordinate the activity of neighboring cells.
Skeletal muscle cells lack gap junctions because they do not require them. Skeletal muscles are not made up of individual cells.
Thus, the correct option is D.

7. To test a new voice feature in a cockpit design a flight simulator was used. The simulator was programmed to
give visual readings of flight information, or to give visual and auditory (voice) readings of flight information. All
test pilots were put through a simulated emergency landing procedure, but were randomly assigned to the
visual, or visual and auditory conditions. Flight experts rated each pilot's performance in the simulator on a
scale of 1 (very poor) to 10 (excellent).
The variables in the simulation procedure carried out are :
Independent variable = Simulator Independent variable = Simulator Dependent variable = PerformanceThe dependent and independent variables are critical in any experimental study as both variables encompasses the variable to be measured and the variables manipulated in other to obtain the variable to be measured.
Independent variable : This is also called the predictor variable which is tweaked in other to obtain changes in the measured or dependent variable. In the experiment performed, the simulator is the independent variable has it has different visual or visual and auditory conditions capable of causing changes to the performance rating. The dependent variable is the variable being measured in an experiment. In this case, it is PERFORMANCE.
