If eukaryotes all came about due to endosymbiosis, what would result from that?
Endosymbiosis occurs when larger prokaryotes envelop prokaryotes that perform aerobic metabolism (later known as mitochondria) and prokaryotic cells that do photosynthesis.
These "now" mitochondrion's "came to realise" that they really can not live without the bigger prokaryotes that swallowed them, and therefore they stayed with them.

Which of the following is NOT true of the
muscular system?
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.

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

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.
