Does adding or taking away a proton change the identity of the element? Yes or no
Answer:
yes
Explanation:
The identity of an element is determined by the number of protons. One cannot alter the number of protons without altering the identity of the element. By adding a proton, the atomic number increases by one and the element identity changes. Number of neutrons can be altered to create isotopes.
Answer:
Yes
Explanation:
Protons carry a positive electrical charge and they alone determine the charge of the nucleus. Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom's atomic number. So, adding or removing protons from the nucleus changes what element that atom is!

Two students were having a discussion about viruses.
Student A believes viruses are not living organisms .
Student B believes viruses are living organisms.
Which student is correct and why?
Student A is RIGHT because viruses are not living organisms.
All living organisms are composed of cells, and viruses do not have cells (they only have protein coats that protect their genetic material).Viruses are entities that need to parasite the cells of different host organisms to survive.In consequence, a virus cannot replicate in absence of a suitable host cell.In conclusion, student A is RIGHT because viruses are not living organisms.

Place in order the correct sequence by which water flows through plants
1. transpiration from the leaves
2. absorption from the soil by root hairs
3. movement from roots to stem
4. flow upwards in the stem
Answer:
The correct sequence is - 2, 3, 4, 1.
Explanation:
The movement of the water takes place in the plant from the soil and moves up to leaves and from there to the atmosphere. Root hairs help in the absorption of the water from the soil with help of the epidermis of root hairs. Water then takes the path from the root to the stem with help of cortical cells.
Once the water reaches the endodermis or endodermal cell the water freely flow in the xylem cell upwards the stem moves to leaves by the transpiration stream. In the process of transpiration, an excess amount of water evaporates into the atmosphere.

While pushing a wagon around the park steve applies a force of 100n along thd handlr which makes 32cangle with the ground if he pushes it 25 metree how much wrk dods he fo
Answer:
Workdone = 2120 Joules.
Explanation:
Given the following data;
Force applied = 100N
Angle = 32°
Distance = 25m
To find the workdone by Steve, we would first of all find the horizontal component of the force applied.
[tex] Horizontal force, Fx = mgCosd[/tex]
Where;
Fx represents the horizontal force.
m is the mass of an object.
g is the acceleration due to gravity.
d is the angle of inclination (theta).
mg = weight = 100N
Substituting into the equation, we have;
[tex] Fx = 100 * Cos32[/tex]
[tex] Fx = 100 * 0.8480[/tex]
Fx = 84.80N
Workdone is given by the formula;
[tex] Workdone = force * distance[/tex]
Substituting into the equation, we have;
[tex] Workdone = 84.80 * 25 [/tex]
Workdone = 2120 Joules.

2. Once the solution across a membrane does in fact reach equilibrium, the molecules in solution will
A. move across the membrane to the outside of the cell.
B. completely stop moving across the membrane.
C. continue to move across the membrane in both directions.
D. move across the membrane to the inside of the cell.
Answer:
B
Explanation:
Molecules and ions diffuse through cell membrane due to a concentration gradient. But, once the equilibrium is achieved between inside and outside the cell, molecules stop moving. Thus, option B is correct.
What is cell membrane?Cell membrane is an organelle surrounding the cell which facilitates the transportation of ions and molecules, inside and outside the cell. To maintain an ionic balance is important in metabolism of living things.
Ions such as sodium and potassium are balanced by a mechanism called sodium -potassium pump. The sodium ions outside the cell is greater than that of inside.
Similarly calcium pump works for calcium and magnesium. The concentration gradient of these ions make this flow of ions across cell membrane. Hence, once they achieve equilibrium the flow will stop and no ions will be transported across the membrane.

How would you compare a circle to an ellipse?
Answer:
A circle is a closed curved shape that is flat. ... Instead of having all points the same distance from the center point, though, an ellipse is shaped so that when you add together the distances from two points inside the ellipse (called the foci) they always add up to the same number.
