Solid because it maintains their shape and is rigid 
in this case the answer would be letter "D"

Answer:

Solid

Explanation:

Solid phase of matter is characterized by presence of less or no space between its particles. The atoms of the molecules are placed close to each other and are bonded together. Absence of gaps and tight bonding does not allow the particles of the substance to move part each other and results in rigidity and fixed shape.

Complete question: The chart shows the movement of a ball after several seconds.

Column A is on the x-axis, and Column B is on the y-axis. Which titles should replace A and B?

a. Column A should be “Time,” and Column B should be “Position.”

b. Column A should be “Position,” and Column B should be “Time.”

c. Column A should be “Velocity,” and Column B should be “Speed.”

d. Column A should be “Speed,” and Column B should be “Velocity.”

Answer:

Column A should be "Time," and Column B should be  "Position"

Explanation:

In general, the first column always refers to the x-axis, this is the independent variables. While the second column refers to the y-axis, the dependent variables.

Option A) names Time and Position to the columns. This seems to be correct as time is an independent variable, while the ball position depends on time. The x-axes is named "time", and the Y-axes is named "ball position".

Option B) is not possible because the Position is not the independent variable, and time is not the dependent variable.

Option C) and D) are not possible, as both of them are variables that depend on time.

<h2>Transportation across the membrane</h2>

Explanation:

(a) Simple diffusion; Faciliated diffusion-Directions in which two transported solutes move

  • In simple diffusion diffusion of non polar compounds across the membrane and along the concentration gradient without the involvement of protein whereas in case of facilitated diffusion membrane transport proteins that facilitate movement pf molecules across the membrane down its concentration gradient
  • Both the diffusions does not require energy

(b) Facilitated diffusion; active transport-Direction the solute moves relative to its concentration gradient

  • In facilitated diffusion membrane transport proteins that facilitate movement of molecules across the membrane down its concentration gradient without the expenditure of energy
  • Active transport drives transportation of solute against the concentration gradient across the membrane

(c) Simple diffusion; Active transport-Directions in which two transported solutes move and Direction the solute moves relative to its concentration gradient

  • In simple diffusion diffusion of non polar compouds across the membrane and along the concentration gradient without the involvement of protein and energy
  • Active transport drives transportation of solute against the concentration gradient across the membrane;secondary active transporters coupled with transportation of two solute molecules

(d) Direct active transport; Indirect active transport-Direction the solute moves relative to its concentration gradient or its electrochemical potential

  • Direct active transport use direct energy such as ATP hydrolysis,oxidation and sunlight energy
  • Indirect active transport use indirect energy such as chemical gradient,electrochemical gradient established by direct active transporters;one solute moves along the concentration gradient while other moves against the concentration gradient

(e) Symport; Antiport-Direction in which two transported solutes move

  • In symport both the solute molecules move in same direction;coupled with primary active transport(direct transport)
  • In antiport both the solutes moves in opposite direction;coupled with secondary active transport(indirect transport)

(f) Uniport; coupled transport-Directions in which two transported solutes move

  • Uniport is the transport of single solute across the membrane
  • Coupled transport is the transport of two solute molecules across the membrane;it may be symport or antiport

(g) P-type ATPase; V-type ATPase-Kinetics of solute transport

  • P-type ATPase always transport cations and undergoes phosphorylation
  • V-type ATPase(here V stands for vacuole) transport protons and no phosphorylation occurs;catalytic activity is not reversible
  • Both are types of primary active transporters

What does the quote "science is the key to success and if you don't believe in science then you're holding everybody back ." Mea
Studentka2010 [4]

Answer: Every person needs to have at least a simple understanding of the world in which they live, but if you don't have any factual evidence for your beliefs, then that will just confuse you and anyone else. Your ignorance can hinder a persons ability to learn whats factual, especially if you have an " I'm right and your wrong." personality.
