Answer:
If a linear graph has a negative slope then dependent value decreases in value as the independent variable increases. The line with negative slope is sloping down to the right
Answer:
The correct answer is - 1/4096.
Explanation:
In the starting, there is that the number of atoms is N
0
.
The number of half-lives in this case, = 300/ 25 = 12
After the first half-lives or 25 days, N
1
=
N
0
/2
the half life is that time where half of the sample had decay.
After the second half-life or 50 days, N
2
=
N
1
/2 =
N
0
/4
.
There is division by two the original amount, then after four times you divide four times for 2 that means that you divide by 2
^12 =4096
.
So the final amount remain is N
12
=
N
0
/4096 or 1/4096.
Answer:
Cell membrane
B

Capsules, fimbriae, pili, flagella, and even the cell wall
Answer is: 4. it increases the average kinetic energy and there are more collisions per minute.
The average kinetic energy of molecules depends on the temperature.
As temperature increases, molecules gain more energy from surrounding and move faster and have more collisions.
Kinetic energy (standard unit is the joule J) depends on speed of the molecule.
The collision theory states that when suitable particles of the reactant hit each other, only a certain fraction of the collisions cause any noticeable or significant chemical change. These successful changes are called successful collisions.
