A gardener cut her finger while pruning shrubs. She noticed that after two weeks the wounds had nearly healed with just a small scar remaining. Which statement describes what will happen next?
A. Each one of the individual cells near the wound will grow in size to cover the injured part.
B. Cells will be transported from distant areas to the wound to cover the injured area.
C. The cells near the wound will produce identical cells by mitosis to repair the damaged tissues.
D. A material will be released by the injured cells that will cover the wound and repair the cells.
Answer:
c
Explanation:
The wound will be healed by the production of new cells near the wound by the cell replication process and the therefore the identical cells are produced by the mitosis to repair the damaged tissues.
Note the below points about mitosis;
The mitosis is a process in which the cell replication occurs.In mitosis, the single parent cell is divided into two identical daughter cells by the process of cell division, it takes by time.The mitosis involves the healing of wound, growth of the organisms, replacement of the worn out cells.Thus, mitosis is the process involved in the healing of wound in living beings.
Therefore, we can say that the answer of the question is C. The cells near the wound will produce identical cells by mitosis to repair the damaged tissues.

You now have these half-reaction equations:
3e + HNO3 → NO
S→ H2SO4 + 6e
Which factor will you use for the top equation?
Which factor will you use for the bottom equation?
Explanation:
The two half equations are;
3e + HNO3 → NO
S→ H2SO4 + 6e
When balancing half equations, we have to make sure the number of electrons gained is equal to the number of electrons lost.
Which factor will you use for the top equation?
We multiply by 2 to make the number of electrons = 6e
Which factor will you use for the bottom equation?
We multiply by 1 to make the number of electrons = 6e

9. If 1,785 cal of heat is added to a 343 g sample of water (specific heat = 4.18J/g °C) at 1202,
what is the *final temperature of the water? *
(1 Point)
15.76°C
031'c
18.24°C
1.24°C
Answer:
17.21°C
Explanation:
Using the following formula;
Q = m × c × ∆T
Where;
Q = amount of heat in joules
m = mass of substance in grams
c = specific heat capacity of water (4.184 J/g°C)
∆T = final temperature - initial temperature
According to the information provided in this question,
Q = 1,785 cal
1 cal = 4.184 J
1785 cal = 7468.4J
m = 343grams
c = 4.18J/g °C
initial temperature = 12°C
Using Q = m × c × ∆T
7468.4 = 343 × 4.18 × (T - 12)
7468.4 = 1433.74(T - 12)
7468.4 = 1433.74T - 17204.88
7468.4 + 17204.88 = 1433.74T
24673.28 = 1433.74T
T = 24673.28 ÷ 1433.74
T = 17.21°C
If the pressure of a gas at constant volume is 4.5 atm at 100 °C, wh
will the pressure be if the temperature is changed to 350 °C?
Answer:
New pressure = 7.51 atm
Explanation:
Given that,
Initial pressure, P₁ = 4.5 atm
Initial temperature, T₁ = 100°C = 100+273 = 373 K
Final temperature, T₂ = 350°C = 350 + 273 = 623 K
We need to find the new pressure. Using the below relation as follows :
[tex]\dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}\\\\P_2=\dfrac{P_1T_2}{T_1}\\\\P_2=\dfrac{4.5\times 623}{373}\\\\P_2=7.51\ atm[/tex]
So, the new pressure is 7.51 atm.

At a constant temperature the pressure on a 10.0L sample of gas is charged from 1140 torr to 1.00 atm. What is the new volume of gas sample?
Answer:
15 L
Explanation:
From the question given above, the following data were obtained:
Initial volume (V₁) = 10 L
Initial pressure (P₁) = 1140 torr
Final pressure (P₂) = 1 atm
Final volume (V₂) =?
Recall:
1 atm = 760 torr
The new (i.e final) volume of the gas can be obtained as follow:
Initial volume (V₁) = 10 L
Initial pressure (P₁) = 1140 torr
Final pressure (P₂) = 760 torr
Final volume (V₂) =?
P₁V₁ = P₂V₂
1140 × 10 = 760 × V₂
11400 = 760 × V₂
Divide both side by 760
V₂ = 11400 / 760
V₂ = 15 L
Therefore, the new volume of the gas is 15 L

What type of molecule would deviate the most from ideal gas behavior?
Answer:
molecule at low temperature and high pressure
Explanation:
this is because two of the postulates of kinetic theory of gases hold true only when there is low pressure and high temperature. as the pressure goes on increasing and temperature goes on decreasing, a molecule will deviate from ideal behavior.
The _________ force between the sun and the Earth keeps the Earth in its orbit. The period of ______ is the time it takes for Earth to complete one orbit.
Question 1 options:
revolution, gravitational
rotate, gravitational
gravitational, rotate
gravitational, revolution
Gravitational force is the force between the sun and the Earth keeps the Earth in its orbit. The period of revolution is the time it takes for Earth to complete one orbit.
What is gravitational force?Gravitational force is a kind of attraction force which acts between the two bodies.
Sun's gravitational force is a 3 dimensional attraction force under which earth is present. And due to centripetal force of sun, orbit of earth is present in the stationary state. Earth revolves around the sun to complete one round of orbit and this motion is known as revolution of earth.
Hence, gravitational force is present between the sun and the earth, and revolution is the time to complete one orbit.

“Nature vs. nurture” is a debate about
A
whether a trait is learned or inherited.
B
the traits of plants vs. the traits of animals.
с
whether animals can teach humans new traits.
D
whether a trait was acquired outdoors or indoors.
Answer:
Letter A
whether a trait is learned or inherited
Explanation:
The nature versus nurture debate involves the extent to which particular aspects of behavior are a product of either inherited (i.e., genetic) or acquired (i.e., learned) influences. Nature is what we think of as pre-wiring and is influenced by genetic inheritance and other biological factors.
The debate called Nature vs. nurture is about whether a trait is learned or inherited. This is an investigation on learned traits and nurtured traits in humans. Thus option A is correct.
What are learned traits ?All living things are learning something during their growth. These learning mold up one's personality and cannot be created by birth. Like the good characteristics we are learning from schools. These behaviors are called learned traits.
Some traits or behaviors are created by birth itself and they are called natural traits. The nature versus. nurture debate is a philosophical, scientific, and cultural discussion about whether human culture, conduct, and personality are largely influenced by nature or nurture.
Environment, culture, and experience are the most prominent definitions of nurture in this discussion, whereas nature is frequently regarded as genetic or hormone-based behaviors, characteristics, and dispositions.

how does latitude affect the temperature in an area
Answer:
Latitudes are used to indicate a precise location of any feature on the earth's surface.
Temperature changes with latitudes .At higher latitudes, the Sun's rays are less direct. The farther an area is from the Equator, the lower its temperature. At the poles, the Sun's rays are least direct.Near the equator sun's rays are perpendicular resulting into very high temperatures. Generally, around the world, it gets warmer towards the equator and cooler towards the poles.
