The process by which the organisms give rise to offspring is defined as the reproduction. It is mainly of two types, they are sexual and asexual. The daughter cell DNA is identical to the DNA from the parent cell in asexual reproduction. The correct option is A.
What is asexual reproduction?The mode of reproduction in which a new offspring is produced by a single parent is defined as the asexual reproduction. The newly formed individuals are genetically and physically identical to each other. They are called the clones of their parents.
Asexual reproduction occurs in both unicellular and multicellular organisms. This process does not involve any kind of gamete fusion and there is no change in the number of chromosomes either. It will obviously inherit the same genes as the parent.
In asexual reproduction, single parent is involved, the offspring is genetically similar, and this process occurs in a very short time.
Thus the correct option is A.

a metal with a mass of 1.00 kg occupies a volume of 370cm3. calculate the density of the metal.
Answer:
370 cm^3
Explanation:
Here, Density= Mass / Volume
=1.00/370
=370 cm^3.
The density of the metal is approximately 2.70 kg/dm³.
Density (ρ) is calculated by dividing the mass (m) of an object by its volume (V): ρ = m/V.
Given:
Mass (m) = 1.00 kg
Volume (V) = 370 cm³ = 0.370 dm³
Density (ρ) = 1.00 kg / 0.370 dm³ ≈ 2.70 kg/dm³
The density of the metal is approximately 2.70 kg/dm³.
Density is a measure of how much mass is contained within a given volume. In this case, a metal with a mass of 1.00 kg occupies a volume of 370 cm³.
By dividing the mass by the volume, the density is calculated. The resulting value of 2.70 kg/dm³ indicates that for every cubic decimeter (dm³) of volume, the metal has a mass of 2.70 kg.

i. 2 SnO2 + 4 H2 2 Sn + 4 H2O
ii. SnO2 + 2 H2 Sn + 2 H2O
a) Both equation I and II are balanced, but equation I is the correct way to write the balanced equation.
b) Can you divide equation II by another factor and still have it be correct? Why or why not?
c) In a complete sentence, write down a method you could use to determine if an equation is written in the correct way.
1. We have to divide the coefficient of equation I by 2 to get equation II.
a. Both equations are balanced but equation II is the correct way to write a
balance equation.
b. It will be correct if we divide equation II coefficient by another factor
but we will get fractions as coefficient. For example
[tex]\frac{1}{2}[/tex]SnO₂ + H₂→ [tex]\frac{1}{2}[/tex]Sn + H₂O
c. The correct method is checking if the number of moles of element on
the reactant side is same as the those on the product side. And the
conventional way is making sure the coefficients are whole numbers.
i. 2SnO₂ + 4H₂ → 2 Sn + 4H₂O
ii. SnO₂ + 2H₂→ Sn + 2H₂O
We have to divide the coefficient of equation I by 2 to get equation II.
Both equations are balanced but equation II is the correct way to write a
balance equation.
If we divide the coefficients of equation II by another number, we will not
get a whole number coefficients. The coefficient will be fractions , it will
be correct but its not conventional.
The best method to know if equation is written the correct way is checking
if the coefficient are in the lowest whole number factors.
we also have to check if each moles of elements found in the reactant is
the same in the product side.

0.12 L of oxygen gas is collected over water at 30∘C with a total pressure of 392 torr. What is the partial pressure of the oxygen?
The partial pressure of the oxygen in the sample of oxygen gas collected over water is 360.2 torr.
According to Dalton's law of partial pressure, the total pressure of a mixture of gases is the sum of partial pressures of all the gases in the mixture. From Dalton's law;
PT = P1 + P2 + P3 + ..........
The partial pressure of water at 30∘C is 31.8 torr, Hence;
Total pressure = Partial pressure of oxygen + Vapor pressure of water
Total pressure = 392 torr
Partial pressure of oxygen = Total pressure - Vapor pressure of water
Partial pressure of oxygen = 392 torr - 31.8 torr = 360.2 torr

Answers:
1. a flowerpot sitting on a table
2. a leaf falling to the ground
3. The object's motion does NOT change.
4. change speed, direction, or both.
5. True
Explanations:
1. Net force is the sum of the forces acting upon an object. Often, this will be shown through diagrams with arrows pointing in certain directions and a certain amount of Newtons. A net force of zero means that the object is steady and stable in its motion (whether moving or staying still). With zero net force, an object will not change its speed nor direction. A football in the air is not the answer as gravity pulls it back down towards Earth, creating a change in both speed and direction. A cat running after a mouse is likely not the answer as well. Realistically, the cat and mouse will not continue at a constant speed in the exact same direction forever. Thus, a cat running after a mouse does not make sense. A flowerpot sitting on a table is not moving at all. It is not changing speed or direction; therefore, it does have a net force of zero. A speeding car is, well, speeding. Its speed is changing, just as the answer claims. Since a flowerpot sitting on a table is the only answer choice that has a net force of zero, it is the answer.
2. Unbalanced forces are unequal forces acting on one another from/in different directions. Unbalanced forces must be moving in some way. If they are not, then the forces are equal and balanced instead. They have to be changing direction and/or changing speed. A sweater sitting on a store shelf does not move at all; it never changes direction nor speed. It is an example of balanced, not unbalanced, forces. A letter sitting in a mailbox is just like the sweater - it doesn't change speed or direction, so it can't be an unbalanced force. A fence around a garden is planted firmly into the ground, thus unable to move in the first place. With no change, it is a balanced force, rather than an unbalanced one. A leaf falling to the ground is, according to the wording of the answer choice, currently falling. Gravity is acting upon it and pulling it towards the ground. Since the leaf falling is in motion, or moving, there are unbalanced forces acting on it (specifically gravity pulling the leaf down). Therefore, the falling leaf is an instance of unbalanced forces.
3. Balanced forces are the opposite of unbalanced ones - they are equivalent forces that act in opposite directions in order to contradict/cancel each other. Since balanced forces are, well, balanced, neither one will overpower the other. No chance will occur as long as the forces remain balanced (ones). This lines up directly with Isaac Newton's first law of motion, which states that an object will continue to be at rest, or continue in a constant speed and direction, unless acting on by an external force. The external force will unbalance the forces, thus causing a change in speed and/or direction. Therefore, since balanced forces are forces that will not change speed nor direction, the answer should be that the object's motion does not change.
4. As stated earlier, unbalanced forces act in different directions with different amounts of power/Newtons. One must be/is more powerful than than rest; this is so that the unbalanced forces can be, you know, unbalanced. Unbalanced forces can cause a change in speed and a change in direction (it can be both or only one). Thanks to this information, we can conclude that the answer to this question is to change speed, direction, or both.
5. Balanced forces and a net force of zero are both included in the first law of motion. Both of these forces will continue at a consistent speed and direction until acted upon by another force. Since both of these terms have the same definition, it is reasonable to say that they are synonyms (which they are). Balanced forces and zero net force mean the same thing (and are the same thing). So, it is true that balanced forces is when the net force is zero.
The object has a net force of zero acting on it is a flowerpot sitting on a table. A leaf falling to the ground has unbalanced forces acting on it.The object's motion does not change when the forces acting on it are balanced.When unbalanced forces act on an object that is in motion, the object can change speed, direction, or both.The statement a balanced forces is one in which the net force is zero is true.
What is a force?Force is defined as a cause which is capable of changing the motion of an object. It can cause an object which has mass to change it's velocity. It is also simply a push or a pull . It has both magnitude as well as direction.Hence, it is a vector quantity.
It has SI units of Newton and is represented by'F'.Newton's second law states that force which acts on an object is equal to momentum which changes with time. If mass of object is constant, acceleration is directly proportional to net force acting on an object.
The concepts which related to force are thrust and torque .Thrust increases the velocity of an object and torque produces change in rotational speed of an object.
