Answer 2

What are the states of energy? List the Laws of Thermodynamics.
Answer: The first law, also known as Law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system. The second law of thermodynamics states that the entropy of any isolated system always increases.

Paragraph: Discuss the three laws of thermodynamics.
Key Points

The first law, also known as Law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system.
The second law of thermodynamics states that the entropy of any isolated system always increases.
The third law of thermodynamics states that the entropy of a system approaches a constant value as the temperature approaches absolute zero.
Terms

absolute zeroThe lowest temperature that is theoretically possible.
entropyA thermodynamic property that is the measure of a system’s thermal energy per unit of temperature that is unavailable for doing useful work.

System or Surroundings

In order to avoid confusion, scientists discuss thermodynamic values in reference to a system and its surroundings. Everything that is not a part of the system constitutes its surroundings. The system and surroundings are separated by a boundary. For example, if the system is one mole of a gas in a container, then the boundary is simply the inner wall of the container itself. Everything outside of the boundary is considered the surroundings, which would include the container itself.

The boundary must be clearly defined, so one can clearly say whether a given part of the world is in the system or in the surroundings. If matter is not able to pass across the boundary, then the system is said to be closed; otherwise, it is open. A closed system may still exchange energy with the surroundings unless the system is an isolated one, in which case neither matter nor energy can pass across the boundary.

The First Law of Thermodynamics

The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. For example, turning on a light would seem to produce energy; however, it is electrical energy that is converted.

A way of expressing the first law of thermodynamics is that any change in the internal energy (∆E) of a system is given by the sum of the heat (q) that flows across its boundaries and the work (w) done on the system by the surroundings:

Δ
E
=
q
+
w
Δ
E
=
q
+
w

This law says that there are two kinds of processes, heat and work, that can lead to a change in the internal energy of a system. Since both heat and work can be measured and quantified, this is the same as saying that any change in the energy of a system must result in a corresponding change in the energy of the surroundings outside the system. In other words, energy cannot be created or destroyed. If heat flows into a system or the surroundings do work on it, the internal energy increases and the sign of q and w are positive. Conversely, heat flow out of the system or work done by the system (on the surroundings) will be at the expense of the internal energy, and q and w will therefore be negative.

The Second Law of Thermodynamics

The second law of thermodynamics says that the entropy of any isolated system always increases. Isolated systems spontaneously evolve towards thermal equilibrium—the state of maximum entropy of the system. More simply put: the entropy of the universe (the ultimate isolated system) only increases and never decreases.

A simple way to think of the second law of thermodynamics is that a room, if not cleaned and tidied, will invariably become more messy and disorderly with time – regardless of how careful one is to keep it clean. When the room is cleaned, its entropy decreases, but the effort to clean it has resulted in an increase in entropy outside the room that exceeds the entropy lost.

The Third Law of Thermodynamics

The third law of thermodynamics states that the entropy of a system approaches a constant value as the temperature approaches absolute zero. The entropy of a system at absolute zero is typically zero, and in all cases is determined only by the number of different ground states it has. Specifically, the entropy of a pure crystalline substance (perfect order) at absolute zero temperature is zero. This statement holds true if the perfect crystal has only one state with minimum energy.

What is the name given to the process by which a parent cell becomes two identical daughter cells?(1 point)

A. meiosis
B. differentiation
C. senescence
D. mitosis

Answers

Answer:

D. mitosis

Explanation:

Mitosis is the process whereby the parent cell divides into two daughter cells that are identical.

Mitosis is the process by which a parent cell becomes two identical daughter cells. So, the correct option is (D)

What is mitosis ?

Mitosis is the process in which cell duplication, or reproduction takes place. Wherein one parent cell gives rise to two genetically identical daughter cells. Mitosis is the duplication and distribution of chromosomes which carries the genetic information.

It is an important process in single celled eukaryotes as it is the mode of asexual reproduction. The main function of Mitosis is to produce more cells.

Life starts with single cell in multicellular organism which is formed from two gametes. Mitosis takes place one cell is divided into two cells as this single celled multicellular organism only carries genetic information in the form of DNA but not enough cells. These two cells further divide mitotically into four cells, then into 8 , then 16 and then 32.

It is essential to life because it give rise to new cells for growth and replacement of dead cells. It may take few minutes or some hours, depending on the type of cells. It depends on time, temperature and chemicals.

Thus, mitosis is the process by which a parent cell becomes two identical daughter cells. So, the correct option is (D).

endocytosis

Explanation:

Endocytosis is defined as the process of trapping a particle or even a substance from the external environment by the process of engulfing it. The flexibility of the cell membrane helps the cell to engulf the food and also other materials from the external environment. Such a process is called endocytosis whereas exocytosis is the fusion of secretory vesicles with the plasma membrane and results in the discharge of vesicle content into the extracellular space
