1 kilometer is equal to 1000 meters.
1 Hour is equal to 60 minutes.
1 minute is equal to 60 seconds.
Hence 1 hour is equal to 60*60 =36000 seconds
To convert 54 km/h into m/s
= 54 * 1000 /60 *60
=54000/3600 =540/36
=15 m/s
Hence, 54 km/h is equal to 15 m/s.

Plasma membrane called a selectively permeable membrane because it regulates the movement of substances from within to outside of the cell. This means that the plasma membrane allows the entry of some substances while preventing the movement of some other substance.

Newton’s first law states that "a body remains in the state of rest or uniform motion in a straight line unless and until an external force acts on it."

Answer:
(i) For uniform motion of an object, its distance-time graph is a straight line with constant slope. (ii) For non-uniform motion of an object, its distance-time graph is a curved line with increasing or decreasing slope.

There are three equations of motion for bodies travelling with uniform acceleration. These are explained below:
1. First Equation of Motion:
(Velocity-Time Relation)
v = u +at
Where, v = Final velocity of body
u = Initial velocity of body
a = Acceleration
And t = Time
2. Second Equation of Motion:
(Position-Time Relation)
3. Third Equation of Motion:

- Newton's First Law of Motion: Any object remains in the state of rest or in uniform motion along a straight line, until it is compelled to change the state by applying external force.
- Newton's Second Law of Motion: The rate of change of momentum is directly proportional to the force applied in the direction of force.
- Newton's Third Law of Motion: There is an equal and opposite reaction for evrey action

| Mitosis | Meiosis |
| 1) This division takes place in somatic cells and as a result of this division growth occurs. | 1) This takes place usually in reproductive cells and as a result of this character one generation pass into the other. |
| 2) Completed in one stage. | 2) Completed in two stages. |
| 3) Prophase is smaller (as compared to prophase of Meiosis). | 3) Prophase longer than prophase of mitosis and divided into five substages. |
| 4) No crossing over takes place. | 4) Crossing over takes place in which exchange of segments of chromatids occurs. |
| 5) Synapsis does not take place at metaphase. | 5) Synapsis between homologous chromosomes takes place (bivalent stage). |
| 6) At metaphase, centromere is towards equatorial plate and ends of chromosomes towards poles. Centromere divides. | 6) At metaphase I, the centromere is towards poles and ends of chromosomes towards equatorial plate. Centromere does not divide. |
| 7) Chromatids are long and thin. | 7) Chromatids are shorter and thick |
| 8) Cytokinesis follows karyokinesis. | 8) After Telophase I, cytokinesis does not takes place always (may occur). |

576 Megapixels
The Resolution Of The Human Eye Is 576 Megapixels. The average human retina has five million cone receptors on it. Since the cones are responsible for colour vision, you might suppose that this equates to a five megapixel equivilant for the human eye.

The unwanted plants that grow by their own in the cultivating fields and compete with required crops for food, light, space and essential nutrients present in the soil are called weeds.
For example, Parthenium (gajar ghas), Cyperinus rotundus (motha).

The term chlor-alkali refers to the two chemicals (chlorine and an alkali) which are simultaneously produced as a result of the electrolysis of a saltwater. The most common chlor-alkali chemicals are chlorine and sodium hydroxide (caustic soda) but can include potassium hydroxide and muriatic acid. The chlor-alkali industry uses brine (salt water) to produce chlorine, sodium hydroxide (NaOH or caustic soda), and hydrogen. An electric current is passed through the brine, to form hydrogen gas at the negative electrode and chlorine gas at the positive electrode, leaving a solution of sodium hydroxide.

A matrix is a rectangular array of numbers or other mathematical objects for which operations such as addition and multiplication are defined. The extracellular matrix is made up of proteoglycans, water, minerals, and fibrous proteins. A proteoglycan is composed of a protein core surrounded by long chains of starch-like molecules called glycosaminoglycans.

Cytoplasm
- A thick solution composed of water, salts, and proteins that fills the cell is called cytoplasm.
- It is surrounded by cell membrane.
- The nucleus of the cell is surrounded by the cytoplasm
Golgi apparatus
- The stacks of flattened membranous vesicles are called Golgi apparatus.
- It basically stores, packs and modifies the products in vesicles.
- It temporarily stores protein that moves out of the cell through the vesicles of the Golgi apparatus.
- It packs and transports the materials synthesised in Endoplasmic Reticulum to different targets inside and outside the cell.
Endoplasmic reticulum
- The large network of membranous sheets and tubes is called endoplasmic reticulum.
- They are filled with fluids and carries materials throughout the cell due to which it is also called transport system of the cell.
- It transports materials between the regions of cytoplasm or between the cytoplasm and nucleus.
- It also provides a surface for some biochemical activities of cell.
- It can be classified into two types:
- RER (Rough Endoplasmic Reticulum)
- SER (Smooth Endoplasmic Reticulum)

Plasma membrane
- Plasma membrane is the outermost layer in cells.
- It separates the content of cell from their external environment.
- It allows the materials from surrounding to enter and exit the cell. It also allows the materials from cell to exit outside.
- It controls the entry and exit of materials in nd out of cell and hence it is called selectively permeable membrane.
- Gases like carbon-dioxide or oxygen can also move in or out from high concentration to low concentration in a cell through the cell membrane by the process of diffusion.
- It also allows the movement of water in and out of the cell depending upon the concentration outside the cell by the process of osmosis.
Nucleus
- The nucleus is small, round and membrane bound structure found in cell.
- The fluid inside the nucleus surrounded by nuclear membrane is called nucleoplasm.
- It controls the cell’s growth and reproduction because it contains cell's hereditary information.
- It is covered by dual layer called nuclear membrane.
- The nuclear membrane contains pores due to which materials can travel both inside the nucleus from its outer surrounding i.e. cytoplasm.
Cell wall
- Cell Wall is found in plant cells outside the plasma membrane.
- It is a rigid covering made up of cellulose which a complex substance is providing structural support to the plants.
- The contents of the cell wall contracts during loss of water in plant cells by the process of osmosis.
- Due to the presence of cell wall plant cells can withstand greater changes in the surrounding media due to the exertion of equal pressure to the cell when it swells up by taking up water through osmosis in a hypnotic media.
