To convert m/sec into km/hr, multiply the number by 18 and then divide it by 5.
Step 1:
Multiply 36 by 18
We have 36 * 18 = 648
Step 2:
Divide 648 by 5
648/5 = 129.6 km/he
Final Answer:
20 m/sec = 72 km/hr

In sexual reproduction, the *** cells of one parent fuses with the *** cell of the other parent to form a new cell called zygote which develops into a new organism. The production of a new organism from two parents by making use of their *** cells is called sexual reproduction. Fertilization is the first step in sexual reproduction. When sperms come in contact with an egg, one of the sperms may fuse with the egg. Such fusion of the egg and the sperm is called fertilization. During fertilization, the nuclei of the sperm and the egg fuse to form a single nucleus which results in the formation of a fertilized egg or zygote. It is due to fertilization that the new individual inherits some characteristics from the mother and some from the father.

It is difficult to make antiviral medicines than making antibiotics because viruses have few biochemical mechanisms of their own. They enter the host cells and use their machinery for their life processes. So, antiviral medicines will work against the host body. Antibiotics block bacterial synthesis pathways without affecting the body because bacteria use its own metabolic pathway machinery so, it will not affect the host body.

A homogeneous mixture is a mixture of two or more chemical substances (elements or compounds), where the different components cannot be visually distinguished. The composition of homogeneous mixtures is constant. ... Some mixtures can be separated into their components by physical (mechanical or thermal) means. If some components are magnetic, they can be separated by using electromagnets, that is, a magnetic separation. Centrifugation can also be used to separate out components. Filtering the mixture through various filter layers (or sieves) can also separate out various components.

The pressure exerted by a gas uniformly across the surface of a container can be described by simple kinetic theory. The particles of a gas are constantly moving in random directions and frequently collide with the walls of the container and/or each other. The sum of all the normal components of force exerted by the particles impacting the walls of the container divided by the area of the wall is defined to be the pressure.

Evaporation is known as the process of water changing from liquid to gas or vapour. As in it occurs on the surface of a liquid when it turns into the gaseous phase. It is an endothermic process when the heat is absorbed.

The mass per unit volume of a substance is called density (density = mass/volume). As the volume of a substance increases, its density decreases.
Liquids have lower density than that of solids. Water is also a liquid so it should also have less density than that of solid that is ice.
Though ice is a solid, but it has a cage like structure hence there are large number of empty spaces between its particles. These spaces are larger as compared to the spaces present between the particles of water. Thus for a given mass of water, volume of ice is greater than that of water. Hence, the density of ice is less than that of water. A substance with lower density than water can float on water. Therefore, ice floats on water.

If the displacement of an object is proportional to the square of the time taken then the body is moving with uniformly accelerated motion as it will follow Newton's second equation of motion for a particular initial velocity, which can be given by, s=ut+1/2at2. The direction of motion of an object at any point in space is determined by its instantaneous velocity at that point. The acceleration is a measure of the change of velocity in unit time at that point which need not be in the same direction as the direction of the motion of the object.

There are many different types, sizes, and shapes of cells in the body. For descriptive purposes, the concept of a "generalized cell" is introduced. It includes features from all cell types. A cell consists of three parts: the cell membrane, the nucleus and, between the two, the cytoplasm. Within the cytoplasm lie intricate arrangements of fine fibers and hundreds or even thousands of miniscule but distinct structures called organelles.

Multicellular organisms are made up of millions and trillions of cells. All these cells perform specific functions. All the cells specialised for performing similar functions are grouped together as tissues in the body. Hence, a particular function is carried out by a group of cells at a definite place in the body. Similarly, different functions are carried out by different groups of cells in an organism and this is known as the division of labour in multicellular organisms.

In healthy, dividing human cells, each of these chromosomes is duplicated and one copy passed to each of the two daughter cells. However, if this process is disturbed, daughter cells receive an unequal number of chromosomes, a state that is known to drive normal cells to become cancerous. If they do not align correctly, they cannot move individually to opposite poles in the later phases of mitosis, and the result will be one cell with extra chromosomes and a daughter cell with missing chromosomes. These mutations can lead to harmful results such as cell death, organic disease or cancer.

- Meiosis is the form of nuclear cell division that results in daughter cells that have one half the chromosome numbers as the original cell.
- In organisms that are diploid, the end result is cells that are haploid. Each daughter cell gets one complete set of chromosomes, i.e., one of each homologous pair of chromosomes.
- In humans, this means the chromosome number is reduced from 46 to 23.
- The only cells that undergo meiosis will become sperm or eggs.
- Mitosis is a continuum process of cell division which occurs in all types of living cells.
- Mitosis involves four basic phases – prophase, metaphase, anaphase and telophase.
- Mitosis is the process where the division of cell occurs by asexual reproduction.
- In mitosis, the nuclear membrane is broken down, spindle fibres (microtubules) attach to the chromatids at the centromere and pull apart the chromatids.

The burning of fossil fuels, in both energy plants and vehicles, releases massive amounts of carbon dioxide into the atmosphere, causing climate change. Industrial processes also emit particulate matter, such as sulfur dioxide, carbon monoxide and other noxious gases. Environmental risk factors, such as air, water and soil pollution, chemical exposures, climate change, and ultraviolet radiation contribute to more than 100 diseases and injuries.
