The correct answer is class mammalia and the subclass Cetacea.

Explanation:

• WHALES and walruses are the aquatic mammals that are marine in nature.
• They have all the aquatic characteristics but they are vertebrates and they have LUNGS to respire, as well as they FEED their YOUNG ones with their milk.
• They also perform SEXUAL reproduction just like mammals.
• They belong to the subclass Cetacea with dolphins. So they are in class mammalia.

Cropping PATTERN:
In order to get maximum BENEFITS from the piece of land, different pattern of growing crops are followed. These are:
Mixed cropping
Intercropping
Crop rotation

1. Mixed cropping:
The practice of cultivating two or more crops simultaneously on the same piece of land is CALLED mixed cropping. During mixed cropping, if ONE crop faces adverse conditions or pathogen attack then the other crop can be saved.

2. Intercropping:
The practice of growing two or more crops simultaneously in a same field in definite row pattern is called intercropping.

3. Crop rotation:
The practice of growing different crops on the same piece of land in a preplanned succession is called crop rotation.

The some examples of growth irrelevant movement are:-

1. Closing of leaflets of mimosa plant when touched.

2. Opening of lotus in the morning and TUBEROSE at night.

3. Insectivorous PLANTS like drosera curl INWARDS at the touch of an insect and TRAP the insect.

4. The explosive fruit of balsam plant bursts open at an appropriate time thus scattering the seeds.

Well..........There are two types of cells that you can observe : -  

1)RBC - Red Blood Cell.It has a PIGMENT called hemoglobin which carries OXYGEN to all parts of the BODY.  

2)WBC - White Blood Cell.It fights against the diseases carrying foreigner cells or viruses that enters our body.

There are many different varieties of silk found around the world among them most common are mulberry silk,eri silk and MUGA silk.

The mulberry silk is most common. About 90% of silk are of this variety. This variety is produced by bombyx mori (DOMESTIC moth larva). The larva feeds on mulberry plants thats why the silk produced by them is CALLED mulberry silk.

Decomposers are the organismswhich convert dead and decaying matter into organic matter of the soil. They break down the COMPLEX organic compounds PRESENT in dead ANIMALS and plants, which are then used by other members of the ecosystem. *Decomposers like bacteria and fungiare known as saprobes.

Movement of air is caused by TEMPERATURE or pressuredifferences and is eperienced as wind. Where there are differences of pressure between two places, a pressure gradient exists, across which air moves: from the high-pressure region to the low-pressure region. This movement of air however, does not follow the quickest straight-line path. In fact, the air moving from high to low pressure follows a spiralling route, outwards from high pressure and inwards towards low pressure. This is due to the rotation of the Earth beneath the moving air, which causes an apparent deflection of the wind to the right in the Northern Hemisphere, and to the left in the Southern Hemisphere. The deflection of air is caused by the Coriolis force. Consequently, air blows anticlockwise around a low-pressure centre (depression) and clockwise around a high-pressure centre (ANTICYCLONE) in the Northern Hemisphere. This situation is reversed in the Southern Hemisphere.

Wind caused by differences in temperature is known as convection or advection. In the atmosphere, convection and advection transfer heat energy from warmer regions to colder regions, either at the Earth surface or higher up in the atmosphere. Small-scale air movement of this nature is observed during the formation of sea and land breezes, due to temperature differences between seawater and land. At a much larger scale, temperature differences across the Earth generate the development of the major wind belts. Such wind belts, to some degree, define the climate zones of the world.

Air temperature is generally higher at ground level due to heating by the Sun, and decreases with increasing ALTITUDE. This vertical temperature difference CREATES a significant UPLIFT of air, since warmer air nearer the surface is lighter than colder air above it. This vertical uplift of air can generate clouds and rain. Sometimes air from warmer regions of the world collides with air from colder regions. This air mass convergence occurs in the mid-latitudes, where the warm air is forced to rise above the colder air, generating fronts and depressions.

ANSWER:

I HOPE it HELP you.......

Since the RESISTANCE is more, current WOULD not flow easily. A thick wire would have LARGE AREA of cross section, hence less resistance. Since the resistance is less, current would flow easily. Hence, current would flow more easily in a thick wire

The current will flow more easily through the thick wire than the thin wire. It is because the resistance of a conductor is inversely proportional to its area of cross-section. If thicker the wire, less is resistance and hence more easily the current flows.

⇝Immunization is the process whereby a person is made immune or resistant to an infectious disease, typically by the ADMINISTRATION of a vaccine. Vaccines stimulate the body’s own immune system to protect the person against subsequent INFECTION or disease.

This happens because when the immune system first sees an infectious microbe, it responds against it and then remembers it specifically. So the next time that particular microbe, or its close RELATIVES enter the body, the immune system responds with even greater vigor. This eliminates the infection even more QUICKLY than the first time AROUND. This is the basis of the principle of immunisation.

Answer:

Air pollution is the presence of substances in the atmosphere that are harmful to the health of humans and other living beings, or cause damage to the climate or to materials. There are different types of air pollutants, such as gases (such as ammonia, carbon monoxide, sulfur dioxide, nitrous oxides, methane and chlorofluorocarbons), particulates (both organic and inorganic), and biological molecules. Air pollution may cause diseases, allergies and even death to humans; it may also cause harm to other living ORGANISMS such as animals and food crops, and may damage the natural or built environment. Both human activity and natural processes can generate air pollution.

Air pollution is a significant risk factor for a number of pollution-related diseases, including respiratory infections, heart disease, COPD, stroke and lung cancer. The human health effects of poor air quality are far reaching, but principally affect the body's respiratory system and the cardiovascular system. Individual reactions to air pollutants depend on the type of pollutant a person is exposed to, the degree of exposure, and the individual's health status and genetics.Indoor air pollution and poor urban air quality are listed as two of the world's WORST toxic pollution problems in the 2008 Blacksmith Institute World's Worst Polluted Places report.Outdoor air pollution alone causes 2.1]to 4.21 million deaths annually.Overall, air pollution causes the deaths of around 7 million people worldwide each year, and is the world's largest single environmental health risk.

VARIOUS pollution control technologies and strategies are available to reduce air pollution.
