Lockdown may not be the ultimate solution for covid-19 outbreak. But however, it is one of the many ways in which the situation can be brought under control, an attempt can be made.

The
covid-19 disease is contagious. Th same disease comes up with different mutations
every few months, lately. Currently, the research says that, the latest
mutation of this disease in the 2^nd phase is spread in the air. In
other words, the disease in now in the air. The best way to avoid this to delay
direct exposure to air. Lockdown in a way helps, as it helps avoiding direct
contact with beings and also deducts direct exposure with fresh air, which is
no longer fresh. Not entirely, but the lockdown does helps in way to reduce the
commotion.

The principles of thermodynamics show that large collections of particles, like the trillions upon trillions of liquid molecules in a coffee cup, always move toward more disorganized arrangements. For instance, hot water molecules clumped together in a cold room need a lot of organization, so warm drinks eventually cool to the surrounding temperature. Physicists say such disorganized arrangements have high entropy, whereas ordered arrangements have low entropy.

Yet the equations physicists use to describe the simultaneous motions of large numbers of particles are equally valid whether time runs forward or backward. Therefore, almost any complex arrangement of matter will gain entropy no matter which direction time flows.

This is a very different question.The nomological notion of our human nature takes a different perspective. It accepts the individual differences and speaks of a human nature that is shared by most humans as a result of evolution. These properties that we share are not definitional; they are not necessarily shared by all humans. The capacity to speak, for example, could be limited in an individual due to damaged brain function. Including the evolutionary notion allows us to define a distinctive human nature. A robot could for example possess all the properties of a human being, but that does not make it human. This definition of our human nature also accepts that it is not permanent. With continuous evolution, our human nature might change over time.

The blood plays a very important and crucial in human body. It is a source through which essentials like vitamins, nutrients and oxygen travel from one place to another inside the body. Like the blood carries such important things from one place to another, it also carries impure and waste products from one place to another. Hence it is very important for blood to get purified, as if it is not purified, the impurities present in it can cause adverse effect to the body in all.

In our human body, the waste products are collected and pushed out from our body through kidney, lungs and liver. These are important organs of our body as they just not collect the waste products, but also help release pure blood in our body. In reality, kidney, liver help in detoxifying the impure blood.

Liver plays a very vital role in cleansing of the blood. The liver in a healthy human body, not only helps by collecting waste and realizing cleansed blood, but also filters unwanted byproducts. Meanwhile, the lungs help cleanse the blood by removing unwanted gases and releasing them through the breath. The kidneys also filter waste and by-products, which they release in the form of urine. These are just a few key organs that handle the cleansing of the blood. Other organs that also play a role include the: skin intestines, spleen, lymphatic system. All of these processes mean that the body typically takes care of blood cleansing without any outside help. In most cases, taking steps to keep these organs healthy is enough to ensure that the blood is clean.

In general, family is a group of people that stay together, relate to each other and stand for each other. Major function of a family is to take care of well being of their members and of the society. Ideally, one of the primary functions of family is to maintain production and reproduction biologically and socially. Families are broadly classified into two types-

· Nuclear family

· Joint family

Difference between nuclear and joint family is just not limited to difference in number of members, there is more to it. Here is a brief explanation to the above-mentioned types of family.

Nuclear family

Such a family, generally comprises of mother, father and their children. Nuclear families are also known as conjugal or elementary families. In this type of family, the flow of income is relatively lower as there is usually just a single earner in the house. Emotions shared between members in such household is quite straightforward and direct. There is more scope of freedom and privacy and less expenses. While there are perks to it, there are some disadvantages too. Members in such families don’t tend to socialize with distant relatives often, and all the members are quite like-minded, meaning no scope in having broad perspective, as all the members think on the same lines.

Joint family

Such a family, generally comprise of relatives such as aunts, uncles, cousins, grandparents, etc. Joint families are also known as extended families. Such families, generally earn more economically, as there are multiple earners in the house. Emotions shared between members of this household is more extended, every member has his/her special bond and closeness with other. Major advantage of joint family is consistent income, fallback place, constant and more support and moreover, the kids grow up with more learned. However there are few disadvantages like less privacy, less freedom, less space, tendency of jealousy and quarrel and also more expenses.

Animals are widely divided into two categories knowingly-unknowingly, that is- prey or predator. For example, animals like rabbit and mouse have general tendency to escape and move quickly, hence they are born preys.

Considering the wild range and variety of cats that exist, it is considered that the cats are both prey, as well as predators depending upon the situations.

Animals tend to study body language and size at first sight. Small cats are cuddly in nature while small dogs are highly temperamental. On the other hand, big dogs are perfect combination of fierce, sweet and cuddly temperament.

There are cases where dogs are scared of cats too. Its still a big theory that is yet to be proven.

Similes

Similes is a figure of speech. It involves comparison of one thing to another in order to make it more the sentence more vividly understandable. For example:

1. He is as brave as a lion.

2. She is as beautiful as a flower.

In other words, Similes are used for qualitative comparison. Some words that help identify a simile in a sentence are- like, as, so, than.

Metaphors

Metaphor is yet another type of figure of speech. It is basically a way of defining an object by categorically mentioning another object as partial comparison. For example:

1. Time is money.

2. Age is a state of mind.

3. The criminal has blood on his hand.

It is basically a method of comparing to unlike things. As seen in literature, metaphors compare different things without actually using words such as- like, as.

Comparison between Similes and Metaphors

There is a very small line of difference between similes and metaphors. As mentioned above, in short, Similes work on the principle of direct comparison between two similar objects while, Metaphors work on the principle of comparison between two objects that are pole apart.

An adverb is a word or an expression that modifies a verb, adjective, another adverb, determiner, clause, preposition, or sentence. Adverbs typically express manner, place, time, frequency, degree, level of certainty, etc., answering questions such as how?, in what way?, when?, where?, and to what extent?.

A great way to pick out an adverb from a sentence is to look for the word ending in -ly. Although that’s not universally true, it’s a good place to start. Also, given their function, these fundamental elements of the English language are usually placed right before or after the verb in the sentence.

Adverbs are intensifiers and they can even come in the form of an adverb phrases. That just means you’re looking at two or more words that act as an adverb. Let’s take some time to dive (v.) deeply (adv.) into these popular modifiers.

Here are some examples of adverbs modifying verbs:

He runs quickly.
She walks slowly.
He’s happily chattering
over there in the corner.

Adverbs can also modify adjectives or other adverbs. They provide more information about that other descriptive word. For example:

He runs very
quickly.

In this sentence, the adverb “very” is describing the adverb “quickly” (“very quickly” can be used as an adverb phrase).

An incredibly
pretty girl sat down next to me.

In this sentence, the adverb “incredibly” is describing the adjective “pretty.”

Pulmonary circulation is that part of the circulation system which carries deoxygenated blood away from the right ventricle in heart to lungs and returns oxygenated blood from left atrium and ventricle to the heart.

A separate system called; Bronchial Circulation circulates this oxygenated blood to the tissues of larger airways to the lungs.

From the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle. Blood is then pumped from the right ventricle through the pulmonary valve and into the main pulmonary artery.

Here is a brief over view of how this system works:

· Lungs

The pulmonary arteries carry deoxygenated blood to the lungs, where carbon dioxide is released and oxygen is picked up during respiration. Arteries are further divided into very fine capillaries which are extremely thin-walled. The pulmonary vein returns oxygenated blood to the left atrium of the heart.

· Veins

The oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left part of the heart, completing the pulmonary cycle. This blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. From the left ventricle, the blood passes through the aortic valve to the aorta. The blood is then distributed to the body through the systemic circulation before returning again to the pulmonary circulation.

· Arteries

From the right
ventricle, blood is pumped through
the semilunar pulmonary valve into the left and right main pulmonary
arteries (one for each lung),
which branch into smaller pulmonary arteries that spread throughout the lungs.

Salt accounts for about 3.5 percent of the world’s oceans. It is naturally produced when shallow ponds and bays dry up in the sun and the wind and large salt crystals are left behind where the salty water once was. Sea water contains many salts mixed in it. One of them is common salt, when sea water is allowed to stand in shallow pits, water gets evaporated by sunlight and slowly turns into water vapor. In a few days, the water evaporates completely leaving behind the solid salts. Common salt is then obtained from this mixture of salts by further purification.Today there are three main methods for obtaining salt:

Evaporation from sea water, Mining salt from the earth and Creating salt brines.

Salt is an example of a mature market for an abundant commodity. With a predictable market and no way to improve the product what happens is that profit margins are kept low and the market gets dominated by large suppliers.

Food salt is comparatively a small market and the price is so cheap that it would scarcely generate more than a few dollars per household per year.

Ice floats on water. This happens so because ice has lesser density than water. Scientists have proven that water has a density of 1.0gm/cubic cm while on the other hand, ice has density of 0.931gm/cubic cm.

The process where water converts into ice, gives the hydrogen bonding a scope to expand and get placed further apart. As a result, forcing it to take more space, decreasing the overall density and hence, making to float in the water.

Generally, pure water gets converted into its solid state at 0 degree Celsius, this is also known as its freezing point. In other words, the constant temperature at which water changes into ice is called as solidification or freezing point.

To convert water to ice it releases about 80 calories (or 4200 J/Kg) of heat energy and is this is known as specific latent heat of fusion of Ice. It is the amount of heat required to change ice at 0 degree into water at 0 degree centigrade without change in its temperature, here the amount of heat absorbed by ice is used in increasing the potential energy of its molecules.
