In 1918, an influenza pandemic that originated with avian flu killed 50 million people. researchers isolated samples of that virus from bodies of infected people preserved in alaskan permafrost since 1918. from the samples, they sequenced the viral genome, then reconstructed the virus. the reconstructed virus is 39,000 times more infectious than modern influenza strains, and 100 percent lethal in mice. understanding how this virus works can us defend ourselves against other strains that may arise. for example, discovering what makes it so infectious and deadly would us design more effective vaccines. critics of the research are concerned: if the virus escapes the containment facilities (even though it has not done so yet), it might cause another pandemic. worse, the published dna sequence and methods to make the virus could be used for criminal purposes. do you think this research makes us more or less safe?

Personally, I believe the information helps.

Explanation:

Without this information the virus would not be contained, we would not have done research, taken samples, tested out the virus, or even attempted to contain it. With this information we can attempt to prevent a break out of the disease again. This is my personal opinion though.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
