Explain how the ozone layer forms, how human activities have damaged it, and the consequences of the destruction of the ozone la
Vikki [24]

Answer:

Ozone is formed in the stratosphere naturally.

High energy solar radiation strike the oxygen atoms O2, the two atoms split apart. The freed atom collides with another oxygen atom O2 forming O3 (Ozone)

Ozone layer is destroyed when chloroflourocarbons and halons.

CFCs and halons cause chemical reactions that break down ozone molecules. Consequences ofnozone depletion are that UV radiations are not filtered and they reach the earth causing damage to eyes and skin.

Explanation:

Ozone layer is a protective layer which protects from UV damaging radiations. It is formed when oxygen atoms are broken down by photolysis and a freed oxygen atom combines with another amd form O3.

Ozone is being depleted now because chlorofluorocarbons (CFCs) and halons—gases found in aerosol spray cans and refrigerants—are released into the atmosphere they decrease the ozone's ultraviolet radiation-absorbing capacity.Ozone layer depletion causes increased UV radiation levels at the Earth's surface, which is damaging to human health. Negative effects include skin cancers, eye cataracts and immune deficiency disorders.

Scientists interested in the relationship among vision, foraging for food, and fitness studied three isolated populations of a s
Y_Kistochka [10]

a) Evolutionary fitness can be characterized as a person's commitment to the cutting edge's quality pool,which is chiefly founded on the aggregate or the genotype of the individual.This principally identifies with the conceptive achievement of an organic entity.  

It is fundamentally determined by the offspring that can endure and pass on the characteristics/traits.

b) Graph is already uploaded in the below attached document.  

c) The population 3 will have the most elevated frequency of heterozygotes,45% of the complete population.  

d) Since population 2 is as of now having a low number of heterozygotes, the occasion would totally eliminate them from the population or decreases their number

Explanation:

Frequency of animals in population 1 having both alleles 1 and 3

frequency of allele 1 =0.60

frequency of allele 3= 0.25

Frequency of both allele 1 and 3 would be allele 1 + allele 3 frequency x 100

= 0.60+0.25 X 100= 85%

Write a report on the ways to reduce carbon footprint by opting local produce
shtirl [24]

To many, the notion of talking about their carbon footprint is still a novel and in most instances bearing in mind that human beings are sociable creatures, the subject of carbon footprint is rarely brought up in conversations.

The term carbon footprint is defined as the amount of carbon (usually in tonnes) being emitted by an organization, event, product or individual directly or indirectly. Everyone’s carbon footprint is different depending on their location, habits and personal choice. Each of us contributes to the greenhouse gas emissions either by the way we travel, the food we eat, the amount of electricity we consume and many more.

There are people, organizations and even local governments who have begun talking about the carbon footprint and motivating each other to put in place plans to reduce their carbon footprint. But they aren’t always sure about the most effective ways forward.

Hundreds of companies are making their effort to reduce their own carbon footprint. Some ways to reduce carbon footprint:

Driving – Hybrids may still be out of reach of most drivers, mainly due to its price, but it is a necessary alternative to conventional vehicles run on petrol or diesel. Also, when driving, motorists should avoid heavily congested road networks. How well they drive also makes an impact on reducing their carbon footprint.

Instead of driving – The popular and healthy advice is to walk instead of driving. Those who have too far to travel can also use rapid bus transport networks and urban rail networks.

Less red meat – Vegetarians are already off to a good start because most of their consumptive waste can be recycled easily. However the greenhouse gas emissions from agricultural produce such as cattle and poultry are substantial. Where there is less demand surely emissions can be reduced.

Buy local – Adding to the above remark, buying local, organic produce effectively counters mass-produced agricultural outcomes. There is a dramatic reduction in the amount of plastic being used to package products and fuel usage during long road transits is also reduced.

Energy efficiency at home – All appliances that are not being used must be switched off immediately. And all electrical outlets not in use must also be switched off. Hot-water geysers should be switched off for the entire day and only turned on when needed. These are simple, yet practical lifestyle habits which are easy to adopt.

Buy green energy – It is quite possible to power your own home with environmentally-sustainable alternatives of energy production without compromising your lifestyle and waiting for national grids to be connected via green energy supply sources. For instance, technology is now available for you to install your own solar power panels.

Recycle and re-use – Vegetable produce can be converted into compost (or manure) for gardens, even vegetable gardens. Instead of buying more food containers, plastic containers sourced from the supermarket can be refashioned as ideal kitchen utensils. Also, where plastic waste is no longer required, seek out recycling depots rather than relying on your supplied garbage disposal units.

Plant a Tree – One of the best way to give it back to the environment is to plant trees. Plants absorb CO2 and release oxygen that is then used by humans and animals. According to the Urban Forestry Network, a single young tree absorbs 13 pounds of carbon dioxide each year.
