Ozone is produced naturally in the stratosphere. But  "good" ozone is  referred to as ozone-depleting substances (ODS), including chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, methyl bromide, carbon tetrachloride, and methyl chloroform. These were are sometimes still used in coolants, foaming agents, fire extinguishers, solvents, pesticides, and aerosol propellants. Once released into the air these ozone-depleting substances degrade really slowly. They can remain intact for years as they move through the troposphere until they reach the stratosphere.

explain how a difference in the sequence of nucleotides in a gene could result in one of these boys being albino and the other b
Zolol [24]
Albinism is a recessive trait characterized by an absence of pigment melanin responsible for skin and hair color. Actually, albinism is caused by a defect in gene for enzyme which synthesizes melanin. The central dogma of molecular biology explains that the sequence of DNA specifies the sequence of mRNA, which, further, specifies codes for the sequence of proteins. Since a gene is a segment of DNA, altered gene will cause altered mRNA which will cause altered protein. Thus, <span>defect in gene for enzyme which synthesizes melanin will cause the absence of melanin and consequently, albinism.</span>

Which method would allow you to study the behavior of a tiger in its native habitat in India?
IgorLugansk [536]
They are solitary animals, especially males who do not live in groups, unlike the female which can form small groups of three or four members with their young.

The males are very territorial, so take care of their personal space and the females with whom they mate. To mark their territory, they spray the trees and rocks with a mixture of urine and musk.

Both male and female, they are related only in times of mating and reproduction. There have been cases where the male is responsible for feeding breeding if the mother has died.

The gestation period lasts between 98 and 108 days and give birth to two to four cubs weighing just over a kilo. They have a short life expectancy, as only get to live 10 to 12 years in the wild, but in captivity Natural mortality manage to live up to 26. It is mainly due to the fighting between males

Thale cress is a plant that is genetically engineered with genes that break down toxic metals. Which type of organism is describ
Misha Larkins [42]

Any genetically engineered organisms is referred to as a transgenic organism.

A transgenic organism is any organism that was modified genetically or engineered by humans, for certain purposes, in this case, the function of the thale cress is to break down toxic metals in the water (cress plants grow on water).

Hope it helped,

Happy homework/ study/ exam!

how will solar energy affect us in the future? ESSAY DUE AT 9:00 A.M tomorrow. Please finish I will give 100 points

Answer:

i love you:)

Explanation:

Solar energy has come a long way in a decade. Back in 2010, the global market was small and highly dependent on subsidy regimes in countries such as Germany and Italy. This year there will be more than 115 gigawatts (GW) of solar installed across the world, which is more than all other generation technologies put together. It is also increasingly low cost, especially in sunnier regions where it has already become the lowest-cost form of new electricity generation.

In the coming years, technology improvements will ensure that solar becomes even cheaper. It could well be that by 2030, solar will have become the most important source of energy for electricity production in a large part of the world. This will also have a positive impact on the environment and climate change.

Going forward the solar industry has very clear cost-reduction roadmaps, which should see solar costs halving by 2030. There is already a move in place towards higher-efficiency modules, which can generate 1.5 times more power than existing, similarly sized modules today using a technology called tandem silicon cells. These are going to have a large impact going forward.

In addition, there are production innovations coming down the pipeline that will reduce the amounts of costly materials such as silver and silicon used in the manufacture of solar cells, as well as innovations such as bifacial modules which allow panels to capture solar energy from both sides. The other important innovation is around how best to integrate solar into our homes, businesses and power systems. This means better power electronics and a greater use of low-cost digital technologies.

What this means is that solar will reach, in many parts of the world, a levelized cost of energy that will make it unbeatable compared to fossil fuels. Given that solar is so easy and quick to install, not to mention flexible - after all, solar can be used to power something as small as a watch or as large as a city - it should mean that solar installations continue to grow over the coming decade. This could also be very good for the climate. Now that is something bright to write about.
