Answer:

See answer below

Explanation:

Hi there,

Assuming this DNA strand is fully capable of being mature mRNA (5' m7G cap and PolyA tail), nucleotides lead to an mRNA codon, which is 3 nucleotides per codon. In turn, 1 codon leads to 1 amino acid. However, as a single strand, it must be capable of terminating translation, which always requires a stop codon, and thus 3 nucleotides. Hence, we must subtract this from the total amount of codons first.

Hence, only 11 amino acids will be coded by a single DNA strand 36 ncltd long.

thanks,

Air pollution is caused the burning of fossil fuels, resulting in the formation of smog and acid rain.

<h3>What is air pollution?</h3>

Air pollution is the release of harmful substances into the air which makes it unfit and unhealthy for breathing.

Substance which pollute the air are known as air pollutants.

The burning of fossil fuels causes dangerous gases to enter the atmosphere. Heavy, dense fog caused by dangerous gases mixing in the atmosphere is called smog. Acid rain occurs when dangerous gases mix in the atmosphere and fall back to the surface in liquid form.

Therefore, air pollution is caused by releasing pollutants air.

1)In your own words explain what air pollution is

Anna11 [10]

Explanation:

Question 1

Air pollution is the introduction of harmful gases and substances into the atmosphere that renders it unfit for use for life. Some of these toxic gases and particulates are:

Carbon monoxide
Carbon dioxide
Nitrogen oxides
Smoke
Dust particles
Soot

Question 2

Natural forms are the original nature or outlook of a substance. Examples of natural forms are:

Flowers
Leaves
Animals
Rocks
Shells
Corals

Question 3

Anthropogenic cause of pollution are human causes of pollution. Some of these are:

Combustion of fossil fuels in internal combustion engines release harmful and toxic gases into the atmosphere and causes hair pollution.
Improper disposal of waste can produce effluent that reaches the ground water system and other fresh water sources.
Noise pollution from airports is very harmful to ear.
Mining activities degrades soil and removes rich fertile soils that should be used for agriculture.
Mining wastes can lead to contamination of water bodies around.

Question 4

Fossil fuels are fuel types that forms from natural process in which organisms are decomposed anaerobically to preserve their energy components. Some of these fuels are:

Coal
Crude oil
Natural gas

Question 5

Heart diseases ; ischaemic heart diseases can lead to failure of the heart when it does not receive enough oxygen from the environment. Air pollution contaminates available oxygen in the atmosphere and this is very dangerous to life.
Lung cancer: poor air quality can lead to the development of cancerous tumor in the lungs.
Asthma: air pollution is one of the leading cause of asthma.

Other notable mentions are bronchitis, pulmonary diseases, stroke

Question 6

_7 million____ people die each year from air pollution according to the world health organization

Question 7

Air Quality Index(AQI) is an indicator used to express the quality of air in particular area. The AQI can tell the present air quality condition. It can also be used to forecast future air quality in years to come.

It shows how clean and polluted the air is.

Question 8

The air quality index uses different colors to alert people about the quality of air. Each color represents different health implication of air quality:

Attached image shows the different colors used to alert people of about the air quality.

Question 9

About 7 million people die annually as a result of air pollution
Beijing cough is new disease that emanates from the rising air pollution in Beijing
Asia has the fastest rising cases of air pollution problems.
The best way to reduce air pollution is by riding bicycles and walking more.

The wild-type color of horned beetles is black, although other colors are known. A black horned beetle from a pure-breeding stra

Kisachek [45]

One hypothesis that explains the result is : A) Two genes are involved with 12:3:1 epistasis, such that A_B_ and A_bb are black, aaB_ is brown,and aabb is green.

Explanation:

This is a case of Dominant Epistasis.
When two genes are involved and presence of dominant allele of one gene masks the effect of either allele of the second gene then the epistasis is termed as dominant epistasis.
In the given case black :brown: green ratio is approximately equal to 12:3:1.
Here presence of a dominant A allele that is responsible for the black colour masks the effect of either allele of B. Therefore A_B_ and A_bb produces black beetles
Again , absence of dominant A allows B to express itself and Brown beetles are produced thus aaB_ is brown.
When both the genes are present as recessive alleles, neither brown nor black colour is expressed and the beetles are green.Thus, aabb are green.
