Match the following terms and definitions. 1. alternative form for a specific gene (either dominant or recessive) hybrid 2. can

galben [10]

The answers would be:

1. Allele - alternative form for a specific gene (either dominant or recessive)

2. Dominant - can prevent the allele from being expressed in a pair of genes

3. Genotype - the genes present in an organism

4. Heterozygous - it is a pair of non-identical genes that influence a trait in different ways.

5. Homozygous - a pair of genes that are identical in the way they influence a trait.

6. Hybrid - offspring from a cross between parents; has different phenotypes for a specific trait.

Here's a little bit more on the topic to help you out in the future:

Alleles are variant forms of genes. Each allele is found in a specific location of a chromosome and that location determines the trait that will be expressed.

There are two types of alleles: Dominant alleles and Recessive alleles.

A dominant allele is expressed physically while a recessive allele is the trait that is masked. If both alleles are present, the dominant allele usually masks the recessive allele. This phenomenon is called complete dominance. There are some traits where both alleles are equally expressed, which is called co-dominance.

Genotype is the set of genes present in an organism that is responsible for specific traits. Phenotype on the other hand is the physical expression of the trait, which depends on the genotype of the organism.

Alleles come in pairs, they could either be homozygous or heterozygous.

Homozygous pairs consist of either 2 dominant alleles or 2 recessive alleles. The genotype would look something like this:

2 dominant :RR or 2 recessive: rr

Heterozygous pairs consist of non-identical alleles, or it has one dominant and one recessive allele. So the genotype would look like this:

Rr

Finally, hybrid is the cross-breeding of two different species that are genetically different. There are many examples of hybrid species like the liger and the mule. The resulting off springs express traits that are different than both parents.

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.

How are DNA replication and DNA cloning similar? How are they different?
