Answer:
what is the source of the chemical :bacteria/bacterial cells ?
why?:if a virus tries to attack the bacteria ,it uses restriction enzymes to fight it off .
.cleave foreign DNA,this eliminating infectious organisms..
EcoR1 restriction site
it is also part of the restriction modification system.In molecular biology it is used as a restriction enzyme .
why do we sometimes use multiple restriction enzymes?
..these enzymes cut both strand of the target DNA at different spots creating 3'-5' overhangs of 1 to 4 nucleotides.
to be able to clone a DNA insert into a cloning or expression vector ,both have to be treated with two restriction enzymes that create compatible ends.
what is the role of each of these chemicals in copying DNA?
primer
:is a short nucleic acid sequence that provides a starting point for DNA synthesis .this synthesis of a primer is necessary because the enzymes that synthesize DNA ,which are called DNA poly merases ,can only attack new DNA nucleotides to an existing strand of nucleotides .
tag polymerase:
Due to its key role in synthesizing and amplifying new strands of DNA ,Tag DNA Polymerase is essential to poly chain reaction PCR.
like other DNA polymerase can only produce DNA if it has primer,a short sequences of 20 nucloetides that provide a starting point for DNA synthesis.
nucleotides:
DNA is made up of a double helix of two complementary strands ,during replication ,these strands are separated .most prominently,DNA polymerase sythesizes the new strands by adding nucleotides that complement each strand .
DNA replication occurs during the S-Stage of interphase.
methods the separate pieces of DNA
.Gel electrophoresis is a technigue used to separate DNA fragments according to the size .
what pulls the pieces of DNA ?
DNA samples are loaded into wells at one end of a gel ,and an electric current is applied to pull them through gel.
why?
because all DNA fragments have the same amount of change per mass ,small fragments move through the gel.

C. oxygen exist as a gas in your lungs carbon dioxide exists as a liquid
D.Carbon dioxide exist as a gas in your lungs oxygen exists as a liquid
Answer:
A. Your body needs oxygen to function carbon dioxide is a waste gas
During respiration, person takes in oxygen and removes out carbon dioxide. Person's body needs oxygen to function carbon dioxide is a waste gas.
What is respiration?Respiration is the process of taking in oxygen, using it for releasing energy and throwing out carbon dioxide. It can be aerobic or anaerobic.
Respiration involves following steps:
Taking in oxygen through nostrils for various functions.Exchange of gases from alveoli to blood.Transport of gases with the help of blood vessels.Exchange of gases between body cells and blood.Cellular respiration.The carbon dioxide is then released to the environment as waste.
Thus, the correct option is A.

The aorta is a major artery, rising upward from the left ventricle of the heart and curving down to carry blood to the abdomen and lower half of the body. The curved artery can be approximated as a semicircular arch whose diameter is 6.1 cm. If blood flows through the aortic arch at a speed of 0.27 m/s, what is the magnitude (in m/s2) of the blood's centripetal acceleration?
Answer:
2.39m/s2
Explanation:
To get the magnitude of the blood's centripetal acceleration in the aortic arch, we use
a = (V^2) / d
where: a = aortic arch's blood's centripetal acceleration
V = the speed of the blood
d = diameter of the aorta
Since it is semicircular of the arch, so we use the radius
So, r = d / 2
V = 0.27 m/s
r = 6.1 cm / 2 = 3.05 cm
convert cm to m (100cm = 1m)
3.05cm / 100cm = 0.0305 m
a = (0.27 m/s)^2 / 0.0305 m
= 0.0729m/s / 0.0305 m
= 2.39m/s2

B.
It directly causes acid rain.
C.
It is the main component of smog.
Answer:
Hey!
Your answer is C. It is the main component of Smog
Explanation:
Its C because Smog is LOW LEVEL OZONE mixed up with particulate matter (pollution in other words), That's what gives it its distinct smell...it also contains Sulphur Dioxide, Nitrogen Oxides and Carbon Monoxide.
I HOPE THIS HELPED YOU! :D
The ozone layer is the main component of smog.
The ozone layer is a part of the atmosphere that protects the earth from the rays of the sun. The energy emitted from the sun is very high and therefore it is important for the earth to be protected from the rays so all living things on earth would not get hurt in any way. The ozone layer absorbs the ultra radiation that comes from the sun.
The ultra radiation from the sun is capable of destroying the DNA strands, this can cause cancer in the human body. It can also cause a lot of skin problems. The ozone layer acts as a shield that protects the earth. The ozone layer which is present and can be found at the ground level is a dangerous air pollutant that is harmful to the body, this is because its main component is SMOG. SMOG is a type of air pollutant that causes poor visibility.
