1. Cell starts into mitosis phase of the cell cycle.
2. Helicase begins to break the hydrogen bonds between the nitrogen bases. (The double helix has to be unwound in order to expose the nucleotides)
3. DNA polymerase attach the free-floating nucleotides to the exposed nitrogen bases. (this allows a new DNA strand to be made on the existing one)
4. Free floating nucleotides pair up with exposed nitrogen bases (this is what really builds the new strand, based around the template strand)
5. Two new molecules of DNA are created
Statements:
Adenine
Cytosine (Car in the Garage, Apple in a Tree is a good trick to know how they pair)
DNA
Replication
Double helix
Answer:
Explanation:
Organisms were first classified more than 2000 years ago by the Greek philosopher, Aristotle. 1. Aristotle first sorted organisms into two groups – plants and animals.
is the 292nd anniversary of the birth of Carolus Linnaeus, the Swedish botanical taxonomist who was the first person to formulate and adhere to a uniform system for defining and naming the world's plants and animals
Which of these values would most likely be the heritability of body mass index (BMI) in a developing country with a large gap between nutrition and health care available to the rich and poor?
a. 0.33
b. -0.88
c. 0.99
d. 0.0001
e. 1.3
Answer:
a. 0.33
Explanation:
Body Mass Index is defined as the measure of fat depending on the height and weight of individuals. It is being calculated as: BMI=
The most likely heritability of body mass index(BMI) in a developing country with a large gap between nutrition and health care will be 0.33.
These is because in developing countries especially countries experiencing rapid economic growth as illustrated by the annual GDP growth rate are likely to have widely ranging lifestyles due to influences of the burgeoning economy, Therefore, there are greater chances for the rich to have access to the basic requirements and necessities of life whereas the poor are limited with either low or no access to adequate nutrition and health care.
Pt.I
All living things needs some form of oxygen to live. In talking about a scuba diver, we are talking about a human, who uses their lungs to breathe, and did not develop the ability to breathe under water. Instead, when in a body of water, we tend to hold our breaths until an opportunity arises for us to exchange our carbon dioxide for oxygen.
Take into account the scuba gear. The scuba gear fits the user, and has a number of protection, including the suit counter-balancing any pressure applied by the deep, and the tank providing much needed oxygen to the user during delayed periods within the water.
Pt.II
<u>How does these two systems interact?</u>
Like as a human is breathing on land or even swimming, the human expels carbon dioxide, which forms into "air bubbles" that are then expelled into the water surrounding. The user then draws air from the pressurized air tank, and is able to breathe as such. This allows the user to stay underwater for much longer than just one breathe, and is able to travel farther inside the deep.
Inside this system, the Oxygen is first input into the oxygen tanks, which are then used by the diver. The diver would draw the oxygen from the tank (output), and he will then expel the used air into the surrounding water.
