Answer:
Cytosine- 40%
Explanation:
DNA is the genetic material in virtually all living organisms. It is a molecule made up of long chains of nucleotides, which are its building block. Four types of nucleotides make up the DNA molecule viz: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C).
According to Erwin Chargaff in his rule regarding DNA composition, he stated that in a DNA molecule, the amount of adenine must equal thymine while that of guanine must equal cytosine. In a nutshell, the total of all the base pair must equally be 100% i.e. (A + T) + (G + C) = 100%.
In this case where a newly discovered bacteria from a hot spring in Yellowstone National Park was found to contain 10% of adenine in its DNA. Since Adenine is 10%, Thymine base must also be 10% in accordance to Chargaff's rule.
Hence, 10% + 10% + (G + C) = 100%.
20% + G + C = 100%
G + C = 100 - 20
G + C = 80%
Since, G and C must be equal, then G = C = 80% ÷ 2 = 40%. This means that the percentage of cytosine will be 40%.
<em>Answer:</em>
Thrust and Lift.
<em>Method:</em>
There are 4 forces acting upon a plane while it is moving. Drag (The air friction while it's in the air), Lift (Generated by the wings (The upward force), Weight (How heavy the plane is), and finally, Thrust (Generated by the engines which moves the plane/wings through the air generating lift). If there is enough air going over the wing at a high enough speed, and Thrust, and Lift overcome the other two forces keeping the plane on the ground, it can fly. The air pressure under the wing is higher than over the wing - If you have ever ran you hand under the water keeping it flat, you may notice it going up, those are basically the same forces, but under water.
How does the pressure under the wing affect the lift?
The difference of air pressure over the wing (which is less), which also means less force bringing the plane down. The air pressure under the wing is higher, putting pressure on the wing moving it up. A wing is designed to make the air travel a longer distance over the wing than under the wing creating the air pressure. The engines just enforce that process.
Answer:
Produce and transport haploid gametes.
Explanation:
The reproductive system is a set of organs used to produce gametes and lead them outside the organism. Thus, this system is responsible for the production of gametes in the body of the animal or human, and in the case of male beings, their transfer to the body of the female in order to fertilize it and give way to reproduction, which is, in short, part of the tasks that every living being instinctively develops at some point in their life. The organs of the reproductive system are distinguished internally and externally. In humans, the external organ is the vagina for women and the penis for men, respectively.
Answer: In people with type AB blood, both A and B proteins are expressed on the surface of red blood cells equally.
