the bar and provide a short explanation for your choice.

Answers

Assuming height of the bar represents altitude, the bar representing Han Chinese will be shorter compared to that representing Tibetans since Han Chinese live at lowlands.

What is the role of natural selection in evolution in Tibetanscompared to Han Chinese?

Tibetans and Han Chinese are thought to originate fro. same ancestors.

However, while the Han Chinese lived in lowland areas, Tibetans split off drom the Han Chinese about 2750 years ago and went on to live in high altitudes.

Natural selection helped Tibetans to evolve to adapt to high altitudes with several mutations occurring in their genes which are mostly related to use of oxygen by the body.

How can cells from the same organism have such different shapes and functions?

Answers

Answer: As each cell differentiates, the DNA changes so that each type of cell has different DNA once it reaches maturity. Mutations in the cells’ nuclei lead to new combinations of DNA, resulting in different shapes and functions in the different types of cells.

Answers

Answer :-

The process of inhaling oxygen rich air and giving out Carbon dioxide is called breathing.This exchange of oxygen and carbon dioxide is called respiration.Every 3 to 5 seconds, nerve impulses stimulate the breathing process, or ventilation, which moves air through a series of passages into and out of the lungs. The respiratory system works with the circulatory system to provide this oxygen and to remove the waste products of metabolism.

Why is a single base insertion or deletion likely to drastically change how the rest of the genetic code is read?

Answers

It will shift the reading frame by one base, altering how DNA is translated because it is read as codons (triplets of bases). Single base insertions or deletions are most influential near the beginning of a gene.

The genetic code is of utmost importance as a slight change in it can change the characteristics of an organism. Just like that base insertion or deletion can cause shifting of frame and can result in a change of the nucleotide sequence causing mutation.

What are the types of mutation?

Mutation is any change in the genetic sequence that can lead to changes in the genome.

It can be of the following types:

Germline mutation: In gametes, germline mutations occur. Other cells in the body experience somatic mutations.Chromosomal alterations: these are mutations that change the structure of the chromosome.Point mutations: it affects only one nucleotide.Frameshift mutations: these are nucleotide additions or deletions that cause a shift in the reading frame.

Thus, base insertion or deletion likely to drastically change how the rest of the genetic code is read as it result in frameshift mutation.

If 15% of a particular DNA strand are nucleotides containing cytosine, what percentage of the DNA molecule would contain thymine

Answers

Answer:

35%

Explanation:

To make a DNA helix, two DNA strands are required. They are connected by the nitrogenous bases on each strand. Each type of nitrogenous base is complementary to another type: cytosine (pyrimidine) pairs with guanine (purine) and thymine (pyrimidine) pairs with adenine (purine). This means they only bond with their pair.

For every cytosine, there must be a guanine bonded to it. So, if 15% of the strand is cytosine, another 15% must be guanine.

Since,

15% + 15% = 30% and 100% - 30% = 70% ,

30% of the DNA strand consists of the cytosine-guanine pair and 70% of the DNA strand consists of the adenine-thymine pair.

Since,

70% / 2 = 35% ,

70% is made up of equal parts adenine and thymine, 35% of the DNA strand must contain thymine.

What is the perimeter of the resulting shape?Round your answer to the nearest hundredth.Also please tell me how you did it.... During the Han dynasty, how did the area that made up China change? How did this change occur? Memories of a MemoryHave you ever witnessed something amazing, shocking or surprising and found when describing the event that your story seems to change the more you tell it? Have you ever experienced a time when you couldn't really describe something you saw in a way that others could understand? If so, you may understand why some experts think eyewitness testimony is unreliable as evidence in scientific inquiries and trials. New insights into human memory suggest human memories are really a mixture of many non-factual things.First, memory is vague. Imagine your room at home or a classroom you see every day. Most likely, you could describe the room very generally. You could name the color of the walls, the floors, the decorations. But the image you describe will never be as specific or detailed as if you were looking at the actual room. Memory tends to save a blurry image of what we have seen rather than specific details. So when a witness tries to identify someone, her brain may recall that the person was tall, but not be able to say how tall when faced with several tall people. There are lots of different kinds of "tall."Second, memory uses general knowledge to fill in gaps. Our brains reconstruct events and scenes when we remember something. To do this, our brains use other memories and other stories when there are gaps. For example, one day at a library you go to quite frequently, you witness an argument between a library patron and one of the librarians. Later, when telling a friend about the event, your brain may remember a familiar librarian behind the desk rather than the actual participant simply because it is recreating a familiar scene. In effect, your brain is combining memories to help you tell the story.Third, your memory changes over time. It also changes the more you retell the story. Documented cases have shown eyewitnesses adding detail to testimony that could not have been known at the time of the event. Research has also shown that the more a witness's account is told, the less accurate it is. You may have noticed this yourself. The next time you are retelling a story, notice what you add, or what your brain wants to add, to the account. You may also notice that you drop certain details from previous tellings of the story.With individual memories all jumbled up with each other, it is hard to believe we ever know anything to be true. Did you really break your mother's favorite vase when you were three? Was that really your father throwing rocks into the river with you when you were seven? The human brain may be quite remarkable indeed. When it comes to memory, however, we may want to start carrying video cameras if we want to record the true picture.Which words from the text describe what our brains use to fill in gaps in memory? Blurry image General knowledge Individual memories True picture hello people ~.
