09 Multiple Choice
Look at the organisms below. What do these organisms have in common?
1.skeletal structure
2.constant body temperature
3.presence of spinal cord
4.pattern of symmetry
Answer:
D. Pattern of symmetry
Explanation:
The bird, insect and the giraffe all have the same pattern of symmetry or body plan.
They have bilateral symmetry. This is because of a vertical plane is run through each of them, from top to bottom, the body parts would be divided into two. That is each side would have equal arrangement of the different parts that makes up the organism. This is why it is referred to as bilateral symmetry.

Which correctly describes cytokinesis and the phase it occurs in the cell cycle?
A. It is the process in which DNA is replicated to make two copies, and it occurs in the interphase of the
cell cycle.
B. It is the process in which DNA is replicated to make two copies, and it occurs in the mitotic phase of
the cell cycle.
c. It is the process in which the cytoplasm of a cell divides to make two daughter cells, and it occurs in
the interphase of the cell cycle.
D. It is the process in which the cytoplasm of a cell divides to make two daughter cells, and it occurs in
the mitotic phase of the cell cycle.
Answer:
D
Explanation:
Cytokinesis occurs after telophase in the cycle. During cytokinesis a contractile ring forms around the cell membrane splitting the cell into two separate cells which each contain a full set of DNA

Explanation:
Volcanic eruptions are the result of the movement of tectonic plates. Which of the following most affects the movement of these tectonic plates?
options
A Heat within Earth
B The gravity of the Moon
C Radiation from the Sun
D The movement of ocean currents
Answer: A. Heat within the Earth
Explanation: the earth’s crust floats on liquid rock. The convection currents caused by the Earth’s rotation cause movement at the surface.
which of the following is a role of helper t cells
A( To ingest pathogens
B( to destroy cells that have been infected by viruses
C( to activate B Cells
D( to increase blood flow
According to the _______ hypothesis, the moon formed far away from the earth and was later captured by the earth's gravity.
The most popular hypothesis for the moon's origin is the _______.
Telescopes can be engineered to gather light from any portion of the _______.
In 2021 the James Webb Telescope will begin operation focusing on infrared wavelengths and must be kept extremely _______.
Scientists estimated the age of the universe to be nearly _______ billion years using Hubble's pictures and images from the Wilkinson probe.
Answer:
The correct answer is -
1. capture
2. the giant impact hypothesis
3. electromagnetic spectrum
4. cold
5. 14
Explanation:
Capture hypothesis is presented by the Urey and was dominant up to the 60s which states that the Moon was an asteroid-like wandering structure that formed somewhere far in the solar system and was captured by Earth's gravity while it was wandering.
The most dominant and popular theory for the origin of the moon is the giant impact hypothesis says that it is formed from the debris left after the collision of the earth and Theia a Mars-sized body.
Telescopes are tools engineered for collecting light from any part of the electromagnetic spectrum.
Scientists estimated that the age of the whole universe to be nearly 14 billion years with the help of Hubble's pictures and pictures from the Probe of Wilkinson
1. capture
2. giant impact hypothesis
3. electromagnetic spectrum
4. cold
5. 14
6. The moon's mass is much lower than the earth's; therefore, its gravity isn't strong enough to hold an atmosphere. This lack of an atmosphere and the moon's small size allowed it to become cool enough to the point at which it completely solidified. Thus, the moon doesn't have any plate tectonic activity.
In dragons, a gene on chromosome 1 codes for wing color and a gene on chromosome 2 codes for body color. Draw out the stages of meiosis for these two chromosomes from a dragon that is heterozygous for both traits. Make sure that, within your drawing, you define your alleles. Also, in your drawing include all the possible allele combinations of the gametes produced.
Answer:
Possible gametes produced - (XY) (xY) (Xy) (xy)
Explanation:
For Wing color -
Dominant allele = X
Recessive allele = x
For Body color -
Dominant allele = Y
Recessive allele = y
Parent genotype - XxYy
Possible gametes produced - (XY) (xY) (Xy) (xy)

100 POINTS!!!!
Reference the article on the first page to answer these questions:
https://www.pharmaceuticalonline.com/doc/the-potential-of-personalized-medicine-0001
1. Summarize the following points of the article. (2 points)
a) What is personalized medicine?
b) What areas of human health are likely to benefit from these new technologies?
2. How did the sequencing of the human genome change the way doctors are analyzing personal disease and risk? List the five points made in the article. (5 points)
3. What are the concerns of Dr. Ray Woosley regarding these new developments? (2 points)
4. You might be able to have your entire genome sequenced by a commercial company for less than $5,000 in the near future. Make a list of the potential benefits and concerns of genome sequencing. (3 points)
5. What are the five challenges to personalized medicine that are discussed in the article? ( 5 points)
6. Much of the research being done in this area is based on commercial products. The scientists performing the experiments are often employees of the company. Companies that are developing these new technologies hope to create products to be sold for profit. How does the involvement of commercial pharmaceutical companies influence the use of this and other new technology? (2 points)
7. The article states, “The number one concern that individuals have today is that information about past health or prediction of future health based on genetic tests may be used by a health insurance company to increase rates or deny healthcare coverage. Also, people are concerned that employers might use genetic information to make decisions about hiring, firing, and job assignments.”
a) Using at least two of the advantages or disadvantages discussed in the article, state your opinion about the use of the information contained in a person’s genome to treat disease. (4 points)
b) Do you think this new technology should be controlled or regulated? How would you address the potential for loss of genetic privacy? (2 points)
Answer:
1
A) A medicine that is personalized towards an individual's DNA.
B) These new technologies will be a benefit towards human health because they will be more effective and will not be as hazardous.
2) The sequencing of the human genome changed the way doctors are analyzing personal disease and risk because they are now able to diagnose the disease risk factors, provide better treatment for patients, determine which type of disease it is more accurately, how much of a dose of medicine the patient needs, and figure out genetic disorders.
3) He is worried that people might be moving too fast regarding these developments and wants them to proceed slowly and carefully so there is no room for error.
4) Some benefits would be protection from other certain diseases, I can fix any sort of genetic disorder, and order it so I can become stronger. However, I’m concerned that there will be risks in the sequencing process, which will change my genome for the worse.
5) Many potential biomarkers have yet to be verified and qualified for use, the FDA has yet to set a regulatory approval pathway for these products, the success of personalized medicine is contingent the ability of scientists and healthcare providers to capture, manage, store, and provide access to data and medical information, in order for personalized medicine to succeed, healthcare providers, patients, and insurers must learn how it works, and there are many privacy, confidentiality and fair-use concerns.
6 It could influence the use of these technologies because rather than focusing on helping people, they will only think about the money, leading them to do it carelessly and recklessly.
7
A) I think that using the information in a person's genome to treat disease is a good idea because it is much more effective in preventing disease and can fix any sort of genetic disorder much more easily.
B) I think this should be controlled. To address the potential for loss of genetic privacy, make it so that person gives their consent and you only take what is needed without having to look at the whole genome.
