You are called for a young man who was diving head first off a dock into a lake. Bystanders say he struck his head on the bottom

because the water was too shallow. They said he was not breathing when they pulled him from the water and they have been performing rescue breathing for him. He is awake, but he is unable to breathe on his own. What type of damage or injury does this indicate?
A. Closed head injuryB. Open head injuryC. Damage to C3, C4, or C5D. Damage to his thoracic spine

Answer:

Answer is C. Damage to C3, C4 or C5.

Explanation:

C1 - C7 are used to represent the number of vertebrae found at the cervical region of the vertebrae canal or column. The vertebrae column comprises off various vertebrae that protect the spinal cord,which starts from the neck region to the tail region.

The C3, C4 and C5 are at the midsection of the cervical region of the spine , and they provide support for the neck and the head.

These vertebrae contain nerves which if affected will cause a serious pain. which can actually affect his breathing. Because, the spinal nerves around the spinal cord are linked to the brain.

Question 1(Multiple Choice Worth 3 points)
shepuryov [24]

Answer:

1. It involves multiple trials

2. 2 red: 2 white

3. Process 1 describes cloning and process 2 describes artificial selection

4. Furry Feet

5. Large scale insulin could be produced in relatively lesser time

6. A lowercase letter

7. 0%

8. rr

9. 50%

10. The allele for white flowers is recessive in the pea plant

Explanation:

1. Repetition, this means to do over and over. This would involve multiple trials and this is done to test the reliability of the results and determine if the hypothesis holds true or not.

2. If you put your cross in a Punnett square it would look like this:

      R    r                            

r     Rr   rr                          

r     Rr   rr

Based on your problem: R = red; r = white

If the genotype would have a dominant allele (R), then the dominant trait will come out, if it has only recessive alleles (r) then the recessive trait will come out. So as you can see there are 2 red and 2 white. So the ratio would be 2:2 or 1:1.

3. Process 1 is considered as cloning, and to be more specific, reproductive cloning. The aim of this is to produce an offspring that has the same genetic make up as the original or parent organism. Process 2 is an example of artificial selection. This is also known as selective breeding where breeders choose certain traits to pass on to the off springs by selecting the organisms that have the traits desired.

4. Furry feet of polar bears provide them extra traction when they walk on snow. The fur also provides extra warmth. They also have foot pads on the soles of their feet that help them as well. Together, polar bear have something that works like snow boots.

5. Large-scale insulin could be produced in relatively lesser time because bacteria reproduce through asexual means. They produce copies of themselves that are genetically identical. An advantage of asexual reproduction is the process occurs in a much faster rate. With that said, insulin supply would increase, which will help many diabetic patients.

6. Recessive alleles in a genotype are represented by a lowercase letter. On the other hand, dominant alleles are represented by a capital letter. Squares and circles are used in pedigree charts to represent the whole genotype of an organism for a specific trait.

7. The answer would be 0% because cystic fibrosis is a RECESSIVE gene disorder. For it to be expressed or observable in an individual , t<u>hey should have two recessive alleles</u>. As you can see in the end result, none of the offsprings have 2 recessive alleles. The genotype Aa, has a recessive allele, but it will not be expressed because the dominant trait will mask it.

8. When we talk about homozygous, this means the alleles are the same. And when you say heterozygous, this means that the organism would have a dominant and recessive allele. the recessive llele is represented by a lowercase letter. So if the organism is homozygous recessive, the genotype would have two lowercase letters. (rr)

9. The scenario shows the genotype is pp. This means that the pea plant is homozygous recessive. As explained before, recessive traits are represented by lowercase letters. So this would mean that the white color is a recessive trait. The answer would then be the allele for white flowers is recessive in the pea plant.

10. Mitosis and meiosis are both forms of cell division. Mitosis produces daughter cells that are exactly the same as the parent cell, while Meiosis produces daughter cells that are different. They produce what we call haploid cells, which has only half the chromosomes of the parent cell. Gametes or sex cells are produced through meiosis, while body cells are produced through mitosis.

Explanation: We have to elimnate the other answers to figure out which one is correct.

The brain stem is number six

The spinal cord is also number six, but way lower

The cerebrum is like the whole brain

Therefore, leaving us with cerebellum, cerebellum is the correct answer
