Where is the gastrocnemius vein in relation to the femoral vein?

A. Lateral

B. Distal

C. Superior

D. Ventral

Answer Explanation:

The gastrocnemius vein is found in the calf. The femoral vein is found in the proximal anterior thighs/pelvis.

Since the gastrocnemius vein is found below the femoral vein it is distal or inferior to the femoral vessel.

Therefore, the Correct Answer is B.

Q #1: Your class is competing with another class to determine who has the best plant color. Your class decides to test a couple of solutions to determine which would be best for overall plant color before competing. Starting with four sets of four plants, the class decides to water each set with a different solution. They water them once a week with 200ml of the following solutions: water, diet soda, 1% bleach solution, and a 1% salt solution. All plants are placed in the window that receives the recommended amount of light. After a month of testing, your class notices that only two plants are alive, but one of those two does not look healthy. Based on these results, which of the following would be a good hypothesis to design the next experiment around?

A. Plants need more than 200 mL of liquid per week.

B. Salt has no impact on plant health.

C. Salt contains useful nutrients for plants.

D. A combination of the solutions tested will produce healthier plants.

Answer Explanation

Since only 2 out of the initial 16 plants survived the whole month, it would be reasonable to test variables that were shared by all the plants. As such, the amount of liquid the plants need would be a good follow-up experiment. It is not specified as to which plants survived, so there is not enough information to think that testing the impact of salt is warranted. Additionally, since almost all the plants died, it is not reasonable to assume that a combination of the solutions would have an impact.
Q #2: What type of mutation is represented by the following sequence? Original: 123456 Mutated: 154326

A. Breakage

B. Deletion

C. Insertion

D. Inversion

Answer Explanation

An inversion mutation is represented in the sequence 1 5 4 3 2 6. An inversion error is a type of mutation where an entire sequence of DNA is reversed. In this case, 2 3 4 5 has been reversed to 5 4 3 2.

Breakage, choice A, in a gene can mess up its function entirely or lead to a translocation of genetic information. Choice B, deletion, is when a section of DNA is omitted or lost.

Choice C, Insertion, is when an extra base pair is added to a DNA sequence. Deletions and insertions can lead to a frameshift effect where entire sequences are thrown off because one nucleotide is wrong.

This could result in coding for the wrong amino acid and non-functioning proteins.
Q #3: How many tissue layers does the uterus have?

A. One

B. Two

C. Three

D. Four

Answer Explanation

The uterus has three layers. The inner layer is called the endometrium. The middle layer is called the myometrium. The outer layer of the uterus is called the serosa or perimetrium.
