Pre-Lab Questions Select the correct answer for each of the following questions:Fibrous joints are structural types containinga. cartilage
b. dense fibrous connective tissue.
c. synovial membranes.
d. synovial fluid.

Introduction :
The connection between two bones is termed as joint. The fibrous joint abundantly contains collagen. These joints are immovable, thus are called fixed joints. The fibrous joint is present between skull bones and called suture. There is no space or cavity in fibrous joint.
Answer to Problem 1PL
Correct answer :
The correct answer is option (b) dense fibrous connective tissue.
Explanation of Solution
Explanation/justification for the correct answer :
Option (b) dense fibrous connective tissue. The fibrous joints are immovable consisting of dense fibrous connective tissue. The immobile nature of such a joint is due to no space or cavity between bones. The fibrous joints are gomphoses, syndesmoses, and sutures. So, the correct answer is option (b).
Explanation for incorrect answer :
Option (a) cartilage. The cartilage is flexible and soft connective tissue present in knees, ankles, and elbow. Hyaline cartilage is present at most of the joints. Cartilage is present only in the cartilaginous joint. So, this is an incorrect option.
Option (c) synovial membrane. The synovial membrane is present in the synovial joint and acts as a shock absorber. The inner surface of the synovial joint is lined by synovial membrane. So, this is an incorrect answer.
Option (d)synovial fluid. The synovia or synovial fluid is secreted by the synovial membrane. This fluid acts as a lubricant, nourisher and shock absorber for bones. It reduces the friction between cartilages. So, this is an incorrect answer.

- What is a gain of function mutation?arrow_forwardMolecular Biology Question: Please help. Thank you Is Southern hybridization's purpose detecting specific nucleotide sequences? How so?arrow_forwardUse the following information to answer the question(s) below. Martin Wikelski and L. Michael Romero (Body size, performance and fitness in Galápagos marine iguanas, Integrative and Comparative Biology 43 [2003]:376-86) measured the snout-to-vent (anus) length of Galápagos marine iguanas and observed the percent survival of different-sized animals, all of the same age. The graph shows the log snout-vent length (SVL, a measure of overall body size) plotted against the percent survival of these different size classes for males and females. Survival (%) 100- 80- 60- 40- 20- 0+ 1.9 T 2 2.1 2.2 2.3 2.4 2.5 2.6 2.7 Log SVL (mm) 19) Examine the figure above. What type of selection for body size appears to be occurring in these marine iguanas? A) directional selection B) stabilizing selection C) disruptive selection D) You cannot determine the type of selection from the above information. 3arrow_forward
- 24) Use the following information to answer the question below. Researchers studying a small milkweed population note that some plants produce a toxin and other plants do not. They identify the gene responsible for toxin production. The dominant allele (T) codes for an enzyme that makes the toxin, and the recessive allele (t) codes for a nonfunctional enzyme that cannot produce the toxin. Heterozygotes produce an intermediate amount of toxin. The genotypes of all individuals in the population are determined (see table) and used to determine the actual allele frequencies in the population. TT 0.49 Tt 0.42 tt 0.09 Refer to the table above. Is this population in Hardy-Weinberg equilibrium? A) Yes. C) No; there are more homozygotes than expected. B) No; there are more heterozygotes than expected. D) It is impossible to tell.arrow_forward30) A B CDEFG Refer to the accompanying figure. Which of the following forms a monophyletic group? A) A, B, C, and D B) C and D C) D, E, and F D) E, F, and Garrow_forwardMolecular Biology Question. Please help with step solution and explanation. Thank you: The Polymerase Chain Reaction (PCR) reaction consists of three steps denaturation, hybridization, and elongation. Please describe what occurs in the annealing step of the PCR reaction. (I think annealing step is hybridization). What are the other two steps of PCR, and what are their functions? Next, suppose the Tm for the two primers being used are 54C for Primer A and 67C for Primer B. Regarding annealing step temperature, I have the following choices for the temperature used during the annealing step:(a) 43C (b) 49C (c) 62C (d) 73C Which temperature/temperatures should I choose? What is the corresponding correct explanation, and why would I not use the other temperatures? Have a good day!arrow_forward
