a)
To determine:
The structural and functional joint for label 1 in the given figure.
Introduction:
Joints are the place where two bones join in a body. There are two types of joints in the body, structural joints and functional joints. Structural joints classify the joints based on the material they are composed of. Functional joints classify the joints based on their functioning and movement.
a)

Explanation of Solution
The structural type of the joint is fibrous type and the functional type is synarthrosis. In fibrous joints, two bones are joined by fibrous connective tissues. Synarthrosis is a type of joint that is immovable. The joint in the skull is immovable hence is synarthrosis.
1. Structural type − Fibrous type and functional type − synarthrosis.

The structural and functional joint for label 2 in the given figure.

b)

Explanation of Solution
The structural type of the joint is cartilaginous type and the functional type is amphiarthrosis. Cartilaginous joint is the joint where two bones join together by cartilage or hyaline. There is some movement in such joints. This joint is amphiarthrosis as this joint has very little mobility.
2. Structural type − cartilaginous type and functional type − amphiarthrosis.

Joints are the place where two bones join in a body. There are two types of joints in the body, structural joints and functional joints. Structural joints classify the joints based on the material they are composed of. Functional joints classify the joints based on their functioning and movement.
d)

Explanation of Solution
The structural type of the joint is gliding synovial type and the functional type is diarthroses. In gliding synovial joint, two bones join together at a flat surface and are free to glide over each other in any direction. The diarthrosis joint makes the bones join each other by fibrous joint capsule. This joint is filled with synovial fluid.
4. Structural type − gliding synovial type and functional type − diarthroses.

To determine:
The structural and functional joint for label 5 in the given figure.
Introduction:
Joints are the place where two bones join in a body. There are two types of joints in the body, structural joints and functional joints. Structural joints classify the joints based on the material they are composed of. Functional joints classify the joints based on their functioning and movement.
e)

Explanation of Solution
The structural type of the joint is hinge synovial type and the functional type is diarthroses uniaxial. In hinge synovial joint the movement is allowed in one plane only. Here two or more bones join together with articular surfaces. This joint is diarthrosis uniaxial as the movement is in one plane only.
5. Structural type − hinge synovial type and functional type − diarthroses uniaxial.
f)
To determine:
The structural and functional joint for label 6 in the given figure.
Introduction:
Joints are the place where two bones join in a body. There are two types of joints in the body, structural joints and functional joints. Structural joints classify the joints based on the material they are composed of. Functional joints classify the joints based on their functioning and movement.
f)

Explanation of Solution
The structural type of the joint is pivot synovial type and the functional type is diarthroses biaxial. In pivot synovial joint, the axis of articular surface and longitudinal axis of the bone are parallel to each other. This joint is diarthroses biaxial in function, that is, this joint only allows bending and straightening of the bones.
6. Structural type − pivot synovial type and functional type − diarthroses biaxial.

To determine:
The structural and functional joint for label 7 and 8 in the given figure.
Introduction:
Joints are the place where two bones join in a body. There are two types of joints in the body, structural joints and functional joints. Structural joints classify the joints based on the material they are composed of. Functional joints classify the joints based on their functioning and movement.
g)

Explanation of Solution
The structural type of the 7thjoint is synovial type and the functional type is diarthroses biaxial. The synovial joints are the most movable joints in the body and in these joints synovial fluid is filled. This joint is diarthroses biaxial in function, that is, this joint only allows bending and straightening of the bones.
The structural type of the 8th joint is hinge synovial type and the functional type is diarthroses uniaxial. In hinge synovial joint the movement is allowed in one plane only. Here two or more bones join together with articular surfaces. This joint is diarthrosis uniaxial as the movement is in one plane only.
7. Structural type −synovial type and functional type − diarthroses biaxial.
8. Structural type − hinge synovial type and functional type − diarthroses uniaxial.

To determine:
The structural and functional joint for label 9 in the given figure.
Introduction:
Joints are the place where two bones join in a body. There are two types of joints in the body, structural joints and functional joints. Structural joints classify the joints based on the material they are composed of. Functional joints classify the joints based on their functioning and movement.
h)

Explanation of Solution
The structural type of the 9th joint is ball and socket synovial type and the functional type is diarthroses multiaxial. Inball and socket synovial joints ball-shaped surface of a bone gets fit into a depressed surface of another bone. This joint is capable of moving in various directions. Moreover this joint is diarthroses multiaxial in function.
7. Structural type − ball and socket synovial type and functional type − diarthroses multiaxial.

- Use 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.

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.

- Molecular 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?
