(Circle yes or no for each) a. cross section of the humerus (the arm bone)Yes No b cross section of the large intestine c cross section of a pinky finger d. cross section of a small blood vessel e cross section of a ureter (-0.5 cm in diameter) Yes No 25. For each of the examples given below, is the structure likely to fit in its entirety on a microscope Yes No Yes No Yes No 26. A scientist is interested in developing a tissue that can resist stretch in multiple directions, yet also remains very flexible. Given what is known about the properties of human tissues, describe how the scientist might design such a tissue. impose on cartilage as a tissue? 27 Cartilage is unique as a connective tissue in that it is avascular. What limitations does avascularity impose on cartilage

Explanation / Answer

25. The compound microscope has 4mm diameter for its objective lens. therefore we can see the following slides-

d- cross section of a small blood vessel

the other options include a, b, c and e cannot observe effectively under microscope. That is due to their broad size.

26. Tissue like connective tissues has these two properties. Collagen fibres and white fibrous tissues like tendons are non-stretchable but highly strong and flexible. Theses tissues also present in blood vessel, which is a better example.

27. Avascular means cartilage lacks blood vessels; due to this, cartilages do not have regenerative property. This is its limitation while other connective tissues have.
