Solutions

Expert Solution

Chegg's guidance allow us to answer first four question. Kindly re post the other.

Answer 3 – The exoskeleton of Arthropoda is composed of calcium carbonate and chitin, a complex polysaccharide.

Answer 4 – Nematodes and Arthropoda have bilateral symmetry which means that their can divide into two equal halves.

Answer 5 – Nematodes have pseudocoelom body cavity as they don’t possess true coelom.

Answer 5 – Arthropods have a modified coelom in which blood and body fluid mix. This shows that arthropod have open circulatory system which possess body cavities called hemocoels.

Imagine a transmembrane protein complex composed of five analogous subunits that together form a hydrophilic pore that spans the cell’s plasma membrane. The pore is formed by five membrane-spanning a-helices, and each one is donated by one of the five subunits respectively. Each α- helix has hydrophilic side chains on one side of the helix and hydrophobic side chains on the opposite side. Propose a possible arrangement of these five α-helices in the membrane.
