33.What do fungi and arthropods have in common? 34. Each of the following is a general characteristic of bryophytes except 35. A botanist discovers new species of plant in a tropical rain forest. Alter observing its anatomy and life cycle, the following characteristics are flagellated sperm, xylem with tracheid's, separate gametophyte and sporophyte generations, and no seeds. This plant is probably most closely rlated to36. An infectious material is isolated from a nerve cell. It contains protein with amino acid sequences identical to the host protein but no nuclic acids. It belongs to the group 37. When a virus enters the lysogenic stage

Expert Solution

Ans 33. The protective coats of both groups are made of chitin.

Chitin is long-chain polymer of a N-acetylglucosamine (NAG) , a derivative of glucose. It is common raw material for cell wall make up of both fungus and arthropod.

Ans 34. Vascular Tissue.

Bryophytes lack vascular tissue so they also called as 'non-vascular tissue. Vascular system is functions as the pipeline for plants.The primary components of vascular tissue are the xylem and phloem. These two tissues transport fluid and nutrients internally useful for nutrition and development of plants.

Ans.35 : Ferns

Ans 36. Prions

Prions are the isoforms of human proteins which becomes harmful due to misfolding.They are abnormal, pathogenic agents that are transmissible. Prions induce abnormal folding of specific normal cellular proteins which most abundantly in the brain. For ex. Creutzfeldt-Jakob disease (CJD)

Ans 37. The viral genome integrated into the host genome.
