Question 3

Evolutionarily related species that live in extremely inhospitable environment, also referred to as __

Answer 3

Archaea, or extremophiles

Question 4

example fo extremophiles

Answer 4

Acidophile- acid loving
thermophiles- high tempt
Methanogens- convert co2 and h2 into methane

Question 5

how many prokaryotes are identified

Answer 5

6000

Question 6

most complex eukaryotic cells are found where

Answer 6

protists

Question 7

have contractile ribbon in the stalk and a large macronucleus

Answer 7

Vorticella

Question 8

pathogens consisting of a small, naked RNA molecule, which can cause disease by interfering with gene expression

Answer 8

viroids

Question 9

types of viral infections

Answer 9

1. Lytic infection- after infecting the host, the host cell lyses and releases more virus
2. Integration-virus integrates its DNA (provirus) in host cell’s chromosome

Question 10

example of multicellularity that has risen from single-celled organism

Answer 10

Volvox

Question 11

major challenge in artificial organ development

Answer 11

Biocompatibility

Question 12

Strategies to combat biocompatibility

Answer 12

1/ Tissue engineering- enhanced cell culture
2. Making replacement organ- relies on ability of cells to self-assemble into 3D aggregates or organoids.
