一、是非题(正确请画O，错误请画X；每题2分，共20分)
1.Animals are multicellular, heterotrophic eukaryotes with tissuses that
develop from embryonic layers.
2.Gram-positive bacteria have simpler walls with a relatively large amount of
peptidoglycan.
3.Amoebic dysentery caused by Entamoba histolytica is the third-leading cause
of death due to eukaryotic parasites, after malaria and schistosomiasis.
4.Meiosis and fertilization do not occur in protists, the sources of genetic
variation in protists's populations are transformation and transduction.
5.Echinoderm's development is characterized by indeterminate cleavage, and its
mouth forms from the blastopore.
6.In contrast to the lytic cycle, which kills the host cell, the lysogenic
cycle allows replication of the phage genome.
7.The fossil record of the early Cenozoic documents the rise of large
mammalian herbivores and predators as mammals began to exploit the vacated
ecological niches.
8.Extremophiles including extreme halophiles and extreme thermophiles are
assigned to domain Bacteria.
9.Protists called euglenozoans belong to a clade that includes photosythetic
autotrophs only.
10.Molluscs and arthropods have an open circulatory system in which the
tissues and organs are bathed in hemolymph.
二、填充题(请填入正确英文术语，每格2分，共30分)
1.The first eukaryotes acquired mitochondria by engulfing an(1)by(2).
2.The molecular phylogeny assigns the animal phyla that are not in
Deuterostomia to two taxa:the(3)and the(4), members belonging to the latter
molt as they grow.
3.The evolutionary adaptations that meet the challenge posed by the
relationship of surface area and volume are similar. Structures that maximize
surface area through(5), folding, branching, and (6)have an essential role in
biological systems.
4.Viruses are made up of(7)enclosed in a (8) and sometimes further wrapped in
a membranous envelope.
5.Prokaryotes play a major role in chemical recycling. For example, (9)
prokaryotes function as (10), breaking down dead oragnisms as well as waste
products and thereby unlocking supplies of elements.
6.Protists play key roles in ecological communities, teo key roles are(11) and
(12).
7.Phylum(13)includes both parasites and free-living species also named as
roundworms.
8.Sponges represent a lineage that originates near the root of the
phylogenetic tree of animals；thus, they are said to be (14).
9.Malaria caused by the parasite(15)has rivaled tuberculosis as the leading
cause of human death by infectious disease.
