True
Term
All prokaryotes cause disease in one or more host organisms
Definition
False
Term
The hereditary material in Achaea, Bacteria and Eukaryotes is DNA

True
Term
A common feature of the prokaryotes is an absence of a true nucleus.-
Definition
True
Term
Koch’s postulates can be summarized by stating that a single disease is caused by a single isolatable prokaryotic species

False
Term
If the number of chromosomes sets in the plant embryo is 2, the number of chromosomes sets in the endosperm is 4
Definition
False
Term
The surface tension property of water is a property used by plants for transport of nutrients
Definition
True
Term
Early mammalian embryos are more similar to early dish embryos than they are to adult primates
Definition
True
Term
Protists have nerves that coordinate muscular contractions
Definition
False
Term
A biological species is any group of organisms that shares at least one segment of identical DNA

False
Term
Ferns cannot be a source of carbohydrate for any other organism
Definition
True
Term
One will find essentially the same number and similar shaped skeletal bones in chimpanzee and humans
Definition
True
Term
All animals with hair are classified as mammals
Definition
True
Term
All animals have nerves that coordinate muscular constrictions
Definition
False
Term
A biological species is any group of organisms that shares at least one segment of identical DNA

True
Term
Both monocots and dicots are angiosperms
Definition
True
Term
A major challenge for a terrestrial plant is the ability to acquire and retain water
Definition
True
Term
Most plants contain more protein than carbohydrates and cellulose
Definition
False
Term
Seed dispersal in plants is aided by modifications derived from the ovary of the plant
Definition
True
Term
An example of Gymnosperm would be a pine tree

False
Term
Insects and other arthropods have a ventral nerve cord
Definition
True
Term
A single pea or bean or corn kernel are seeds and contain both the plant zygote as well as nutrients for the embryo
Definition
True
Term
All vertebrates possess a notochord and are classified as chordates
Definition
True
Term
The bronchial slits present in fish embryos are also present in the neck region of mammals at a comparable early stage in the embryonic development
Definition
True
Term
The largest number of different species of animals are found in the vertebrates
Definition
False
Term
At an early stage the mammalian embryo has rudimentary multiple arm and leg outgrowths
Definition
False
Term
Most plants use a special one way valve that enables them to pump water from the ground to the leaves
Definition
False
Term
D.W Thompson’s ideas are helpful in understanding how different species have comparable anatomical parts but with different shapes
Definition
True
Term
Changes in the morphology of a species are observed at a very late step in embryogenesis, after the late stage embryo has completed the formation of all normal structures
