Delimiter between question and answer:

Tips:

  • No column headers.
  • Each line maps to a question.
  • If the delimiter is used in a question, the question should be surrounded by double quotes: "My, question","My, answer"
  • The first answer in the multiple choice question must be the correct answer.

A plant, for example, may be more likely to mutate to a new form with more branches than would a vertebrate because it is easier to produce that kind of change in the development of a plant. What type of constraint is this?
developmental?
Adaptations in nature are not perfect, for various reasons. Give atleast one reason
time lag, developmental constraint, genetic constraint, historical constraint
Is perfect adaptation possible?
No
A possible example of concept is bird feathers: although obviously valuable for flight, it has been suggested that they were originally an adaptation for insulation
preadaptation
What are the three theories have been put forward to explain the existence of adaptation?
supernatural creation, Lamarckism, and natural selection
What form of adaptation does the stick insects shows?
Camouflage
What form of adaptation does this Papilio butterfly shows?
Mimicry
When a lion hunt is successful, does the genus Felis benefits? (Y/N)
Yes
Adaptations evolve because they increase the replication of genes. (T/F)
True
Group selection, in which selection produces adaptations for the benefit of groups of unrelated individuals, is thought to be a weak force.
True
In organisms like humans, with separate germ and somatic cell lines, selection between cell lines is a strong force. (T/F)
False
True or False. The discussion of units of selection aims to find out which level natural selection directly acts on, and which ones it affects only incidentally.
True
Does natural selection ever favor groups, rather than individuals?
No
It refers to behaviour by an individual that increases the fitness of another individual while decreasing the fitness of the actor.
Altruism
It produces a distortion in normal Mendelian segregation, so that chromosomes bearing this gene are over-represented in an organism's offspring.
Segregation distortion
In biology, what is the basic level of organization?
organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere
