• heterosexual

• isosexual

• sexual

which example represents a DISADVANTAGE of asexual reproduction?

• Genetic variety slowly causes hundreds of species of beetles to form from a single species

• a single antibiotic is able to quickly and easily kill millions of genetically identical bacteria

• millions of bacteria are quickly produced by cell division, in one afternoon in a jug of milk that has been left on the counter

• Male anglerfish must live on larger females as parasitic mate, since they encounter other anglerfish so infrequently in the deep ocean.

Which type of reproduction is MOST advantageous for the production of a wide variety of organisms in an individual species?

• budding

• fragmentation

• binary fission

• sexual reproduction

What is one distinct DISADVANTAGE of sexual reproduction?

• organisms that sexually reproduce do not produce much genetic variety

• Sexual reproduction, unlike asexual reproduction, can rapidly produce too many new offspring

• sexual reproduction requires two individuals, which may be difficult for endangered or uncommon species of organisms

• sexual reproduction produces offspring that are all equally vulnerable to the same diseases, predators, and other environmental pressures

Yeast cells reproduce quickly by budding. This is a form of _______________ reproduction so all the yeast cells____________.

• sexual; are unique

• asexual; are unique

• asexual; are identical

• sexual; differ from the parents

Many flowering plants have very colorful petals. What is the main purpose of these colorful petals?

• to protect the plant from predators

• to capture sunlight for photosynthesis

• to distract birds from eating the seeds

• to attract insects that pollinate the flower

Sexual reproduction is important for the survival of the species. It is important for ALL BUT ONE of these reasons. That is

• promotes genetic variability among offspring

• causes new mutations to occur in the offspring

• it is necessary for the survival of the individual

• it is more beneficial for the species than the individual

Which of these is a characteristic of sexual reproduction?

• it takes place in all cells of the body

• it forms exact copies of the parent cell

• It results in offspring with genetic variation

• it requires only one parent to form a daughter cell

Tags

In sexual reproduction, offspring are genetically different from the parents. This is because

• reproduction occurs very rapidly

• only one parent is involved in reproduction

• combined genes are received from both parents

• there is less variations in daughter organisms
