What else can I help you with?
What could cause reproductive isolation?
Any factor that in nature prevents interbreeding between individuals of the same species or of closely related species, for example geographic separation is itself a reproductive isolation because is a factor that prevents interbreeding. -extinction of one species -production of infertile offspring -development of physical differences
The developing male reproductive system is most closely associated with what systems?
urinary
What organ in the urinary system is closely associated with the reproductive system?
In the male the penis and urethra are organs that are used in both the urinary and reproductive systems.
What is the differences between geographic isolation temporal isolation and behavioral isolation?
Geographic isolation: a population is separated by distance or some kind of barrier so the members of the population can't interbreed with the main population. Temporal isolation: Two species that breed at different times of the day, season, or year cannot mix their gametes. Behavioral Isolation. Species-specific signals and elaborate behavioral patterns are used by closely related species to insure contact with the proper mate. Birds, mammals, and insects have pre-mating rituals that attract the proper mate. These signals can be chemical or physical in nature. Other organisms pay little or no attention to these behaviors or scents.
What process of meiosis is most closely associated with which human system?
The process of meiosis is most closely associated with the reproductive system in humans. Meiosis is a type of cell division that produces gametes (sperm and egg cells) with half the number of chromosomes as the parent cell, allowing for genetic diversity in offspring.
What body system is most closely associated with transport and delivery?
The circulatory system is most closely associated with transport and delivery in the body. It is responsible for transporting nutrients, oxygen, and hormones to cells, as well as removing waste products from the body.
What are the two kinds of reproductive isolation mechanisms that biologists divide?
Temporal isolation-species mating at different times of the year.Behavioral isolation-mating behaviors in two groups of isolated populations change, thus making individuals from the two groups not attracted to each other.Pollinator isolation-some closely related plant species have flowers that attract different pollinators, preventing the two species from inbreeding.Mechanical isolation-when reproductive organs in closely related species change drastically, making it impossible for one species to mate with another.Gametic isolation-when incompatibilities between the sperm and eggs of closely related species keep them from fusing.Hybrid inviability or sterility-when the egg gets fertilized, the resulting offspring may not live (inviable) or it is sterile.
An American most closely associated with abolition was?
Frederick Douglass was closely associated with abolition.
Which of these themes is most closely associated with imperialism?
Government is most closely associated with imperialism.
Which of these is most closely associated with Darwin?
Natural selection is what is most closely associated with Darwin.
What two body systems work closely together to produce offspring?
The reproductive system. It is different in males than it is females.
Which body system is most closely associated with the production of offspring?
The reproductive system is most closely associated with the production of offspring. It includes organs such as the ovaries, testes, uterus, and fallopian tubes that are responsible for producing and protecting gametes (eggs and sperm) and facilitating fertilization to create new life.
