Diferences in mating patterns of montane and prairie voles (promiscuous and monogamous, respectively) is caused by different expression patterns of ADH receptor. If researchers inserted the gene for ADH receptor into the brain of the montane vole in patterns that matched the prairie vole, which of the following would most likely occur, and what type of behavior would this indicate? A) Montane voles would remain promiscuous; this is an innate behavior. 1) Montane voles would become monogamous: this is an innate behavior. C) Montane voles would remain promiscuous: this is a learned behavior. D) Montane voles would become monogamous; this is a learned behavior. 9. As a population approaches its carrying capacity, how does its growth change? A) The growth rate slows until N is 0. B) The growth rate slows until N is close to K. C) The growth rate slows until N is close to r. D) The growth rate stays the same. 10. Tropical leaf cutter ants collect leaf cuttings which they transport to special underground chambers. There, they chew the leaves to create nursery beds on which they grow a species of fungus they use for food. When ant queens disperse to establish new colonies, they carry the fungus with them, dispersing it as well (this benen in the fingus) In the ants' nest, the fungus is at risk of being destroyed by another Amgal species that is able to grow in the same habitat, using the same limited Pesources. On their bodies, the ants carry and provide a home for bacteria that produce antibioties the ants use to kill this second Angus and thereby protect their Rood supply. In this system, the relationship between the leafoutter ants and their Mingal food species ist A) Interspeeinte competition. C) predation D) parasitism E comensalim A species Andamental miehe: A) is smaller than its realized niche. 11) in what is actually occupied by that species. C) in clerermined by competition between species. D) has the necessary resources and conditions for survival. is always cupied in full by most species.
