Question

this type of communication involves the use of pheromones (chemicals/scents) that are released to attract a mate, ward off predators, or to alert:

a auditory
b chemical
c kin selection
d imprinting

question 6 (4 points)
this type of behavior balances between benefits of nutrition and cost of finding food, predation, and using up energy to hunt. also called cost - benefit analysis:

a innate
b forging
c cooperative
d learned

question 7 (4 points)
this behavior might decrease an individuals fitness but increase the fitness of others:

a kin selection
b altruism
c agnostic
d foraging

Explanation:

First Question (about pheromones):

The question is about communication using pheromones (chemicals/scents). Auditory is sound - based, kin selection is about favoring relatives, and imprinting is a learning process. Chemical communication uses chemicals like pheromones, so option b is correct.

Innate behavior is inborn, cooperative is about working together, learned is acquired. Foraging behavior involves balancing the benefits of getting food (nutrition) and the costs like finding food, predation risk, and energy use for hunting, which is cost - benefit analysis. So option b is correct.

Kin selection is about favoring relatives (a type of altruism towards kin), agonistic is aggressive/defensive, foraging is about food. Altruism is the behavior where an individual's fitness decreases but others' fitness increases. So option b is correct.

Answer:

b. chemical
