Positive feedback differs from negative feedback in that one: a. positive feedback systems have only effectors, whereas negative feedback systems have only receptorsb. the positive feedback's effector responses are in the same direction as the initiating stimulus rather than opposite of itc. positive feedback loops are more frequently encountered in the control of homeostasisd. positive feedback benefits the organism, whereas negative feedback is detrimentale. the effector's response increases some parameter (such as body temperature), whereas in negative feedback it can only decrease the parameter

b. the positive feedback's effector responses are in the same direction as the initiating stimulus rather than opposite of it

Explanation:

Both positive and negative feedback have the same components:

1. Stimuli - external or internal

2. Sensors - detect the stimuli

3. Control center - processes the information (CNS)

4. Effectors - activated by control center

Negative feedback loops act to oppose the stimulus.

Unlike negative feedback loops, positive feedback loops amplify the starting signal.

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
