Order the following terms as they would occur in a typical stretch reflex. Some items may be placed equivalently (in sequential order from left to right); some events may occur simultaneously (statements overlapping).
1. Muscle stretch
2. Muscle spindles are activated
3. Sensory neurons transmit afferent impulses
(This two together in the same colon, one below to other)
4. Interneurons send inhibitory impulses to antagonistic motor neurons
5. Extrafusal fibers of the stretched muscle are excited
(This two together in the same colon, one below to other)
6. Efferent impulses cause the stretched muscle to contract
7. Efferent impulses to antagonistic muscles are reduced

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave

idk lol use google m8
