ANTONII [103]3 years ago
6 0

The correct answer is option C

Epinephrine  leads to  constriction in blood vessels and causes dilation of  blood vessels in the skeletal muscles and the liver. Also being a stress hormone it increases blood pressure, heart rate, and glucose from energy stores and produces constriction in the smooth muscles.

The seven-spotted cockroach is a nocturnal species that burrows under leaf litter during the day.
djyliett [7]

Answer: C. is less likely to be eaten by a predator.

Explanation:

The adult seven-spotted cockroach is the prey of various other insects including beetles so mimicking the pattern of a beetle would send a message that it is a beetle and because the chemical irritant that the beetle has makes it get avoided by others, the cockroach gets avoided by other insects too who don't want to be sprayed.

Of course this does not always work but it works for the most part and ensures the cockroach's survival.

Second-order neurons of ascending pathways that contribute to sensory perception terminate in the ________. Second-order neurons
madam [21]

Answer:

The correct answer will be option-Thalamus

Explanation:

The somatosensory pathway is the pathway which sends the receptor generated sensory impulses mostly the temperature and touch to the central nervous system.

The pathway is composed of three types of neurons called primary order neuron, second-order neuron and tertiary order neuron.

The second-order neuron receives the signals from the first-order neurons and carries the signals to the relay part of the brain called thalamus. The thalamus is present in the forebrain region of the brain where it receives, analyses and sends the signals to the different region of the cerebral cortex.

Thus, the thalamus is the correct answer.
