<em>Examples of a nonspecific external response to infectious agents and harmful bacteria are the following;</em>
Mucus, saliva, and tears.
They are nonspecific external responses that help to prevent pathogens from entering our bodies.
The specifics contain types of enzymes that break down the bacterial cell walls. An external response of Mucus tends to trap pathogens as well.
<span>During the luteal phase of the ovarian cycle, progesterone secretion peaks and estrogen levels decrease. along with these changes, there is a corresponding increase in a woman's basal body temperature. In this phenomenon, i</span>t is not the increase in progesterone, but the decrease in estrogen that may signal an increase in overall body temperature. This is because the decrease in estrogen reduces the negative feedback signal to the hypothalamus, the thermoregulator for the body. The result is an increase in overall basal body temperature.
Krill should be ur answer hope this helps! have a nice day
Answer: The Answers are, A: happens all the time, D: can be caused by genetic drift, and E: can be caused by natural selection.
It is because of the different neurotransmitters and their receptors.
Sympathetic stimulation of arterioles in skeletal muscle is mediated by epinephrine acting on its β-adrenergic receptors.
Sympathetic stimulation of vasoconstriction occurs as a result of activation of α-1 adrenergic receptors by norepinephrine released by post-ganglionic sympathetic neurons.
