Answer:
Hypothalamus
Explanation:
The hypothalamus is a part of the brain which possesses temperature receptor cells that detect changes in the man’s temperature, thereby sending signals in the form of electrical nerve impulses to the man’s muscles and nervous system, which in turn respond in counteracting the drop in the normal temperature of the body.
Once the muscle cells of this man receive these signals, they produce heat through thermogenesis by shivering when the muscle cells begin to contract. This is one of the mechanisms by which thermoregulation is achieved as controlled by the hypothalamus in the brain of the man.
Well everyone's needs for love and attention are different. It can depend on how you were raised, if you received a lot of attention as a kid, etc. Humans are social creatures so we already crave human interaction. and, going back to how you were raised, even if you were raised quite well and you got enough attention as a kid, it really depends on how people treated you and maybe how many times you've had your heart broken or something along those lines. That need honestly varies from person to person. But I know how it feels, you'll get through it, you'll be okay.
Answer: Skeletal Muscle
Explanation:
Skeletal muscle is a form of "striated" (striped) muscle tissue. It is under the voluntary control of the somatic nervous system. Most skeletal muscles are attached to bones by bundles of collagen fibers known as tendons.
Answer;
An example of positive feedback loop is;
-When a pregnant woman begins to go into labor, the body sends hormones that increase the intensity of the labor contractions.
Explanation;
-Feedback loops are therefore the process whereby a change to the system results in an alarm which will trigger a certain result. The result will then either increase the change to the system or reduce it to bring the system back to normal.
-Feedback loops are important because they allow living organisms to maintain homeostasis (maintenance of internal environment of the body constant).
-A positive feedback loop occurs in nature when the product of a reaction leads to an increase in that reaction. It moves a system further away from the target of equilibrium, by amplifying the effects of a product or event and occurs when something needs to happen quickly.
