C) thyroid hormones increase basal metabolic rate of cells in the body
D) blood vessels dilate and blood is directed to the superficial layers of the skin

Answers

Blood vessels dilate and blood is directed to the superficial layers of the skins is one way in which the body will react to maintain homeostasis.

Homeostasis is the set of self-regulation phenomena that lead to the maintenance of constancy in the properties and composition of the internal environment.

Control in blood flow is a response that reduces heat transfer and therefore maintains body temperature.

Thermoreceptors upon detecting an increase in body temperature, are activated and transmit this information to the hypothalamus that receives the information.

Blood vessels constrict to reduce the passage of "warm" blood to the skin, allowing it to be used in vital organs.

Blood vessels in the skin dilate as a result of increased body temperature, allowing molecules to separate and occupy more space.

In addition, it increases the amount of warm blood that flows from inside the human body, increasing blood pressure and transmitting heat to the outside environment more quickly.

This allows body temperature to be lowered, a notorious consequence of this dilation of the vessels is the reddening of the skin where there is greater flow and transfer of body heat.

Therefore, we can conclude that blood vessels dilate and blood is directed to the superficial layers of the skins is one way in which the body will react to maintain homeostasis.

The answer is D I believe. It is called vasodilation. As the blood vessels dilate and skin is directed to the skin, your body looses heat through skin by convection.

15. Which of the following is not an accurate description of chemical reactions? A. The rates of chemical reactions can vary. B. Chemical reactions that take in energy never need a source of energy to start. C. During chemical reactions, energy can be released or used up. D. During chemical reactions, bonds can be broken or formed.

Answers

The correct answer is "B".
  All chemical reactions require "activation energy". Activation energy can be thought of as kickstarting a chemical reaction. If you consider lighting a match, the match does not spontaneously combust upon its removal from the matchbox. You must kickstart the reaction by heating the chemicals in the match head. This heat is generated by the friction of rubbing the match head against the side of the box.In any case, reactions that take in energy, must take that energy from somewhere, so they absolutely need a source of energy to start, and to continue!

Answers

There are three types of seismic waves. These are classified on the basis of their penetration in the earth's surface and their arrival to seismographs. First are primary waves, which arrive first and penetrate the deepest. Then are the secondary waves, which penetrate less and arrive after primary waves. Finally are the surface waves, which do not penetrate the earth's surface and arrive the latest.
