Answer:

D. Electrical - electromagnetic and thermal​

Explanation:

Energy is the capacity to do work, and it exists in various forms. Some of its forms are: nuclear energy, solar energy, electrical energy, mechanical energy, sound energy, light energy, heat/ thermal energy etc. These forms can be transformed from one to another. Example is the conversion of electrical energy into light energy and heat energy by an electrical Tungsten-bulb.

A space heater is an electrical device used for generation of majorly heat energy, thus it is powered by electrical energy. Therefore it transforms electrical energy into electromagnetic and thermal.

natta225 [31]

Answer:

Explanation:

The method of reproduction in humans is sexual reproduction: a type of reproduction that occurs when new organisms are produced through the coming together of genetic information from two individuals of different sexes mostly a male and a female (egg cell and the sperm). The genetic information for making the blood cells; the red blood cells genes in particular exists on chromosomes in the nucleus of the sex cells (egg and sperm cell) also called the gametes. Basically, the DNA provides instructions for the production of mostly all of the body's needs.

The genes coding for the sickle cells which is the abnormal red cell is always inherited in the recessive form meaning both parent has to possess one copy each of the defective gene in their DNA. For humans to get one copy of a sickle cell gene and one copy normal gene; it means one of the parents gametes (be it male or female) contributed the defective chromosome and the other normal gene is contributed by the other parent  during copulation giving rise to an individual that is heterozygous for the trait

For example, the sperm cell with the defective gene fertilizes the egg cell that has the normal copy of the gene producing an heterozgous individual.

Hich physiologic change increases cardiac work but does not enhance cardiac output?
Ugo [173]

Increased afterload physiologic change increases cardiac work but does not enhance cardiac output.

<h3>What about cardiovascular system?</h3>
  • Heart and blood vessels, which make up your cardiovascular system, deliver oxygen and nutrition to your body's organs so they can function.
  • Blood vessels also transport waste such as carbon dioxide to be disposed.
  • Conditions affecting the heart or blood vessels are collectively referred to as cardiovascular disease.
  • It is frequently associated with atherosclerosis, an accumulation of fatty deposits in the arteries that increases the risk of blood clots.
  • The heart, blood arteries, and blood make up the cardiovascular system.
  • Its main job is to carry deoxygenated blood back to the lungs and to carry nutrients and oxygen-rich blood to all regions of the body.
  • The most typical cause of coronary artery disease is atherosclerosis, which is a buildup of fatty plaques in your arteries.
  • Atherosclerosis can be brought on by unhealthy lifestyle choices such smoking, being overweight, not exercising, and eating poorly.
