Answer:
b) contains hair and arrector pili muscles
c) contains sweat glands
e)contains sebaceous glands
Explanation:
Skin is classified into two sorts: thin skin and thick skin. Thin skin is the transcendent kind of skin that’s covering the human body. It has a moderately thin epidermis and large containment of hair follicles, sebaceous organs and sweat organs.
Some of the attributes of thin skin:
- Thin Stratum corner
- Hair follicles
- Sebaceous organs
- Arrector pili muscles
<em>Stratum corner</em> — the outermost layer of the skin that consists of keratin cells.
<em>Hair follicle </em>— a connective tissue that surrounds hair’s root.
<em>Sebaceous glands </em>— serve to protect the body from microorganisms and they secret the acids that form the acid mantle.It is a thin acid film on the surface of the skin with a role of barrier to microbes that might penetrate the skin.
<em>Arrector pili muscles</em> — tiny muscles that are attached to the hair follicles in mammals.They cause the hairs to stand on end.
Answer:
Electrical energy
Explanation:
A torch battery has chemical energy stored in it. When the battery is connected in a circuit, this chemical energy is changed into electrical energy, which is then carried by the electricity from the battery to a light globe where it can be changed into light.
The northern lights, or aurora borealis, offer an entrancing, dramatic, magical display that fascinates all who see it — but just what causes this dazzling natural phenomenon?
At the center of our solar system lies the sun, the yellow star that sustains life on our planet. The sun's many magnetic fields distort and twist as our parent star rotates on its axis. When these fields become knotted together, they burst and create so-called sunspots. Usually, these sunspots occur in pairs; the largest can be several times the size of Earth's diameter.
At the center of the sun, the temperature is 27 million degrees Fahrenheit (15 million degrees Celsius). As the temperature on its surface rises and falls, the sun boils and bubbles. Particles escape from the star from the sunspot regions on the surface, hurtling particles of plasma, known as solar wind, into space. It takes these winds around 40 hours to reach Earth. When they do, they can cause the dramatic displays known as the aurora borealis. [Infographics: How the Northern Lights Work & Anatomy of Sun Storms & Solar Flares]
