Your skin is an important organ and has several functions. All of the functions below are performed by the skin EXCEPT
A)
makes vitamin D.
B
prevents-dehydration:
C)
maintains body temperature.
D)
works with bones to help you move.
Answer:D
Explanation:
Your skin makes vitamin D
Your skin prevents dehydration
And your skin maintains body temperature. So you are left with D
Answer:
The correct option is D.
works with bones to help you move
Explanation:
Skin is the outer layer of the body and it is the body's largest organ.
It protect the body from heat and other harmful substances.
It is comprises of three layers;
The Epidermis which is the outer layer.
The dermis which is a fibrous later that protect the Epidermis.
The subcutis is the subcutaneous layer that is beneath the dermis.
Function of the skin.
1. It's regulate body temperature
2. It's protect the body from heat and pathogenic entry.
3. It produces vitamin D
4. The skin allow sensations or feelings of touch, heat, and cold.
Therefore;
works with bones to help you move is wrong because it is the muscle that work with the bone.
How are the three intermolecular forces related?
Explanation:
Intermolecular forces are electrostatic in nature and include van der Waals forces and hydrogen bonds. ... The three major types of intermolecular interactions are dipole–dipole interactions, London dispersion forces (these two are often referred to collectively as van der Waals forces), and hydrogen bonds.May 20, 2018
Spheres of Earth Assignment Active Analyzing Sphere Interactions Explain how Earth's spheres may be affected by the droughts brought on by El Niño. Sometimes, the surface of the Pacific Ocean warms up, causing changes in the weather in some areas. This phenomenon is called El Niño. El Niño causes the amount of rainfall in some parts of the United States and South America to increase. It also causes droughts to occur in Southeast Asia and Australia. Droughts occur when an area receives less rain than it normally does over a certain period.

How is the kinetic energy of the particles of a substance affected during a phase change?
A.) Kinetic energy increases during exothermic changes and decreases during endothermic changes.
B.) Kinetic energy decreases during exothermic changes and increases during endothermic changes.
C.) Kinetic energy does not change, but the potential energy does.
D.) Kinetic energy changes in the opposite way that the potential energy changes.
Answer: A. Kinetic energy increases during exothermic changes and decreases during endothermic changes
Explanation: During an exothermic change potential energy is converted to kinetic energy. I hope this is correct. :)
Answer:
C
Explanation:
4.which is a product of the process shown above?
a. carbon dioxide
b. sugar
c. sunlight
d. water
5.where does the energy that drives this process come from?
a. oxygen
b. sugar
c. sunlight
d. water
Answer:
4. b 5.C
Explanation:
Photosynthesis makes sugar for plants and sunlight is the energy used to convert CO2 and water into glucose
The product of the process of photosynthesis is sugar and the energy to dive the process of photosynthesis comes from sunlight.
What is photosynthesis?Photosynthesis is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy through the process of cellular respiration.
Some of the energy which is converted is stored in molecules of carbohydrates like sugar and starches which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.
The process begins with proteins absorbing light energy which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.
