Answer:
1. Protein - build lean muscle and strengthen tendons
2. Lipids - insulation and long-term energy
3. Carbohydrates - provides quick, easily digested energy
4. Nucleic Acids - repair and replicate DNA and RNA
Explanation:
a. Think of protein as what helps your muscles grow and strengthen
b. Think of lipids as fats (blubber, the extra fat, helps insulate seals from the cold)
c. carbohydrates are found in starch and bread products, and are used to help build up energy prior to marathons.
d. nucleic acids - think of nucleus; it is where genetic material is located, and also where DNA and RNA is located.
B. chloroplast carrries out photo synthesis
Answer:
True.
Explanation:
Earthquake proof buildings are those which have the ability to stand during an earthquake. Shock absorbers that is present between the building and the ground motion, able the building to remain upright during an earthquake. The shock absorbers has the ability to absorb all the disturbance produced in the building and for that purpose the building is safe.
Answer:
c. dilated, constricted
Explanation:
During exercise, more energy is required by skeletal muscles. Oxygen is an important component required for energy production hence supply of oxygen is also increased to skeletal muscles. This is done by increasing the blood flow to skeletal muscles since red blood cells carry oxygen. To increase the blood flow, blood vessels in skeletal muscles are dilated so that more blood can reach them.
Blood vessels of digestive system are constricted because during exercise digestion process is not the priority. More blood should reach skeletal muscles than digestive system.
C6H12O6 is the chemical equation for photosynthesis.
