Answer:
There are many functions of the circulatory or cardiovascular system. It pumps blood to the heart, transports nutrients and oxygen to cells, and helps provide nourishment to the body. Without it, our body would not be able to fight off diseases or stabilize temperature and pH. It also provides fluid balance.
Explanation:
Answer:
<u><em>Renewable energy</em></u> is energy generated from natural resources such as sunlight rain and wind.
B
The net result of excretion of H+ in the urine is the __conversion of CO₂ to H₂CO₃__ within the blood.
Explanation:
Excretion of H+ ions from the blood via urine means decreasing the H+ content in the blood. This consequently means the blood pH rises ad becomes more basic (remember H+ ions are responsible for acidity for a solution). For the body to maintain the homeostatic pH of between 7.35 and 7.45, the carbonic anhydrase activity will increase hence dissolving more CO₂ into the blood plasma to form carbonic acid (H₂CO₃). Carbonic acid dissociated fast into H⁺ and HCO₃⁻. The H+ from the dissociation replenishes the H⁺ to the right concentration.

Answer:
thermal energy - produced by the movement of heat
radiant energy - produced by the movement of photons
electrical energy - produced by the movement of electrons
sound energy - produced by vibrations of particles
Explanation:
Thermal energy is also known as heat energy. It occurs when heat is transferred in an object.
Radiant energy involves the movement of photons (particles with electromagnetic energy)
Explanation:
The lipstick from the crime would be crushed and dissolved in an appropriate liquid solvent. The lipstick would then be placed in one of the ink spots on the starting / base line of the paper. Another spot would be created for the lipstick with which it is being compared with.
The paper chromatogram would then be placed vertically on a solvent that acts as the mobile phase. After some time, when the solvent reaches the solvent front of the paper chromatography, by capillary action, the chromatogram can be removed and left to dry.
Bands will have appeared on the chromatography paper formed from the different components of the lipstick. The bands of the lipstick from the crime scene and that with which it is being compared to are observed. If the bands are all aligned, horizontally, then this means it is a complete match. The lipstick must have been the same used at the crime scene.
