Answer:
Energy Conservation
Explanation:
Energy Conservation involves using less energy service in an effort to reduce the amount of energy being consumed.
Julie reduces the energy she uses on a normal day by turning her lights off when they are not in use. This will save the amount of energy that would be wasted when the lights are turned on when not needed by Julie. Also, when she unplugs all electronic devices at night, energy is conserved. Julie has conserved energy in these simple acts of hers by reducing wastage, and thereby reduced the pressure on the demand for more energy. By so doing, the need for energy service is reduced which in turn would have positive impact on the environment.
Environmental quality is improved as energy conservation reduces the need for energy services.
Explanation:
There are two compositions in blood.
1. Plasma (55%)
2. Blood cells (45%)
Again Blood cells is divided into:
RBC ( Red blood cell)
It transports oxygen for respiration.
WBC ( White blood cell):
They help in the formation of antibodies to fight against germs and bacteria.
Platelets:
It plays major role in healing of the wounds.
Bottom of the meniscus is the best answer for most liquids. Another correct answer would have been the center of the meniscus.
They have a light complexion, may have not wore sunscreen, or was in direct contact with the sun all day.
A. A describes the effect of light intensity on photosynthesis.
Answer: A
Explanation:
In plants and other primary producers, photosynthesis is a biological mechanism that is vital to energy production. Energy-containing carbohydrates are derived from light, water and carbon dioxide in the form of glucose molecules.
The waste product oxygen is released as a result. Photosynthesis depends on many variables, including:
carbon dioxide concentration,
ambient temperature
and light intensity
It is a rate-limited reaction. Since photons or particles of light provide the energy required for the reaction, high intensities of light increase the photosynthetic rate. From the graph shown, as the intensity increases steadily, so does the rate- but at too high of an intensity, it ceases to affect the rate of photosynthesis, which becomes constant or plateaus.
Beyond this point, either the supply of carbon dioxide or the temperature limits the reaction. For instance, at high intensities tissues may even be damaged by high temperatures or heat.
