Answer:

blue is the most efficient while green is the least efficient

Explanation:

It is well known that different photosynthetic pigments can absorb light at different wavelengths. Thus, the amount of light absorbed during photosynthesis depends on the color of the source light. The leaves have green color because chlorophyll is a photosynthetic pigment that absorbs light at all wavelengths and reflects green light. The best wavelengths are those at 430–450 nm (blue range) and 600–700 nm (red range), thereby photosynthesis is most efficient when plants are illuminated by light sources that emit blue and red lights. Moreover, sources that emit light at the green wavelength are least efficient for photosynthesis.

What evidence supports the LAW OF CONSERVATION OF ENERGY?

photoshop1234 [79]

Answer:

Taking into account photosynthesis, the evidence that best supports the law of energy conservation is energy is absorbed by chlorophyll and becomes chemical energy during photosynthesis (option 2).

Explanation:

Plants are autotrophic organisms, characterized by synthesizing their own nutrients by converting solar energy into chemical energy through photosynthesis.

During the process of photosynthesis, chloroplasts are capable of absorbing solar energy and converting it into glucose. This process involves the conversion of one type of energy into another.

With respect to the law of conservation of energy, it is necessary to consider:

In the universe there is a constant amount of matter and energy, which is neither created nor destroyed, but transformed.
Energy in an isolated system does not vary, unless it comes into contact with another system.
The amount of energy that is absorbed and obtained is equivalent.

In photosynthesis, the chloroplast is not an isolated system, but has contact with the outside and is capable of absorbing the energy of the sun. This energy will be used to obtain a product, glucose, in an amount proportional to the amount of energy absorbed.

Regarding other options:

1. In photosynthesis, it is not mechanical energy that is transformed into chemical energy.

3. Oxygen is a product of photosynthesis, during the process of chemical energy synthesis, from the combination of carbon dioxide, water and solar energy.

4. It is true that the sun gives off light energy that is absorbed by plants, but it does not explain how this energy is transformed into chemical energy.

Answer:

In which class of elements is there a greater range of properties, the metals or the nonmetals? Give an example to support your answer. Non-metals have greater range of properties given that they exist as solids, liquids and gases. And also that they can polymerize, crystallize and form organic compounds.
