1. The correct answer is 4. Carbon can bond to 4 other atoms, exponentially increasing its ability to make different molecules.

2. The correct answer is 3. An organic compound (or molecule) is any atom (usually hydrogen) that bonds with carbon.

3. The correct answer is the third option (8 electrons). Valence electrons in the outer shell are those can form a chemical bond. When (most) atoms have 8 electrons in their outer shell, they are then considered to have maximum stability.

4. The correct answer is 2. These macromolecules all contain carbon and hydrogen, making them organic compounds.

1 - Carbon atoms can bond with many other kinds of atoms to form very stable molecules. 2 - organic molecules . 3 - 8 (full shell) . 4 - i'd say Carbon and Hydrogen

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.

Select all that apply.

Pure water is very close to a pH of 7. The Great Salt Lake (from what I've read about) can range from 8.2 to 7.7 in different areas. Saliva is between 6.5 and 7.5. And ammonia has a pH of 11.
So the items that have a pH between 5 and 8 are pure water, saliva, and possibly the Great Salt Lake.
