Explanation:
This question asks us which process involves the chloroplast.
In plants, algae, and some bacteria, a process called <u>photosynthesis</u> occurs. This process takes place in the <em>chloroplasts. </em>In the process, the organism takes light energy from the sun, carbon dioxide, and water, and turns it into glucose and oxygen.
The glucose that is made becomes the food and energy for the organism. In another process, called cellular respiration, the sugar is turned into ATP, a kind of useable energy.
The best answer choice is B. Conversion of light energy to chemical energy. The chloroplasts convert light energy to sugar, and the sugar becomes chemical energy.
Answer:
C
Explanation:
An element is a material that consists of a single type of atom. Each atom type contains the same number of protons. Chemical bonds link elements together to form more complex molecules called compounds. A compound consists of two or more types of elements held together by covalent or ionic bonds.
Answer:
Maintaining the balance of fluids in the body. Binding in moisture when necessary and preventing moisture loss.
Regulating body temperature: it insulates our body, conserves heat in cold conditions and perspires to cool the body down when it gets hot.
Sensing pressure and pain: absorbing shock and alerting us to danger.
Guarding the whole body from external aggressors.
Explanation:
A polar substance has a dipole. A dipole is formed by two or more atoms having different electronegativities. The electrons tend to stay more on oxygen than the hydrogens and therefore, the 2 hydrogen atoms develop a partial positive charge and the oxygen atom develops a partial negative charge.
