Answer:
Explanation:
As one moves down the vertical groupings of elements on the periodic table, it is evident that new shells are being added from top to down.
An atomic orbital is the region of space surrounding the nucleus where there is a high probability of finding an electron.
Down a group, the atomic radius increases as more shells are added to an atom.
Answer:
chloroplast, more precisely in the stroma of the chloroplast
Explanation:
Chloroplasts are a type of chromoplasts that are located in photosynthetic plant cells and green algae.
They can be moved by amoeboid and contractile movements, and placed in the part of the cell that receives the most light. Photosynthetic algae usually have a large chloroplast, but plant cells have a few tens.
The internal medium of the chloroplast is called stroma, and it is composed of a solution of carbohydrates, lipids, protids, nucleic acids, pigments, nucleotides, salts and elements.
Its main function is to capture the light energy and use it in the synthesis of organic matter.
Kinetic energy on mass. gravity, and speed
