Answer: Chloroplast
Explanation:
The presence of chloroplast would have been the last organelle which appeared in the eukaryotic cell. Chloroplast helps in photosynthesis which means prepare food from the inorganic compounds.
But here the cell obtains energy from the organic compounds which states that there is no need of chloroplast in the cell as they obtain energy by hetero tropic mode of nutrition.
Hence, chloroplast is the correct answer.
Because evolution occurs when something happens, and the organism needs to adapt. Events aren't fixed, and they're definitely not random either
A change in the substance by temp, color,
Ions are elements that are charged, for example Cl- is an ion because it has gained an electronic to become negative and to have a full outer shell of electrons (8 electrons) because of the octect rule. Other examples are Mg2+ and Al3+, which have lost elections to become positive.
An isotope is an element that has the same number of Protons and Electrons, but a diffent number of Neutrons. Because of this, the relative atomic mass of the element changes for example, Carbon. On the periodic table, the relative atomic mass is 12. However isotopes of carbon could be Carbon-14 or Carbon-16. This is because the number of neutrons has increased and so is an isotope of Carbon-12. Isotopes occur naturally and the most common isotope of carbon is Carbon-12. All isotopes of elements have the same properties, only difference is the neutron number
