Answer:
I'm not sure sorry what type of question Is it?
Chloroplasts are only found in plant cells because it is the organelle that makes photosynthesis possible and it makes food for the plant cells as in it makes its own food and animal cells dont need them because animals eat other animals for that food
Answer:
The elements in increasing order of atomic radius: oxygen, carbon, aluminum, potassium
Explanation:
The distance from the center of the nucleus to the outermost shell of the electron is known as the atomic radius of an element. The atomic radius decreases rightward along each period (row) of the table due to the increase in effective nuclear charge (the charge of the nucleus equal to the number of protons). Across a period, electrons are added to the same energy level and the increasing number of protons causes the nucleus to exert more pull on these electrons, which makes the atomic radius smaller. Atomic radius increases down each group (column) of the periodic table because of the addition of electrons to higher energy levels, which are further away from the nucleus and the pull of nucleus weakens. Another reason for the increase in atomic radius is the electron shielding effect, which is the reduction of the attractive force between a nucleus and its outer electrons due to the blocking effect of inner electrons
While moving from left to right in the second period, c
arbon comes before oxygen and so oxygen will have a smaller atomic radius than carbon. While moving down the periodic table, al
uminum comes before potassium even if they are not in the same period. So aluminum
's atomic radius will be smaller than that of potassium but bigger than that of carbon and oxygen.

Answer: C- glycolysis, krebs cycle, electron transport chain.
Explanation: Glycolysis is a catabolic reaction that comprises of series of steps that breaks down food to give off energy in a form of ATP. Pyruvate is the product of glycolysis together with two ATP molecules. Pyruvate is further broken down by joining the krebs cycle and finally the electron transport chain that transfer electrons using the redox reaction, to reduce NADH to NAD + H and FADH to FAD, creating the final product i.e ATP, Overall one glucose molecule gives 38 ATP molecules in aerobic respiration.
