The answer is False. The location of the continents has a great effect on their climate. Because of their distance from the equator which is the closest point to the sun.
Answer:
more cell types are needed to perform specialized functions in multicellular organisms
Explanation:
Cells in a multicellular organism differentiate to produce more cells that perform specialized functions. Each cell type in a multicellular organism has special features that enable it to perform a particular function effectively. In plants, cell differentiation occurs at the stem and root. The meristematic cells differentiate into either an epidermal, parenchymal or a vascular tissue depending on location.

Called solar system because Sun is biggest and heaviest
Solar means sun planets revolve about (travel in circles around) the sun path a planet travels is called its orbit earth is the 3rd closest planet to the sun all the planets go around in the same direction (like clockwise or counterclockwise), in roughly the same plane, but at different speeds planets close to sun move fast, far out move slower closer a planet is to the sun, the hotter it is, more or less.
The above is only approximately correct scientifically, but could be good enough for grade school. Look up "solar system" in wikipedia for more details and accuracy.

Answer:
A. donation of excited electrons by chlorophyll a to a primary electron acceptor
Explanation:
Photosystems are structures located at the thylakoid membrane that act to harvest energy light in order to convert it into chemical energy. Each photosystem is composed of a light-harvesting complex and a core complex, which in turn is composed of a reaction center. The photosynthetic reaction centers are multi-protein complexes that use light energy to catalyze the electron transfer across the chloroplast thylakoid membrane against a thermodynamic gradient. Moreover, antenna pigments are pigments that capture the energy from photons in order to transfer energy to other pigments in the photosystem (e.g., chlorophyll B and carotenes are antenna pigments, whereas chlorophyll A is the core pigment). Light energy absorbed by antenna pigments in the photosystems is transferred to the reaction center chlorophyll A molecules, thereby exiting electrons in the reaction center. A reaction center consists of two chlorophyll A molecules, which donate electrons to the primary electron acceptor.
