The answer is DNA Replication. I<span>t must duplicate its chromosones and manufacture the materials needed for cell division</span>
The correct answer is B.chloroplasts.
Chloroplasts are plant’s organelles so they cannot be found in a cell from fingernail. The function of chloroplasts is to convert light energy of the Sun into glucose that can be used by cells and this is possible thanks to chlorophyll found in chloroplast . The entire process is called photosynthesis.
That's true because the basic functions of a multi-cellular plant occur in the cell and like any other cell, unicellular alga are also cells thus basic functions such as respiration, excretion, growth occur in both multicellular organisms as well as unicellular organisms
The Earth's mantle is the layer of rock just below the Earth's crust. Just under the crust, it is solid. It is very hot, and the other part of the mantle is soft, kind of like melted candy.
The Earth's mantle is rock-hard but it actually flows around the outer core, moving about as slowly as your fingernails grow. The mantle tends to be 2,900 kilometers thick, and makes up 84% of Earth's total volume.
