They study and do lots of research
Answer:
Answer B. Endosymbiosis
Explanation:
Early protists were first eukaryotic organisms and had several membrane bound organelles. The anaerobic protists evolved by acquiring purple bacteria. The purple bacteria have the ability to carry out aerobic cellular respiration. The endosymbiont transformed into mitochondria in due course of evolution. Similarly, the photosynthesizing protists were evolved by endosymbiosis of cyanobacteria which in turn was transformed into chloroplast during further evolution.
Answer:
bones
Explanation:
other parts such as skin etc is made up of soft tissue so it decomposes easily
The answer is chloroplasts and mitochondria.
<span>When solar energy in the form of sunlight reaches a leaf of a plant, it passes through the leaf to chloroplasts. Chloroplasts contain pigment chlorophyll which is excited by light. As the result, </span>a series of chemical reactions occur in the chloroplasts and carbon dioxide and water are converted into glucose and oxygen. Now, glucose is broken down and transported into mitochondria where through different processes (Krebs cycle and electron transport chain) energy is produced in the form of ATP.<span>

The process by which molten material moves through the Earth's mantle is known as convection current. This is simply demonstrated within a liquid, in this case molten material, in which the hottest materials rise and the colder materials sink. Convection currents in the mantle are the forces that help move plate tectonics.
