One structure that can be found is most plant cells is chloroplast. A plant cell may have around 0 to 20 chloroplast, depending on their location in plant or their function.
Chloroplast is the structure that photosynthesis occurs. Photosynthesis is the method that plant make food for themselves. They turn sunlight into food such as starch.
Plants are autotrophs, which means they make food themselves, they don't need food from other sources like animals. Therefore, chloroplast is not found in animal cells because we are heterotrophs, we feed on other food.
Around 100,000 years ago there was a second hominine species closely related to modern humans, Homo <span><span>neanderthalensis,</span><span> or commonly called the Neanderthal</span>.</span> Recent studies of neanderthal DNA have shown that there is 3-4% of their genes in modern humans outside of Africa, mostly from Europe, including the ones for adapting to the cold and vitamin D absorption.
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical chemical energy that can later be released to fuel the organisms activities.
Answer:
Reducir las actividades humanas.
Explicación:
Reducir el uso de combustibles fósiles, el uso de vehículos que funcionen con electricidad y plantar más plantas y árboles son las acciones que propondría para ayudar a que la biosfera y sus ciclos no se vean afectados. La biosfera se ve muy afectada debido a las actividades humanas, por lo que para conservar la biosfera y mantener su ciclo, tenemos que reducir las actividades humanas que causan más daños a la biosfera.
