Answer: Solar panels are made up of silicon cells. This because silicon has high ability for conduction and this make it to be able to convert sunlight into electricity. It is in solar cells has impurities and great chemical properties which make it to be to convert sunlight to electricity.
Silicon
Explanation:
Silicon is an element with atomic number 14, it is a non metal and crystalline solid. It has blue grey metallic lustre. Silicon is made with impurities in solar cells and has special chemical properties to convert sunlight into electricity. It is a semiconductor, a material that can act as a conductor and insulator.
When light interact with silicon cells, it make electrons to be in motion and initiate the flow of electricity, it is called photovoltaic effect.
Silicon alone is not used, it used with metal casing and wiring to ensure proper electric flow.
The answer is mutualism.
Mutualism is a relationship between two different species in which both species benefit. In clownfish - sea anemone relationship, the clownfish is protected from predators by the sea anemone, so the clownfish benefits from this relationship. The sea anemone gets more prey thanks to a coloration of the clownfish, so the <span>sea anemone also benefits from this relationship. Since both species benefit, their relationship is an example of mutualism.</span>
Answer:
<u>bone marrow</u>
Explanation:
Bone marrow are specialized highly vascular fibrous tissues found within the spongy or cancellous parts of the bone. They compose hematopoietic cells which give rise to platelets, leukocytes and erythrocytes. The stem cells are pluripotent meaning they can self- Renewal reproducing another cell identical to themselves and have limited differentiation meaning they can generate one or more subsets of more mature cells but cannot form extra-embryonic tissues.
The water in a reservoir behind a dam is an example of potential energy.
