What is the process of chemosynthesis

Chemosynthesis is a biological process that uses inorganic compounds (rather than sunlight as in photosynthesis) as the energy source to convert carbon compounds and nutrients into organic matter. This process is most often found at hydrothermal vents in the deep ocean, but it has also been found deep in caves all over the world.

Apex:Making food energy from ocean chemicals

What is the first organ to develop in the embryo

The first organ to develop in the embryo is the heart. In a fetus, there is a brain, but it isn't fully developed and can't understand signals from the nervous system. Therefore the first functional organ would be the heart. But the first thing to start developing in a fetus is the nervous system. ( no that isn't an organ )

What does a culture medium provide to a living cell

Food molecules called nutrients and water Culture medium provides what makes living cells. This is what keeps living cells functional.

Apex- water

Why are embryonic stem cells useful for medicine
