What gas must be present for the aerobic breakdown of glucose to occur?
Oxygen, the final electron acceptor in aerobic respiration.
What must happen in order for evolution to exist?
Without heredity what use would there be to selection and why evolution? Just take beneficial mutations in the germ line for example. No heredity and nothing to enter the populations gene pool and no evolution. No heredity and there would be no variation in populations and the first environmental challenge would carry your population to extinction.
What pigment is needed to carry out the chemical reactions of photosynthesis?
chlorophyl and also carotenoids, xanthophyls..
Which substances are needed for respiration?
In order for cellular respiration to occur, glucose and 2 ATP molecules are needed to start glycolysis. In order for the next stage of respiration to occur, the Krebs Cycle, oxygen must be present, otherwise fermentation occurs and there is a buildup of ethyl alcohol and/or lactic acid.---------------------------------------------------------------------------------------The above is over complex.For respiration one needsa fuel (sugar from food)and oxygen with which to burn the fuel.One then also needs a mean of removing the waste products produced by burning the fuel.
What is the correct order of stages which must have occurred in evolutionary history for complex cells to have evolved?
The emergence of the first cell is believed to have occurred 3.8 billion years ago. Atmospheric conditions and the appearance of the macromolecules may have started cell evolution.
What are the conditions that must be present in order for each process to occur?
poo on bread
How much energy ATP is needed for osmosis to occur?
The cell does not need to use any ATP in order for osmosis to occur.
What does an energy diagram give?
It shows the energy requirements needed in order for a reaction to occur.
What gas must be present for the aerobic breakdown of glucose to occur?
Oxygen, the final electron acceptor in aerobic respiration.
What are the steps of stellar evolution in order?
You can find an overview of stelar evolution in the Wikipedia article entitled "Stellar evolution".

chlorophyl and also carotenoids, xanthophyls..
What must be available in order for photosynthesis to occur?
In order for photosynthesis to occur, CO2 must be captured from the environment and broken down into carbon and Oxygen via sunlight. The carbon is used for the plant while the oxygen is released.
What is a egg cell in the female?
The egg cell, also called the haploid cell, is the female gamete. A pair of gametes, egg and sperm, are what are needed in order for reproduction to occur.
How can you use the word thrive in a sentence?
In order to thrive, ancient civilisations needed to be founded near rivers or water sources.The population began to thrive.
In order for evolution by natural selection to occur what has to happen?
There must be genetic variation, the variation must be heritable, and there must be differential reproduction (due to competition).
Which substances are needed for respiration?
In order for cellular respiration to occur, glucose and 2 ATP molecules are needed to start glycolysis. In order for the next stage of respiration to occur, the Krebs Cycle, oxygen must be present, otherwise fermentation occurs and there is a buildup of ethyl alcohol and/or lactic acid.---------------------------------------------------------------------------------------The above is over complex.For respiration one needsa fuel (sugar from food)and oxygen with which to burn the fuel.One then also needs a mean of removing the waste products produced by burning the fuel.
