Scientists study DNAto see the genetic changes that occur through generations.
Well a hypothesis is guess about an experiment and how it works or is preformed. If your supporting one then you agree with how its done and how it works and you got good results. If you fail a hypothesis that means you most likely tried and didn't succeed or didn't get the results you wanted. Sorry if this is confusing the question kinda confused me.
Strawberries are very marketable horticultural crops, they can suffer from diseases and insect attacks, they are susceptible to both heat and cold.
The other reason is they could study a strawberries DNA so it could provide the farmer or plant breeder with keys on how to successfully overcome limitation for strawberry production
During the day, plants produce oxygen by splitting water molecules in the light-dependent reactions of photosynthesis.
Light-dependent reactions occur in thylakoid membranes of chloroplasts and begin with the absorption of light energy. This energy (together with water and photosystems) is used for the production of ATP and the reduced electron carrier NADPH which are necessary for the next stage of photosynthesis. Oxygen is released.
At the same time, plants use cellular respiration to produce some of the carbon dioxide needed by the light-independent reactions to make sugars.
Cellular respiration is a chemical reaction of plants where they use glucose and oxygen to produce carbon dioxide and water and release energy.
During the night, plants produce carbon dioxide, but not oxygen because only cellular respiration takes place.
There is no sunlight at night, so only the cellular respiration occurs.
Answer:
13000 would be avalable because 10% is taken every time it is eaten so 65,000 with 10% taken out twice (20% of 65,000) is only 13,000 kcal available to the secondary consumers.
