It is known as hypothesis.
Before experiments, we should set up a hypothesis so that we can expect what happen. But hypothesis does not always has to be right, that's why we have to do experiments to test.
If a hypothesis matches the experiment result, a theory is formed. If it does not, we should adjust different variables in the experiment and set a new hypothesis again.
Genotype is what you can see on an organism and phenotype is what can’t see
Answer:
ATP releases energy (ATP + H2O --> ADP + P + energy) and in order for things like active transport to happen ATP is required.
Answer:
Plants must have evolved in a manner where they require less water and nutrients as these two were the only limiting factor and carbon dioxide was in abundance
Explanation:
Some 400,000 years ago, the concentration of CO2 was very high and was near to 1000 ppm. At this high concentration of CO2 the photosynthetic activity of plants becomes very high and thus since 400,000 years ago plants could have evolved in an uncontrolled manner but this does not happened. So the reason behind this is limitation in terms of soil and its constituent’s nutrients availability and also limited supply of water.
Therefore, if plants would have evolved themselves in a manner where they require less water and nutrients then they would have grown limitless.
<span>Epinephrine is most likely to be released into the bloodstream in order to accelerate one's heartbeat. This usually occurs when one is in danger, thus, preparing the individual for a fight-or-flight response. This hormone is also most commonly known as adrenaline as it is secreted by the adrenal glands. </span>
