Answer:
E) 2
Explanation:
The energy transfer through the food chain is not 100% from one consumer to another, or from the producer to the primary consumer, but instead it is around 10%. This means that if a producer has the 100% of energy, as it is the one that produces it, the primary consumer will only get 10% of its energy while consuming it, while the predator of the the primary consumer will only 10% from the primary consumer, or rather only 1% from the energy of the producer. In this case we have 200 kg of plant material. The plant material represents a producer, thus it is the one with 100% of energy. A herbivore will eat the plant material, getting 10% of its energy, thus this plant material is supporting about 20 kg of herbivore. The predator of the herbivore gets only 10% from the herbivore's energy, or only 1% of the producer's energy, thus only 2 kg of predator can be supported by the initial plant material.
Answer:
ATP, is a molecule called adenosine triphosphate.
This molecule takes part in coupled reactions:This molecule participates in a large number of biochemical reactions, this molecule is the energy contribution of reactions, it appears in the Krebs and glycolysis cycle.
This molecule is a type of nucleotide.
ATP is a nucleotide formed by three phosphate groups and an adenosine. The nucleotide is adenine with three energy-rich phosphate groups.
The independent variable is the amount of water consumed by the football players.
The dependent variable is the football players' endurance, measured by how many times they can run up and down the bleachers before catching their breaths.
The coach's hypothesis was that the more water consumed, the more endurance the players will have.
There is not a control group present in this experiment, but it would be the set of players who did not drink a bottle of water before practice.
The experimental group is the set of players who did drink a bottle of water before practice.
The constants in the experiment are the operational definitions of endurance (how he measures their endurance), the amount of water each player drinks throughout the week, and the players used in the experiment.
The lack of a set control group poses a threat to the accuracy of the experiment's results.
The concentration of salt in water affects the rate of osmosis because it will determine how much water should be transported or excreted or to be taken in. The cellular process is keen to the salt concentration of its system thus making sure to maintain balance between the salt concentration the right amount of water must also be in its area of release for any expected occurences.
Osmosis then is the movement of water particles from which has water and from which has not and to provide it with the sufficient H2O.
Answer:Thirty years ago, 45 out of 200 individuals, or 22.5% of individuals, were at least 1.2 meters tall. Presently, 50.5% of individuals are at least 1.2 meters tall. Meanwhile, individuals below 1.2 meters in height have decreased significantly between the two years of data. This data supports the argument that directional selection is occurring.
