The direct source of energy to move the sailboat is probably wind, since wind is what pushes the sail of the sailboat, which is what propels the sailboat forward.
Hope this helps!
Answer:
One reason that Organism A and Organism C will be placed in different groups will be due to their MODE OF NUTRITION.
As described in the question, Organism A has an autotrophic mode of nutrition which means that it has the capability to produce its own food. Organism C is a heterotroph which means it cannot produce its own food and hence will have different properties as compared to the organism A.
The answer is: A. collecting data
During this process , researchers would use their observational skills and record every notable occurrence that happen to the variables.
The focus on this process is simply to add all relevant data without making any analyzation. That process come later on after the researchers started to change the variables in order to see whether it would create a correlation.
Answer:
the average percentage of energy lost as heat
Explanation:
An energy pyramid (also called trophic pyramid) is a graphical representation that exhibits how energy flows at each trophic level in a particular ecosystem. In an energy pyramid, it is possible to determine how much energy is available at each trophic level and how energy flows from producers (e.g., photosynthetic plants) to primary consumers (e.g., herbivores), then from primary consumers to the next trophic level (e.g., carnivores), and so successively to all major trophic groups (e.g., higher carnivores). During this chain, energy is lost as heat when it is transferred to the next level, and the average percentage of energy lost increases at each trophic level, thereby less and less energy is available to major trophic groups.
Answer:
The answer is B.
Explanation:
A is incorrect because water is a molecule with covalent bonds.
C is incorrect because water is <em>very</em> much polar, since Oxygen has a relatively higher electronegativity than Hydrogen (so the difference of their electronegativities would be greater than 0.3 and less than 1.7).
D is incorrect because the bonds between elements in the water molecules is not hydrogen bonding since water is a molecule in its own right, with strong bonds.
