Answer:
Experimental groups: type of dogs
Dependent variable: hearth rate
Independent variable: the amount of caffeine
Explanation:
The dependent variable is the variable being measured or tested in a given study, while the independent variable isn't changed by the other variables. In this case, the heart rate is dependent on the amount of caffeine, which is then the independent variable. The experimental groups are the groups exposed to the independent variable.
Polarity of a molecule does not involve the symmetry of the molecule rather it deals on with the presence of net charges and partial charges. It would be due to the partial charges present in the <span>single myosin molecules that causes its polarity. Hope this helps. Have a nice day.</span>
<h2>Concept of biological species</h2>
Explanation:
- Determine whether peoples from one populace will interbreed with people from the other populace when brought into one another's local environments
- An animal category is a gathering of individual living beings that interbreed and produce fruitful, practical posterity. As indicated by this definition, one species is recognized from another when, in nature, it isn't feasible for matings between people from every specie to create prolific posterity
- Individuals from similar species share both outer and inward qualities that create from their DNA. The closer relationship two living beings share, the more DNA they share for all intents and purpose, much the same as individuals and their families. Individuals' DNA is probably going to be more similar to their father's or mother's DNA than their cousin's or grandparent's DNA. Living beings of similar species have the most significant level of DNA arrangement and, subsequently, share attributes and practices that lead to effective propagation
