<span>What appears to be another given is a plot relating the rate of heatbeat and time. Distance is the integral of speed with respect to time. This corresponds to the area under a v-t graph. Taking the height of the triangle to be 0.75m/s and the base to be 0.32s which gives distance of beat equal to 7.5cm </span>
Answer:
controlling more variables
improving measurement technique
increasing randomization to reduce sample bias
blinding the experiment
adding control or placebo groups
Answer:
Competition, predation, commensalism, mutualism and parasitism.
Explanation:
There are five types of relationships present between organisms such as competition, predation, commensalism, mutualism and parasitism. Competition is a type of interaction between organisms in which both the organisms are harmed. In predation relationship, one organism feed on the other by killing it. commensalism is a relationship in which one is benefited and the other is neither benefited nor harmed. In mutualism relationship, both the organisms or species gets benefit from one another whereas parasitism is a type of relationship in which one organism is benefited and the other is harmed not killed.

The relationship between the garter snakes and rough-skinned newts is their evolutionary race.
Grater snakes are resistant to the TTX (the toxin of the rough-skinned newts).
TTX-resistant snakes (resistance was formed via mutation) cause natural selection to favor ever-more poisonous newts (so they can survive), and the “new” newts drive selection for higher resistance in snakes.
