A student is measuring the effect of different temperatures on the effect of enzymes in biological systems. What temperature ran
viktelen [127]

Answer:

A. 25 °C, 30 °C, 35 °C, 40 °C, 45 °C  

Explanation:

Each enzyme has a temperature at which it works best. In humans and many animals, that temperature is around body temperature (37 °C or 98.6 °F). Most enzymes are denatured and work poorly at 40 °C (104 °F).

That automatically eliminates Option B.

I would pick a temperature close to 37 °C (98.6 °F) and temperatures at intervals above and below that.

Option D is wrong because it includes no temperatures above body temperature.

Option C is wrong, because it includes temperatures of 45 °C and 55 °C, at which the enzymes will be denatured.

That leaves Option A as the best answer. It includes only one temperature above 40 °C.

Tanya is training a turtle for a turtle race. For every 1/6 of an hour that the turtle is crawling he can travel 1/24 of a mile.
frozen [14]

The rate at which Tanya's turtle travels is 0.25mi/hr

This question is from a topic in mathematics called Rate.

<h3>Rate</h3>

This is a ratio in which different terms in different units are compared against each other.

In this question, for every 1/6 of an hour, the turtle is crawling 1/24 of mile.

Data given;

  • 1/24 miles in 1/6 hour

Let's express this mathematically

1/24 mi = 1/6 hr\\x mi = 1 hr\\x = (\frac{1}{24})/(\frac{1}{6})\\x = 0.25mi

What this calculation shows is that the turtle travels at 0.25mi/hr

The rate at which the turtle travels is 0.25 miles in an hour or 0.25mi/hr

For both ectotherms and endotherms, metabolic rate tends to increase as mass increases

As the masses of the dinosaurs increase, how do their metabolic rates change? How does this compare to living animals?

>> As with living animals, the higher a dinosaur’s mass, the higher its metabolic rate.
