What is the effect of exercise on carbon dioxide production
seraphim [82]

Answer:

When you exercise, the muscles you use require more energy. When exercise can be sustained, this demand is met primarily by aerobic means. Aerobic energy production in muscles results in increased gas exchange at the lungs, because more oxygen is taken in and more carbon dioxide is released.

A student investigates the effect of temperature on gas production in yeast. The student uses this apparatus to count the number
tigry1 [53]

The effect of temperature on gas production in yeast;

As the temperature gets higher, the yeast will produce more carbon dioxide, until at some point carbon dioxide production will decrease, that is when the yeast cells have become denatured due to the increase in tempmoreerature.

<h3>An experiment to show the effect of temperature on gas production in yeast.</h3><h3 />

If temperatures affect the growth of yeast and the amount of carbon dioxide gas produced then when the yeast is placed for instance in 75 degrees, the carbon dioxide levels will be than the carbon dioxide levels at room temperature (69 degrees), and 40 degrees, because heat activates the enzyme molecules to move faster

Yeast at an optimal temperature to produce the same amount of CO2 as yeast below or above it. ... Enzymes involved in yeast cell metabolism start to denature above-optimal temperatures, resulting in a decrease in both metabolic rate and CO2 production.

the outer planets are mostly formed of lighter elements because these three condense are a ____ temperature
Stolb23 [73]

The outer planets are mostly formed of lighter elements because these three condense are a<u> lower temperature</u>.

<u>Explanation:</u>

The planets based on the location of the sun is divided into two, that is outer planets and inner planets.

The Outer planet which is far from the sun consists of larger quantity of lighter substances such helium, hydrogen, methane which would condense at the lower temperature. And remains gaseous inside the frost line that would exit far away for the sun so the temperature is low and the lighter materials are easier to condense in lower temperature to form terrestrial  rocks.
