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.

Why do we have different time zones
swat32

As Earth rotates, different parts of Earth receive sunlight or darkness, giving us day and night.

What is the function of rhizoids?
Temka [501]
<h2>Rhizoids absorb water and nutrients from the surrounding soil. </h2>

Explanation:

Rhizoids are primitive root like structure in lower plants like bryophytes and sin fungi. Rhizoids are usually unicellular. However many plants exhibit multicellularity. Rhizoids functions as the roots in these plant,by absorbing water and nutrient from the surrounding soil. They may contain enzymes which helps in extracellular digestion in orgsnidm which have saprotrophic  mode of nutrition.Rhizoids provide a little anchorage to the substratum.

alukav5142 [94]

Answer: B. Water breaks down into oxygen molecules for respiration.  


Water is the required for photosynthesis, a process by which plants (terrestrial and aquatic) makes their food by utilizing water as a reactant to produce oxygen and glucose as product. The glucose act as a source of energy for conducting various metabolic processes in plants but oxygen is released in the air.

6CO_2\ \ \ \ +6H_2O\rightarrow\ C_6H_{12}O_6+6O_2\\carbon\ \ \ \ water\ \ \ \ \ \ \ \ glucose\ \ \ \ \ \ \ oxygen\\ dioxide

This oxygen is necessary for terrestrial and aquatic animals for respiration. Therefore, water breaks down into oxygen by the process of photosynthesis, hence water plays important role in respiration in living beings.
