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.

<h2>Endothermic Process</h2>
Explanation:
An example of endothermic process is :
Heat is needed for water to boil.
Endothermic process can be defined as a process in which heat energy is absorbed from the surrounding that bring about changes in the molecular level like breaking chemical bonds, inter-molecular force of attraction etc.
Boiling of water is an endothermic process because during this process water absorbs heat , its kinetic energy increases and then it boils.
Answer:
B) nuclei of gland cells.
Explanation:
DNA carries the blueprint for the production of all the proteins including enzymes in human beings. Humans are eukaryotes and their DNA is present in the nucleus of their cells. All the cells that make the complex human body are derived from division in the zygote and therefore, are genetically identical and have the same DNA.
However, gene expression is regulated by the expression of specific genes in specific cells and at a different time of developmental stages. Amylase is the enzyme that digests starch in humans. Amylase is secreted by salivary glands. So, the nuclei of these glands would have genetic information for the synthesis of amylase.
Answer:
False
Explanation:
Eukaryotes include animal cells which do not have chloroplasts
