Sorry if this doesn’t help I don’t know if we’re on the same track!! But I hope it worked!!
Answer:
The cytoskeleton is a network of fibers that forms the "infrastructure" of eukaryotic cells, prokaryotic cells, and archaea. In eukaryotic cells, these fibers consist of a complex network of protein filaments and motor proteins that help move cells and stabilize the cell.
Explanation:
Function:
It helps the cell maintain its shape and provides support to the cell.
Various cellular organelles are held in place by the cytoskeleton.
It helps in the formation of vacuoles.
The cytoskeleton does not represent a static structure but is able to disassemble and assemble its parts in order to enable the internal and overall mobility of the cell.
The cytoskeleton contributes to cell migration because cell motility is required for tissue construction and repair.
The cytoskeleton helps transport communication signals between cells.
In some cells, it creates cell bulges, such as cilia and flagella.
Cytoskeletal structure
:
The cytoskeleton is composed of at least three different types of fibers: microtubules, microfilaments, and middle filaments.
These fibers differ in their size, and the microtubules are the smallest and the microfilaments are the thinnest.
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.

Answer:
D) The lac operon will function normally.
Explanation:
- The promoter area can be described as the area that causes the transcription to initiate for a particular gene. Promoters may be near the genes from which they initiate transcription or they may display multiple scenes upstream.
- The lock operon works normally because the promoter area can still enable transcription on many base pairs. Detects repression promoter and works normally.
- so correct option is D) The lac operon will function normally.
