Minerals are rarely used in everyday life true or false

False

Reason: We Use Minerals In our day to day life, when it comes to cooking, or burning. We use Salt to cook amazing meals, and some pots and pans have minerals built in to them so that they last longer over the years you cook with them. When we burn in the fireplace or in the backyard, some of us use coal and light it up, and sometimes, we use minerals to make buildings. In one of my neighboring towns, their City Hall has little mineral pieces built into the City Hall. I hope this helps, and happy holidays! :)

H1: false, the observations of the molecules do not support the hypothesis...

Explanation:

The cell membrane is comprised of a phospholipid bilayer, proteins, and cholesterol. These components help the membrane to maintain its selective permeability and concentration of solutes and water.

The lipid molecules have polar hydrophilic heads and hydrophobic tails. These only readily allow for the movement of small non polar molecules. Other substances, like charged ions and large molecules require transport proteins to move in and out of the cell. Hypothesis: H+ is small and should be able to move freely through the membrane, While glucose is large and cannot move freely

Observing H+, despite being very small these cannot easily pass through the membrane. They require transport proteins called channels for their free movement or passive movement across the membrane.For glucose, these molecules pass through specialized channels in facilitated diffusion. They move down their concentration gradient into the cell. To move out of the cell against its concentration gradient glucose requires ATP for active transport.Cortisol, is a large steroid hormone, taken into the cell by simple diffusion across the lipid membrane, down its concentration gradient.
