<em>Muscle cells are excitable, meaning they react to stimuli. They may shorten and create a pulling force because they are contractile. Locomotion, facial expressions, posture, and other voluntary motions of the body are all made possible by the contraction of skeletal muscle, which is connected to bones.</em>

<h2>Problem of protein alters the movement of Ions </h2>
Explanation:
- Proteins are tiny machines that do explicit occupations inside a cell. The directions for building every protein are encoded in DNA. Proteins are gathered from building squares called amino acids.
- The CFTR protein is comprised of 1,480 amino acids. When the CFTR protein chain is made, it is collapsed into a particular 3-D shape. The CFTR protein is formed like a cylinder that experiences the film encompassing the cell, similar to a straw experience the plastic top on a cup.
- In individuals with CF, changes in the CFTR quality can cause the accompanying issues with the CFTR protein:
- It doesn't function admirably
- It isn't delivered in adequate amounts
- It isn't delivered in any way
- At the point when any of these issues happen, the chloride particles are caught inside the cell, and water is never again pulled in to the space outside the cell. When there is less water outside the cells, the bodily fluid in the aviation routes gets got dried out and thickens, making it smooth the cilia. The cilia can't clear appropriately when thick, clingy bodily fluid overloads them.
Answer:
Scientists once thought the most fundamental building block of matter was a particle called the atom. Now we know that the atom is made of many smaller pieces, known as subatomic particles. Every atom contains a central core called the nucleus, made of particles called protons and neutrons.
High concentration and passive transport
Answer:
The factors which remained constant are as follows -
- material used as the membrane
- amount of substances used
- number of trials
The factors which have shown variation are as follows -
- molecule size (large starch molecules vs. small glucose molecules)
- whether the molecules diffused through the membrane (tubing)
Explanation
Some factors with in the experiments remained constant from the point of starting of the experiment to its end. While some factors were varied to study its impact on the experiment rate of progression or on the final product formed. Thus , out of the following given factors, the ones that remained constant are -
- material used as the membrane
- amount of substances used
- number of trials
The factors which have shown variation are as follows -
- molecule size (large starch molecules vs. small glucose molecules)
- whether the molecules diffused through the membrane (tubing)
