Many processes occur in the digestive system .which process is best classified as a physical change
Answers
Answer:
This question lacks options, the options are:
A) Saliva converting the starch molecules in crackers into simple sugars
B) Digestive enzymes breaking down proteins into smaller fragments
C) bacteria converting lactose into simple sugars in the intestines
D) teeth grinding an almond into smaller pieces in the mouth
The answer is D
Explanation:
A physical change is a change that occurs to a substance without altering its chemical composition. A physical change involved a change in the substance's shape, texture, color, state etc. but not the chemical content of such substances.
In this question involving the processes that occur in digestion, a typical example of physical change is "teeth grinding an almond into smaller pieces in the mouth" because the teeth only changes the shape and texture of the almond. It does not affect the chemical composition of the almond fruit. This is also called mechanical digestion.
Note that, other options involving digestive enzymes breakdown are chemical changes because the enzymes breakdown the chemical components of each substance.
Answer: D
Explanation: because you are breaking down food in a physical change

Transmembrane proteins span the width of the cell membranes. Four types of transmembrane proteins are shown in a section of cell membrane.
groene
Although these proteins have different specific functions, they all-
A-stop chemical reactions within the cell
B-synthesize molecules that signal other cells
C- help the cell interact with its external environment
D- remove large waste particles from the cytoplasm of the cell
Answers
Answer:
C. help the cell interact with its external environment
Explanation:
A transmembrane protein (TP) is a type of integral membrane protein that spans the entirety of the cell membrane. Many transmembrane proteins function as gateways to permit the transport of specific substances across the membrane.
Although transmembrane proteins have different specific functions, they always HELP the cell interact with its external environment.
Transmembrane proteins are a broad category of membrane proteins that act as carriers and/or transporters in order to allow the movement of specific substances across cell membranes.
After binding to their specific ligands, the three-dimensional (3D) shape of transmembrane proteins changes in order to allow the movement of molecules and ions through the cell membrane.
For example, aquaporins are a type of transmembrane protein that regulates the entry of water (H2O) molecules into and out of cells.
In conclusion, although transmembrane proteins have different specific functions, they always HELP the cell interact with its external environment.
