Answer:
different proteins
Explanation:
All the cells of the body are derived from same cell still different cells have different characteristics or phenotypes. For example, the hemoglobin is present in RBCs only not in any other cell. This is because of a process called gene expression.
This process regulates expression or repression of different set of genes. This makes embryonic cells to become specialized cells that is to perform a specific function. The gene contains DNA which gets transcribed to RNA and then to proteins. The different proteins provides different specificity to cell.
The correct answer is option C
Epinephrine leads to constriction in blood vessels and causes dilation of blood vessels in the skeletal muscles and the liver. Also being a stress hormone it increases blood pressure, heart rate, and glucose from energy stores and produces constriction in the smooth muscles.
Chlorophyll absorbs energy from sunlight and it also absorbs the red and blue colors so it reflects it as green.
Answer:
Option A is false, the remaining statements regarding cellulose are correct
"Microtubules are directly attached to the outside surface of the plasma membrane to form tracks that help orient the cellulose polymers"
Explanation:
Cellulose is specific to plant cells walls only, animal cells do not contain cellulose. It is produced at the membrane of the cell. The microtubules are actually attached to the inside of the plasma membrane and it helps to orient the cellulose polymers that way. It provides vital structural support to the plant.
Hope that answers the question, have a great day!
