Which of the following statements about focal adhesions is true?
option a: they may act as a type of sensory structure leading to cell growth.
option b: they anchor cells to the substratum.
option c: all of the choices are correct.
option d: they can be rapidly disassembled upon a changing environment.

The correct answer is Option C: "All of the choices are correct".

Explanation:

The term focal adhesions for cell's biology, also known as cell–matrix adhesions or FAs, refers to macromolecular assemblies that allow the interaction of the cells with its extracellular matrix. FAs may act as a type of sensory structure leading to cell growth, as well as to directional movement, differentiation and survival. FAs anchor cells to the substratum, acting as anchoring devices that maintain the cell morphology. FAs can be rapidly disassembled upon a changing environment, adapting to the new conditions of the extracellular matrix.

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.
