Is there any matrix called as zero matrix?
ya yes its there a matrix called zero matrix
What is a zero matrix?
A zero matrix is a matrix in which all of the entries are zero.
What is a sparse matrix?
A sparse matrix is a matrix in which most of the elements are zero.
What is a involuntary matrix?
a squar matrix A is called involutary matrix. if A^2=I
Is it true that the transpose of the transpose of a matrix is the original matrix?
yes, it is true that the transpose of the transpose of a matrix is the original matrix
Name three nonliving substances found outside a cell.?
Body fluids, cellular secretions, and intracellular matrix
What substances are found on cell surfaces?
Living-subclasses and subhyla Nonliving- body fluids, cellular secretions, intracellular matrix
What are the functional roles of body fluids cellular secretions and intracellular matrix play?
Body fluids help transport nutrients, oxygen, and waste products throughout the body, regulate body temperature, and maintain pH balance. Cellular secretions contain enzymes and hormones that regulate cell function and communication. The intracellular matrix provides structural support to cells and helps in cell signaling and movement.
Are eubacteria intracellular or extracellular?
intracellular
Do mollusks undergo extracellular digestion or intracellular digestion?
Intracellular
Is proteins the major intracellular anion?
No; the major intracellular anion is phosphate.
Does lymph includes extracellular fluid or intracellular fluid?
intracellular fluid
What pathogens are intracellular and what are intracellular?
intracellular pathogens can only replicate inside a host cell, whereas extracellular pathogens can replicate independent of the host
A bacterium that can enter the structure of a host cell is called?
An intracellular bacterium.
Why is the intracellular environment considered the sea within us?
The intracellular environment is often referred to as the "sea within us" because it is made up of a fluid matrix (cytoplasm) that surrounds and bathes organelles within the cell, much like the sea that surrounds organisms in the ocean. This fluid environment is essential for various cellular processes to occur, such as nutrient transport, waste removal, and biochemical reactions.
What is the primary site of the intracellular digestion?
The primary site of intracellular digestion are the lysosomes.
Recent evidence shows that the extracellular matrix can take part in regulating th expression of genes a likely possibility for this might be what?
One likely possibility for how the extracellular matrix regulates gene expression is through the interaction of matrix proteins with cell surface receptors, leading to signaling pathways that control gene transcription. Additionally, physical cues from the extracellular matrix, such as stiffness or topography, can influence chromatin structure and gene expression. Overall, the extracellular matrix provides a dynamic microenvironment that can modulate gene expression in cells.
