Mutated gene
A mistake by cellular machinery, or damage from an environmental agent such as radiation may produce a mutated gene which is a permanently altered segment of dna.
A gene mutation is a perpetual change in the DNA sequence that forms a gene which makes the sequence different from what is present in most people. Gene mutations can be classified into; hereditary mutation (changes inherited from parents) and somatic mutation (changes caused by environmental factors such as ultraviolet radiation from the sun).
The choices are not given so it is best to discuss what is a facilitated diffusion. It is a type of diffusion where it involves a spontaneous passive transport of molecules or ions across a biological membrane via specific transmembrane integral proteins. It is a process that requires the supply of added energy.
Answer:
The carbon, oxygen, and nitrogen cycles are all biogeochemical cycles. They show the movement of elements through living and nonliving components of the Earth. Carbon, oxygen, and nitrogen, are essential components of life that pass through organisms and nonliving components, but are never used up.
Explanation:
example on edge.
Answer:
The animal cells produce the collagen but the plant cell does not produce collagen that responsible for producing the complex structure of protein and carbohydrates that is called extracellular matrix cell. Collagen is an important protein that provides strength to the structural integrity. On the other hand, the plant has not collagen so they have their extracellular supportive structure. The cell wall is so rigid and covered by the cell that protects it that provides shape and support to it. The plant cell also made up of molecules and these are called cellulose. These cellulose structured into the fibers that are called micro-fibrils
