mutation means
the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes
if the environment changes fast it will cause mutations
Explanation
Answer:
Speed of blood past the constriction becomes two times the speed of blood flow in the rest of the artery.
Explanation:
For an ideal fluid flow condition, the equation of continuity is applicable which means that the flow of any fluid at a given point of time at two different cross section remains same at constant density
Thus,
Substituting the given values in above equation, we get -
Thus, speed of blood past the constriction becomes two times the speed of blood flow in the rest of the artery.
The answer to this question would be endocytosis.
Endocytosis a process to bring outside material into cell. The word "endo" itself mean "inside". This material could be source of energy or microbes that need to be killed. It's opposite would be exocytosis. The word "exo" itself mean "outside".
Both of them is pretty similar because they use vesicle to transport the things that need to be moved.
Answer:
Undifferentiated inner cell mass
Explanation:
Human embryo has two types of cells in its initial stage, trophoblast and inner cell mass. Trophoblast forms the placenta and inner cell mass form the entire human body. Inner cell mass are pluripotent in nature i.e. they can give rise to any body part under right conditions.
Embryonic stem cells are derived from the inner cell mass. They are derived from pre implantation embryo since after implantation the inner cell mass begins to differentiate. Embryonic stem cells can replicate indefinitely without differentiating. They can give rise to all the three germ layers: ectoderm, mesoderm and endoderm. They can treat a number of disorders like genetic disorders, Parkinson's, spinal cord injury, cancers etc.
