There are 2 functions for cell surface markers. The first is to recognize the outside cell. The second is to allow the cell to bind to substances outside the cell.
Cell surface markers are proteins expressed on the surface of cells that often conveniently serve as markers of specific cell types. There are different types of cell surface markers. These markers are vital for the human body to function. These markers also vitally affect the functions of other biological systems of other organisms and creatures such as animals.
Answer is C
The hydrogen bond between complementary nucleotides.
As it is the DNA molecule and is double stranded. The complementary strands of DNA attached by the hydrogen bonding between complementary nucleotides (A,T, G, C). Here the Adenine of a strand base paired with the thymine residue of complementary strand by double bond. The guanine and cytosine is paired by forming triple hydrogen bond in the same way.
Answer:
your answer is a
Explanation:
Carbon enters the geosphere through the biosphere when dead organic matter (such as peat or marine algae) becomes incorporated into fossil fuels like coal and organic-matter-rich oil and gas source rocks, and when shells of calcium carbonate become limestone through the process of sedimentation briefly described above. formation of fossil fuels form remains of dead organisms .
Answer:
retrograde axoplasmic transport
Explanation:
The retrograde axoplasmic transport is a type of fast axonal transport that moves the substances at a fast rate by using proteins. These proteins transport the substances along the surfaces of the microtubules of the cytoskeleton of nerve cells. The retrograde axoplasmic transport moves the substances towards the soma or cell body from the terminal ends of the axon. This type of axonal transport mostly moves the substances that are to be recycled or broken down.
