Answer:
Why not use adult stem cells instead of using human embryonic stem cells in research? Human embryonic stem cells are thought to have much greater developmental potential than adult stem cells. ... However, a newer type of reprogrammed adult cells, called induced pluripotent stem cells, has proven to be pluripotent.
Explanation:
Answer:
anticodon sequence of three nucleotides on a tRNA molecule that bond to a complementary sequence on an mRNA molecule.
Answer:
Unlike most nonmammalian animals, scorpions are viviparous, giving birth to live young instead of laying eggs. Once fertilized, the eggs are retained in the female's body, where the embryos are nourished in utero for periods varying from several months to a year.
Explanation:
Answer:
Exponential Growth: y = a(1 + r)x
Exponential Decay: y = a(1 - r)x
Explanation:
Remember that the original exponential formula was y = abx.
You will notice that in these new growth and decay functions,
the b value (growth factor) has been replaced either by (1 + r) or by (1 - r).
The growth "rate" (r) is determined as b = 1 + r.
The decay "rate" (r) is determined as b = 1 - r
The ribosomes on the rough endoplasmic reticulum (RER) most likely produces neuronal special proteins.
Explanation:
Conduction of electrical impulses by action potentials of neurons takes place through controlled flow of charged ions through neuronal membranes. This ion transfer is controlled by specialized neuronal channel proteins which are present in the neuronal cell membrane.
These channel proteins allow for hydrophillic passage of ions and water molecules across the neuronal membranes.
Ribosomes that are attached to the RER are involved in protein synthesis. They carry the code for proteins carried by the mRNA and translate into respective protein.
The RER along with some free ribosomes cluster together as Nissl bodies and are mainly involved in neuronal specialized proteins.
