Answer:

All embryonic stem cells are undifferentiated cells that are unlike any specific adult cell.

Human embryonic stem cells are derived from in vitro fertilized embryos less than a week old

Embryonic stem cells are of great interest to medicine and science because of their ability to develop into virtually any other cell made by the human body.

Scientists have been attempting to isolate and culture human embryonic stem cells for more than a decade.

Human embryonic stem cells will offer insights into developmental events that cannot be studied directly in humans in utero or fully understood through the use of animal models

b. Georges Cuvier

c. Thomas Malthus

d. Charles Darwin

e. Charles Lyell

Lamarck published his theory of evolution in 1801, while Darwin published his book on “origin of species in 1859.  

The result predicted by Lamarck regarding impact of environment on evolution was further supported by Darwin, and future scientist.  

Hence, option A is correct

Where do preganglionic neurons synapse with postganglionic neurons in the sympathetic nervous system?.
FinnZ [79.3K]

Preganglionic axons synapse at the sympathetic chain ganglia with a postganglionic neuron. The postganglionic neuron then leaves the sympathetic chain ganglia through a gray ramus communicans (unmyelinated axons) and reenters the spinal nerve and travels to the skin and blood vessels throughout the body.
