Hi! Do you still need help?
Kroto, Smalley and Curl are scientists who were able to deduced the shape of carbon -60 with molecular models. During the experimentation, they used HIGH POWER LASER ENERGY to heat carbon to star-hot temperature.
Answer:
Pass information by generating electric signals
Explanation:
Neurons are the fundamental unit of the nervous system. Neurons send information across the body through generation of electric signals called as action potential. There are basically three types of neurons
a) Sensory neurons which carry information from the sense organs in the form of impulse to the central nervous system (CNS)
b) Motor neurons – These carry information from the CNS to the body parts such as sense organs, muscles etc.
c) Interneurons – They are connecting neurons which are responsible for transferring information from one neuron to the other neuron.
Answer:
The answer is D. Prokaryotes have one origin of replication but it proceeds in two directions.
Explanation:
DNA replication is a process in which in which one parental DNA strand acts as template to synthesize complementary daughter strand. There are specific sequences in DNA from where replication starts. These sequences are called origin of replication. In Eukaryotic cells due to large number of DNA many origins of replication are present. However, in prokaryotic DNA only one origin of replication is present that is bi-directional.
