The difference between the two is that a virus can replicate itself by attaching to another file or program and becoming part of that program and it spreads from one computer to another leaving infections whereas a worm ca replicate itself independently. Worms are standalone software and do not require a host program or human being help to propagate, it enters a computer through a vulnerability in the system and takes advantage of file-transport or information travel.
After it is released from the ovary, an egg lives for A. 1 day.
This is a part of a larger process that spans longer periods of time.
Answer:
e. All of the choices describe characteristics of the ANS.
Explanation:
The autonomic nervous system is a regulatory and control system that influences the functions of internal organs.
Autonomic pathways consist of two types of motor neurons, these are the preganglionic neuron and the postganglionic neuron.
ANS stimulation of involuntary effectors is always excitatory. In the preganglionic autonomic neurons, and all postganglionic parasympathetic neurons are usually (cholinergic i.e receptors that bins with acetylcholine), as a result they release acetylcholine as a neurotransmitter. The cholinergic effects of preganglionic autonomic neurons are always excitatory.
The postganglionic neuron lies entirely in the peripheral nervous system.Yes!, this is so because the ganglion cells that give rise to postganglionic axons lies through the gray rami communicans and join the peripheral nerves of the peripheral nervous system.
"Biological diversity<span>" means the variability among living organisms from all sources including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part: this includes diversity within species, between species and of ecosystems.</span>
