The conclusion that coral does not grow well in conditions with high salt is invalid because (B) The experiment changes more than one variable at once.
In order to correctly study the effect of three variables on there needs to be, 3 x 3 x 3 = 27 different aquariums (every variable takes 3 different values and there are 3 different variables).
In these aquariums, only one condition needs to be varied at a time to study its effect. To study the condition with high salt, the temperature and pH needs needs to be kept fixed at a particular value whilst varying the salinity from normal to low to high.
Answer:
Nitrogen-Oxide, and Nitric-Oxide
Explanation:
Google said so.
The first to observe and describe cells, by noting that the cells in a wine cork resembles the living quarters of monks or prisoners was <span>Scientist Hooke he
was once in jail and that may have been one of the reasons he made the
connection to the cells shape and called them what they are today.</span>
Synapse
It carries information through electrical impulses to the cell body.
It is the gap between neurons.
It ensures that information travels in one direction only.
Explanation:
A synapse is the gap or the junction where two or more neurons or nerve cells meet together.
Also called the synaptic cleft, the synaptic gap receives the electrical signals and passes them through one nerve cell to another
The axon nerve endings release neurotransmitters which ensure that the path of transmission of impulses is only unidirectional – only from presynaptic to postsynaptic path.
The synaptic gap between a nerve cell and an effector muscle cell is referred as the neuromuscular junction.
