The water would be warmer 200 miles north of the equator than it would be 2000 north of the equator, because the closer you are to the equator the more sun light you get.
An Asian clam, a fresh water creature, is usually less than 50 millimeters.
It tends to be small and light-colored, with a shell ornamented by distinct, concentric sulcations, anterior and posterior lateral teeth with numerous fine serrations. It resides in brackish to freshwater rivers, lakes, streams, canals and reservoirs. This creature lies on or is slightly buried in materials such as sand, silt, or gravel-bottomed places. It usually prefers running water with high oxygen levels and has no tolerance for polluted or near-freezing water.
The evolution of the two species are very closely related but not identical
Answer:
Y is probably excitatory and Z is probably inhibitory
Explanation:
- Two neurons communicate with each other generally by releasing neurotransmitters.
- The neuron which releases the neurotransmitter is termed as presynaptic neuron and the neuron to which the neurotransmitter binds to exert its effects is called as postsynaptic neuron.
- Based on the nature of the neurotransmitter released, the presynaptic neurons can either be inhibitory or excitatory in nature.
- The change in the membrane potential of the postsynaptic neurons depends on the total sum of inputs coming from different pre synaptic neurons at a given time.
- From the given situation, the stimulation by X alone is causing deploarization of 0.5 mV which shows that it is causing excitation, and since depolarization is increasing when X and Y are stimulaneously stimulated Y is also excitatory in nature. However the depolarisation is not occurring when X and Z are stimualted together and hence, Z is probably inhibitory in nature.
