Answer:
They used relative dating to divide Earth's past in several chunks of time when similar organisms were on Earth. Later, scientists used absolute dating to determine the actual number of years ago that events happened. The geologic time scale is divided into eons, eras, periods, and epochs.
Explanation:
Definitely true, because it is in a constricted space and you end up breathing more of it in, causing more harmful effects than if you were smoking the cigarette yourself
Answer:
-70 mV
Explanation:
Given that Neuron A and Neuron B interact with Neuron C
Neuron A produces ; - 2mV of IPSP and fires 6 times
Neuron B produces ; 3mV of EPSP and fires 4 times
Resting potential = - 70mV
threshold = - 50mV
The resulting membrane potential in neuron C
= -70 + 6(-2) + 4(3)
= -70 - 12 + 12 = -70 mV
Answer:
It will experience a low tide because water is drawn away from the area between the high tides.
Explanation:
The oceans on earth bulge outwards towards the sun and moon due to gravitational pull. This building is highest when the moon and sun are in line (same plane). The coastline within this plane will experience high tides while those at the right angle will have the lowest tides.
B.
H in HF is slightly positive while O in H2O is slightly negative. So they attract in a polar bond. Btw I thought this is chemistry.
