Answer:
Option (3).
Explanation:
The action potential may be defined as the change in the electric potential of the cell that helps in the propagation of the nerve impulse. The resting membrane potential of the cell is -70mV.
Threshold potential may be defined as the minimum potential required to transmit the nerve impulse. If the difference between the excitatory signal and inhibitory signal exceeds the minimum intensity, known as threshold. The propagation of nerve impulse occurs.
Thus, the correct answer is option (3).
Answer:
NORTH STAR AND THE LITTLE DIPPER
Finding the Big Dipper in the night sky is the easiest way to find Polaris, the North Star, located in the constellation Ursa Minor, the Little Bear. The Big Dipper rotates around the north celestial pole, and always points the way to the North Star
Explanation:
Answer:
The correct answer is true.
Explanation:
The biologist has proposed few characters on the basis of which a living organism can be distinguished from non-living things like cellular organization, reproduction, heredity material, metabolism, homeostasis, growth and development.
For a living organism to maintain their continuity on the planet has to reproduce via asexual or sexual means through which its genetic material can be passed on to its offspring.
Thus, true is the correct answer.
C. I think so, it seems like it
The correct answers are C. Amount of rainfall, and D. Wind speed.
Explanation
Radars are instruments that were created by humans to detect objects, people, places, among others, through signals. Radars are devices used in different fields such as war, aviation, climatology, geography, among others. One of the best known is the Doppler radar, which is a climatological tool that is used to detect the intensity, size, quantity, and direction of rainfall. Likewise, rainfall is influenced by the direction and speed of the wind, data that can also be obtained using this tool. One of the purposes for which this object was created was the early detection of natural phenomena related to rains, and winds such as hurricanes, electric storms, hail, among others. Therefore, the two objects that scientists can obtain with a radar are C. Amount of rainfall, and D. Wind speed.
