Answer:
Tissue
Explanation:
A cell is a structure formed during the evolution which contained all the molecules and favourable conditions required to survive and therefore acts as the functional and structural unit of life.
In evolution, more than one cell aggregated together to form a structure which could perform much complex function than a single cell called tissue as they are programmed to perform the same function.
In the given question, since the heart cells worked together to cause movement in the robot therefore the cardiac cells formed cardiac tissue or heart.
Thus, the tissue is the correct answer.
Answer: Closed
Explanation:
At resting membrane potential( RMP) sodium channels remained shut, this is because , previously in depolarisation,the voltage gated sodium channels were opened for sodium to diffuse into the Axon. However these channels closed after reaching their refractory period,s.
Therefore a change in the extracellular concentration of sodium will not open them
Weathering of rocks and soil is the primary way that clays and clayminerals form at the Earth's surface today. ... Factors governing rockweathering and soil formation include the initial type of rock, the ratio of water to rock, the temperature, the presence of organisms and organic material, and the amount of time
