Answer: Option B,C, E and F
Explanation:
Action potential describe rise or fall of membrane potential of a particular cell location. This happen when neuron send impulses away from cell body. During action potential, one of the neural membrane opens so as to allow positively charged ions inside the cells and negatively charged ions to move outside the cell.
It draws a conclusion based on what would best explain one's observations.
Inference is the process where logical consequences evolve from premises that are assumed to be true. Knowledge backed with observations and reasoning as evidence is used to make conclusions. It is also referred to as an educated guess and is not necessarily factual.
Answer:
The correct answer is "It prevents spontaneous muscle's contraction".
Explanation:
Muscle contraction is produce by the interaction of actin and myosin filaments. Basically, myosin binds to the active sites of actin, which produces a protein complex (known as actomyosin) that allows that the filaments slide past each other and generate a contraction. When troponin and tropomyosin block the active sites of actin prevents spontaneous muscle's contraction, because a nervous impulse is needed to remove the inhibitors and that myosin starts the contraction.
Biomes are described in terms of abiotic factors like soil type and climate, and biotic factors factors like plant and animal life.
1. Latitude and the heat transported by winds are two factors that affect global climate.
2. Other factors, among them an areas proximity to an ocean or mountain range also influence climate.
Answer:
Bacteria that are oxidase-negative may be anaerobic, aerobic, or facultative; the oxidase negative result just means that these organisms do not have the cytochrome c oxidase that oxidizes the test reagent. They may respire using other oxidases in electron transport.)
