Answer: C. Between deoxyribose sugar and phosphate group in a DNA nucleotide.
Explanation:
Hydrogen is a very important element in the planet due to the many uses of its compounds for example, water. Hydrogen is also very important to humans as it is integral to DNA formation.
Hydrogen bonds exist in the DNA nucleotide to ensure that different strands are connected to each other. These strands are composed of bonds between deoxyribose sugar and phosphate groups.
Answer:
The jelly is able to hold the weight of gravity
Explanation:
In neuroscience, the threshold potential is the critical level to which a membrane potential must be depolarized to initiate an action potential. Threshold potentials are necessary to regulate and propagate signaling in both the central nervous system (CNS) and the peripheral nervous system (PNS).
Most often, the threshold potential is a membrane potential value between –50 and –55 mV,[1] but can vary based upon several factors. A neuron's resting membrane potential (–70 mV) can be altered to either increase or decrease likelihood of reaching threshold via sodium and potassium ions. An influx of sodium into the cell through open, voltage-gated sodium channels can depolarize the membrane past threshold and thus excite it while an efflux of potassium or influx of chloride can hyperpolarize the cell and thus inhibit threshold from being reached.
We sprinkle powder on carrom board to make the surface of the board smooth. This reduces the friction between the surface of the carrom board, the striker and the coins. As a result, the coins and the striker can move easily on the carrom board.
