Answer:

As the Earth moved out of ice ages over the past million years, the global temperature rose a total of 4 to 7 degrees Celsius over about 5,000 years. In the past century alone, the temperature has climbed 0.7 degrees Celsius, roughly ten times faster than the average rate of ice-age-recovery warming

Explanation:

and it just keeps going from here!

Binding of ________________ to receptors (ligand-gated) on the sarcolemma at the neuromuscular junction is vital for depolarizat

kifflom [539]

Answer:

Binding of ACh (acetylcholine) to receptors (ligand-gated) on the sarcolemma at the neuromuscular junction is vital for depolarization of the muscle fiber.

Explanation:

It allows acetylcholine to be released into this synapse when an action potential hits a neuromuscular junction. Acetylcholine attaches to the nicotinic receptors localized on the post-synaptic membrane of the muscle fibre's motor end plate, a specialized region.

Hence , the answer is ACh (acetylcholine) .

Nuclei with an _____________ number of protons and neutrons possess a property called spin. Nuclear spin can be thought as eithe

andriy [413]

Answer:

Explanation:

$\text{We are to fill in the blanks with the correct words that best suit the blanks}$

$\text{Nuclei with an} \ \mathbf{odd} \ \text{number of protons and neutrons possess a property }$

$\text{called spin. Nuclear spin can be thought as either up or down with the spin }$

$\mathbf{magnetic \ field.}$

$\text{When a molecule is placed in an NMR, a large} \ \mathbf{magnetic} \ \text{field is applied making the }$ $\text{spin states become of unequal energy, with the spin that generates a magnetic field }$ $\text{in the same direction of the applied magnetic field being}\ \mathbf{ lower} \ \text{ in energy. The NMR }$ $\text{then uses} \ \mathbf{ radio \ frequency}\ \text{ to 'flip the spin' of each nuclei, wherein each nuclei will }$ $\text{require a specific energy level of radiation that corresponds to its difference in }$ $\text{energy of spin states, this is often called the nuclei's}\ \ \mathbf{resonance } \ \text{frequency, }$ $\text{which is measured by the NMR and translated to teh final spectra.}$
