Answer:

b. The red and green inks will be uniformly distributed throughout the pan.

Explanation:

The inks distribute throughout the particles of water. It does not matter that one drop of ink was placed in one end, and the other on the other end. The constant movement and collision of particles make the ink's drop distribute uniformly in the pan. Besides, there will we a tendency to have the same amount of ink concentration in all the pan;  to this, they have to distribute evenly.

According to the theory of plate tectonics, which is one feature that plates carry?
Phoenix [80]

Answer:

seafloor

Explanation:

  • A plate, often described as a lithospheric plate, with seafloor, continents and mountains on top of it.
  • The earth is divided into three layers based on their chemical composition. Undoubtedly, there is a component called the lithosphere.
  • The lithosphere consists of a crust and a portion of a solid upper mantle.
  • Below the lithosphere is the asthenosphere.
  • There are two types of crusts: the continental crust and the oceanic crust.
  • Where there is a seabed there is a sea crust.
  • Mountains are also found in oceanic and continental crusts.
  • The intercontinental layer corresponds to the continents.

emmainna [20.7K]

Answer:

A. Total Vit D intake = 1150000212 IU

B. Yes he met his RDA and does not need any supplements

C. 191666702%

Explanation:

I μg = 40 IU

1 oz = 28.35 g

I g = 1000000 μg

A. Low-fat Yoplait yogurt-2 μg = 2 * 40 IU = 80 IU

Cheerios cereal-1 μg = 40 1U

Coffee with milk-07μg = 0.7 * 40 = 28 IU

Turkey sandwich on whole-wheat bread with large garden salad-0.4 g = 0.4 * 1000000 * 40 IU = 16000000 IU Grilledd pork chop. 8 oz = 28.35 * 1000000 * 40 = 1134000000 IU

mashed potato and a side of gnled mixed vegetables-1.6 μg = 1.6 * 40 = 64 IU

Total vitamin D intake = 1150000212 IU of Vit D.

B. Since his RDA is 600 IU, he met his RDA and does not need any supplements of Vit D.

C. Percentage of his RDA Vit D intake = (1150000212/600) * 100% = 191666702 %

An undersupply of the major inhibitory neurotransmitter known as ________ is linked to seizures.
bazaltina [42]

Answer:

Gamma-aminobutyric acid (GABA)

Explanation:

Epileptic seizures are induced by a preponderance of electrical activity within the network of neurons in the brain. Synapsis is the meeting point between the axon of one neuron and the dendrite of another neuron. Electrical signals don't cross through the synapsis, instead, they are conveyed in a chemical form by neurotransmitters.

The neurotransmitters convey messages across the synapsis in a chemical form until they find to the receptor of the dendrite of the receiving neuron. Neurotransmitters can either be excitatory or inhibitory in function i.e. the receiving neuron can either be stimulated to action or inhibited from action. The main excitatory and inhibitory neurotransmitters in the brain are Glutamate and Gamma-aminobutyric acid (GABA) respectively.

There must be a balance between excitation and inhibition of neurons, in order to ascertain the optimal functioning of the brain. Too much Glutamate or too little of GABA can make neurons hyperexcitable and hyperexcitability of neurons makes the brain susceptible to seizures.
