In the image above, the region labeled “ A “ is called the . . .
White matter
Dorsal Horn
Central Canal
Ventral Root
Answer:
Ans B)=====> Dorsal Horn
Two arms, each known as a Dorsal Horn, are formed by the core grey matter at the back of the spinal cord. In the image, the region labeled “ A “ is called the Dorsal Horn. Therefore, option B is correct.
What is dorsal horn ?One of the gray longitudinal columns discovered inside the spinal cord is the dorsal horn. Through the dorsal roots of the spinal nerves, it predominantly serves as the end of primary afferent fibers.
A complex network of excitatory and inhibitory interneurons, as well as projection neurons, make up the dorsal horn, which serves as an intermediary processing center for this information. It transmits the processed somatosensory information from the spinal cord to the brain.
The cell bodies of sensory neurons are located in the dorsal horns. The ventral horns are two arms of central grey matter that are found at the front of the spinal cord.
Thus, option B is correct.

What is the theoretical yield of carbon dioxide? 0. 993 g 2. 98 g 3. 65 g 8. 93 g.
Answer:
The answer is C.
Explanation:
i got a 100 on the test
The theoretical yield of carbon dioxide, CO₂ obtained from the reaction is 8.93 g
We'll begin by calculating the mass of citric acid, H₃C₆H₅O₇ that reacted and the mass of carbon dioxide, CO₂ produced from the balanced equation.
H₃C₆H₅O₇ + 3NaHCO₃ —> 3CO₂ + 3H₂O + Na₃C₆H₅O₇
Molar mass of H₃C₆H₅O₇ = (3×1) + (12×6) + (5×1) + (7×16) = 192 g/mol
Mass of H₃C₆H₅O₇ from the balanced equation = 1 × 192 = 192 g
Molar mass of CO₂ = 12 + (2 × 16) = 44 g/mol
Mass of CO₂ from the balanced equation = 3 × 44 = 132 g
From the balanced equation above,
192 g of H₃C₆H₅O₇ reacted to produce 132 g of CO₂
Finally, we shall determine the theoretical yield of CO₂. This can be obtained as follow:
From the balanced equation above,
192 g of H₃C₆H₅O₇ reacted to produce 132 g of CO₂.
Therefore,
13 g of H₃C₆H₅O₇ will react to produce = (13 × 132) / 192 = 8.93 g of CO₂.
Thus, the theoretical yield of CO₂ is 8.93 g

Apply the fertilizer.
Answer:
AbstractOrganic fertilizers are an essential source for plant nutrients and a soil conditioner in agriculture. Due to its sources and the composition of the organic inputs as well as the type, functionality and failures of the applied treatment process, the organic fertilizer may contain various amounts of infectious agents and toxic chemicals, especially the antibiotics that can be introduced to the subsequent food chain. A range of human and animal pathogens of bacterial, viral and parasitic origin have been the cause of food-borne epidemics due to unintended contamination from organic fertilizers. The use of antibiotics by humans and in animal feeds will also end up in the organic fertilizers. These antibiotics and other chemicals, depending on the sources of the organics, will enhance the likelihood of occurrence of resistant and multi-resistant strains of microorganisms in society and have been reported to cause ecotoxicological environmental effects and disruption of the ecological balance. Exposure of microorganisms to sublethal concentration of antibiotics in the organic products induces antibiotic resistance. WHO guidelines for the reuse of excreta and other organic matters identify the risk for the exposed groups to the reuse of the

A chemist has dissolved a certain substance in water. The chemist knows that more of the substance could be dissolved into the water before it stops dissolving. Therefore, the current solution is
.
Answer is: the current solution is unsaturated.
Unsaturated solution means that more of a substance can be dissolve.
For example:
Solubility of potassium chlorate (KClO₃) at 100 grams of water at 80°C is 37.5 g, that means that all 37.5 g is completely dissolves, this is the saturated solution.
If we add 20 grams of potassium chlorate in 100 grams of water, there is less solute than the saturated solution, so this is unsaturated solution.

Excited hydrogen atoms emit light in the ultraviolet at 2.47x1015Hz. What is the
energy of a single photon with this frequency?
The energy of a single photon of this frequency is 1.638 × 10⁻¹⁸ J
Using Planck's equation, the energy of the photon E = hf where h = Planck's constant = 6.63 × 10⁻³⁴ Js and f = frequency of ultraviolet light = 2.47 × 10⁻¹⁵ Hz.
Substituting the values of the variables into the equation, we have
E = hf
E = 6.63 × 10⁻³⁴ Js × 2.47 × 10¹⁵ Hz.
E = 16.3761 × 10⁻¹⁹ J
E = 1.63761 × 10⁻¹⁸ J
E ≅ 1.638 × 10⁻¹⁸ J
So, the energy of a single photon of this frequency is 1.638 × 10⁻¹⁸ J

When reactants are not used to make new substances, are they destroyed?
In a chemical reaction, only the atoms present in the reactants can end up in the products. No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

How do catalysts generally affect chemical reactions? A They increase the temperature of the system. B They increase the surface area of the reactants. C They increase the activation energy by introducing enzymes. D They lower the activation energy by providing an alternate pathway.
Answer:
D
Explanation:
A catalyst is a substance that increases the rate of a chemical reaction by lowering the activation energy without itself being consumed by the reaction.
Activation energy is the minimum amount of energy required for a chemical reaction to proceed in the forward direction.
A catalyst increases the reaction rate by providing an alternative pathway or mechanism for the reaction

Answer:
In chemistry, the law of conservation of mass states that the mass of the products (the chemical substances created by a chemical reaction) will always equal the mass of the reactants (the substances that make the chemical reaction). Think of it as being similar to balancing an algebraic equation.
Explanation:
