Two technicians were discussing hybrid organic acid technology​ (HOAT) coolants. Technician A stated that hybrid organic acid te

chnology​ (HOAT) coolants use organic acid salts​ (carboxylates) that are abrasive to water pumps. Technician B stated that the pH of hybrid organic acid technology​ (HOAT) coolants is usually below 7. Which of the following about the scenario is​ true?
A. Only technician​ A's assessment is accurate.
B. Neither technician​ A's nor​ B's assessment is accurate.
C. Both technician​ A's and​ B's assessments are accurate.
D. Only technician​ B's assessment is accurate.

Answer:

B. Neither technician​ A's nor​ B's assessment is accurate.

Explanation:

Technician A is wrong because HOAT use organic acid with a low silicate inorganic corrosion inhibitors and it doesn't damage water pump as it contains azole additive which is a copper corrosion inhibitor.

Technician B is wrong because all coolants operate at neutral or basic pH range (pH equal to or greater than 7).

When ten or more pre-synaptic neurons conduct impulses to five or fewer post-synaptic neurons, the conduction pattern is said to
lesantik [10]

When ten or more pre-synaptic neurons conduct impulses to five or fewer post-synaptic neurons, the conduction pattern is said to be <u>convergent</u>.

A neuron in such a network can take information from numerous other neurons through convergence. Inhibitory interneurons are activated by presynaptic cells, but instead they reduce nearby cells inside the network.

Synaptic divergence refers to the dispersion of synapses from such a single neuron onto several postsynaptic partners as well as partner kinds, while synaptic convergence refers to being affected by having neuronal cell kinds delivering input around on a shared postsynaptic partner.

Multiple presynaptic cells send convergent information to a single postsynaptic neuron.

Explain how both the digestive system and the urinary system work to conserve water in the human body.
Ghella [55]
Everything that we eat and drink contains some percentage of water. So, to start, you have to know that the human body has receptors which estimate if we have enough water in our blood and cells in general. From these receptors, the information travels through the neurons to the part of the brain that is responsible for activation of different responses. 

The digestive system is important because in its lower parts, liquids are absorbed and inserted in the bloodstream. Then through the bloodstream, they travel to all parts of the body and are absorbed by cells as needed. When blood passes through the body, it gets to the kidneys where water and electrolytes are filtered, reabsorbed if needed and excreted through the urine. 

Now, if the brain has a signal that the body has a lack of liquids, it activates hormones which influence the bloodstream in both the digestive and the urinary system. In this case, the digestive system will absorb more liquids from food because the hormones will make the blood vessels in the digestive area larger, and on the other hand, we will produce less urine because the kidneys will get an assignment from the brain to filter liquids, but to reabsorb them again as much as possible.

Which of the following is TRUE about this reaction?
hoa [83]

The right answer is C

This process is called anaerobic respiration. It doesn't need dioxygen to occur (it can happen with or without O2).

Anaerobic respiration is a mechanism in which electrons pass through a chain of transporters whose final acceptor is a mineral substance other than oxygen, unlike aerobic respiration where the final acceptor is dioxygen. The final acceptor may be the nitrate ion (as in the case of Pseudomonas), carbon dioxyde or the sulfate ion.

Some bacteria (Pseudomonas) are able, anaerobically, to reduce nitrates to nitrites and then, depending on the case, to dinitrogen (with the enzyme Nitrate reductase A).

NO3- ==> NO2- ==> N2.

When your cells use fat for energy, the fatty acids are broken up into molecules of acetyl COA. Predict how many ATP can be made
IgorC [24]

Answer:

12 molecules of ATP can be made from one molecule of acetyl CoA.

Explanation:

If one molecule of acetyl CoA enter TCA cycle then it result in the formation of 3 molecules of NADH,1 molecule of FADH2 and 1 molecule of GTP that is equivalent to 1 molecule of ATP.

                        Now the reducing equivalent such as NADH and FADH2 enters electron transport chain and get oxidized to regenerate NAD+ and FAD along with ATP. 1 molecule of NADH produces 3 molecules of ATP whereas 1 molecule of FADH2 produces 2 molecules of ATP.

               So that net gain of ATP is given below

3 molecules of NADH = 9 molecules of ATP

1 molecule of FADH2 =2 molecules of ATP

1 molecule of GTP = 1 molecule of ATP

As a result total 12 molecules of ATP is by the oxidation of 1 Acetyl CoA  by TCA cycle .
