Answer: True
Explosions due to electricity occurs due the passage of electrical current into air, this results in the transfer of energy from electricity to air. Electrical energy being a stimuli activates the molecules of air which leads to explosion. An explosion is a rapid event which involves release of energy in the form of gases and also destruction of surrounding entities. For explosion suitable fuel and combustion gases are required. Methane and natural gases acts as fuels whereas oxygen which facilitates combustion of these fuels.
Longest: D. Shortest: A. Strongest: A. Weakest: D.
Explanation: Answer choice A is the shortest and strongest. The greater number of bonds causes the electrons to be more compact and closer together. This makes the bond length short. Because the bond is tighter, it is also stronger.
Single bonds are the weakest and longest. So, now we must look at the difference between C and D. They're both C-C bonds, but the carbon bond in choice D is weaker because of the difference in p-character (hybridization).
The more medial is the tracheal bifurcation.
In anatomy, we refer that structure is more medial than other when it's closer to the median plane which is in the midline of the body, that divides the body into left and right. The <span>trachea its "crossed" by that imaginary line, while both lungs are more to the sides.</span>
Answer:
Explanation:
because a proton gradient is necessary over the inner mitochondrial membrane during oxidative phosphorylation for ATP production, ATP production will decease if gramicidin is added because the inner mitochondrial membrane will become permeable and the protons will be able to move in and out, there will be no electrochemical gradient left to drive ATP production. Electron transport will not be altered because it is dependent on the availability of NADH and FADH2. proton pumping also will remain the same but it will be useless because the protons can go back and forth
Answer:
false
Explanation:
The parathyroid gland refers to the four small endocrine glands located in the neck region behind the thyroid. It secretes the parathyroid hormone or parathormone which regulates the calcium levels in our bodies. It comprises two types of cells which are:
a. The oxyphil cells appear at the onset of puberty and they have no known functions. They appear pink or orange when stained with hematoxylin and eosin stain.
b. The chief cells are more abundant compared to the oxyphil cells and stain dark purple by the action of hematoxylin and eosin stain. Their major function is to produce parathyroid hormone which regulates the amount of calcium in the body.
