Complete Question:
In the first paragraph, the words “disrobed,” “unveiling” and “deconstructed” primarily serve to (a) highlight the negative connotations that laser technology currently has, (b) emphasize the extensive reach of laser technology; (c) demonstrate the inherently unknowable characteristics of objects, even with laser technology; (d) implicitly compare lasers to other forms of technology
Answer:
(b) emphasize the extensive reach of laser technology;
Explanation:
The use of the word disrobed and deconstructed from the passage emphasizes the extensive reach of laser technology. Even without looking up the dictionary meaning of the two words, one can easily deduce that the passage is a pro-laser technology one.
- The passage presents the use of the laser technology in solar exploration.
- It also show its use by ecologists.

The receptor and effector that is involved in the following are:
{a} blinking of eyes in light spark – cerebral receptor and corneal reflex effector.
{b} withdrawal of hand on touching hot – spinal reflexes
<h3>What are receptors and effectors?</h3>
Receptors are the molecules present in the cell that mix with a specific substance and react for a specific function.
Effectors are the muscles or organs that are used in the motion, of an organ of the body.
Thus, the {a} blinking of eyes in light spark – cerebral receptor and corneal reflex effector.
{b} withdrawal of hand on touching hot – spinal reflexes.

Answer: Magnesium
Explanation:
Galvanic cell is a device which is used for the conversion of the chemical energy produces in a redox reaction into the electrical energy.
The standard reduction potential for magnesium and zinc are as follows:
![E^0_{[Mg^{2+}/Mg]}= -2.37V](https://tex.z-dn.net/?f=E%5E0_%7B%5BMg%5E%7B2%2B%7D%2FMg%5D%7D%3D%20-2.37V)
![E^0_{[Zn^{2+}/Zn]}=-0.76V](https://tex.z-dn.net/?f=E%5E0_%7B%5BZn%5E%7B2%2B%7D%2FZn%5D%7D%3D-0.76V)
Reduction takes place easily if the standard reduction potential is higher (positive) and oxidation takes place easily if the standard reduction potential is less (more negative).
Here Mg undergoes oxidation by loss of electrons, thus act as anode. Zinc undergoes reduction by gain of electrons and thus act as cathode.
Thus magnesium gets oxidized.
Explanation:
use the term electron sheilding, the more electrons between the valence el3ctron and nucleus the easier to lose the valence electron (more sheilding = easier to lose)
Density (p) is defined as the mass (m) per unit volume (v) or:
p = m/v
Using this relationship, the volume is:
v = m/p
Using the given values of mass of 80 grams and density of 8 g/cm3, the sample volume is:
v = 80 grams/8 grams/cm3
v = 10 cm3
The final answer is 10 cm3.
