Answer:

[OH-] = 1.08x10^-11 M

Explanation:

From the question given,

Concentration of Hydrogen ion, [H+]

= 9.3x10^-4 M

Concentration of Hydroxide ion, [OH-] =..?

The concentration of the hydrogen ion, [H+] and hydroxide ion, [OH-] are related with the following formula:

[H+] x [OH-] = 1x10^-14

Using the above formula, we can easily calculate the concentration of the hydroxide ion, [OH-] as follow:

[H+] x [OH-] = 1x10^-14

[H+] = 9.3x10^-4 M

9.3x10^-4 x [OH-] = 1x10^-14

Divide both side by 9.3x10^-4

[OH-] = 1x10^-14 /9.3x10^-4

[OH-] = 1.08x10^-11 M

Orlov [11]

The best description of the process to draw the segment is B. b place a compass at one endpoint of the segment and trace an arc. do the same from the other endpoint. draw a line through the intersections of the arcs.

<h3>What is a segment bisector?</h3>

It should be noted that a segment bisector simply means a line to segment which cuts another line segment at the center but dividing the lines into two equal halves.

In this case, based on the information given, the best description of the process to draw the segment is to place a compass at one endpoint of the segment and trace an arc, do the same from the other endpoint. draw a line through the intersections of the arcs.

In conclusion, the correct option is B.

For the leopard seals to survives this harsh environment, it must have a thicker layer of blubber

Blubber is a thick layer of fat. It is called the adipose tissues and found in most marine organisms.

  • This layer helps in insulating the body against heat loss.
  • By so doing, the animal is able to conserve internal heat.
  • They have low thermal conductivity and do not easily lose heat or gain heat as such.
