4. Large, circular lily pads are able to float on the water's surface.
Answer: cohesion
Cohesion mean that water attracted to another water. This force will make the water to form a surface tension in the lake. Water lily has a wide and thin leaf which makes it giving a low force per area. If the force applied on the surface is not bigger than surface tension, the leaf will stay float above the water. Surface tension also the reason water spider could walk on water.
5. The temperature of the water is about 5°C, while the temperature of the air is about 21°C.
Answer: heat capacity
Water has high heat capacity. High heat capacity mean that the water will not be easily become cold or hot. It will need more energy to increase/decrease the temperature of the water. This is why the water could keep its temperature much lower than the atmosphere. This will protect the organism inside the water from an extreme temperature change.
Question:
To code for the operating microscope, what verbiage are you looking for in the medical record?
(a)loupes were donned for magnification
(b)microdissection may be necessary
(c)due to the intricate dissection under magnification
(d)the operating microscope was steriley draped and brought into the surgical feild
<u>Answer</u>:
Option D: The operating microscope being sterilely draped and brought into the surgical field.
<u>Explanation:</u>
The loupe present is for the single vision magnifying glass, that can be frequently seen with the gold smith and with the watchmakers. The operating microscope are the binocular microscope through which small intricate parts can be observed during repairing of the watches etc. It is used in the surgery for observing the blood vessels as well as the nerves. This instrument can never be sterilized so after the use, it should be properly wrapped sterilely and kept inside the operation room.
