Answer: Amalgam Condenser
Explanation:
The instruments used for an amalgam restoration are:
- Tofflemire Matrix
-Wedges
-Amalgam Carrier
-Amalgam Well
-Amalgam Condenser (Small & Large)
-Liner Applicator
-Excavator
-Enamel Hatchet
-Discoid-Cleoid Carver
-Walls Carver
-Interproximal Scaler
However, to cover shape the amalgam the instrument used is Amalgam Condenser. That is used for packing/covering the amalgam into the cavity. The process must be at least 1.5mm deep in order to restore amalgam
The correct answer is:
C. Four food groups
Answer:
At first, a fetus cannot distinguish between different voices.
A fetus begins responding to sound at between 22 and 24 weeks but can only hear low frequencies, such as a dog barking or a lawn mower.
As the auditory system and the brain continue to develop, this range increases. By late pregnancy, the fetus can hear voices and distinguish between
so at 22 weeks they're in the middle of the second trimester and can hear sounds but in the 3rd trimester can distinguish between voices
<span>1. Density is the mass of a substance divided by its volume. D= m/v
2.
To measure the volume of an irregular object you can fill a container with water and submerge the item. You would then measure the volume of water that was displaced by the obect.
3. D = m/v so m = 10.00 grams and v = 15.625 cm3
D= 10.00 grams/15.625 cm3 = 0.64 g/cm3</span>
Answer:Chemo receptors
Explanation:
Chemo receptors/ Chemo-sensors are specialized nerve cells sensors that detect changes in certain types of chemicals le CO2, O2, and pH, and respond accordingly based upon location of the stimuli, and can be Direct or Indirect.
In the direct case, the chemo receptors, found in the carotid body located at the carotid artery monitors and detects levels of pH in the cerebrospinal fluid, oxygen and carbon dioxide in the blood and helps in breathing, the rate and depth of of breathing according to a person's needs that is why it is very difficult for one to suffocate by holding their breath because these nerve cells will trigger back to the respiratory centers, an involuntary breathing response due to the critical signals of chemicals they detect in the blood.
Indirect chemo receptors can be found in the nose and tongue for detecting smell and taste.
