Given:
m = 12 g, the mass of the cylinder
r = 2 cm, the radius of the cylinder
h = 6 cm, the height of the cylinder.
Calculate the volume, V, of the cylinder.
V = πr²h
= π*(2 cm)²*(6 cm)
= 75.398 cm³
By definition,
density = mass/volume.
Therefore,
density = m/V
= (12 g)/(75.398 cm³)
= 0.159 g/cm³
= 0.16 g/cm³ (nearest hundredth)
Answer: 0.16 g/cm³
Answer:
to transmit an output in response to the total afferent input
Explanation:
An effector refers to parts of the body generates response. An effector responds to transmit an output in response to the total afferent input Stimulus in the body are detected by the receptor which send signals to the central nervous system via sensory neuron where interpretation and a response is coordinated by the brain. The response is sent to the effector through the motor neuron.
Answer No 1:
Phospholipids are made up of phosphorus head and two fatty acid molecules. These phosphorus head and fatty acid tail is joined together by glycerol. Fatty acid molecules are made up of Carbon, hydrogen and oxyge. Hence,carbon and hydrogen can be said as two other elements present in phospholipids.
Answer No 2:
The building blocks of lipids are glycerol and fatty acids.
Lipids can be described as vital organic molecules which are not soluble in water. They are made up of chains of carbon, hydrogen and oxygen. Someof the examples of lipids are fats and oils. Lipids are the main molecules present in an organisms cell membrane and hence have huge biological importance.
Answer No 3:
Lipids are biologically important molecules as they play very vital roles in the functioning of an organisms body. Two of the functions of lipids are:
- Lipids and phosphorus molecules combine to form phospholipids. The phospholipids are the main molecules out of which the cell membrane is made. Hence, lipids play an essential role in providing the cell membrane its structure.
- Lipids store energy and provide insulation to the body of an organism.
