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: A
Explanation: the change in seasons is caused by Earths axis tilt and revolution and position near the sun
Answer:
Schwann cells or neurilemma cells are the cells which form the myelin sheath around neuronal axons in the peripheral nervous system (PNS) only.
Neurilemma is the collective term used for cytoplasm and nuclei present around the myelin sheath which helps in the regeneration process of nerves.
A Schwann cell surrounds the axon, invaginate it and the plasmalemma of the Schwann cells joins and from a double membrane structure called mesaxon. This mesaxon starts wrapping the axon in spiral fashion and cytoplasm start condensing into the compact myelin sheath.
Answer:
Deoxyribonucleic acid (DNA) hold the hereditary material that acts as a blueprint for the development and functioning of life process on the earth. It is a blueprint for every cell in every organism.
Its major function is to encode the DNA sequence of amino acid by using the triplet genetic code that code for a specific protein that perform a specific function in the body that are necessary for the normal function of the life processes.
