Merkel receptor – disk shaped, close to surface, slow adapting, small
receptive field, respond best to PRESSURE and TEXTURE.
(2) Meissner corpuscle – stack of flattened cells with nerve fiber
weaving through, close to surface, rapidly adapting, small reception
force, respond best to LIGHT TOUCH, such as tapping or fluttering.
(3) Ruffini cylinder – many branched fibers in cigar shaped capsule,
deep in dermis, slow adapting, large reception force, respond best to
STRETCHING and play important role in kinesthetic sense.
(4) Pacinian corpuscle – layered, onion-like, deep in dermis, fast
adapting, large reception force, respond best to DEEP PRESSURE touch and
high frequency VIBRATION.

Answer:
it shows the breakdown of the atom
Explanation:
it will show it molecularly
Answer: either B, or D
Explanation:
because one of those are the answer
Answer:
108.3g
Explanation:
Given parameters:
Volume of solution = 570mm = 0.57L (1000mm = 1L)
Molarity of solution = 2M
Unknown
Mass of MgCl₂
Solution
We first find the number of moles in the given concentration of magnessium chloride using the expression below:
Number of moles of MgCl₂= Molarity x volume = 2 x 0.57 = 1.14moles
Using this known moles, we can the unknown mass of MgCl₂ the technician would require:
Mass of MgCl₂ required = number of moles of MgCl₂ x molar mass
Molar mass of MgCl₂:
Atomic mass of Cl = 35.5g
Atomic mass of Mg = 24g
MgCl₂ = 24 + (35.5x2) = 95gmol⁻¹
Mass of MgCl₂ required = 1.14mole x 95gmole⁻¹ = 108.3g
