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:
weighing balance/analytical balance
Graduated cylinder/buret
Explanation:
The mass of the evaporating basin could be measured using a weighing balance or an analytical balance. Both are classified as weighing scales but the analytical balance can measure the mass of objects up to 4 decimal places, thus, providing better accuracy in measurement than ordinary weighing balance that can only measure up to 2 decimal places.
In order to measure 50 cm3 of the sea water, a graduated cylinder or a buret can be used. Both equipment can measure up to the same decimal places and, thus, have virtually the same accuracy.

Radiation is the heat that travels directly to the earth
A bimolecular reaction can be kinetically first order in behaviour provided one of the reactants is taken in such a large excess that its concentration may hardly change. Such a reactant will not contribute to the order. Thus, a bimolecular reaction will be of first order. These reactions are known as pseudo chemical reactions.
