Answer: Micro villi
Explanation:
The cellular structures that increases the superficial surface area of the cell is known as micro villi. It is an extension of cell membrane.
This structure helps in the increasing the surface area for the maximizing the absorption of food materials.
It also helps in providing a large area in a very compacted space. It is found at many places in the human body such as in small intestine.
Answer:
Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.It can be decomposed into simpler constituents using chemical reactions. Example: water 
Physical property is defined as the property of a substance which becomes evident during physical changes. Water is liquid at room temperature whereas hydrogen and oxygen are gases at room temperature.
Chemical property is defined as the property of a substance which becomes evident during chemical changes. Water reacts with metals to form bases, hydrogen reacts with metals to form hydrides and oxygen reacts with metals to form oxides.
A) TAGGATCTTCCA
b)GCAACGTCTTGA
c)ATGCCTAGCAGT
Potassium has the greatest influence on the resting membrane potential. Resting membrane potential is caused by the differences in the concentrations of ions inside and outside the cell. At resting membrane potential there are more sodium ions outside the neuron and more potassium ions inside the neuron. For a neuron the resting membrane potential is about -70 mV.
