Answer:
A warm cup of coffee is an evidence of relation between the touch of an object and one’s perception.
Explanation:
According to the scientific study performed by the researchers of Yale- John Bargh, Christopher Nocera and Joshua Ackerman, the direct relation of objects with ones touch and one’s perception about a person is proven.
An experiment to rate a person’s personality by a group of people was organised, where they were given both cold and hot coffee during the session. It has been seen that the persons who were having warm coffee gave positive ratings to that person rather than the people having icy coffee.
This proves that a warm touching object can influence the warm feeling in a person.

Sentences:
#1 A Hammerhead shark is a type of shark that comes from the family, Sphyrnidae. These sharks were named for their head shape, <span>which are flattened and laterally extended into a "hammer" shape.
#2 The Wobbegong shark is known as a type of carpet shark and is </span>found mostly in the shallow temperate and tropical waters of the western Pacific Ocean. As well as in the Eastern Indian Ocean.
#3 Sand Sharks come from the Odontaspididae family. These sharks can be found world wide, and mostly in tropical waters. It can also be known as the Sand Tiger Shark in both the US and in the UK.<span>
#4 The Sawshark has a l</span><span>ong, saw-like rostrum edged with sharp teeth. They use this to slash and disable their prey.
#5 An Angelshark contains a flattened body and wide </span><span>pectoral fins, that offten give them a strong resemblance to rays.
#6 The Cat shark can also be refered to as the Bamboo shark. This species finds comfort in swing very close to the ground.
#7 Cow Sharks belong in the </span><span>Hexanchidae family because of their additional pair of gill sets.
#8 The Bramble shark can be found in the </span><span>eastern Pacific Ocean, and in tropical and temperate waters worldwide.
#9 A Carpet shark can commonly be mistaken for a Wobbegong shark, although they can sometimes be the length of a whale shark.
#10 The Alopias shark can also be known as a Thresher shark and has the ability to</span> <span>inhabit both coastal waters and oceans far from land, from the surface to depths of at least 360 meters.
#11 The </span><span>Carcharhiniformes shark can also be known as a ground shark and they can weigh as much as a Bull shark.
#12 The Heterodontus is a bull shark </span><span>that is a small order of basal modern sharks. </span><span>
#13 </span>Sharks in the Swualiformes family, have two dorsal fins, which usually possess spines.
#14 The <span>Hexanchiform shark has only one dorsal fin and six or seven gill slits. This species is extinct.

Sorry this took me so long to complete. It was a lot!!
Hope this helps!!</span>
Answer:
The diagram is attached below.
Explanation:
when sodium and chlorine comes close together they form anion and cation. The compound formed is called sodium chloride.
Both atoms bonded together through ionic bond.
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.
For example:
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion.
Answer:
The Lipid Bilayer
Explanation:
The lipid bilayer has been firmly established as the universal basis for cell-membrane structure. It is easily seen by electron microscopy, although specialized techniques, such as x-ray diffraction and freeze-fracture electron microscopy, are needed to reveal the details of its organization. The bilayer structure is attributable to the special properties of the lipid molecules, which cause them to assemble spontaneously into bilayers even under simple artificial conditions.
