What is Milkshake

Milkshake is a cold beverage which is made from milk, ice cream or iced milk and also it got flavourings or sweeteners like fruit syrup or chocolate sauce. Milkshakes usually served in tall glasses with straw and whipped cream can be added as a topping. There are several popular milkshake flavours like vanilla, chocolate and strawberry. In the United States, milkshakes are made without ice-cream. If there are milkshake made with ice-cream it’s commonly called a frappe. Full-service restaurants usually prepare and mix the shake by hand from scoops of ice-cream and milk in a blender or drink mixer using a stainless steel cup. Most fast food outlets do not make shakes by hand with ice-cream. Instead they make shakes in an automatic milkshake machines which freeze and serve a premade milkshake mixture consisting of milk, sweetened flavouring agent and thickening agent.
Hand-blended milkshakes can be made from any flavour of ice-cream and can add flavourings like chocolate syrup and malt can be added prior to mixing. This allows greater variety compare to the variety that available in milkshakes machine. A milkshake-like recipes which use yogurt, crushed ice and fresh fruit which all are made without ice-cream usually called smoothies. When malted milk is added, a milkshake will be called a malted milkshake or malt.
The restaurant has the highest volume of customer that is coming so they often use pre-made milkshake mixtures that are prepared in automatic milkshake machines. The machines are stainless steel cylinder with beaters that use refrigeration coils to freeze pre-made milkshake mixture into a drinkable texture. The number of different flavours that a restaurant with automatic milkshake machines can serve is limited by the number of different tanks in their milkshake machines and usually fast food restaurant only offer several type of flavour for the milkshakes.

Honey Badger

The honey badger is a member of the Mustelidae family. The honey badger is distributed throughout most of Africa and western and south Asian areas of Baluchistan, southern Iraq, Pakistan and Rajasthan. It is the only species in the genus Mellivora and the subfamily Mellivorinae. The badgers have been named the most fearless animal in the Guinness Book of World Records. The under parts, sides of its body and face are usually dark brown or black in colour, while the top of its head, neck and back are light gray or white. This coloration makes the honey badger particularly conspicuous in daylight. Some honey badgers, especially in the Ituri Forest of the Democratic Republic of Congo, are wholly black.
Honey badgers are similar in size and build to the European badger, Meles meles. They are heavily built, with a broad head, small eyes, virtually no external ears, and a relatively blunt snout. The head and body length ranges from 60 to 102 cm, plus a tail of 16 to 30 cm. The animal height at the shoulder can be from 23 to 30 cm. Males sometimes weight twice as much as females. The weight range for female is 5 to 10 kg, while males range from 9 to 14 kg. Their small size can be deceiving to many would be predators. There have been numerous accounts where lions, tiger and bears have been killed when trying to eat a honey badger.
The honey badger can be found in grasslands and savannahs. Honey badgers are fierce carnivores with a keen sense of smell. They are known for their snake-killing abilities, they use their jaws to grab a snake behind its head and kill it. Honey badgers can devour a snake in less than 15 minutes. Badgers have a large appetite for beehives. Commercial honey producers do not take kindly to this destruction and sometimes shoot, trap, or poison badgers they suspect of damaging their hives, although badger-proof commercial bee hives have been developed.
A bird, the honey guide, has a habit of leading badgers and other large mammals to bee’s nests. When a badger breaks into the nest, the birds take their share. Honey badger is among the fiercest hunter in its range, with prey including earthworms, insects, scorpion, porcupines, hares, ground squirrels, meerkats, mongooses, and larger prey such as tortoises, young crocodiles, young gazelle and snakes. They also take lizards, frogs small rodents, birds and fruit. The badger’s ferocious reputation reflects its tendency to attack animals larger than itself, it is a seldom preyed upon.
Adult honey badgers rarely serve as prey for pythons, wolves, bears, lions, tiger and leopards, their ferocity and thick, loose skin makes it difficult to grip or suffocate them. It is able to twist inside its own skin and bite whatever is holding it.

What Is Forest

A forest can also be called a wood, woodland, wold, weald or holt is an area with a high density of trees. There are many definitions of a forest, based on the various criteria. These plant communities cover approximately 9.4% of the Earth’s surface or 30% of total land area, though they once covered much more about 50% of the total land area, in many different regions and function as habitats for organisms, hydrologic flow modulators, and soil conservers, constituting one of the most important aspects of the Earth’s biosphere. Although a forest is classified primarily by trees a forest ecosystemis defined intrinsically with additional species such as fungi. Woodland with more open space between trees is ecologically distinct from a forest.
Forest can be found in all regions capable of sustaining tree growth, at altitudes up to the tree line, except where natural fire frequency or other disturbance is too high, or where the environment has been altered by human activity. Forest sometimes contains many tree species within a small area as in tropical rain and temperate deciduous forests, or relatively few species over large areas. Forest often home to animal and plant species, and biomass per unit area is high compared to other vegetation communities. Much of this biomass occurs below ground in the root systems and as partially decomposed plant detritus. The woody component of a forest contains lignin, which is relatively slow to decompose compared with other organic materials such as cellulose or carbohydrate.
Forest are differentiated from woodlands by the extent of canopy coverage in a forest, the branches and the foliage of separate trees often meet or interlock, although there can be gaps of varying sizes within an area referred to as forest. A woodland has a more continuously open canopy, with trees spaced further apart, which allows more sunlight to penetrate to the ground between them.

Diamond

In mineralogy, diamond is an allotrope of carbon, where the carbon atoms arranged in a variation of the face-centred cubic crystal structure called a diamond lattice. Diamond is less stable than graphite, but the conversion rate from diamond to graphite is negligible at ambient conditions. Diamond has the highest hardness and thermal conductivity of any bulk material. Those properties determine the major industrial application of diamond in cutting and polishing tools.

Most natural diamonds are formed at high-pressure and high-temperature conditions existing at depths of 140 to 190 kilometres in the Earth mantle. Carbon-containing minerals provide the carbon source, and the growth occurs over periods from 1 billion to 3.3 billion years. Diamonds are brought close to the Earth surface through deep volcanic eruptions by a magma which cools into igneous rocks known as kimberlites and lamproites. Diamonds can also be produced synthetically in a high-pressure and high-temperature process which approximately simulates the conditions in the Earth mantle. An alternative and completely different growth technique is chemical vapour deposition. Several non-diamond material, which include cubic zirconia and silicon carbide and are often called diamond stimulants, resemble diamond in appearance and many properties. Special gemological techniques have been specially developed to distinguish natural and synthetic diamond stimulants.

The Blue Whale

The blue whale is a marine mammal belongs to the suborder of baleen whales. It can grow up to 33 metres in length and 180 metric tons or more in weight; it is the largest mammals know to have existed in the ocean.
The blue whale body, long and slender can be various shades of bluish-grey dorsally and somewhat lighter underneath. Blue whale was abundant in nearly all the oceans until the beginning of the twentieth century. For over 40 years, the blue whales have been hunted almost to extinction by whale hunter until they are protected by the international community in 1966. Some report on the 2002 estimated that there were 5, 000 to 12, 000 blue whale in worldwide. It can be located in at least five groups. Blue whales are from a family that includes the humpback whale, the fin whale, Bryde’s whale, the sei whale and the minke whale. The family Balaenopteridae is believed to have diverged from the other families of the suborder Mysticeti as long ago as the middle Oligocene. However, it is known when the members of those families diverged from each other.
The blue whale has a long tapering body that appears stretched in comparison with the stockier build of the other whale. The head is flat and U-shaped and has a prominent ridge running from the blowhole to the top of the upper flip. The front part of the mouth is thick with baleen plates which are around 300 plates handing from the upper jaw, running 0.5m back into the mouth. Between 60 and 90 grooves run along the throat parallel to the body length. These pleats assist with evacuating water from the mouth after lunge feeding.
Blue whales can reach speeds of 50 kilometres per hour over short bursts, usually when interacting with other whales, but 20 kilometres per hour is a more typical travelling speed. When feeding, they slow down to 5 kilometres per hour. Blue whales most commonly live alone or with one other individual. It is not known how long travelling pairs stay together. In a location where a high concentration of food is, there will be as many as 50 blue whales will scattered over a small area. However, they do not form the large close-knit groups seen in other baleen species. Blue whale feed almost on krill, though they also take small numbers of copepods.
