Explanation
The brain loses fifty thousand neurons a day, but it still manages to maintain its basic patterns and memories. Despite the constant loss of neurons, the brain is capable of adapting and forming new connections between remaining neurons. This allows it to preserve its essential functions and retain memories.

Explanation
The potato was the staple food in Ireland during the 1840s. However, when the potato crop failed in 1840, it led to widespread famine and starvation among the population. The reliance on potatoes as the main source of sustenance meant that the failure of the crop had devastating consequences, resulting in mass starvations.

Explanation
Sharks can maneuver considerably faster than other fish because they have no bones. Unlike other fish, sharks have a cartilaginous skeleton, which is lighter and more flexible. This allows them to move their bodies with greater agility and speed through the water. The absence of bones also reduces their overall weight, making it easier for them to swim swiftly and change directions quickly.

Explanation
The explanation for the given correct answer is that despite the physical differences between sugar cane and sugar beet, the sugars that are refined from both sources have a similar taste. This suggests that the chemical composition of the sugars is similar, resulting in a similar taste when refined.

Explanation
The given statement suggests that textiles industries are as widespread as food industries because both supply basic human needs. This implies that just like food, textiles are essential for human survival and well-being. People require clothing and other textile products for protection, comfort, and self-expression. Therefore, the demand for textiles is widespread, similar to the demand for food. Both industries play a crucial role in meeting the basic needs of individuals and are therefore equally important in society.

Explanation
The given statement suggests that being totally colorblind is a rare condition in humans compared to many animal species. This implies that while there are numerous animal species that cannot perceive colors, humans generally have the ability to see colors to some extent.

Explanation
The given statement states that our skulls are made up of eight cranial and fourteen facial bones. This means that our skull is composed of a total of twenty-two bones. The cranial bones form the structure of the skull and protect the brain, while the facial bones make up the structure of the face. Together, these bones provide support, protection, and shape to our head and face.

Explanation
Diamonds are composed of pure carbon and are known for their exceptional hardness, being about 40 times harder than talc. This means that diamonds have a much higher resistance to scratching and are able to withstand more wear and tear compared to talc. The hardness of diamonds is what makes them highly valued and sought after in various industries, including jewelry and cutting tools.

Explanation
The given statement explains that the oceans hold approximately 97 percent of the world's water supply, while around 2 percent is in the form of ice. This implies that the majority of the Earth's water is found in the oceans, making them a significant source of water on our planet.

Explanation
Brain waves are the electrical patterns of activity that occur in the brain. These patterns can vary among different individuals due to factors such as genetics, age, and overall brain health. Additionally, brain wave patterns can also vary depending on the activity being performed. For example, during deep sleep, the brain waves may be slower and more synchronized, while during periods of intense concentration or stress, the brain waves may become faster and more desynchronized. Therefore, the statement that brain wave patterns vary among different people and in different activities is accurate.

Explanation
The answer "54 millions" refers to the time period when the ancestor of today's horse, called eohippus, first appeared. This indicates that the little mammal eohippus lived 54 million years ago, which eventually led to the evolution of the modern horse.

Explanation
The correct answer is "warms-blooded" because the statement suggests that although dinosaurs are classified as reptiles, some of them were warm-blooded. This implies that not all dinosaurs were cold-blooded like typical reptiles, but rather had the ability to regulate their body temperature internally.
