Amazing facts in Basic Science

Chewing aspirin during a heart attack may be a life saver. This is true because the drug inhibits platelets from forming a clot that can block an artery of the heart, thus stopping a heart attack

The kneecaps of newly born babies are not made of bone. Rather, they are little bits of cartilage which ossifies (turns from cartilages to bone) from age 2 to 6

Ice cubes made with fresh water are white in color while those made with boiled water are crystal clear

🐈 Cats 🐈 are unable to taste sweet things

🍎 Apples 🍎 actually float on water. Other fruits that float on water include 🍋 lemons, 🍌 bananas, 🍐 pears, and 🍊 oranges

Rain water contains vitamin B12.

Vitamin B12 is an important nutrient that keeps the blood cells and neurones healthy. It also assist in building the DNA (a genetic material present in the cell's nucleus). Vitamin B12 also aid in the prevention of megaloblastic anemia which makes people weak and tired

Rasceta is the name given to the lines on your ✋ palm ✋

Goats have rectangular pupils in their eyes.

Think of the pupil as a hole located in the centre of the iris within of the eye.

Note: To get an idea of an iris; 'when one is said to have blue eyes', it's because the iris is blue

Among all land animals, 🐘 Elephants 🐘 have the longest gestation period.

They stay pregnant for 22 months before giving birth to their young

🦘 Kangaroos 🦘 can't walk backwards


NOTABLE POINTS IN Basic Science

Disaccharides are composed of two monosaccharides joined together; thus are also referred to as double sugars.

Disaccharides are often added as sweeteners to food; for instance, the table sugar called sucrose is a disaccharide often used by us to sweeten our tea.

Maltose is another disaccharide used as an ingredient for making malt drinks, chocolates and candies.

The breast milk contains the disaccharide Lactose.

Lactose is very vital for the normal growth and development of infants.

In adults, disaccharides are non essential nutrients. This implies that we can live without them as adults.

Below is a summary of monosaccharides that make up disaccharides (double sugars).

  • Maltose = Glucose + Glucose

  • Lactose = Glucose + Galactose

  • Sucrose = Glucose + Fructose

Other examples of disaccharides include trehalulose and isomaltulose

Polysaccharides are complex sugars. These are what we often eat whenever we eat carbohydrates.

We have four types of polysaccharides namely:

  1. Starch
  2. Glycogen
  3. Chitin
  4. Cellulose

 

  • Starchy foods include rice, cassava and yam.

  • Glycogen is stored in the human liver; as a result of the joining of many glucose molecules.

  • Chitin is a major component of insect and anthropod's skeleton.

  • Cellulose is a major component of a plant's cell wall. They cannot be digested when eaten by humans; hence they function as roughages.

Roughages are not classified as one the classes of food in humans. This is due to the fact that they aren't digested. They will rather facilitate the movement of bowels in the large intestine (colon); and for this reason, they can be very useful in treating constipation.

The uniqueness of man can be defined as that which makes man distinct from every other animal and living organism.

Humans are higher animals when compared to other animals.

Under the classification of living organisms, humans belong to an order termed primates and thus share the same characteristics (as primates). In addition to these features, they also have their unique characteristics.

The eyebrow is an area of dense, delicate hair just above the eye.

Eyebrows perform two main functions:

  1. Protects our eyes against sweat, rain, dirt and other atmospheric contaminants.
  2. It helps us express our emotions.
