Proteins are the major 'working molecules' within every organism. Among their many jobs, proteins catalyse reactions, transport oxygen and defend organisms from infection- like a doctor for organisms. The precise shape of each protein, and its genes, along with the amino acids it contains, determines what it does, some develop different traits and they may also copy traits of related organisms, which means some organisms may create more protein depending on their traits.

C. Teeth, chewing
D. Saliva, amalyse )
Answers
f human cells could use the food eaten in that form, there would be no need for a digestive system. The digestive system changes the food into a form that can be used by the cells and that enables the nutrients to get into the blood so they can be transported throughout the body
There are two kinds of digestion: mechanical and chemical. Mechanical digestion involves physically breaking the food into smaller pieces. Mechanical digestion begins in the mouth as the food is chewed. Chemical digestion involves breaking down the food into simpler nutrients that can be used by the cells. Chemical digestion begins in the mouth when food mixes with saliva. Saliva contains an enzyme (amylase) that begins the breakdown of carbohydrates. (An enzyme is a protein that can catalyze certain biochemical reactions).
The Digestive Process
Mouth
Food is chewed into smaller pieces. Adults have 32 specialized teeth—teeth that can grind, chew, and tear different kinds of food. The tongue is an organ consisting of skeletal muscles (voluntary muscles) that move the food around the mouth to allow for efficient mechanical digestion. Salivary glands beneath and in back of the tongue secrete the saliva that allows for easier swallowing of food and the beginning of chemical digestion.
↓
Pharnyx
Swallowing forces the chewed food through a tubular entrance (pharynx) to the esophagus (food tube). As food is swallowed a flap-like valve, the epiglottis, closes over the trachea (windpipe) to prevent food entering the windpipe and causing choking.
The stomach starts chemical digestion of protein. Secretions from the stomach lining consist of about two liters of hydrochloric acid (HCl), pepsin, and other fluids that make up gastric fluids each day. The fluid is extremely acidic and it helps kill bacteria and other pathogens that may have been ingested.
The thick mucus also produced by the stomach lining usually keeps the acids from damaging the lining. If not enough mucus is produced or if too much acid is produced, peptic ulcers form. Heredity, stress, smoking, and excessive alcohol intake can make the ulcers worse. The condition can worsen and bleeding ulcers can result.
Food stays in the stomach for approximately 3-4 hours and moves through another sphincter muscle to pass into the small intestine.
↓
Small intestine
Nearly 7 meters in length, the small intestine is folded and curled around a small area in the abdominal cavity. The inside surfaces of the intestine are covered with projections called villi. These finger-like structures are covered in smaller projections called microvilli and work to absorb food molecules that have been broken down by the processes of chemical digestion.
The small intestine has three distinct parts: the duodenum, the jejunum, and the ileum. Each day, about 9 liters of fluid enters the duodenum. Most chemical digestion takes place in the duodenum by chemicals secreted by the liver, pancreas and small intestine. The other two sections of the small intestine, the jejunum and the ileum, absorb food molecules by way of the villi directly into the blood stream.
Large intestine
The large intestine receives the material “left-over” from chemical digestion that is basically nutrient free. Only water, cellulose, and undigestible materials are left. The main job of the large intestine is to remove water from the undigested material. Water is quickly removed from the material through villi and returns to the blood stream.
Liver
The liver is a large organ located just above the stomach. The liver produces bile which helps digest lipids. Bile is stored in the gallbladder and flows from the gallbladder to the duodenum where it helps digest fats.
The picture at the left shows a human liver.
Gall bladder
The gall bladder is a small, greenish organ located just under the liver. It stores bile produced by the liver until it is secreted directly into the first section of the small intestine.
Pancreas
The pancreas has three important functions that help the digestive system change food into a form that can be used by the cells.
1) It produces enzymes which help break down proteins, lipids, and carbohydrates.
2) It produces the hormone, insulin, which helps regulate blood glucose levels.
3) It produces sodium bicarbonate which helps to neutralize stomach acids.
Checking for Understanding.......
1. What is the function of the digestive system?
To change ingested food into a form that can be used by the cells, to get the nutrients into the blood stream, to reabsorb water, and to eliminate wastes.
2. What is the function of the following parts/organs of the digestive system?
a. mouth—houses teeth, salivary glands and tongue for mechanical and chemical digestion
b. teeth—chews, grinds, and tears food into smaller pieces
c. esophagus—food tube; leads from the pharynx to the stomach
d. stomach—
churns food to mix with gastric enzymes and acid to continue mechanical and chemical diges

Eukaryotic cells are typically larger and more complex than prokaryotic cells, which lack a true nucleus and other membrane-bound organelles.
Eukaryotic cells also have cytoskeleton, which helps in maintaining the shape of the cell and movement of organelles. They have a plasma membrane that controls the exchange of materials with the environment and a cytosol, a gel-like fluid that fills the cell and surrounds the organelles.

Louis Pasteur (December 27, 1822 – September 28, 1895) was a French chemist and microbiologist. Pasteur was familiar with Redi’s work and was fascinated by the idea that covering meat could protect it from growing maggots or other organisms that could cause disease. Pasteur devised the process of pasteurization, which is the process of heating liquids to kill bacteria and other germs that may be present. This process is still widely used today to make sure that many of the liquids we drink are safe, such as milk and juice. There are other pasteurized foods too, like syrups, vinegar, and cheese.
So how did Pasteur disprove spontaneous generation? Pasteur used a special flask to show that sterile broth will remain sterile unless exposed to the environment.
Pasteur used a special flask to demonstrate that heating a liquid kills bacteria. His experiments also showed that the broth would stay clear if the bacteria were trapped in the flask’s neck. If he broke the neck off the flask, the broth was soon full of bacteria.
Pasteur put clear meat broth into a flask with a curved neck. The shape of the flask allowed air to enter but kept out bacteria. He heated the flask to boiling and let it sit for several days.
When he returned, the broth was still clear because the bacteria were trapped in the neck of the flask. Then, he went one step further: he broke the neck off the flask, exposing the broth to air. A few days later, the broth was cloudy! Pasteur concluded that bacteria cannot suddenly arise from the broth. Bacteria can only be produced from living bacteria. Life comes from life!
The experiments by Redi and Pastuer helped to convince people that spontaneous generation was not based on fact, that life must exist first to reproduce and create more life.
Describe Pasteur’s results and how they helped disprove spontaneous generation.

At which point on the roller coaster will the car have the greatest amount of kinetic energy? Explain why.
Answers
Because at that point the car will be travelling the fastest.
The point at which the kinetic energy of the car is maximum is point X because of the maximum speed of the car at this point.
What is kinetic energy?Kinetic energy is the energy of motion. When an object is in motion, it possesses kinetic energy. It is defined as the energy that an object possesses due to its motion. The amount of kinetic energy an object has is dependent on its mass and velocity.
The formula for kinetic energy is KE = (1/2)mv², where KE is kinetic energy, m is the mass of the object, and v is the velocity of the object. This means that the greater an object's mass and velocity, the more kinetic energy it possesses.
Kinetic energy can be transformed into other forms of energy, such as potential energy or heat, through various processes.
