1. What is viticulture?
Answer: The study of the growing of grapes (mainly for wine).
Interesting Information:Viticulture is a branch of horticulture that studies how to grow grape vines and how best to harvest grapes. The word comes from Latin, and in that language means "vine" or "wine growing".
Difficulty: Very Easy.
From Quiz: Viticulture for Kids!
Some incorrect choices:
The study of the manners involved in wine drinking., The study of the types of cheese that should be paired with wine., The study of insects known as vites.
2. Trees create energy through a process called photosynthesis. What gas is given off during this process?
Answer: Oxygen
Interesting Information:All life requires energy, and trees are no exception. Their leaves contain the green pigment chlorophyll, which enables them to convert carbon dioxide and water into energy and oxygen. The energy is stored in the form of sugars and the oxygen is released into the atmosphere. The Amazon rainforest is often called the 'lungs of the world' because of the large amount of oxygen its trees provide. This is one of many reasons why we need to preserve our rainforests.
Difficulty: Easy.
From Quiz: Wonderful Trees
Some incorrect choices:
Carbon dioxide, Nitrogen, Argon
3. In the air that we breathe we actually need a gas called oxygen. What percentage of the atmospheric air is oxygen?
Answer: About 20%
Interesting Information:The air at sea level (where most of the people on earth live) contains around 78% nitrogen plus 21% oxygen, nearly 1% argon and 0.04% carbon dioxide. For humans, nitrogen and argon are inert. This means that we can't use this gas to keep us alive, but it does not harm us either. As only about 20% of air is oxygen, when we take a breath of about 500mL of air only 100 mL is used by the body.
Difficulty: Easy.
From Quiz: The Air That I Breathe
Some incorrect choices:
Nearly 100%, Less than 1%, There is no oxygen in air
4. Biochemistry is an important topic and is named for two other sciences. Which two sciences are these?
Answer: Biology and chemistry
Interesting Information:Biochemistry is more similar to biology, but contains lots of chemistry too! Chemistry looks at lots of things, but biochemistry deals specifically with chemistry in living organisms ("bio" is Greek for "life"). This means we take questions like "how do we digest food?", "how do our bodies fight illness?", and "how do we stay alive?" and try to answer them from a molecular level.
Difficulty: Very Easy.

22. Living things are usually called [organisms] and there are seven things that living things do that will distinguish them from non-living things.
Living things will take in food from which they will produce and release energy. This process of feeding the body is called [nutrition]. The release of this energy, which happens in the cells, is called [respiration]. When this energy is released, it will generate a number of other processes. One of those is a change in position, which is called [movement]. In some living things, such as animals, this process happens a lot quicker than in other living things, such as plants. This is an indication that an animal may have a higher [metabolic] rate than a plant. In basic terms, this rate is the amount of energy that is used up over a length of time for a certain activity. Another is the disposal of waste products from the body, and we call this [excretion].
As they get older, living things are likely to get bigger, in a process defined as [growth] and, as they mature, they may [reproduce], which is giving birth to young. Finally, a living thing may experience a feeling such as [irritability], which is an indication that it is [sensitive] to the things around them.
Answer:
Interesting Information:We all understand that human beings are living things and that they, as a group, will perform all of the functions we described above and will develop further below. But, before we do, ask yourself this, is a motor car a living thing or a non-living thing? After all, it does take in fuel, it can move, and it can excrete waste. Think about the human being vs the motor car as we explore these seven characteristics a little bit deeper and make your own mind up.
Nutrition is a living thing utilizing the materials from its environment so that it can generate energy to work through all of its other functions. These foods may be things such as proteins, fats and carbohydrates. Most plants, for example, will draw nutrients from carbon dioxide and water and they will convert them into energy using the light from the sun. This is a process called photosynthesis.
Once the nutrients enter the cells they are broken down and glucose, a form of sugar, is created and, when it interacts with oxygen, it releases energy. This process is called respiration. There are two forms of respiration: aerobic, which involves oxygen in the process, and anaerobic. The latter does not use oxygen but another chemical to break down the glucose. This anaerobic process is also called fermentation.
As stated above, this release of energy is used in a number of ways. The first is movement, and all living things will move... yes, even that giant oak tree. It may move slowly and, at times its movements may be difficult to see, but it will move. Excretion of waste matter from the body of a living thing is vital. The waste materials may be toxic, and they can cause harm or poison the cells if not disposed of. Growth is the creation of new cells and reproduction is the ability that organisms have to produce offspring.
The final characteristic of an organism is sensitivity. There are various stimuli around living things. These include other chemicals, temperature, water, gravity and light. Living things will sense these and they will respond to them. For example, if the temperature drops suddenly, there's a good chance that the organism will respond by shivering.
Difficulty: Hard.

24. Most vineyards in the world are found between 30 and 50 degrees latitude in both the northern and southern hemispheres. Why is this?
Answer: Viticulturists find that climate for their grapevines is best in these areas.
Interesting Information:Most of the vineyards in the world are found between the latitudes of 30° and 50° in each hemisphere. This is mainly because of the climate in these areas. In the summer, the days are sunny and warm, conditions that help grapevines grow. In the winter, it gets cold, but not too cold, resulting in conditions that help grapevines to rest without damage from freezing weather.
Difficulty: Very Easy.

26. When your blood arrives at the lab, sometimes it needs to be separated into its different components. What is the name of the machine that separates the blood?
Answer: Centrifuge
Interesting Information:A centrifuge is a machine that holds lots of blood specimens at one time. When you turn it on, it spins the blood tubes very fast (about 3000 revolutions, or turns, per minute). This causes the heavy parts of the blood to move to the bottom of the tube while the watery part of the blood (the lighter part called plasma) stays near the top. This is important as the plasma is used for some tests and the cells for others.
Difficulty: Easy.
From Quiz: In the Blood
Some incorrect choices:
Microscope, Auto-analyzer, Flow cytometer
27. The brain tells the lungs to expand, which sucks air in through the nose or mouth, then down into the lungs. Why is it better that that air reaching the lungs (inspiration) is better when it travels through the nose?
Answer: The nose has little hairs which stop foreign matter entering the lungs
Interesting Information:When we breathe, the air nearly always enters our nose where hairs called cilia trap dust, pollen, mould and other environmental contaminants. The nose also moisturises and warms the air before it reaches the lungs. If the mouth is used for breathing none of these things happen but the distance to the throat is shorter and wider so air can reach the lungs quicker if needed.
Difficulty: Easy.
From Quiz: The Air That I Breathe
Some incorrect choices:
It does not matter which way the air gets to the lungs, It is quicker when it goes through the nose, It is less painful when air enters the lungs from the nose
28. Some people talk about this part when they are in love. Which organ pumps blood for my entire body?
Answer: heart
Interesting Information:The heart is the first organ that is formed in our bodies. It pumps the blood that carries nutrients to the entire body and also transports waste our body does not need. The average human heart beats about 100,000 times a day, sending 2,000 gallons of blood surging through the body, in over 60,000 miles of blood vessels.
