DNA is stored in chromosomes

The cell nucleus is the most important organelle, and it’s here that we find our DNA (deoxyribonucleic acid) packaged up tightly into structures called chromosomes. Chromosomes are long thread-like structures made of a DNA molecule and protein. During cell division, chromosomes coil up tightly into X shapes and are more easily visible under a microscope. Human cells have 23 pairs of chromosomes.

A DNA molecule is made up of a series of nucleotides arranged in 2 strands that resemble a ladder and twist to form a double helix.

Nucleotides are made up of a base, a sugar and a phosphate. The 4 bases – adenine (A), guanine (G), cytosine (C) and thymine (T) – pair with each other (A with T and G with C). It is the order or sequence of these base pairs that provides the information needed for the growth and development of our bodies. It can help to visualise the bases as letters in the alphabet that form words when they are in a certain order. These ‘words’ are calledgenes and act like a set of instructions for our cells.

Inherited Trait or Instinct

·        Inherited traits are physical characteristics and behaviors that an organism gets from its parents.  It is born with them.

·        Eye color, hair color, freckles, skin color and dimples are all inherited traits in humans.  Other animals and plants also have inherited traits…some might include fur color, type of feet or body covering, flower color, or type of leaves.

·        Instincts are inherited behaviors.  Instincts do not have to be taught. 

·        Breathing, blinking, hibernation for some animals, migration for some animals, sleeping patterns, roots growing down in the ground, and plants growing toward the light are all examples of instincts.

Some traits occur because of the environment. Environment is the surroundings in which you live. Organisms develop some traits because of their environment.

A 5^th grader living in the Andes Mountains of Peru may have a larger lung capacity than a 5^th grader living near sea level in southern California.  To adapt to the high altitudes, people living at higher altitudes often have larger lung capacities than those who live at lower altitudes.

Look at the tree in the picture below. What caused it to grow sideways instead of straight up? Growing sideways is NOT an inherited trait in this tree. It is not learned. It is not instinct. It grows sideways because of its environment. The wind blows constantly where it lives. The wind caused the tree to grow sideways.

Remember that an instinct is a behavior with which an organism is born. A learned behavior helps the organism to be successful in the environment.

Some Inherited Traits

Vocabulary Needed

Trait  : a quality that makes one person or thing different from another

Inherited trait : to have (a characteristic, disease, etc.) because of the genes that you get from your parents when you are born.

Acquired trait  : to get or learn a trait (something)

Behavior : the way a person or animal acts or behaves

Offspring: the young of an animal or plant 

Adapt :to change (something) so that it functions better or is better suited for a purpose 

Perish : to die or be killed

Reproduce:to produce babies, young animals, new plants, etc

Learned behavior: a behavior that people get or have because of learning or experience 

Instinctive behavior: a behavior relating to or based on instinct : based on feelings or desires that do not come from thinking or learning

Hibernation/hibernate :to spend the winter sleeping or resting

Migration/migrate: to move from one area to another at different times of the year

Dormancy/dormant:not active but able to become active

TAXONOMY

The taxonometric way of classifying organisms is based on similarities between different organisms. A biologist named Carolus Linnaeus started this naming system. He also chose to use Latin words. 
Taxonomy used to be called Systematics. That system grouped animals and plants by characteristics and relationships. Scientists looked at the characteristics (traits) that each organism had in common.

RULES OF TAXONOMY

Every known living organism on Earth is classified and named by a set of rules. Those rules are used by all scientists around the planet. The names are called scientific names, not common names. Common names are the ones you might use when talking with your friends. You call your pet a dog or a cat (the common name). Scientists call those animals by a set of several names like Canis familiarus. That's a dog.

CLASSIFICATION

Scientists believe that there are over 10 million different kinds of lifeforms, or species, on Earth. Imagine trying to study and understand the lives, patterns, behaviors and evolution of so many different kinds of organisms. In order to make their job easier, scientists classify living things into groups based on how they are the same and how they are different.

Scientists who classify living things are called taxonomists. It is their job to look at every kind of living thing and determine how they are similar and how they are different to other living things.

Modern taxonomy

Kingdom	Cell characteristic	Other characteristics
Bacteria	single-celled	live alone or in colonies  cannot move independently no nucleus
Protists	mostly single-celled	live alone or in colonies some can move independently,some cannot some must find food,some make food
Fungi	mostly multi-celled	live alone or in colonies do not move independently feed on decaying matter or living organisms
Plants	multi-celled	specialized cells do not move from place to place produce food using sunlight
Animals	multi-celled	specialized cells organized into complex systems  can move independently feed on other kingdoms

Science Review

1. Gases in the air, what are they?  Nitrogen, oxygen and other gases such as carbon dioxide.


2. Why are these gases beneficial? Plants need nitrogen and we need oxygen to survive. Trees absorb carbon dioxide and give off oxygen.

3. What is air pressure? It is the weight of air as it is pressed down.


4. What are the four layers of the atmosphere? Troposhere, stratosphere,mesosphere and thermosphere

5. Which is the most important layer for human life? Troposphere

6. What is the grrenhouse effect?

Earth's atmosphere does the same thing as the greenhouse. Gases in the atmosphere such as carbon dioxide do what the roof of a greenhouse does. During the day, the Sun shines through the atmosphere. Earth's surface warms up in the sunlight. At night, Earth's surface cools, releasing the heat back into the air. But some of the heat is trapped by the greenhouse gases in the atmosphere. That's what keeps our Earth a warm and cozy 59 degrees Fahrenheit, on average.

Greenhouse effect of Earth's atmosphere keeps some of the Sun's energy from escaping back into space at night.

The point is, if the greenhouse effect is too strong, Earth gets warmer and warmer. This is what is happening now. Too much carbon dioxide and other greenhouse gases in the air are making the greenhouse effect stronger.

Every place has its own climate, whether Arctic cold, tropical warm, or something in between. Averaging them all together makes global climate.
