sunlight.
Lesson Objectives
• Design an experiment to test your prediction.
• Explain how air temperature, air pressure, air density, and Earth's rotation interact to produce air circulations locally and globally.
• Explain how the absorption or reflection of sunlight may affect natural settings.
• Predict that different materials will absorb or reflect sunlight.
• Describe the consequences of the heat energy that is taken up by the atmosphere and what the atmosphere does with it.
• Explain how heat energy is transferred from the sun to Earth and the atmosphere.

Activity 2: Energy Absorption/Reflection (Online)
Instructions
Introduction
Follow the Procedure below. As you complete the lab, take notes about the lab so you can participate in the discussion. In this laboratory exercise, you will design an experiment to test how different materials reflect or absorb light.
Procedure
Part 1: Formulate a Hypothesis
1. Keep these questions in mind as you develop your hypothesis:
• Do some colors absorb more light than others?
• Do some materials absorb or reflect more light than others?
• How could you indirectly measure the amount of sunlight absorbed by an object?
2. Write a hypothesis, in if...then format.
Part 2: Design an Experiment
3. Design an experiment that tests the absorption and reflection of different materials.
4. Create a list of materials and a procedure to test your hypothesis.
5. Record your idea in your lab report for discussion. Note that you do not need to perform the experiment.
When you have finished, you will discuss with your classmates through a threaded discussion board. Print the Grading Rubric for the Threaded Discussion Board Activity and review the contents. Your teacher will use this rubric to grade your participation in this discussion.
ASSESS
Discussion: Energy Absorption/Reflection 1 (Online)
Read the discussion prompt and carefully write your response. Remember:
What you type here is public. A good rule of thumb is to only post things here that you would be
comfortable communicating in person.
Responses should be well written (use a spell-checker) and clearly address the issue being discussed. You
may wish to write your response in a word processing program, and then copy and paste it into the topic
response box.
Your teacher will review postings regularly. Any postings containing foul language or inappropriate topics
will be removed, and the posting student will be referred to the administration. If you are in doubt about
whether something is appropriate to post, either ask your teacher first, or just don’t post it.
Review the Grading Rubric for Discussion Board Activity. Your teacher will use this rubric to grade your
participation in this discussion. Be sure to contact your teacher if you have any questions.

In 1860, a scientist named Gregor Mendel used pea plants to determine the dominance of certain traits. In one of his experiments, he looked at the inheritance of pod color. Construct a Punnett square for a pea plant with YY phenotype for a yellow pod cross-pollinated with a pea plant with yy phenotype for a green pod.
A scientist hypothesized that when two pea plants, both having the genotype all of the offspring would have at least one dominant allele for either shape or color. Which conclusion is supported by the data in the dihybrid cross above?
Answer:
The conclusion is incorrect.
Explanation:
There is a chance that the offspring may have the genotype rryy, in which it has no dominant alleles.

Jennipher was asked by her mother to take a certain kind of fish in a bucket full of water so that she can prepare it for meal.when jenipher touched the fish she felt like an electric shock to her hand. what behavioural mechanism did the fish generate?
The fish use reacting behavioural mechanism in order to protect itself from the danger.
The fish uses reacting behavioural mechanism when the fish sense any type of danger surrounds it. This behaviour is a type of defense mechanisms which is used to defend and protect itself.
The fish apply electric shock in order to protect itself from the attackers and give harm to the other organisms which comes in contact with it so we can conclude that the fish use reacting behavioural mechanism in order to protect itself from the danger.

Most scientists agree that life began on earth approximately 3.5 billion years ago. What would a scientist need to do in order to test this hypothesis and gather evidence?
A: Recreate the composition of the atmosphere and oceans on Earth as they were 4.5 billion years ago.
B: Travel to a similar planet or moon in its own early formation and recreate the chemical reactions which took place on Earth.
C: Gather the raw materials, such as inorganic compounds, on Earth 4.5 billion years ago and recreate the chemical reactions that could have taken place.
D: This is not a testable hypothesis since there is no way to travel back 4.5 billion years or to run the experiment for the next 4.5 billion years.
Answer:
A
Explanation:
Today, the atmosphere holds about 21 per cent oxygen. ... When the first simple organisms appeared in the oceans more than 3.5 billion years ago, the atmosphere was mostly nitrogen, hydrogen, water vapor, and carbon dioxide
