Lab: Interdependence of Organisms

Interdependence Of Organisms

Question Being Answered:

How can the presence of one species benefit another in the same ecosystem?

Hypothesis:

If plants grow in soil that contains worms the plants growth will be greater because worms are able to help decompose organic matter and help distribute it through the soil in a form plants are able to use.

Process Of Lab:

In this lab you will grow two different groups of plants. Group A is considered the experimental group which will grow in soil with worms, Group B is considered the control group which will grow in soil without worms. After the plants grow you have to measure the plant growth for both groups and compare them.

Independent & Dependent

Independent Variable: Presence Of Worms

Dependent Variable: Plant Growth

Safety Procedure

Be sure to follow the safety procedure which means to

Wear safety goggles and lab gown while doing the experiment

Keep lab behavior purposeful

Look over the soil contents and make sure to follow warnings provided on any equipment

Wash hands and lab equipment once done with experiment

Treat living organisms with respect and provide proper care

Report any accidents that happen in the lab to your teacher

Lab Procedure

Step 1: Gather Materials

Two trays that are 10 cm 4’ deep

Potting soil

Lima bean seeds which need to be soaked overnight

Location with sunlight or growth lights

Worms

Graduated cylinder

Water

Black marker

Ruler with metric markings

Step 2: Prepare Two Trays Of Lima Bean Plants

Label the trays Control Group and Experimental Group

Add approximately 6-7 cm of soil to each tray

Plant 6 lima bean seeds in each tray being 2 cm deep and label the plants 1-6

Step 3: Give The Plants Water And Light During Sprouting Time

Keep the environments for both groups identical

Water all the plants following the watering schedule that was recommended on the seed packaging

Use the graduated cylinder to ensure the same amount of water is being given to both groups

Make sure all plants get the same amount of light

Step 4: Measure The Heights Of The Plants At The End Of Week 1

Measure the height of all twelve plants to the nearest cm. If a plant dies mark an x on the data table for that plant and write it in your notes

Use a calculator to find the average heights of the living plants in each groups

Calculate the difference in those average heights by subtracting the average height of the plants in the control group. Use this difference as a basis for comparison

Record measurement observations in your notes and the health of the plants such as leaf colors and size, wilting, unusual growth, brown spots, and any other marks you see

Step 5: Add Six Worms To The Soil Of The Experimental Group Of Plants

Write descriptive notes about the condition of the worms in your notes

Step 6: Measure The Heights Of The Plants At The End Of The Week 3

Repeat step 4

Step 7: Measure The Heights Of The Plants At The End Of Week 5

Repeat step 4

Step 8: Check The Health Of The Worms At The End Of The Study

Are the worms still alive?

Do they all seem healthy?

Have they changed in any way? If so list the ways changed

Are there any new worms

Be sure to write descriptive notes about their conditions in your notes

Step 9: Dispose Of All Material According To The Directions From Your Teacher

The diagram below shows a stack of rock layers. These layers have not changed position since they formed. Examine the diagram and answer the question that follows. If the age of Layer 4 is 400 million years and the age of Layer 1 is 500 million years, then the age of Layer 3 is A. older than 500 million years. B. between 400 million and 500 million years. C. 500 million years. D. younger than 400 million years.

Answers

The answer is B because if 4 is 400 million and 1 is 500 million it cannot go passed 500 million

The age of layer 3 will be between 400 million and 500 million years. Therefore, option (B) is correct.

Why rock dating is important?

Finding estimates of the ages of rocks is essential for identifying the speeds of geological processes as well as the history of geological occurrences. Some rocks may be used to determine the relative sequence of events. The most well-known methods are uranium-lead dating, potassium-argon dating, and radiocarbon dating.

Radiometric dating, which considers the ratio of two distinct isotopes in a sample, establishes the age of rocks. Geologists may use tools like these to assess the age of a material since radioactive isotopes degrade over a predictable period of time. mass spectrometer for thermal ionisation

A dominant gene that codes for white hair is represented by the symbol W. If a parent with the genotype WW is crossed with a parent of genotype Ww, what percent of their offspring will have white hair?
A. 25%
B. 50%
C. 75%
D. 100%

Answers

Answer:

D

Explanation:

Seeing as the gene is dominate, the hair would still be white evening it's Ww. For the hair to be a different color both parent would need a recessive gene (w), though neither does, meaning all the kids would have white hair.

Which statement best describes the relationship between protein, amino acids, and DNA? (1 point)
O DNA codes for proteins. Proteins are made up of amino acids.
O Amino acids code for DNA. DNA is made up of protein.
O DNA codes for amino acids Amino acids are made up of proteins.
O Amino acids code for protein. Protein is made up of DNA.

Answers

Answer:

Explanation:

The major relationship between protein and nucleic acid is the reproduction of DNA which contains the information on how cells are used together with RNA which helps to make protein. Both nucleic acid and protein they have four biomolecules which are common in both of them.

Short answer: Using a binary code, genes (DNA) specify how proteins (among other things) are to be synthesized.

Analogy: If DNA is a cooking book, genes are recipes, and proteins the dishes resulting from processing the recipe ingredients.

The relationship between protein, amino acids, and DNA is defined by the DNA codes for proteins. Proteins are made up of amino acids.As DNA codes for proteins.

DNA, RNA, and protein are all intently related. DNA carries the records vital for encoding proteins, even though it does now no longer produce proteins directly. RNA includes the records from the DNA and transforms that records into proteins that carry out maximum cell functions.
