Please Help
B. Swamp
C. Lake
D. River
The correct answer is D. River
Explanation:
Rivers are one of the most common ecosystems. A river is characterized by flowing water in which biotic factors (animals, plants, bacteria, etc.) and abiotic factors (rocks, water, minerals) interact. Also, they cross major ecosystems such as forests or rainforests.
Moreover, rivers are unique because they contain fresh rather than salt water as in the ocean, and they are always flowing while in a marsh, swamp or lake the water does not flow. This suggests the ecosystem is the photograph is a river because in this the water flows and as a result of this, there is a strong current which is possible in a river but not in a lake, marsh or swamp.

List any observations you made as the light rays passed from the air on the top of the screen to the selected material on the bottom of the screen.
Evidence
Using the protractor, measure the angle as the light passes from the top material to the bottom material on the screen. Also, note the index of refraction for each as indicated on the screen.
Trial One
Air on top
Angle:
Index of refraction:
Air on bottom
Trial Two
Air on top
Angle:
Index of refraction:
Water on bottom
Trial Three
Air on top
Angle:
Index of refraction:
Glass on bottom
In this lab report, you are required to record data and observations about the properties of light as it passes through different materials. You will fill in a data chart with information from each trial.
For each trial, you will have air on the top and a different material on the bottom of the screen. As the light rays pass from the air to the material, you need to make observations and note any changes you see. These observations could be related to how the light behaves or any visible effects.
Next, you need to measure the angle as the light passes from the top material to the bottom material using a protractor. Additionally, note the index of refraction for each material as indicated on the screen.
Here is a step-by-step breakdown of what you need to do:
1. Trial One:
- Air on top
- Make observations as the light rays pass from the air to the selected material on the bottom.
- Measure the angle using a protractor.
- Note the index of refraction for each material.
2. Trial Two:
- Air on top
- Make observations as the light rays pass from the air to the selected material on the bottom.
- Measure the angle using a protractor.
- Note the index of refraction for each material.
3. Trial Three:
- Air on top
- Make observations as the light rays pass from the air to the selected material on the bottom.
- Measure the angle using a protractor.
- Note the index of refraction for each material.
Remember to fill in the data chart completely for each trial, including the angles and index of refraction values.
I hope this explanation helps you understand what you need to do in your Properties of Light Lab Report. If you have any further questions, feel free to ask!

Answer:
D. The variable in an experiment that is manipulated by the scientist.
Explanation:
The independent variable is what is purposely changed or controlled to see what the effect is.

The different forms a gene may have for a trait are called alleles. These are variations of a gene present on homologous chromosomes. A trait in an individual is determined by the two alleles inherited from their parents.
The different forms a gene may have for a trait are called alleles. These are variations of a gene that occur at the same relative locations on homologous chromosomes. For example, in a diploid organism where a single gene controls a characteristic, there can be two genetic copies, or alleles, that may or may not encode the same version of that characteristic.
A slight change in the sequence of nucleotides within a gene can result in different alleles that code for different traits. For instance, the different alleles for the gene that determines blood type in humans are sequence A, sequence B, and sequence O. The blood type is a trait determined by the two alleles that are inherited from the parents.
It's important to note that while an individual can only have two alleles for a given gene, it's common in a natural population to encounter more than two alleles for any given gene, a phenomenon referred to as multiple alleles.
