Light acts like a particle when it bounces off the surface, and acts like a wave when it bends around objects.
Answer:
When your graphing to data from an experiment.
Explanation:
You use any type of graph when you're doing an experiment because, in the beginning, you start by marking where you started then as time goes on you mark it accordingly. For example, say your starting at 5cm on a plant so on the line/bar graph you make 0 you 5 since that is where you're starting at. when you water the plant you decide to give it 10cm of water and put it in the sun constantly. A week later of sun and water it grew 10cm, so you mark it on your line/bar graph to show how much it grew over time. Make a little bit more sense?
I believe the answer is photosynthesis
Answer:
Renewable Energy Resources.
Explanation:
Unlike fossil fuels which cannot be recovered when destroyed, these sources of energy can be recovered by a means of recycling . Recycling here reduces solid wastes which is one of the causes of land pollution.
Hydroelectric schemes can only be built in mountain regions where rainfall and rivers are plentiful which involves upset of aquatic ecosystem. This poses a dangerous pollution problem though.
Wind generators and solar panels are not very efficient energy producers. However, future schemes for producing solar energy via solar satellites are promising.
The right answer is law of segregation
Mendel derives from his observations two fundamental principles, to which will be added later a third resulting. In his case, experiments on peas enabled Mendel to formulate the principles involved in heredity.
<u>Mendel discovers that:</u>
* A character can present two different forms (today called alleles or homologous genes).
* An organism inherits two factors for each trait (Mendel's hereditary factors are now called "genes").
* The dominant factor masks the recessive factor. Mendel noted the dominant factor using a capital letter and the other, the recessive, using the same letter but in lower case
.
* The two factors separate during gamete formation (Segregation law that corresponds to the separation of homologous chromosome pairs during meiosis)
.
* The pairs of factors separate independently of each other (independent segregation law that corresponds to the independent assortment of chromosome pairs homologous to metaphase 1 of the first meiotic division).
