How does the speed of light be affected as it enters materials with different densities?
Based on the identified problem, which of the following can be considered as a testable hypothesis?
Density is directly proportional to the speed of light.
Density and speed of light are two characteristics of refraction.
When light travels from a material with greater density to a material with lower density, light speeds up.
Speed of light affects the density of materials where it travels.
How does the speed of light be affected as it enters materials with different densities?
What is the independent variable in the experiment?
Time
Distance
Speed of Light
Density of the materials
How does the speed of light be affected as it enters materials with different densities?
What is the dependent variable in the experiment?
Time
Distance
Speed of Light
Density of the materials
How does the speed of light be affected as it enters materials with different densities?
Which of the following must not be included when writing a methodology?
Describing a sample
Writing the accepted hypothesis
Identifying methods for data gathering
Providing instructions on data analysis
What happens to the molecules of oxygen from D to C?

Philippine crocodile is classified as an endangered species, what does it mean?
The species is in danger of extinction and have already been reduced to critically low numbers or have experienced drastic habitat.
The species may become endangered within a foreseeable future throughout their range unless the steps are taken to prevent decreasing.
The species may be considered threatened with extinction in the near future, although it does not currently qualify for the threatened status.
The species are likely to become endangered unless the circumstances threatening its survival and reproduction improve
What makes plants capable of performing photosynthesis?
Having chlorophyll which can be found in the chloroplast.
Through the petiole located in the stem-like part of the leaf.
Using the veins or the net-like patterns on the leaf.
Using the stipules located at the base of the petiole.
What happens to the glucose that is formed during photosynthesis?
Glucose is secreted by the plants through the leaves.
Glucose is either stored or used immediately as food.
Glucose is combined with oxygen during respiration.
Glucose stays in the leaves until it is replaced by newly formed glucose.
What are the reactants needed in cell respiration?
Water and glucose
Water and carbon dioxide
Carbon dioxide and oxygen
Glucose and oxygen
