As humans plants also need oxygen to breathe they only take in carbon dioxide to do photosynthesis.So they wont do photosynthesis at night and so they only need to breathe. even though their stomata are closed at night some oxygen can go inside. and this is how plants breathe when their stomata are … Enzymes change carbon dioxide to glucose.
Answer:
Symbiosis
Explanation:
Termites are the important insects due to its role in in nutrient recycling in the terrestrial ecosystems. Termites eat wood. The wood contain cellulose, a complex carbohydrate which is cannot be digested by most insects such as termites. For the breakdown and digestion of wood is carried out by the microorganisms present in the hindgut of the termites. The microbes live in the gut as a symbiont. The microbes break down cellulose into simple sugars and fatty acids which are easily absorbed into the cells of the termites.
Science is an organized way of using evidence to learn about the natural world.
The goal of science is to investigate and understand the natural world, to explain events in thenatural world, and to use those explanations to make useful predictions.
The Scientific Method Itself:
I. Observations:
Whether they start with a problem or not, scientists make careful observations.
Observations are a way to collect data (recorded observations or information) about events or processes in a careful, orderly way, using the senses (sight, hearing, touch, taste and smell).
Two types of data include:
a) Quantitative data: Are observations which collect data that can be directly measured or counted.
b) Qualitative data: Are observations involve making careful descriptions or drawings and do not involve numbers.
Inference: A logical interpretation of an observation based on prior knowlege. An educated guess as to what is occurring.
II. Hypothesis:
A proposed scientific explanation for a set of observations. Scientists devise hypotheses based on logical inferences, prior knowledge and informed, creative imagination.
Hypotheses may be tested by controlled experiments, or by collecting additional data.
III. Controlled Experiment:
A way to test a hypothesis by testing a single variable by changing it while keeping all other variables the same.
Variable: Any factor during an experiment that could change and affect the results (Examples: Temperature, pressure, amount of light, color of light, human error, etc......)
Manipulated variable: The factor in an experiment that is deliberately changed to test the hypothesis.
Controlled variable: any factor during an experiment that a scientist purposely keeps the same.
During the experiment, a scientist divides the tests into 2 groups, the control setup and the experimental setup.
Experimental setup: The part of the experiment that contains the manipulated variable.
Control setup: The part of the experiment that does not contain the manipulated variable. It may be called the placebo.
Answer:
The kinetic energy is transferred from the ball to the bumper. The bumper gives the same energy back and the ball eventually stops due to friction of the ground.
