Answer:
Then what is the question???
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:
100% of the offspring will be green.
0% of the offspring will be yellow.
Explanation:
Since green is the dominant allele, those traits are seen. If the dominant color was yellow, then the yellow would have been seen. The dominant allele always masks the recessive one.
Answer: a. Aerobic respiration, b. Anaerobic respiration.
Explanation: Oxygen is an essential component for aerobic respiration because it is at the end of the electron transport chain, where it accepts electrons and picks up protons to give out water.
The final acceptor of electrons in the electron transport chain during aerobic respiration is oxygen.
The final electron acceptor in the Anaerobic respiration are inorganic molecules such as sulfates. Inorganic molecules are used rather than Oxygen.
Oxygen
Answer:
If your cartilage, muscles, or tendons put too much pressure on a nerve, it might not be able to work right. This can cause numbness. An injury or overuse can cause a pinched nerve. Sometimes it's due to health problems like arthritis, a narrowing of the spaces between the bones in your spine, or a tumor on the spine.
hope this answer helps you.....
