The environment of an organism determines the selection pressures on it. For example, organisms with the ability to camouflage in a forest environment are more likely to survive, and be selected to pass their traits on.
A prediction is a guess what might happen based on observation.
Here are some steps to think about to make a dependable prediction:
Collect data using your senses, remember you use your senses to make observations.
Search for patterns of behavior and or characteristics.
Develop statements about you think future observations will be.
Test the prediction and observe what happens.
A hypothesis is a possible explanation for a observation or problem that can further be tested by experimentation. Hypothesis' are also known as educated guesses.
Here are the steps to form a hypothesis:
When developing a hypothesis think about any observations or previous knowledge you know about the variables.
Express what you think will be the effect of changing one of the variables (Independent variable) on the other variable you expect to change (Dependent variable).
Develop your hypothesis using a statement.
A example of a hypothesis statement would be, As the (independent variable) ( describe how you would change it) , then the (dependent variable ) will (describe the effect)
Answer:
brown in summer, grey in winter -> camouflage from predators
storing fat during the summer -> gives them extra energy in the winter when there is less food
antlers with forward projections -> allows them to dig in the snow to uncover more food sources, also good for fighting predators
widely spaced hooves -> easily walk on snow and to dig for more food
migrate in herds -> find new area for more food & escape extreme weather, predators, and pesky bugs
Explanation:
If the substances preform the same in a variety of test, the they are the same. This is because they should always be tested in multiple categorys to see if they are the same or at least alike.
Answer:
Explanation:
Sickle cell anemia is a result of the point mutation, and in a change in just one nucleotide in a gene for hemoglobin. This mutation will cause the hemoglobin in the red blood cells to distort to a sickle shape when deoxygenated. "The sickle-shaped blood cells clog in the capillaries, cutting off circulation."
