Answer:
PH is a scale used to specify the acidity or basicity of an aqueous solution.
Acid soils have a pH below 7
6.5 to 7.5 for basic soils
Because all organisms are made up of cells and there are different types of cells which carry different functions.
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)
Food chains showcase clear picture of who is eating who. But when we try to use them to characterize entire ecological communities i.e food web, certain problems arise. For example, a species may sometimes consume numerous prey types, or be consumed by several predators at various trophic levels. To even more accurately describe these interactions, we should use a food web, a chart that demonstrates most the trophic — eating-related — relationships within an ecosystem among different species.
Arrows point from a species consumed on food chains to the creature that consumes it. Some organisms that eat species from more than one trophic stage, as shown in the food web below. Opossum shrimp, for an instance, consume both primary producers as well as primary consumers. Primary producers demonstrated with green, primary consumers with orange, secondary consumers with blue while tertiary consumers with purple.
As one moves through a sensory system from receptors to thalamic nuclei, to primary sensory cortex, to secondary cortex, ..... Represents the thalamic relay between the inferior colliculi and the auditory cortex.
