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)

With a prior history of gunshot wounds in the abdomen S/P multiple abdominal surgeries; the most common complication from this is the formation of adhesions. The formation of adhesions precipitate obstruction of the bowel from partial gut obstruction to complete gut obstruction. The high-pithed, rushing sounds upon auscultation are called borborygmi and this is a hallmark of gut obstruction. This is the sound as the bowels become hyperactive to relieve the obstruction. Eventually, the bowels will become hypoactive.

Why did short plants reappear in mendel’s F2 generation?

Fudgin [204]

Answer:

Because the F1 plants all had a lowercase a/short plant allele, there was a 25% chance that two plants would contribute it to their offspring and they both did sometimes to make a aa offpsring.

Explanation:

All the F1 plants were heterozygous, so when they were crossed, the resulting genotypic ratio was 1 AA : 2 Aa : 1 aa. As you can see, this is the first time since the parent generation that there is a aa genotype and short plant phenotype, so that's why short plants reappeared.
