When using the scientific method, what do scientists do immediately after observing and wondering about the cause of some unexplained phenomenon?

A probability value of less that 1%
is considered to be highly significant

If the frequency of the recessive allele is .3, what is the recessive phenotype frequency (assuming population at genetic equilibrium)?
.09

A probability value of 0.05 means that
there is a 5% (or less) probability of the null hypothesis (that the deviations are due to chance alone).

If there are 3 possible outcomes in a study, how many degrees of freedom are there?
2

Using a compound light microscope, individual chromosomes can be seen
only when cells are dividing

When using the scientific method, what do scientists do immediately after observing and wondering about the cause of some unexplained phenomenon?
check the scientific journals to see what is already known about the phenomenon.
literature survey

Data analysis is part of
testing hypothesis
an experiment

In spite of the chemical variation of the cell walls among Eukaryotes, the function is the same. What is the function?
to prevent the cell from rupturing

What organelle is generally most noticeable when viewing Eukaryotic cells under a microscope?
nucleus

A structure known as a mastax is found in
Rotifera

Amoeba move by means of
pseudopodia

How do scientists communicate the results of their experiments to other scientists?
publishing reports in scientific journals
giving lecture presentations at scientific meetings

What happens during data analysis?
comparison of measurements
see if experimental group data is different from control group data

If the data from an experiment is consistent with the hypothesis
the hypothesis may be true
the data supports the hypothesis

If the data from a thorough experiment shows that the experimental group behaved the same as the control group
the hypothesis is discarded
the hypothesis is false

If an experiment is repeated several times and the results are inconsistent
it's a sign that there may be confounding factors
we can't tell if data supports the hypothesis or not

Why do objects weigh less when submerged in water?
the weight of the displaced water opposes (and reduces) the objects' gravitational force
they displace water when submerged
