Helpful bacteria: Decomposers, Nitrogen fixers, Probiotics
Harmful bacteria: Pathogens, Salmonella, MRSA
Bacteria are microscopic,
single-celled organisms that exist in their millions, in every environment,
both inside and outside other organisms. There are many different types of
bacteria. One way of classifying them is by shape. Some bacteria are helpful
while some are harmful.
This study lacks generalizability.
Generalizability is an academic term and describes the process of extending research findings and observations from a study on a sample population to a larger and more diverse population. The larger the sample population, the easier will be to generalize the results to the wider population. In this example, Dr Kirch used a sampling technique called convenience sampling, which involves the selection of the most available and proximate subjects. However, there is sampling bias since the sampling population is not representative of the entire population and therefore the study can not speak for the entire population.
A scientific Theory is a well-tested explanation for a wide range of observation or experimental results
Answer:
50% of their children will have blond hair
Explanation:
Given ,
Allele for brown hair is represented by "B" and it is a dominant trait
While Allele for blond hair is represented by "b" and it is a recessive trait.
Genotype of Sally when it is given that she carries the recessive gene of blond hair - Bb
Genotype of Sally's husband who has has blond hair, which is a recessive trait - bb
Bb x bb
Bb, Bb, bb, bb
Out of four offspring two will have blonde color hair,
Thus, 50% of their children will have blond hair
They are in the same periods
