Answer and Explanation:
We can assume that being colorblind is a recessive trait.
That means the father has a genotype of both lowercase letters, denoted as bb.
Let's make a chart.
- The Father's Genotype is bb
- The Mother's Genotype is Bb (Because she is heterozygous, which means she has one Dominant trait (B) and one recessive trait (r))
<u> b b </u>
<u>B| Bb | Bb |</u>
<u>b| bb | bb |</u>
We get 50% of the offspring to be colorblind, and 50% of the offspring to have normal color vision.
<u>That means the expected percentage is 50%.</u>
(Don't look too much into the capitalized MALE, its just there to throw you off guard and mess you up)

Answer:
The two main objectives of scientific investigation are knowledge production and hypothesis development. Science uses a wide variety of persons and settings to conduct its investigations. There are numerous methods for conducting scientific research, all of which rely on the collection of various types of data.
Human error can occur when measurements are made improperly or when observations are incorrectly recorded. Scientific fraud is the term for deliberate data manipulation. Bias, or prior conviction that the hypothesis is correct or false, can have an impact on the accuracy of observation and the interpretation of data.
Explanation:
I paraphrased this for you (Not plagiarized).
Mature mammalian red blood cells lack nuclei, mitochondria and rough endoplasmic reticulum, they do not contain DNA and consequently, cannot divide. They also cannot synthesise RNA nor synthesise any new proteins, and consequently, have a limited lifespan. Mature red blood cells circulate for about 100–120 days in the body before they are removed by the spleen.
Hope this helps
