Answer:
The correct option is B. A hypothesis
Explanation:
Scientific method can be described as a method following which all scientific researches are made. The scientific method begins with a question. To answer this question, a hypothesis is derived.
A hypothesis can be described as a statement based on which observations are made end experiments are done. A hypothesis is a tentative statement. As the student in the question writes a tentative statement in his/her journal, hence it is most likely to be a hypothesis.
For the first 2 rows it’s going to be the dominant phenotype. So “purple flowers” for the 1st and 2nd row and white flowers for the last one. For the first row on #17 it’s going to be “FF “and “ff” for the 2nd. Tongue roller is “TT” and non tongue roller is “tt.”
Answer: In a simple sense, growth in population is a good thing as it means that a species is thriving and doing well in its environment as well as reproducing at desirable rates. However, if population continues and continues to grow it will eventually reach a cap where an environment can no longer hold more members of that specific species because there is a limit on food and places of shelter. This leads to natural rises and declines in a species over time (which can be very predictable as well.) A downside to rapid and sustained population growth is that if a species keeps growing and growing without reaching its cap (which happens a lot with introduced species into an environment which were not there naturally) is that they can overrun and destroy a natural environment and damage the ecosystem. Animals and species which are already there can have their population numbers drastically reduced because of this invasive species and may be forced to move to a new area.
No, it's because the gases are being heated. Gases expand when heated, and that's what you'd be seeing.
Answer:
= 
Explanation:
Given that the woman’s maternal grandfather is color-blind, then it is possible that the woman is a carrier of color-blind allele.
Then probability that the woman is a carrier of color-blind allele is = 
So if a carrier woman cross with a normal man
Let say the gene of the carrier woman is: 
and the normal man = 
so if we have a cross between and ; we have:
we can see the offspring to be :
=normal unaffected female
= normal unaffected male
= carrier female for color-blind
= carrier male for color-bind
Then probability that of inheriting defective allele = 
=
Let's not forget that the probability that the woman is a carrier of color-blind allele is =
∴ the probability that the son is colorblind = 
=
