Answer:
genetic engineering is possible because all organisms are based on the same. genetic code. scientists can study the effect of turning off a gene by using. gene knockout ... a ring of bacterial dna with foreign DNA inserted ... transgenic organisms can express the foreign genes because all organisms are bases on the same.
Explanation:
by studying the parents’ karyotypes
b.
by studying the family’s pedigree chart
c.
by exploring new methods of genetic engineering
d.
by determining whether the parents have codominant alleles
Answer:
The answer is B. By studying the family’s pedigree chart
Explanation:
Cystic fibrosis is an inherited disorder that tends to be fatal, since it damages the lungs and digestive system. Cystic fibrosis affects the cells that produce mucosa, sweat and gastric juices, causing them to become thick and sticky, causing the tubes, tracts and channels to become clogged. It is a hereditary disease, caused by a defective gene (so the best way to predict it would be through studying the family's pedigree chart) that leads the body to produce an abnormally thick and sticky fluid.
Answer:
Wavy haired would be SC, seeing as it is "heterozygous," meaning it has one of each allele. This is called incomplete dominance, where neither allele is expressed fully over the other.
B. Physical change; physical property of flammability
C. Chemical change; chemical property of reactivity
D. Chemical change; chemical property of flammability
Answer:
C = chemical change, chemical property of reactivity.
Explanation:
Chemical change:
The changes, that occur due to change in the composition of a substance and result in a different compound is known as chemical change.
These changes are irreversible
These changes occur due to chemical reactions
These may not be observed with naked eye
Example:
The reaction of iron with air in the presence of water lead to the production if ion oxide which is called rusting. It is a chemical change.
Combustion of fuel or wood: that oil or wood convert into energy, CO2 and ash in case of wood
Boiling of egg: that change the chemical composition of protein in the egg
The reaction of Hydrogen and oxygen:
H 2 (g) + O 2 (g) -------------------------------------> 2H 2O (l)
Physical Change:
The changes that occur only due to change in shape or form but their chemical or internal composition remain unchanged.
These changes were reversible.
They have same chemical property.
These changes can be observed with naked eye.
Example
Water converting to Ice
Water converting to gas
In this water molecule remain the same only they rearrange themselves that change its state of mater not composition
Answer:
C) Chemical Change; Chemical Property of reactivity
Explanation:
I took the test
H2CO3 -> H2O + CO2
Answer:
this is bases
Explanation:
because, acids chemical reaction , there is no 2 written when writing an acids chemical reaction
B. Men and women all over the world have investigated scientific questions throughout history.
C. All useful scientific knowledge has developed within the past 100 years.
D. No new discoveries are left to be made.
A is wrong, because that fact just simply is not true. There have been several other raced men and some women as well that made important contributions to science.
B is correct, because science isn't attributable to just the last couple of hundred years. In ancient times, people developed astronomy and medicine. This is also correct because it names females as part of the scientific contributions to society.
C is incorrect, because this fact is also completely false. Lots of important scientific discoveries have been made from before that, such as the invention of electricity (somewhat useful today I would guess :\ ) in 1879, which is much longer than 100 years ago.
D is also incorrect, because scientific knowledge is changing constantly, every minute, growing and expanding and changing to accomodate new knowledge and information that we've discovered.
Biological science has developed over time through the contributions of both men and women from different backgrounds and cultures.
B. Men and women all over the world have investigated scientific questions throughout history.
Biological science has developed over time through the contributions of both men and women from different backgrounds and cultures. For example, ancient civilizations like the Egyptians and Greeks made significant contributions to biological knowledge, such as the discovery of human anatomy and classification of organisms. This trend of diverse contributions continued throughout history and is still evident today.
By recognizing the contributions of individuals from different genders, races, and cultures, we can appreciate the rich history and ongoing development of biological science.

a. Could any of their children be blood type O? Explain.
Explanation:
Let's reflect on heredity:
Females are birthed when two X chromosomes are paired up (XX).
Males are birthed when one X chromosome and one Y chromosome are paired up (XY).
If the woman has blood type AB and her husband has blood type O, their children could have any blood type associated with that. Try setting up a punnett square!
You will get:
2/4 AO
2/4 BO
So, the odds of a child getting OO are 0.
