Answer:
The diagram is used by biologists to determine the probability of an offspring having a particular genotype. The Punnett square is a tabular summary of possible combinations of maternal alleles with paternal alleles. The Punnett square is a visual representation of Mendelian inheritance.
Explanation:
An example of a Punnett square:
tt and TT
t . t
T tT . tT
T tT tT

Answer:
Casts are cylindrical bodies formed either in the distal convoluted tubules or the collecting ducts of the kidney. Since the walls of the tubule act as a mold for cast formation, the width of the tubule determines the width of the cast.
Explanation:
This is how cast formed.
It is important so that the diffusion distance is shortened so gas exchange occurs more efficient.
As you may already know, lungs are used for gas exchange, and the alveoli is the surface for gas exchange. Gas exchange is where carbon dioxide from the blood capillaries (on the alveoli) are diffused into the alveoli, while the new oxygen that we breathed in are diffused to the capillaries.
Since the whole has exchange process relays on diffusion, so diffusion must happened fast in order to increase the efficiency. Therefore, the alveoli is only one cell thick so carbon dioxide and oxygen has a shorter distance to diffuse through so more of these gas can be exchanged.
Probually the red blood cells choose 3) hope this helps if so mark brainliest
Answer:
D. Use the polymerase chain reaction.
Explanation:
<em>Option A is incorrect because subjecting the DNA to electrophoresis will only identify, purify or quantify the DNA.</em>
<em>Option B is incorrect because nucleic acid probes are only useful in detecting mRNA.</em>
<em>C is incorrect because amniocentesis is just a medical procedure involving the removal of amniotic fluid for the purpose of analysis.</em>
<em>Option E is not correct because restriction enzymes will only cut the DNA at specific points.</em>
The correct option is D. Polymerase chain reaction is a procedure in molecular biology that is utilized to amplify or multiply a copy of DNA.
