Answer:
C
Explanation:
(Humans) body cells and viruses both contain RNA and DNA. So both have this similarity.
Answer: c
Explanation: Plants and animals need nitrogen to make proteins but they cannot take it in from the air. Because nitrogen is unreactive as a gas, it has to be transformed into a new molecule. When bacteria in the soil takes nitrogen from the air, it becomes nitrates. Finally, it can move through the food chain in this form.
Answer:
27 genotypes and 8 phenotypes
Explanation:
Supposing that the genotypes of both of the parents are AaBbDd (A, B and D are dominant over a, b and d). After completing the Punnett square, you can predict the following offspring:
I add an image where you can see all the 27 genotypes and frequencies.
Finally, all the 8 phenotypes with the following frequencies:
27/64 A-B-D-
9/64 A-B-dd
9/64 A-bbD-
9/64 aaB-D-
3/64 A-bbdd
3/64 aaB-dd
3/64 aabbD-
<u>1/64 aabbdd </u>
Total 64/64
Note: when a phenotype is A-, it means that it came from either genotype, AA or Aa. The same applies to B- (BB or Bb) and D- (DD or Dd)
