Answer:
95 isoadenine bases; adenine bases cannot be determined
Explanation:
In Alien DNA;
- iA complementary with U
- iT complementary with A
- bG complementary with iC
- So if there were 95 nucleotide that contain the uracil then there should also be 95 isoadenine.
- Adenine binds with isothymine in alien DNA and there are no information of isothymine or other bG/iC bases is given, so we cannot determine the adenine bases.

Answer:
When viewing a specimen in a microscope, what allows to physically see the image are both lenses, eyepiece and objective.
Explanation:
In optical microscopy, the lenses used to observe microscopic samples play an important role and are necessary for the study of such samples.
- An objective lens is the first to capture the image, providing clarity and proper focus, as well as eliminating color or shape distortions.
- Eyepiece lens obtains the image provided by the objective lens and enlarges it, so that the observer can appreciate the characteristics of the specimen studied.
Regarding other options:
- <u><em>Stage</em></u><em> allows to see the prepared sample, ready for its study, but the microscopic characteristics are not appreciated.
</em>
- <em>The </em><u><em>eyepiece and objective</em></u><em> work together to provide a proper microscopic image.</em>
Answer:
E. 6:3:3:2:1:1
Explanation:
Look at the attached picture to see the Punnett square for your problem.
The cross for this is snapdragons who are heterozygous for both traits so the cross would be:
<em>TtRr x TtRr</em>
As you can see in the image, you have the following genotype combinations with the corresponding phenotype combinations:
GENTOTYPE PHENOTYPE NUMBER
TTRR Tall - Red 1
TtRR Tall - Red 2
TTRr Tall - Pink 2
TtRr Tall - Pink 4
TTrr Tall - White 1
Ttrr Tall - White 2
ttRR Short - Red 1
ttRr Short - Pink 2
ttrr Short - White 1
The following phenotype combinations in summary would then be:
Tall - Pink: 6
Tall - Red: 3
Tall - White: 3
Short - Pink: 2
Short - White: 1
Short - Red: 1
So the ratio is 9:3:3:2:1:1
