The correct answer is 50%, or 1/2. We know that round seeds are dominant, since the round pea plant has a genotype of Rr and the wrinkled pea plant has a genotype of rr. If it helps, draw a Punnett square with the two genotypes.
R r
r
r
The square works exactly like a coordinate grid. Combine the letters above and beside whichever of the four spaces you chose to find the genotype for that space.
R r
r Rr rr
r Rr rr
Therefore, 2 out of 4 of the pea plants have round seeds, since a genotype of Rr means that a plant will have round seeds, and 2 out of 4 will have wrinkled seeds, since a genotype of rr means that a plant will have wrinkled seeds. 2/4 simplifies to 1/2, or 50%. Therefore, there is a 50% chance that the offspring will have wrinkled seeds.
Hope this helps!
Answer: The palpating heart race response is due to the sympathetic nervous system controlling the body's fight-or-flight reactions.
Explanation:
The sympathetic nervous system is in charged of controlling the body's fight-or-flight reactions. When facing a threat, these responses defaultly prepare our body to flee from danger or face the threat head-on.

Answer:
C. The universe coalesced into one solar system after the Big Bang.
Explanation:
This is true because, since she is writing about Big Bang theory, she would have to include how the universe was able to expand to one solar system made up of different planetary bodies. This explanation would help someone reading her writeup to understand what the Big Bang theory is all about.
