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:
C) electromagnetic waves must have a medium in which to travel, but sound waves can travel anywhere.
Explanation:
Electromagnetic waves do not require a medium to travel. they can travel through vacuum also. for example:- light wave is an electromagnetic wave and it can travel through vacuum also.
On the other hand, sound wave require a medium to travel. sound waves can not travel through vacuum.

Answer:
It would contain four electrons.
Explanation:
A neutral atom has equal numbers of protons and electrons. Therefore, a neutral atom with four protons will also have four electrons.
FYI an atom with four protons is an atom of the element beryllium, Be.
