Answer:
The dominant (light green) parent was heterozygote for the trait
Explanation:
According to Gregor Mendel in his law of dominance, an allele is said to be DOMINANT if it masks the phenotypic expression of another allele in a gene. The allele being masked is called RECESSIVE allele. In this case of a frog whose allele for light green color is dominant over the allele for brown color, the light green color allele (G) is dominant while the brown color allele (g) is recessive.
However, in a cross between that have light green frog and a brown frog, a small brown frog is produced. This is possible despite the green color being dominant because the genotype of the light green dominant parent is HETEROZYGOUS i.e. it contains both light green (dominant) allele and brown (recessive) allele.
Hence, when a gamete with recessive allele (g) is produced by the heterozygous light green frog (Gg), it mates with a recessive allele from the brown frog (gg) to produce a brown offspring (gg).

Answer:
C. ATP is required to move substance A into the cell.
Explanation:
As the model shows a cell with the movement of substances A and B, so the correct statement following the model is "ATP is required to move substance A into the cell".
This is so because ATP is required by a cell to move the substance such as ions across a membrane against a concentration and at the same time another substance moves out of the cell by the process called diffusion.
<u>As in the model, we can see substance A is moving in the cell while B is moving out of the cell (distance between cell membrane and substance B is more).</u>
Hence, the correct answer is "C. ATP is required to move substance A into the cell."
Answer:
Fossil B belongs to the same period as the trilobite
