Consider the following passage. Plant leaves are organs that are composed of multiple cell types, including palisade cells and
guard cells. Palisade cells contain many chloroplasts and are the main sites of photosynthesis in
a leaf. Guard cells are specialized epidermal cells that can change shape in order to control gas
exchange between the leaf and its surroundings.
Which claim is best supported by evidence provided in the passage?
Choose 1
A leaf is primarily made up of one cell type, which allows it to carry out the process of
photosynthesis.
B
Palisade and guard cells each have the capacity to carry out all the functions of the leaf.
independently.
The various cell types found in a leaf have unique, specialized functions.

This problem has been solved! see the answeryou are investigating two traits in fruit flies controlled by one gene each. the b gene controls for body color (black or brown), while the r gene controls for body sculpture (rugose or smooth). after crossing rugose black flies with smooth brown flies, you obtain an f1 generation of 100% smooth black flies. what are the dominant alleles? (1 pt)what are the genotypes of the two parent flies to perform a dihybrid test cross? (1 pt)after running a dihybrid test cross, you find 1000 offspring with the following phenotypes: , rugose406black, smooth86brown, rugose94brown, smooth4141000fill in the expected column with the expected number of offspring in each class of phenotypes. (1 pt)what phenotype classes represent the recombinant offspring? (1 pt each)calculate the relative genetic distance between the body color gene and the body sculpting gene (show your work). (1 pt).
