Answer:
The micrographs of cells shown in figure 8-3. what information about cells do these micrographs suggest is explained below in details.
Explanation:
Micrographs are the intensified images collected from small microscopes. Cell micrographs are often obtained from tissue specimens and show a constant mass of cells and inside compositions that are difficult to distinguish individually. It provides accurate images of the exteriors of cells and whole plants that are not imaginable by TEM. It can also be practiced for particle counting and size resolution, and method control.
The fossils from
Australopithecus provide evidence for evolution because some parts of the bone
that contains the DNA of it can be identified as this type of animal. They can
be detected through the use of carbon dating devices.
The correct answer is 9:3:3:1
When two homozygotes for two traits cross, the phenotypic ratio of the offspring is 9:3:3:1 ( unless other factors like epistatic interaction change the inheritance model).
In our case, we have two simple traits of seed color and seed shape that follow the Mendelian model of inheritance.
In this dihybrid cross, we have
9/16 of the offspring expressing both dominant traits ( yellow and round seeds)
3/16 expressing one dominant and one recessive trait ( yellow and wrinkled)
3/16 expressing the other dominant and recessive trait (green and round)
1/16 expressing both recessive traits ( green and wrinkled)
I believe the answer is C. E. And F.
