Answer:
The correct answer will be- the color change will be observed and the solution will turn purplish-black.
Explanation:
Iodine test is performed to test the presence of the carbohydrates mainly starch.
The iodine solution is chemically called potassium iodide which forms a yellow solution. The potassium iodide solution forms a complex with a starch solution which appears a purplish-black color which shows the presence of the carbohydrates.
In the given question, if we add the iodine solution to the beaker after a certain point of time then it will still form a complex with the starch and thus beaker solution will appear darker in color.
Best Answer: Well, you have to look at the onion slide under the microscope and looks at each cell and tell what stage (interphase, prophase, etc.) they are in. and then for the description probably tell which one there is the most of and maybe why you think that is. You can find pictures of each phase in your book. I did a lab like this not too long ago in my bio class lol. And, i believe that you will get a lot in interphase (when cells are not currently dividing), just to let you know.
Answer:
Bb, Db
, Bd and Dd
Explanation:
When a cross between two parents (having certain trait) is carried out , they share their alleles with each other to produce offspring with new traits. These offspring have gentically different allele combination as compared to their parents. A genetic cross can be represented by a punnet square (as given below)
The cross between two parents with genotype "BD" and "bd" will result into the following offspring -
B D
b Bb Db
d Bd Dd
Answer:
I am willing to be wrong, but based on my understanding of forces it is the pineapple and the baseball
Explanation:
The pineapple has unbalanced forces between gravity and the table
The baseball has unbalanced forces with the propulsion used to move it forward
It may also be the bird but I understood that as net flight force between gravity and lift
