Answer: The theory of cheek cells is used for the identification of cheek cells.
Explanation:
The cells of cheek do not have cell wall. They have a cell membrane which allows on certain molecules to pass through it. The nucleus is located centrally in the cheek cells and it stores the DNA. It can be stained with the help of the methylene blue reagent. It appears blue in color which can be observed under the microscope. The cheek cells can be isolated from the buccal cavity by using cotton buds and cotton swabs can help in isolating the cells.
Answer:
cells that should not invade other tissues do invade other tissues
Explanation:
The answer could be any of the following:
* energy
* sugar
* carbohydrates
* (possibly even) food.
Answer: Major grain crops are corn, wheat, barley, oats, rye, rice, sorghum, and soybeans. Less than 10 percent of the corn grown in the U.S. is for human consumption. Legume plants such as dry beans and peas are important foods in the diet of many Americans and people around the world.
Explanation:
Answer:
3:1
Explanation:
To find out the phenotypic ratio, we need to do a Punnet Square.
We know that R and I are the dominant alleles that produce red flowers, and r and i are the recessive traits.
<u> ║R ║ r</u>
<u>I ║RI║Ir</u>
<u>i ║Ri║ir</u>
The genotype ratio would be 3 because the dominant traits are present three times (RI, Ir, and Ri) and 1 for the recessive trait since it only appears once in the Punnet Square (ir). In conclusion, the phenotypic ratio form the roses are 3:1
