Answer:
The correct answer is A) differentiated cells retain all the genes of the zygote
Explanation:
A plant can be cloned from the somatic cells which shows that the differentiated cell of plants have the ability to divide and differentiate to produce a new plant. This property of the cell is called totipotency.
All the cells in plants are not totipotent but some cells under proper condition can show the property of totipotency. Totipotency property shows that the differentiated cell is having all the genes that were present in the zygote.
This property of plant cells is used by scientist in plant tissue culture to produce plants for research and other purposes. So the right answer is A.
Answer:
0.05 mg/mL ( B )
Explanation:
Given data:
20 mg/ml starch
2% solution = 2g of solute is in 100g of solvent
<u>Determine the new concentration in mg/ml </u>
Dilution equation = C1V1 = C2V2
new concentration ; applying the dilution factor
dilution factor = 1 : 400 ; ( 2 /400 )g = 0.005 g of solute is present in every 100 mL
∴ new concentration = 0.00005 g / 1 mL * ( 1000 mg / 1g ) = 0.05 mg/mL
The answer is B. gibberellins

Most sponge body plans are slight variations on a simple tube-within-a-tube design. which of the following is a key limitation of sponge body plans? sponges lack the specialized cell types needed to produce more complex body plans. the reliance on osmosis/diffusion requires a design that maximizes the surface area to volume ratio of the sponge. choanocytes must be protected from the hostile exterior environment. spongin cannot support heavy bodies.
