Explanation:
Please Correct me If I am wrong :)
Answer: D is right
Explanation: It seems both waves have same wavelength.
Because speed = wavelength · frequency (v = λf) and
f = v/λ, so frequency is same. Because period T = 1/ frequency, also periods are same. Wave Y has higher amplidude and its energy is greater.

Answer:
The correct answer is c. detergent is used to break apart plant cells to extract DNA.
Explanation:
Here we are talking about DNA isolation in E.coli and detergent is used to break apart the bacterial cell membrane by destabilizing the cell membrane. Detergent disintegrates the proteins present in the cell membrane which causes the rupture of membrane releasing the cell extract outside the cell.
Detergent is not able to break plant cell because it is made up of cellulose and require blending or mashing. Detergent can only be used to disintegrate the cell membrane because only cell membranes contain lipids and proteins.
Hence, the correct answer is c. detergent is used to break apart plant cells to extract DNA.
When rice is left in a
pan of water overnight it is called soaking of the rice.
<span>Soaking of rice is
used to decrease cooking time, conserve fuel, minimize exposure to high
temperature, and reduce stickiness. For some varieties, it can improve the
texture of the cooked rice. For example, brown rice may be soaked in order to stimulate
germination (germinated brown rice). In this case, soaking activates enzymes
and enhances amino acids to improve the nutritional value of rice.</span>
