Answer:
Plant cell has larger vacuoles.
Explanation:
Vacuole is a fluid filled structure found in cells of the plants, certain animals, protists, fungi, bacteria etc. Vacuoles found in plant cells are larger than that in animal, protist, fungal, and bacterial cells. The vacuole inside a plant cell stores water. It also helps to maintain the turgor pressure of the cell. The functions of the vacuole include isolating materials that might be harmful to the cell
, maintaining an acidic internal pH
, supporting the plant structures such as leaves and flowers.
Answer:
RFLP analysis.
Explanation:
RFLP (Restriction fragment length polymorphism ) may be defined as a molecular technique used to determine the location of a particular gene in the DNA sequences. The individuals among the population can be easily identified by RFLP analysis.
The restriction enzyme is used for the digestion of DNA sample. The restriction fragments are then visualized by running the fragments on gel electrophoresis. The hybridization between single stranded nucleic acid is not involved in the RFLP.
Thus, the correct answer is option (1).

The 117th Christmas Bird Count is now over. As usual in January, I will discuss the highlights of some of the Maine counts. These standardized censuses provide an important tool to monitor the abundance of winter birds throughout North America and beyond.
I’ll concentrate on changes in regularly wintering birds, the arrival of unpredictable invaders and records of lingering birds whose wintering areas are well to our south. A rarity or two may pop up as well.
We’ll start with the southern Maine coast. The York County count was held on Dec. 21. Thirty observers found 82 species of birds.
