Correct Answer: D. 12 ways

Explanation

(a)(i) Median = \(\frac{1}{2} (N + 1)\)

= \(\frac{1}{2}(30 + 1) = 15.5\)

= 15th and 16th position

= \(\frac{2 + 2}{2} = 2\)

(ii) Mean = \(\frac{\sum fx}{\sum f}\)

= \(\frac{84}{30}\)

= \(2.8 \approxeq 3\) (nearest whole no).

(b)

Correct Answer: A. all the actors

Correct Answer: C. Temperate grassland

Correct Answer: B. To show that he came to call the sinners to repentance

Correct Answer: B) Pollination

Explanation

If you remove the petals of a flowering plant, it is likely to affect the process of pollination. Pollination is the transfer of pollen from the male part of a flower to the female part, which results in the fertilization of the ovules and the production of seeds. The petals of a flower play an important role in attracting pollinators, such as bees, butterflies, and birds, to the flower. These pollinators are attracted to the bright colors and sweet smells of the petals, and as they land on the flower to collect nectar, they inadvertently transfer pollen from one flower to another. If the petals are removed, the flower may not be as attractive to pollinators, and therefore, pollination may not occur as effectively. This can have negative consequences for the plant, as it may result in reduced seed production and genetic diversity. It is important to note that removing the petals of a flower may not completely prevent pollination, as other factors, such as wind and water, can also play a role in the transfer of pollen. The other options listed in the question - transpiration, germination, and photosynthesis - are not likely to be affected by the removal of petals. Transpiration is the process by which plants lose water through small openings in their leaves, and this is not directly related to the presence or absence of petals. Germination is the process by which a seed grows into a new plant, and this is also not affected by the removal of petals. Photosynthesis is the process by which plants use sunlight to produce food, and while petals can contribute to this process by absorbing light, their removal is not likely to have a significant impact on overall photosynthesis. In summary, if the petals of a flowering plant are removed, it is likely to affect the process of pollination, which can have negative consequences for the plant's reproduction.
