in South American plantations also failed. In both cases, the trees grew vigorously, produced healthy flowers in profusion, but set no fruit. Consequently, what is the likely source of the problem?
A) poor sporophyte fertility
B) failure to produce fertile ovules
C) failure to produce pollen
D) pollination failure

Answer:

D) pollination failure

Explanation:

Pollination failure can be caused by several factors which limit the chances of pollen being transferred to the stigmas, and/or prevents forming of fruits. In the nut trees, as a result of the self-incompatible flowers which limit the number of pollinators to only orchid bees, pollination failure is the most likely source of the problem why fruits don’t set. The selective nature of the nut flowers reduces the numbers of pollinators.

How to find the formula for the nth term​
snow_tiger [21]
“The nth term of the following types of sequences can be found out using the following Formulas:

1.Arithmetic Progression(AP) : here, the consecutive terms differ by a common difference (d).

tn= a+(n-1)d

Where,

a= is the first term of the sequence,

n= nth term

d= common difference

2. Geometric Progression(GP):

Here, the consequtive terms differ by a common ratio (r).

Tn= ar^(n-1)

where,

a = first term

r = common ratio

tn= nth term

3.Harmonic Progression (H.P):

It is the reciprocal of AP.

To find nth term of a HP, first convert it into AP and then apply the tn formula for the sequence and take the reciprocal of the obtained tn again.

Hope the answer helps you!!”
