“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!!”
Answer:
pollen is important in fertilization because pollen carries male gamete and it helps in transportation of male gamete during fertilization in mainly gymnosperms and angiosperms.
I think the enzyme photolyase is activated by light and can repair thymine dimers caused by UV radiation. Exposure to UV radiation is the main factor that causes skin cells to become cancer cells. These enzymes are involved in the repair of ultraviolet light-induced DNA damage when activated by light absorption.
Incomplete dominance refers to a genetic situation in which one allele does not completely dominate another allele, and therefore results in a new phenotype.
Knysna Lourie is naturally found in mature evergreen forests of southern and eastern South Africa, and Swaziland. Although it can vary, and answer of a possible biome can be the Savannahs found in south Africa.
