Answer:
double fertilization
Explanation:
Flowering plants or angiosperms are seed-producing plants with the ability to produce reproductive organs-flowers and fruits with seed in it (unlike gimnosperms which contain naked seed). Another distinctive feature of angiosperms is their reduced gametophytes. This feature most likely reduces the time between pollination and fertilization. Fertilization in flowerin plants is double, meaning that two sperm cells fertilize ovule cells(egg cell and central nuclei cell): one forms diploid zygote which will develop in embryo, while other form triploid cell which will develop into endosperm (provides nutrition for the embryo).
<span>The
answer is A. The reduction in variety reduces the number of alleles for
each gene in the gene pool. This reduces the variations in the phenotypes of the crops. A disadvantage of this phenomenon is that it
would be difficult for the crops to withstand
environmental changes and calamities because there is no wide variation on
which natural selection could act upon to
enable the crops to adapt to these changes.</span>

From the question given above,
A snickers® candy bar contains
280 calories. Fat content = 120 calories
1 calorie = 4.184 j
120 calories = 120 x 4,184 =
502.08j = 5.0 x 10² KJ
The energy of the fat content is 5.0
x 10² KJ.
