The relationship between science and technology is that before technologies can exist, there has to be scientific understanding in order to create a technology (option D).
<h3>What is technology?</h3>
Technology is the organization and application of scientific knowledge for practical purposes.
On the other hand, science is the collective discipline of study or learning acquired through the scientific method i.e. the sum of knowledge gained from such methods and discipline.
Technology is the usage of the knowledge of science to create products for human benefit. This suggests that science must come before technology.
Therefore, the relationship between science and technology is that before technologies can exist, there has to be scientific understanding in order to create a technology.

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).
Answer:
The correct answer is c. 3/16.
Explanation:
In the given question two traits being studied, the traits are flower color and seed shape.
This is a typical Mendel’s dihybrid cross. According to the question purple colour (P) and round seed (R) are dominant traits.
When heterozygous purple-flowered (Pp), round-seeded (Rr) individuals are crossed, four different types of plants are produced phenotypically in the ratio 9:3:3:1.Out of 16 offspring, 9 are purple flowered, round seeded pea plants, 3 pea plants are white-flower with round seed, 3 are purple- flower with wrinkled seed and 1 pea plant is white-flowered with wrinkled seed pea plant is produced.
Answer:
d) sedimentary, metamorphic and igneous
Prophase 1, where crossing over occurs and DNA is already replicated
