Answer:
Double fertilization produces a diploid sporophyte and a triploid endosperm. (Ans. C)
Explanation:
Angiosperm are plants which is known for flowering plant on the earth. The flower is reproductive parts of the angiosperm plant. They are including 4 basic parts of the flower: Carpel, Stamens, Sepals and Petals.
During angiosperm plant reproduction, 2 structure are formed which are known as the Endosperm and a Zygote. Later a Zygote will grow and form a embryo and the endosperm is known for food source of plant embryo. Endosperm and Zygote forming process is known as double fertilization and it is a unique process found in angiosperms.
Steps involved in double fertilization are:
1) The pollen tube processing to release 2 sperm cells into an unfertilized ovule.
2) When one sperm cell fuses with the eggs to the formation of zygote and another sperm fuses with the 2 polar nuclei to the formation of endosperm this process is known as double fertilization.
3) After the completion of double fertilization, a fruit and seed develop.
Answer:
Some similarities: they both contain water: ocean in a liquid form and atmosphere as water vapor and oxygen, although oceans have relatively little oxygen (but enough for the fish to catch).
Major difference is that the main substance in the atmosphere is various gasses, while the main substance in the ocean is water in liquid form.

Lighting is seen when there is static buildup from our atmosphere and the ground. Lightning is the static discharge.
Interstate 95 seem to follow the fall line because it was designed to go around rapids and waterfalls
Explanation:
The extreme side of the coastal plain of Virginia that has a chain of rapids and falls as its mark and which has rivers flowing around it is remarkably known as – Fall line. This observation was performed by John Smith first. This line has remarkable impact on Virginian geology.
The line of falls around it prevented the way of ships and led to the formations of some cities of Virginia. The connecting line of major cities of east coast, the Interstate 95 runs parallel to the fall line. This actually seems that it follows the fall line.
