Solar System[a] is the gravitationallybound system of the Sun and the objects that orbit it, either directly or indirectly,[b] including the eight planets and five dwarf planets as defined by the International Astronomical Union (IAU). Of the objects that orbit the Sun directly, the largest eight are the planets,[c]with the remainder being smaller objects, such as dwarf planets and small Solar System bodies. Of the objects that orbit the Sun indirectly—the moons—two are larger than the smallest planet, Mercury.[d]

The Solar System formed 4.6 billion years agofrom the gravitational collapse of a giant interstellar molecular cloud. The vast majority of the system's mass is in the Sun, with the majority of the remaining mass contained in Jupiter. The four smaller inner planets, Mercury, Venus, Earth and Mars, are terrestrial planets, being primarily composed of rock and metal. The four outer planets are giant planets, being substantially more massive than the terrestrials. The two largest, Jupiterand Saturn, are gas giants, being composed mainly of hydrogen and helium; the two outermost planets, Uranus and Neptune, are ice giants, being composed mostly of substances with relatively high melting points compared with hydrogen and helium, called volatiles, such as water, ammonia and methane. All eight planets have almost circular orbits that lie within a nearly flat disc called the ecliptic.
Cell is our microscopic structure. We have Trillions of cells in our body, which plays very important roll. Our every tissue, organ, organ system, our whole body has composed of cells. In order to make a nice and informed decision for our health, we must need to understand our body at cellular level
Hope this helps!

Explanation:
Given parameters:
Energy required to break one C-H bond = 98.8kcals
Unknown:
Energy required to break methane = ?
Solution:
The bond dissociation energy is the heat energy absorbed in breaking a covalent bond in the gas phase to its constituents elements.
Solving
CH₄ has 4 C-H bonds
To break 1 C-H bond, 98.8kcals of energy was used,
To break 4 of the bonds; 4 x 98.8kcals will be used = 395.2kcal

The following vessels are connected as below:
aorta ->renal arteries ->segmental arteries ->interlobular arteries ->arcuate arteries ->cortical radiata ->afferent arteries ->glomerulus.
1) aorta : arises from heart which carry blood from heart to the rest of the body
2) renal artery :it arises from the aorta which carry blood to kidney .it carry unfiltered blood .
3)segmental arteries : it arises from renal artery .it has 5 branches or segments.
4)interlobular arteries : it arises from segmental arteries. the interlobular arteries pass directly outward between the medullary rays to reach the fibrous tunic ,where they end in the capillary network of this part.
5)Arcuate arteries: it arises from interlobular arteries .it is also known as arciform arteries, are vessels of the renal circulation. they are located at the border of the renal cortex and renal medulla.
6) cortical radiata: it arises from arcuate arteries.
7) afferent arteries: it arises from interlobular arteries and also connects to glomerulus. they are a group of blood vessels that supply the nephrons in many excretory systems .they play a important role in regulation of blood vessels.
8) glomerulus : it connects from afferent arteries.it is the filtering unit of kidney ,is a specialised bundle of capillaries that are uniquely situated between two resistance vessels.
