C. 1,2,1,2

1 CH4+ 2 O2= 1 CO2+ 2 H20.

when balancing, you need to make sure that each side has the same number of each atom. The reason for this is to abide by the law of conservation of mass; essentially you can't have more or less than you put in the equation.

When you put the coefficients of C. into the equation you have a total of 2 carbon atoms on each side, 4 hydrogen atoms, and 4 oxygen atoms.

kkurt [141]

<h2>Answer:</h2><h3>Part 1.</h3><h3> Celestial body A is the largest planet in the solar system.</h3>

It is Jupiter which is a <u>Gas giants.</u>

Jupiter is mostly made of gas.

According to above statement, It is the Jupiter which largest planet in our solar system. Jupiter's mass is more than 300 times that of Earth, and its diameter, d, at 140,000 km.

<h3>Part 2. </h3><h3>Celestial body C has optimum conditions to sustain life.</h3>

It is earth which is a<u> terrestrial planet.</u>
Because it is mostly made of silicate rocks and minerals.

According to statement, earth is that planet because it has living optimum conditions. Like the oxygen concentration, water, plants etc.

Celestial body E has the most volcanoes in our solar system apart from earth. It is the second closest planet to the sun.

It is Venus and it is a<u> terrestrial planet.</u>

Venus orbits sun every 224.7 Earth days.

It has the longest rotation period of any planet and it rotates in opposite direction to most of the planets in the Solar System.

<h3>Part 4.</h3><h3>Celestial body H is the second largest planet in the solar system and has visible rings.</h3>

It is Saturn which is a <u>gas giant.</u>
Because it is mostly consists of gases and it also has ring of gases around itself.

it is 9.4 times as large as the Earth. It also has a large and bright ring system.

<h3>Part 5.</h3><h3>Celestial body D has 17 times more mass than earth and has gravity that is 1.14 times that of earth. </h3>

It is Neptune and it is a <u>gas giant</u>.
It has mostly gaseous composition, such as hydrogen and helium.

Neptune is the eighth and farthest known planet of the Solar System. It is also the third most massive planet.

<h3>Part 6.</h3><h3>Celestial body G has a core that consists of iron sulfide mixed with nickel and is the second smallest planet in the solar system.</h3>

It is mars and it is a<u> terrestrial planet</u>.
Mars is the second smallest planet while mercury is first smallest planet after the exclusion of Pluto from solar system.

The surface of mars is covered by talcum powder type dust. It contains elements besides silicon and oxygen, are iron, magnesium, aluminum, calcium, and potassium.

<h3>Part 7.</h3><h3>Celestial body I had a core composed of nickel iron alloy rock surrounded by an outer layer of hot fluid. The fluid contains water, ammonia, and methane body I has 27 moons .</h3>

This is Uranus and it is a<u> gas giant</u>.
is the seventh planet of the Solar System.

According to radius, it is on third number and according to mass it is forth largest planet. Its composition is more similar to Neptune.

Scientists have discovered and analyzed a huge number of fossils that represent a wide variety of species. What type of evidence

Rainbow [258]

Answer:

The fossil record supports a "biological" type of evidence.

Explanation:

<u>Fossils-</u> this refers to the <em>remains of prehistoric organism.</em><em> </em>It provides a trace of a <em><u>once-living plant, animal or organism. </u></em>

When it comes to evolution, fossils provide a biological type of evidence. This means that,<u><em> it shows how organism have greatly changed from the past.</em></u> When you study fossil records, you can compare it with the animal, plant or human structure nowadays. You can compare them side-by-side. So, you'd get that idea on how prehistoric things lived in the past and how they evolved up to the present day or became extinct.

<em>Most of the fossils can be found on sedimentary rocks.</em> You can also tell their ages according to which layer they belong. It is said that older layers consist of older fossils and they appear at the bottom while younger layers consist of younger fossils and they appear on top.
