The solar system is bounded together by gravity, and is made up of the Sun eight planets and dwarf planets
The correct options are;
- The Sun ⇒ generates energy deep in its core through the fusion of hydrogen and into helium
- Earth ⇒ has a single moon that is surprisingly large compared to its planet
- Saturn ⇒ is orbited by at least two geologically active moons: Titan and Enceladus
- Neptune ⇒ has a large moon, Triton, that almost certainly once orbited the Sun independently
- Venus ⇒ has a surface hot enough to melt led as a result of extremely strong greenhouse effect
- Uranus ⇒ has an axis tilt that gives it very extreme seasons
- Pluto ⇒ was studied up close in 2015 by the New Horizons spacecraft.
- Mars ⇒has no surface liquid water today, but shows clear evidence of such water in the distant past
- Jupiter ⇒ has a famous storm known as the Great Red Spot
- Eris ⇒ is similar in size to Pluto and also considered a dwarf planet
- Mercury ⇒ has a greater difference in temperature between its day and night sides than any other world
Reasons:
The Sun generates energy by nuclear fusion in its cores
The size of the Moon more than a quarter of the Earth's size
Saturn moon Titan shows signs of volcanic activity
The moon Triton rotates in the opposite direction to the rotation of Neptune
Venus is the second closest planet to the Sun with a thick CO₂ atmosphere, resulting in a greenhouse effect that makes the planet 510°C hotter
Uranus has seasons that last for approximately 20 years
The New Horizons spacecraft took 9.5 years to reach Pluto after the mission was launched in 2006
Mars liquid water disappeared billions of years ago
The Great Red Spot storm has lasted for over 300 year
Eris, one of the largest dwarf planets and is further from the Sun than Pluto
The difference in temperature between the day and night sides of Mercury is 427°C - (-180°C) ≈ 607°C

<u>The answer to your question is going to be option "D."</u>
Oxygen levels first rose in the atmosphere because of (the last option, or "D') cyanobacteria. Cyanobacteria is a type of bacteria that can create toxins that are very dangerous to both humans and animals.
I hope this helps! :)
<u>Answer:</u> The density of boat is 
<u>Explanation:</u>
To calculate the volume of boat, we use the equation:
where,
V = volume of boat
l = length of boat = 2.00 cm
b = breadth of boat = 11.0 cm
h = height of boat = 11.0 cm
Putting values in above equation, we get:
- To calculate density of a substance, we use the equation:
We are given:
Mass of boat = 213 g
Volume of boat = 
Putting values in above equation, we get:
Hence, the density of boat is
Answer:
In the oxidation of glucose, carbon dioxide and water are formed. As new products are formed of different composition and characteristics, the respiration is considered as a chemical change.
Explanation:
hope that works
Answer: 3m/s^2
Explanation:
Given that:
Acceleration of object = ?
Force = 9 N
Mass of object = 3 kg
Since force is the product of the mass of an object and the acceleration by which it moves i.e Force = mass x acceleration
9N = 3kg x acceleration
Acceleration = 9N/3kg
Acceleration = 3m/s^2 (3 metres per second square)
Thus, an acceleration of 3m/s^2 is produced.
