Answer:
THE INNER PLANETS
Mercury, Venus, Earth and Mars
THE OUTER PLANETS
Jupiter, Saturn, Uranus and Neptune
Small size
Earth is the largest of the Inner Planets, with a diameter of 12,756 km (7,926 miles). Mercury is the smallest with a diameter of 4,878 km (3,031 miles)
Huge!
Jupiter, the largest planet, has a diameter of 142,984 km (88,846 miles). Neptune is the smallest of the Outer Planets with a diameter of 49,532 km (30,779 miles)
Have solid surfaces and thin/no atmospheres
In theory, it would be possible to stand on each of the Inner Planets, although you would only survive on Earth.
Balls of gas with no surface
Most of the Outer Planets are made of gas. It is likely that they have a much smaller solid or liquid centre. It would be impossible to stand on any of the Outer Planets.
Greater Density
The size and composition of the planets is caused by the density of the elements that make up the planets. The elements in the Inner Planets are more closely packed together, causing them to be smaller and solid.
Smaller Density
Despite being larger, the elements that make up the Outer Planets are less densely packed together causing them to be quite light for their size.
Varied atmospheres
The contents of the atmospheres of the Inner Planets varies from planet to planet. Mercury has no atmosphere although Sodium and Helium can be detected above the surface. Venus' atmosphere is mostly Carbon Dioxide with a very small amount of Nitrogen. Earth's atmosphere is mostly Nitrogen with a smaller amount of Oxygen and even smaller amounts of other gases. Mars has a similar composition of carbon dioxide and nitrogen as Venus although has a much thinner atmosphere.
Similar atmospheres
The atmospheres of the Outer Planets consist mostly of Hydrogen and Helium, with Methane also being present in the atmospheres of Uranus and Neptune. Other gases are present although in much smaller quantities.
Known by the ancients
The existence of the Inner Planets has been known about for thousands of years. The earliest astronomers didn't know that the four objects (including Earth) were planets, but they knew they existed.
Not known by the ancients
Of the Outer Planets, only Jupiter and Saturn were observed by ancient astronomers. The existence of Uranus and Neptune was not known until relatively recently. Uranus was discovered in 1781 and Neptune in 1846.
Spin slowly
Compared to the much larger Outer Planets, the Inner Planets spin quite slowly. Earth spins the quickest, taking 23 hours and 56 minutes to spin on its axis. Venus takes 243 days to spin on its axis, spinning in an opposite direction to the other planets.
Spin quickly
All of the Outer Planets spin quicker than the Inner Planets. Uranus spins slowest, taking 17 hours and 14 minutes to spin on its axis. Jupiter takes only 9 hours and 55 minutes to spin on its axis. This rapid rotation causes Jupiter and Saturn to appear squashed, wider across the equator than from top to bottom.
Orbit the Sun quickly
Because they are quite close to the Sun, the Inner Planets complete an orbit quickly. Mercury takes only 88 days to orbit the Sun. Mars takes 687 days.
Orbit the Sun slowly
The Outer Planets orbit the Sun from millions of miles and have a much greater distance to cover to complete an orbit, so take much longer to do so. Jupiter takes almost 12 years to complete an orbit and Neptune takes over 164 years.
Few Moons
Only Earth and Mars have moons orbiting them. One moon orbits Earth and two small moons orbit Mars.
Lots of Moons
All of the Outer Planets have many moons orbiting them. There are 63 moons known to orbit Jupiter, 60 orbiting Saturn, 27 orbiting Uranus and 13 orbiting Neptune.
No rings
None of the Inner Planets have rings orbiting them
Rings
All of the Outer Planets have rings orbiting them. The rings are thin discs of dust and rocks possibly caused by moons being broken up or not being completely formed while orbiting the planet. Saturn has the most visible ring system of any of the planets.
Multiple space craft visitors
Due to being close to Earth, there have been several missions to the other Inner Planets, especially to Mars and Venus. Mercury has been visited by two spacecrafts.
All Outer Planets visited by one space craft
There have been multiple visits to Jupiter and Saturn, but Uranus and Neptune have only been visited once. This was by Voyager 2 (which also visited Jupiter and Saturn).

Which characteristics do birds and mammals share? Check all that apply.
Both give birth to live young.
Both are endotherms.
Both have hair or fur.
Both produce milk to feed their young.
Both are vertebrates.
Answer:
Extant birds and mammals share a number of highly similar characteristics, including but not limited to, enhanced hearing, vocal communication, endothermy, insulation, shivering, respiratory turbinates, high basal metabolism, grinding, sustained activity, four-chambered heart, high blood pressure, and intensive ...
An endotherm is an organism that uses internal body heat to maintain a metabolically suitable temperature rather than relying on ambient heat. The endotherms primarily include the birds and mammals.
Why are birds and mammals endotherm?In contrast to organisms that rely on the heat of their surroundings to sustain a temperature that is optimal for their metabolic processes, endotherms generate their own heat from within their bodies. The majority of endotherms are comprised of different kinds of birds and animals.
Endotherms, which include birds and mammals, generate and store a significant amount of heat within their own tissues, as opposed to ectotherms, which include insects and reptiles, who take in heat from their surroundings. Insects and reptiles are examples of ectotherms.

These are called multiallelic traits. If GGHHII was crossed with gghhii, what would the genotype for every offspring be?
a. ggGGhhHHIIii
b. GGhHII
c. GgHhIi
d. ggHHii
Answer:
In the crossing of individuals with multiallelic traits, the crossing of a GGHHII individual with a gghhii individual would produce offspring of hybrid individuals for all three traits whose genotype would be GgHhIi (option c).
Explanation:
The individuals GGHHII and gghhii are pure lines for each of the traits —multiallelic traits— they express, one of them having the three dominant traits and the other three recessive traits. The product of crossing two pure lines with dominant and recessive traits is an offspring of 100% heterozygous individuals.
This can be tested by making a Punnett square for this cross:
GGHHII X gghhii
Alleles GHI GHI
ghi GgHhIi GgHhIi
ghi GgHhIi GgHhIi
Thus the offspring in the cross of two individuals, dominant and recessive, for multiallelic traits G, H and I is GgHhIi

According to the base-pairing rules for DNA, which of the following statements
NOT true?
A always pairs with T
C always pairs with G
T always pairs with G
T always pairs with A
Answer:
T always pairs with A
Explanation:
I think so I'm super sorry if its wrong :)
According to the base pairing rule, guanine always forms a bond with cytosine, while adenine always pairs with thymine, T is not paired with G, hence option C is correct.
What is base-pairing in DNA?Because it is RNA, there is no complementary base pairing between the bases adenine and thymine in DNA. Uracil, which has a structure remarkably similar to that of thymine, is present in place of thymine.
Base pairing rule, guanine always forms a bond with cytosine, while adenine always pairs with thymine structure of DNA is created by the binding of these base pairs
Although they keep the two strands of DNA together, they are not strong enough to withstand replication.
Therefore, the base pairing rule, guanine always forms a bond with cytosine, while adenine always pairs with thymine, hence option C is correct.

is the mass of wood charcoal and oxygen the same before and after the fire ?
Answer:
Here u go I even looked it up for u ;)
The law of conservation of mass was created in 1789 by a French chemist, Antoine Lavoisier. ... For example, when wood burns, the mass of the soot, ashes, and gases, equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant
A 200g ball begins falling from a height of 15m. If the (a) acceleration due to gravity is 10 m/s^2. How long do you calculate it will be before the object reaches the ground? Which formula will you use?
Answer:
1.732 seconds
[tex]s=ut+\dfrac{1}{2}at^2[/tex]
Explanation:
s = Displacement of ball = 15 m
g = a = Acceleration due to gravity = [tex]10\ \text{m/s}^2[/tex]
u = Initial velocity of the ball = 0
t = Time taken
From the kinematic equations we use the following formula
[tex]s=ut+\dfrac{1}{2}at^2\\\Rightarrow 15=0t+\dfrac{1}{2}\times 10t^2\\\Rightarrow t=\sqrt{\dfrac{15\times 2}{10}}\\\Rightarrow t=\sqrt{3}=1.732\ \text{s}[/tex]
The object will reach the ground after 1.732 seconds.
The formula used is [tex]s=ut+\dfrac{1}{2}at^2[/tex].

Explain what the greenhouse effect is, use diagrams if you wish.
Include:
-Radiation from the sun absorbs earths heat
-Some emitted
-Trapped by the greenhouse
Answer:
See the answer below
Explanation:
The greenhouse effect refers to the heating effects produced by the earth's atmosphere on the planet as a result of the atmosphere absorbing reflected radiation from the sun by the earth.
The earth's atmosphere is a blanket of gases, some of which are referred to as greenhouse gases. These gases have the capacity to trap radiations coming from the sun that is reflected by the ground layer of the earth. Thus, they produce a warming effect on the earth.
A bulk of the radiation coming from the sun is reflected back into space by the earth's stratosphere. The small percentage that passes through are dispersed in different directions and some of them pass through the atmospheric blanket to reach the ground layer of the earth. While some are absorbed by the ground itself, some are emitted back into the atmosphere where the greenhouse gases trap a large portion and prevent them from escaping back into space.
This leads to the warming of the earth and the entire phenomenon is referred to as the greenhouse effect.

Which of these factors affects how fast a sound wave moves? the kind of material it is moving through the kind of material it is moving through the amplitude of the sound wave's vibrations the amplitude of the sound wave's vibrations the wavelength of the disturbance in the medium the wavelength of the disturbance in the medium the type of motion that caused the sound wave to form the type of motion that caused the sound wave to form
Answer:
the kind of material it is moving through
Explanation:
Sound wave is a type of mechanical wave, which requires a medium to travel, unlike longitudinal waves that can travel through vacuums. Since, sound waves travel through mediums, the KIND OF MEDIUM/MATERIAL it is traveling through has a role to play on how fast it moves.
Sound waves move faster in materials whose molecules are closely packed together than those with loosely packed molecules. This is why sound waves naturally travel faster in SOLID materials. Therefore, the the kind of material the sound wave is moving through affects how fast it moves.
