Answer:
The Glossopteris fossil is found in Australia, Antarctica, India, South Africa, and South America—all the southern continents. Now, the Glossopteris seed is known to be large and bulky and therefore could not have drifted or flown across the oceans to a separate continent

Your welcome
Answer:
Rhodium-122 < Palladium-109 < Silver-109 < Cadmium-106 < Indium-110
Explanation:
Atomic number - Number of protons.
The number displayed at the end of the element in this question represents the mass number (Number of protons + Number of neutrons).
The atomic number of the isotopes are given below;
Silver-109 --> 47
Cadmium-106 --> 48
Rhodium-122 --> 45
Indium-110 --> 49
Palladium-109 --> 46
Arranging in order of increasing atomic number from lowest to highest;
Rhodium-122 < Palladium-109 < Silver-109 < Cadmium-106 < Indium-110
The force of gravity on the 1 kg box is 2 N.
The formula for the force of gravity <em>F</em> on an object with mass <em>m</em> is
<em>F</em> = (<em>GmM</em>)/<em>d</em>²
Since <em>G</em>, <em>M</em> , and <em>d</em> are the same for both objects, (<em>GM</em>)/<em>d</em>² = a constant = <em>k
</em>). Then, we can write
<em>F = km
</em>
<em>F</em>₂/<em>F</em>₁ = <em>m</em>₂/<em>m</em>₁
<em>F</em>₂ = <em>F</em>₁ × <em>m</em>₂/<em>m</em>₁
If the 2.5 kg box is object 1,
<em>F</em>₂= 6.1 N × (1 kg/2.5 kg) = 2 N
<em>Note</em>: The answer can have <em>only one significant figure</em> because that is all you gave for the mass of the 1 kg object.
The reason people describe water as a universal solvent is because it dissolves almost anything.
Mass is never created or destroyed
