Answer:
A sea sponge 760 million years old
Explanation:
It's unclear exactly how long sea sponges have been around, but they are at least old enough to be the longest-existing creatures on Earth, outside the realm of microorganisms (like bactery). The oldest evidence of a sea sponge found was a fossil discovered just last year in a 760-million-year-old rock. This beat the previous record for oldest sponge fossil, a 635-milloon-year-old sponge discovered in 2009. There may be still older fossils yet to find. But finding an older species is unlikely,as these simple organisms appear to be the progenitors of much more complicated life, including the first multicellular animals.
Answer: Carbon Dioxide, Nitrogen, Argon, and oxygen.
Explanation: Earth's atmosphere is 78% nitrogen, 21% oxygen, 0.9% argon, and 0.03% carbon dioxide with very small percentages of other elements.
The answer is all of them. I just took the test. Hope this helps! :)
The correct answer is D. Plants growth increases in the spring.
This is because observations must be objective, meaning that all people would state the same idea. This is not true for options like A and B, which are popular opinions, but definitely could be argued opinionatedly rather than with evidence that could support option D.
Hope this helps!
Not that great at maths so bear with me.
To find out how many containers she used: 30/10 = 3 So 3x3 is 9 then x by two to find out how much water : 9x2=18
