Answer: 14 more points
Explanation: Good luck! :D
Brayden and Gavin scored 49 points in all
Cole and Freddy scored 63 points in all.
63 - 49 = 14

Answer:
. A DNA molecule in a human chromosome can be up to 250 million nucleotide-pairs long; in contrast, most RNAs are no more than a few thousand nucleotides long, and many are considerably shorter.
Answer:
5. All magnesium atoms have the same number of neutrons
Explanation:
Magnesium (Mg) is a chemical element. Its atomic number (Z) is 12 (number of protons in the nucleus of the Mg atom).
The Magnesium has three stable isotopes: 24Mg, 25Mg and 26Mg. All these isoforms have 12 protons in their atoms (same atomic number), however they vary in the mass number of the atom (M).
The mass number of the atom (M) is equal to the sum of protons and neutrons in the nucleus.
Based on this information we can know how many neutrons each isotope has
24 Mg = 12 protones + 12 neutrons
25Mg = 12 protones + 13 neutrons
26Mg = 12 protones + 14 neutrons
In this way we conclude that <u>not all magnesium atoms have the same number of neutrons</u>
Answer:
Natural organic matter is ubiquitous in soils, waters and sediments. In agriculture, natural organic matter is important because of its positive effects on the structure, water retention and nutrient properties of soils.
Natural organic matter also interacts with metal ions and minerals to form complexes of widely differing chemical and biological nature. Solubility, mobility and toxicity of many trace metals are strongly correlated with the concentration of natural organic matter in soil and water.
Natural organic matter creates problems for the water supply industry, however, requiring removal to minimize water color and giving rise to potentially harmful chemical byproducts as a result of chlorination. Through a process called "bio-fouling," natural organic matter is also a major culprit in degrading the performance of membrane filtration systems used for water purification and desalination.
Explanation:
Does this answer your question or do you need me to answer it differently because I kind of confused myself lol.
