If an atom like aluminum becomes an ion by losing 3 electrons, what is thecharge on the ion?
1+
2+
3+
3-

Answers

Answer 1
Answer: The basis to this Qs. is that electrons are negatively charged, and protons are positively charged. Essentially, the reason for an atom’s neutrality is a balance between the proton(s)/ positive charge(s) and the electron(s)/negative charge(s). So when 3 electrons are lost, we have an extra 3 protons left. As the charge of the proton is positive, your answer is “3+”.

D is the correct answer. Haploid cells only have one set of chromosomes. Meiosis results in duplication of cells with only one set of chromosomes in each - first chromosomes are copied, then DNA gets swapped, then the cells divide with one chromosome set in each of the four cells.

Sediments can be deposited by wind or water but water moves most. 
Loess is wind deposited particles. Alluvium is water deposited soil. 
The particles are one part but the place they settle impacts how they become rock because the geologic process will be different at the bottom of a deep marine sea than it is in a shallow off shore shelf. 

Only the very smallest particles will be moved to mid-ocean but there will be many plankton and other organic deposits. 

Coastal particles will vary in sizes . Water temperature will have more impact on the organic contributions here. Shallow tropical waters have coral and can form limestone.
