I don't know what the lotka thing is, but I'd guess c and d because their coefficients are closer
B) Nucleus!
Prokaryotic cells do not have a nucleus, and the Nucleus in a Eukaryotic cell are large and very hard to miss (if that matters to you!)
Answer:
Carbon:0
Calcium:1
Chloride:2
Hydrogen:0
Oxygen:0
Explanation:
Ca is calcium and there is only one in the compound due to no subscripts. Cl is chloride with a subscript of 2, meaning there are 2 atoms of that element in this compound.
Answer:
<em>The correct option is d) mammals</em>
Explanation:
Studies made by scientists have shown that mammals are nor able to evolve fast enough as compared to other groups of animals. As a result, mammals tend to become more extinct as compared to organisms of the groups. Many mass extinctions of mammal organisms have been recorded over the past 400 years. The mammalian organisms possess little biodiversity in them as compared to organisms of the other phyla.
I'd go with A, Nucleus. I hope this helps!
