c cell wall human cells do not have cell walls but do have cell membranes unlike plants that have both
Answer: B. They reproduce slower than unicellular organisms
Explanation:
In unicellular organisms there is a single cell which performs all the functions like digestion, respiration, and reproduction. The cell reproduce by cell division. The single parent cell divides into two identical daughter cells. But multicellular organisms exhibit multiple cells and their reproduction is complex. They reproduce by sexual mode of reproduction in which separate sex cells are produced when they fuse form zygote which is the precursor of new organism. This process is slower than that of the cell division and production of progeny by the unicellular organisms. Thus reproduction is slower in multicellular organism this is the disadvantage in multicellular organisms.
Since Molarity is moles per Liter, you will first need to convert the mL into L, which makes it 0.4321L. Next divide: moles on top, Liters on the bottom.
3.456 moles / .4321L = 7.998 M
Hello!
I'm going to have to infer that you meant "grams" and not "gallons" :-)
Anyways, to find the density, you need to the divide mass over volume (d = m/V).
Since we are given the volume being 15.0 mL, and the weight being 40.5 grams, we can find the density of the aluminum block.
40.5 grams / 15.0 mL = 2.7 g/mL
Therefore, the density of the aluminum block is 2.7 grams per milliliter.
Answer:
Ca: 1
Cl: 2
Explanation:
Since there is no subscript but there is the element, its assumed that there is at least 1, otherwise it would'nt be there
