Answer:
(3) 4 cm' and 2.0 g/cm3
Explanation:
Given:
volume= V= 8 cm³
mass= m= 16 g
The density is the mass per volume of a substance, so the density of the rock is:
density= d= 16 g/8 cm³= 2 g/cm³
When we cut the rock in half, we have a half volume and a half mass:
V= 8 cm³/2= 4 cm³
m= 16 g/2= 8 g
But the density is not altered because it is an intrisic property - it does not change with the amount of subtance. Thus, the density of a half rock is:
d = m/V= 8 g/4 cm³= 2 g/cm³
Answer:
I answered 5 and 6
Explanation:
Prophase is where the nuclear envelope breaks down and chromosomes condense and become visible. Metaphase is where the chromosomes align in the middle of the cell, which in prophase, the newly visible chromosomes are scattered amongst the cells.
Interphase is the resting state of the cell, where a cell spends most of it's life in. But while it's active, cellular organelles double in number, the DNA replicates, and protein synthesis occurs.
That is a very interesting question.
No, it wound't be considered reproduction for many reasons and these are some of them:
Reproduction only occurs among living organisms.
Reproduction is more complex than something like erosion, where really, nothing complex happens appart from sedimentatino and things like that.
There are still many more reasons, but I won't write all of them.

<span>If you were given the AMINO ACID sequence, you could come up with a working DNA sequence, but even though this sequence may still make the same protein, it may not be the same DNA sequence that the original protein was coded from. This is due to the fact that there 64 different combinations for the four bases in DNA (A, T, C, & G), but only 20 amino acids to code for, therefore there's going to be overlap and there will be different codons that code for each amino acid </span>
