Answer:
48g
Explanation:
Volume of rock=16cm^3 (1 ml=1 cm^3)
Density=3 g/cm^3
Mass=?
d=m/v
3g/cm^3=m/16cm^3
3g/cm^3*16cm^3 =m
Therefore, m= 48g
True because some fossils only lived in certain places
Answer:
<h2>The chloroplast is involved in both stages of photosynthesis. The light reactions take place in the thylakoid. There, water (H2O) is oxidized, and oxygen (O2) is released. ... In these reactions, the energy from ATP and NADPH is used to fix carbon dioxide (CO2).</h2>

<span>Tertiary</span> structure - three-dimentional structure of one polypetide chain.
Proteins are considered as for their conformation in four different stages:
Primary structure is referred solely to the sequence of amino acids<span> in the polypeptide chain.
</span>Secondary structure is the immediate basic folding of a protein and it can be α-helix and β-sheets.
Tertiary structure is the three-dimentional folding of a singles polypetide.
Quaternary structure is the thee-dimenional structure that results from the combination of two or more individual polypetides working as single protein.
