<span>Myoglobin, like most proteins, has a complex three dimensional structure that is formed from many twisted helices. There are more than one helix, and it does not look like beads on a straight piece of string. It is not branched.</span>
Velocity is defined as displacement over time. Could you have possible meant viscosity? If so, viscosity is defined as the state of being thick, sticky, and semifluid in consistency, due to internal friction. And example of a substance with a high viscosity would be honey.
Answer:
Giraffe, rhinoceros, grasshopper, mouse, and deer
Explanation:
Primary consumers eat producers (plants). Therefore, all the animals that eat the plants are primary consumers.
Answer:
The amount of water on the Earth is constant, or nearly so. Actually, the amount is increasing ever so slightly due to volcanic eruptions expelling water vapor into the atmosphere, but, for all practical purposes, the amount of water (as a gas, liquid and as snow and ice) can be considered to be constant.

Answer:
1.59x10⁻¹⁰m
Explanation:
To solve this question we must know that the length of the cubic cell, X, is equal to:
X = √8 * R
<em>Where R is the atomic radius of germanium</em>
And that in 1 unit cell there are 4 atoms of germanium.
To solve this question we must find the mass in 1 unit cell, with this mass we can find the volume of the cube and the length. With the length we can know the atomic radius:
<em>Mass in 1 unit cell -Molar mass Ge = 72.64g/mol:</em>
4 atoms Ge * (1mol / 6.022x10²³ atoms) = 6.64x10⁻²⁴ moles Ge
6.64x10⁻²⁴ moles Ge * (72.64g / mol) = 4.825x10⁻²²g Ge
<em>Volume unit cell:</em>
4.825x10⁻²²g Ge * (1cm³ / 5.32g) = 9.07x10⁻²³cm³
<em>Length unit cell:</em>
∛9.07x10⁻²³cm³ = 4.49x10⁻⁸cm * (1m / 100cm) = 4.49x10⁻¹⁰m
<em>Atomic radius Ge:</em>
4.49x10⁻¹⁰m / √8 =
<h3>1.59x10⁻¹⁰m</h3>
