Answer:
The two types of skeletal muscle fibers are slow-twitch (type I) and fast-twitch (type II). Slow-twitch muscle fibers support long distance endurance activities like marathon running, while fast-twitch muscle fibers support quick, powerful movements such as sprinting or weightlifting.

They both help shape how the animal looks like today, & with the traits that the development gives to the animals, it helps them do the tasks they need to do to survive easily. Without these development, the species would become extinct sooner or later

Considering the definition of density, you obtain that:
- Part A: the density of gold is 19.3 g/cm³.
- Part B: the density of iron is 7.8 g/cm³.
<h3>Definition of density</h3>
Density is defined as the property that allows to measure the amount of mass in a certain volume of a substance.
The expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:
density= mass÷ volume
It can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.
<h3>Density in this case</h3>
In this case, you know that:
- A sample of gold has mass of 38.6 grams and a volume of 2 cm³.
- A sample of iron has a mass of 46.8 grams and a volume of 6 cm³.
Replacing in the definition of density:
- Gold: density= 38.6 g÷ 2 cm³
- Iron: density= 46.8 g÷ 6 cm³
Solving:
- <u><em>Gold: density= 19.3 g/cm³</em></u>
- <u><em>Iron: density= 7.8 g/cm³</em></u>
In summary, the density of gold is 19.3 g/cm³ and the density of iron is 7.8 g/cm³.

Normal hemoglobin levels:
Older men: 12.4 to 14.9 gm/dL
Older women:11.7 to 13.8 gm/dL
Possible causes for anemia is blood loss from an injury/surgery, not enough production of red blood cells, or it's happening too much destruction of red blood cells. (Whatever the cause is, the patient is losing blood)
To determine why, the doctor should request a blood test with the following information:
Complete blood count (CBC)
Iron levels and ferritin levels,
Vitamin B12 and folate,
Reticulocyte count,
<span>Bilirubin and maybe some s</span>pecial blood tests to detect if the cause it's from a immune attack.
It's also possible to need a sample of bone marrow but it's rare.
