Answer:
the chlorophyll in the leaves
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.

Answer:
reduction in biodiversity by eliminating spawning and nursery grounds of aquatic life
Explanation:
Estuaries are transition zones localized between rivers and marine ecotones. These regions are influenced by marine factors such as waves, tides, and saline water, while rivers provide freshwater and sedimentary material. The mixture between seawater and freshwater is generally highly nutritive, thereby estuaries often represent high-production systems where fishes and shellfishes spawn and grow. However, many estuaries have suffered the negative effects of human activities, including deforestation, drainage, overfishing, nutrient pollution, etc.
Rhinoviruses and herpes simplex are just two common viruses out of the other thousands of them that the immune system has to protect the body against.
