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.

It's important to not misuse or overuse antibiotics because of the risk of drug addiction, and the side effects (overdose, and decline in physical health) of having misused and/or overused an antibiotic. In fact misusing or overusing antibiotics could create more problems than what you originally used the antibiotics for.
Answer:
The genetic engineering produced on these tomatoes was the solution to reduce the amount of chemical usage to crops as well as introducing a greater disease resistance, insect resistance, and increase shelf life. Conclusively, scientists and farmers still wanted to keep their natural color and flavor, yet change it into a more positive way.
70 years ago, spoke of the dangers of nightshade foods, covering all this ground, and stating that traditionally in South America, where potatoes and tomatoes come from they were eaten as medicine – that is given specifically for a short period time for a specific condition.
Hope this helped you!
Explanation:
Answer:
Angiosperms are vascular plants bearing the seeds in fruits or mature ovaries whilst gymnosperms are other types of the plant which bears the seeds directly on the sporophylls but without any cover.
Explanation:
Examples of gymnosperms include cypress,pine, redwood, spruce and ginkgo.
Examples of angiosperms include apple, banana,peach, cherry and orange.
Also, angiosperms are seeds producing flowering plants whose seeds are enclosed within an ovary.
Gymnosperms are also seeds producing non flowering plants whose seeds are unenclosed.
