Answer:
a domain of single-celled microorganisms
Explanation:
Rafflesia arnoldii, the corpse flower or giant padma, is a species of flowering plant in the parasitic genus Rafflesia. It is noted for producing the largest individual flower on Earth. It has a strong and unpleasant odor of decaying flesh. It is native to the rainforests of Sumatra and Borneo.
The answer to the question is D
Answer:
a. map unit
Explanation:
The map unit is the unit to represent the chances or the frequency of the recombination between the two genes. It shows the distance between the two genes present on the same chromosome. The frequency of recombination between two genes present on the same chromosome represents the distance between them that is measured in the form of map units. For example, two genes are said to be 10 map units apart if they exhibit 10% recombination. These genes are mapped 10 centimorgans apart from each other on the chromosome.
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.
