Answer:
Option D = 3.4 g/mL
Explanation:
Given data:
Volume of water = 21.2 mL
Volume of water + object = 27.8 mL
Mass of object = 22.4 g
Density of object = ?
Solution:
First of all we will calculate the volume of object.
Volume of object = Volume of water+ object - volume of water
Volume of object = 27.8 mL - 21.2 mL
Volume of object = 6.6 mL
Density of object:
d = m/v
d = 22.4 g/ 6.6 mL
d = 3.4 g/mL
Answer:
all you will need to understand the basic energy change results the 2nd law predicts. ... We can transform some of it (but not all) into useful work.
Explanation:
The answer would be secondary succession.
Primary succession happens before an ecosystem is established. In contrast to it, secondary succession happens after a disaster that destroys most of the species in the land.
In this case, the ecosystem is already established. The forest fire is the disasters that destroy the ecosystem, allowing the secondary succession.
The answer is plasmid. The plasmid is a ring double strand DNA which can replicating themselves separately. It is often used as genetic engineering materials for expressing or study function of a specific gene. Flagellum is a structure of prokaryotes which used for movement.
