You are solving a density problem, where density = mass/volume. Your volume of liquid is 2.1 milliliters. Your mass of the liquid is 2.811 grams. What is the density of the liquid using the correct number of sig figs?

Answers

Answer:

Density = 1.3386kg/m³

Explanation:

Given the following data;

Volume = 2.1 millimeters to meters = 2.1/1000 = 0.0021 meters

Mass = 2.811 grams to kilograms = 2.811/1000 = 0.002811 kilograms

To find the density;

Density can be defined as mass all over the volume of an object.

Simply stated, density is mass per unit volume of an object.

Mathematically, density is given by the equation;

[tex]Density = \frac{mass}{volume}[/tex]

Substituting into the equation, we have;

[tex] Density = \frac {0.002811}{0.0021} [/tex]

Density = 1.3386kg/m³

D. Bacteria can replicate themselves without help from a living cell.

Answers

Answer:

d

Explanation:

bacteria can replicate themselves without help from a living cell.

Bacteria are capable of self-replication without the assistance of a live cell. So, the correct option is D.

What is Bacteria?

Bacteria are ubiquitous, generally free-living creatures that are frequently made up of one biological cell. They make up a significant portion of the prokaryotic microbial kingdom. Usually a few micrometres in length, bacteria were among the earliest life forms to appear on Earth, and are ubiquitous in most of its environments.

Bacteria lack a nucleus bound to the membrane and other internal components and are consequently placed within the group of unicellular life-forms called prokaryotes. Prokaryotes have dominated life on Earth for at least three-quarters of its existence and have adapted to nearly all of the planet's biological niches. Bacteria are capable of self-replication without the assistance of a live cell.

Therefore, the correct option is D.
