What are the characteristics of supernovae?

Answers

Answer 1
As the star runs out of nuclear fuel, some of its mass flows into its core. Eventually, the core is so heavy that it cannot withstand its own gravitational force. The core collapses, which results in the giant explosion of a supernova. The sun is a single star, but it does not have enough mass to become a supernova.

Describe the scientific theory of cells (cell theory) and relate the history of its discovery to the process of science.

Answers

Answer:

The cell theory states that all living organisms are made up of cells and each cell is the fundamental and functional unit of the living organism. The last point of the theory is that each cell is produced by a pre-existing cell.

The cell discovery was made by Robert Hooke with the help of the compact microscope was made by him. He observed the cell wall of the cell in cork and after him, many other scientists proved the presence of cells and presented evidence of the cell theory.

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

why does the addition of phosphate compounds to aquatic areas have a dramatic effect on biological productivity

Answers

Answer:

Explanation:

The presence of the phosphates compound here act as limiting factors for plant growth in aquatic ecosystems, because they do not dissolve easily in water . Then eutrophication( this is the gradual rise in the concentration of phosphorus, nitrogen, and other plant nutrients in an aging aquatic ecosystem.) starts acting wherever there is too much phosphate, it promotes excessive amount of algae and it will exhaust the oxygen.

How are bacteria different from viruses?

B. Bacteria are eukaryotes.
C. Bacteria are not killed by antibiotics.
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.

b. It seems to react to being touched
c. It possesses a purposeful anatomical structure that differs from one another
d. It's body is bilaterally symmetrical

Answers

Answer: It's body is bilaterally symmetrical
