6 0

Answer:

The correct answer to the following question will be "Tests or experiments".

Explanation:

  • Descriptive investigations attempt to build assumptions from either the predictions of the phenomena, even as experimentally investigated were mostly designed to allow the research scientist to make comparisons under various situations with both the control behavior.
  • There are indeed enough that-called comparison investigations, that also gather information analyze varying environments but don't even include the regulate location.

So that the above would be the appropriate answer.

How are viruses different from bacteria
Butoxors [25]

I believe the correct answer is that viruses are not cells while bacteria are cells with organelles.

<h2>Explanation:</h2><h3>Viruses</h3>

Viruses can simply be explained as genetic materials enclosed in capsules that protects them from the immune system.

Viruses need a host to survive since they lack a mechanism to replicate in meaning they are obligate intracellular organisms.

Reproduction of viruses is through attaching their DNA or RNA into the machinery of the host that replicates them as part of the normal DNA of the cell.

They are the smallest living organisms and cannot be seen microscopically.

They cannot be infected but rather can infect bacteria

They have a capsid that protects the viral material and also contains the receptors attachments that are able to attach to the specific sites which they are infecting. Some of them have an extra layer of a membrane that is called an envelope that further protects the viruses from their hostile environment

They are treated by antiviral medications that affects their replication on normal cells.

They are pathogenic by destroying the cells they enter after successfully replicating their genetic material.

They can either have DNA or RNA but never both.

<h3>Bacteria</h3>

They are cellular prokaryotes with cell organelles that keeps them functional

They can be obligate intracellular organisms or they can survive outside the cell without any problem depending on the particular species of the bacteria since they have cell organelles that can function.

Bacteria reproduce through a process called binary fission where the cell organelles just double up and the cell pinches into 2 different sections with equal distribution of genetic materials forming 2 different cells.

They can be infected by types of viruses called bacteriophages that use the hosts nucleoid to replicate.

They have a cell membrane and a cell wall which encloses the inner contents of the bacteria and also protects the bacteria from the immune system.

They are treated by antibiotics such as β-lactam antibiotics that destroys their cell wall making it porous and the cell eventually dies.

They do not enter the host for reproduction but rather they kill the host through toxins such as toxin A and toxin B

They do not have a nucleus but have the nucleoid that contains the DNA of the bacterium.

A function of a cell membranes in humans is the
Helga [31]
The very function, or job of CELL MEMBRANES is to protect the cell from it's surroundings, or in other words, to keep it safe. It controls the movement of substances in and out of cells and organelles, like a guard watching for suspicious activity and protecting something.

The cell membrane itself is a thin, flexible layer around the cells of all living things. It separates the inside of the cells from the outside of the cells.

Why do organisms require different levels of cellular organization
