The answer is <span>Special RNA polymerase, peptidoglycan in cell walls, ester-linked fatty acids. 

Bacterial cell wall consists of peptidoglycans, not of cellulose or chitin. They also have ester-linked fatty acids, like eukaryotes. Ether-linked fatty acids are characteristics of Archaea. Also, bacteria have special RNA polymerase, unlike Eukaryotes that have three different type of RNA polymerase.</span>

Answer:

The correct answer is "Special RNA polymerase, peptidoglycan in cell walls, ester-linked fatty acids".

Explanation:

There are some key markers that identify a Bacteria among other species that belong to the other two domains (Archaea and Eukarya). These key markers include: A special RNA polymerase, bacteria has a one and only special type of RNA polymerase with a single regulatory subunit and four catalytic subunits; peptidoglycan in cell walls, most bacteria have a cell wall made of peptidoglycans, which is the target for many antibiotics; ester-linked fatty acids, ester-linked fatty acids are an unique biomarker for Bacteria, while other organisms such as Archaea have ether-linked fatty acids.

Which of the following statements correctly distinguishes between an acidic and a basic solution?
zepelin [54]
The correct option is A. 
A basic solution has a high concentration of hydroxide ions more than any type of ion and that is why it is basic in nature. An acidic solution has a higher concentration of hydrogen ions and that is why it is acidic in nature. A neutral solution has equal amount of hydroxide and hydrogen ions. Solutions are usually classified as either basic or acidic based on their hydrogen ion concentration.

REY [17]

Answer:

D) The fungicide will reduce the stability of the ecosystem because nutrients in the soil will be less likely to be recycled, directly impacting plant nutrition and growth.

Explanation:

Fungicide are primarily applied to an area to kill off fungi species in that place.

Fungi are very important groups of organisms. They are natural "recyclers".

In a food chain or web they can be classified as decomposers.

Decomposers are organisms that takes feeds on dead and decaying organic matter.

The produce useful materials and releases nutrients from life back into nature.

Killing them off by applying fungicides is a damaging act to their sustenance.

Without decomposers such as fungi, the ecosystem becomes less stable  and soil nutrients will not be properly recycled.

romanna [79]

Answer;

C. Be more susceptible to disease and famine

Explanation;

-A species that has experienced a severe bottleneck event would be expected to be more susceptible to disease and famine.

-The Bottleneck Effect occurs when there is a disaster of some sort that reduces a population to a small handful, which rarely represents the actual genetic makeup of the initial population.

-It may be caused by various events, such as an environmental disaster, the hunting of a species to the point of extinction, or habitat destruction that results in the deaths of organisms.
