Answer: Formation of peptide bonds
Explanation:
The structure of peptidoglycan layer found in the cell wall of bacteria consists of linear polymer chains of two alternating amino sugars that are crossed linked by peptide bond. .
The sheet is formed from the cross linkages of the alternating amino-glycan chains by peptide linkages. Hence the word peptidoglycan.
The two amino sugars are N-acetylglucosamine and N-acetylmuramic acid and are linked covalently by β-1,4-glycosidic bond.
Answer is a each strands are joined by peptide bonds.
Answer:
It is a Barometer
Explanation:
A Thermometer meaures temperature.
A Wind Vane measures the direction of the wind.
A Anemometer measures speed and direction.
Barometer measures air pressure.
<u>Answer</u>: d. All of the above are true.
If an organism lives currently in a specific environment, it does not mean that it cannot spread further on due to changes. A good example are invasive species that under human influence have spread in many areas of the globe where they have had a negative impact on native ecosystems.
Our planet is a complex system with many interconnected parts. Thus, what happens in one region can affect many other regions as both air and water move globally. The same is true for locally released carbon dioxide that will result in a local increase in air temperature. However, this can change the global air currents or 
itself can move and accumulate in other regions.
Because Putting a carrot in salty water will make it shrivel up, as water leaves the carrot's cells to enter the salty water -- a process called osmosis.
