Molecules that are present in the membranes of gram-negative bacteria and are the best known pamps are called ________.
miskamm [114]

Molecules that are present in the membranes of gram-negative bacteria and are the best-known pamps are called Bacterial lipopolysaccharides (LPSs).

Bacterial lipopolysaccharides (LPS) are the primary outer surface membrane elements present in almost all Gram-negative bacteria and it act as extremely strong stimulators of the innate or natural immunity in the diverse eukaryotic species ranging from insects to humans.

Eukaryotes are the organisms whose cells contain a nucleus and other membrane-bound organelles. eukaryote, any cell or organism that possesses a clearly defined nucleus. The first eukaryotic cells was evolved about 2 billion years ago. In this Cells with nuclei surrounded by a nuclear envelope with nuclear pores.

Which of these statements describes a limitation of the Antarctic Treaty
ZanzabumX [31]

Answer:

<em>The correct option is D) It does nothing to protect the atmosphere over Antarctica.</em>

Explanation:

On December 1, 1959, the Antarctic Treaty was signed in Washington. According to this treaty, Antarctica was to be used for peaceful purposes. This treaty regulates international relations with the Antarctica region. Freedom to different scientists for research in this area was given through this treaty.

However, the treaty did not discuss anything related to the protection of the atmosphere around Antarctica. Hence, option D can be considered to be a limitation of the Antarctic Treaty  System.

Choose one region on the world map. How does the climate their differ during El Niño and La Niña?
ratelena [41]

Answer:What are El Niño and La Niña?

El Niño and La Niña are opposite phases of a natural climate pattern across the tropical Pacific Ocean that swings back and forth every 3-7 years on average. Together, they are called ENSO (pronounced “en-so”), which is short for El Niño-Southern Oscillation.

The ENSO pattern in the tropical Pacific can be in one of three states: El Niño, Neutral, or La Niña. El Niño (the warm phase) and La Niña (the cool phase) lead to significant differences from the average ocean temperatures, winds, surface pressure, and rainfall across parts of the tropical Pacific. Neutral indicates that conditions are near their long-term average.

What happens during El Niño and La Niña?

During El Niño, the surface winds across the entire tropical Pacific are weaker than usual. Ocean temperatures in the central and eastern tropical Pacific Ocean are warmer than average, and rainfall is below average over Indonesia and above average over the central or eastern Pacific.

Rising air motion (which is linked to storms and rainfall) increases over the central or eastern Pacific, and surface pressure there tends to be lower than average.  Meanwhile, an increase in sinking air motion over Indonesia leads to higher surface pressure and dryness.

Anomalous ocean warming in the central and eastern Pacific (orange) help to shift a rising branch of the Walker Circulation to east of 180°, while sinking branches shift to over the Maritime continent and northern South America. NOAA Climate.gov drawing by Fiona Martin.

During La Niña, it’s the opposite. The surface winds across the entire tropical Pacific are stronger than usual, and most of the tropical Pacific Ocean is cooler than average. Rainfall increases over Indonesia (where waters remain warm) and decreases over the central tropical Pacific (which is cool). Over Indonesia, there is more rising air motion and lower surface pressure. There is more sinking air motion over the cooler waters of the central and eastern Pacific.

Generalized Walker Circulation (December-February) anomaly during La Niña events, overlaid on map of average sea surface temperature anomalies. Anomalous ocean cooling (blue-green) in the central and eastern Pacific Ocean and warming over the western Pacific Ocean enhance the rising branch of the Walker circulation over the Maritime Continent and the sinking branch over the eastern Pacific Ocean. Enhanced rising motion is also observed over northern South America, while anomalous sinking motion is found over eastern Africa. NOAA Climate.gov drawing by Fiona Martin.

Between the warm phase (El Niño) and cool phase (La Niña), scientists describe conditions as “ENSO-neutral.” Neutral means that the temperatures, winds, convection (rising air), and rainfall across the tropical Pacific are near their long-term averages.
