The brown tree snake is native in areas such as Australia and eastern Indonesia. In
those ecosystems, the brown tree snake is not causing the decline of bird or tree
populations. So what makes this same species damaging in Guam? Identify some
characteristics a species may possess that would fuel its ability to cause ecological

for six years an artificial fertilizer is used on a apple orchard the orchard is next to a stream which empties in to a slat water bay during the last 5 years researchers have observed an increase in algae in the bay they have also sampled fish populations in the bay each year apex...

A spring is a natural discharge point of subterranean water at the surface of the ground or directly into the bed of a stream, lake, or sea. Water that emerges at the surface without a perceptible current is called a seep. Wells are holes excavated to bring water and other underground fluids to the surface.

The image shows a cross-section of land scape.

B)Phosphorus has a larger atomic mass.

As we move right in the periodic table, both atomic number and atomic mass increases. Magnesium comes under S-block elements (Group 2) and Phosphorus comes under P-block elements (Group-15).

Rank the following cities in order of earthquake risk from high risk to low risk:

A scientist look for in a plant that would identify it as a club moss rather than a liverwort.

Astronomers are able to detect the dimmer star because its gravity causes the bright star to . Astronomers can also spot the dimmer star by observing a phenomenon called a(n) binary.

when soaked in dilute sodium chloride solution onion gain mass because of the process of osmosis.

 Explanation: Osmosis is a process when there is movement of water from the region of comparatively higher concentration to the region of lower concentration across in a permeable membrane.

Example with explaination :

99% percentage of errors does our body's "auto-correct",system detect.

Errors associated with protein mismatch and translation is automatically detected by the body system. Once, mismatch occurs, synthesis stops, hence, this error is almost always detected at all times. Therefore, the percentage of errors automatically detected is about 99%.
