Answer:

1. by diseases

Explanation:

2 -An invasive species is a species that is not native to a specific location (an introduced species), and that has a tendency to spread to a degree believed to cause damage to the environment, human economy or human health.[2]

The term as most often used applies to introduced species that adversely affect the habitats and bioregions they invade economically, environmentally, or ecologically. Such species may be either plants or animals and may disrupt by dominating a region, wilderness areas, particular habitats, or wildland–urban interface land from loss of natural controls (such as predators or herbivores). This includes plant species labeled as exotic pest plants and invasive exotics growing in native plant communities.[3][4][5][6] The European Union defines "Invasive Alien Species" as those that are, firstly, outside their natural distribution area, and secondly, threaten biological diversity.[7][8] The term is also used by land managers, botanists, researchers, horticulturalists, conservationists, and the public for noxious weeds.[9]

What is hydrometer? Describe its use and any one type of hydrometer.​
nexus9112 [7]

Answer:

An instrument for measuring the density of liquids.

Explanation:

A hydrometer is an instrument used to determine specific gravity. It operates based on the Archimedes principle that a solid body displaces its own weight within a liquid in which it floats. Hydrometers can be divided into two general classes: liquids heavier than water and liquids lighter than water.

Thermohydrometers is one type of hydrometer.

using a lever to move a rock reduces the force a person must exert. what does it do to the work the person must do?
morpeh [17]

Using a lever to move a rock reduces the force a person must exert . It also reduces the work (effort ) the person must do.

Using a lever decreases the input force required to lift up the load, for example if a force of 900N is required to lift the load without a lever . Using the lever the input force decreases to 500N and as we all know by the formulae of work done :

Work done ∝  force applied

By this equation we can conclude that if the force to be applied on the load reduces by the use of a lever therefore the work to be done on the load will also reduce .

You can get a additional information about the lever system below :
