6 0

Explanation:

Many scientists believe that RNA, or something similar to RNA, was the first molecule on Earth to self-replicate and begin the process of evolution that led to more advanced forms of life, including human beings.

The main causes of climate change are: Humanity's increased use of fossil fuels – such as coal, oil and gas to generate electricity, run cars and other forms of transport, and power manufacturing and industry. Deforestation

Volcanologists can predict eruptions—if they have a thorough understanding of a volcano's eruptive history, if they can install the proper instrumentation on a volcano well in advance of an eruption, and if they can continuously monitor and adequately interpret data coming from that equipment.

What would most likely happen to a native predator species if a nonnative predator species were introduced to an area?
Fantom [35]

Answer:

B. The native species population would decrease because the nonnative species would be competing for food sources.

Explanation:

This question is describing the effect of invasive species. Invasive species are foreign species i.e. not native to a habitat or area, introduced into the area with the ability to outcompete and negatively affect the native species of that area.

Invasive species compete with the native species for food, space, mate etc., and tend to outgrow them. Hence, if a nonnative predator (invasive) species were introduced to an area, the native predator species in that area would decrease because the nonnative species would be competing for food sources.
