It has a positive impact on the environment by releasing chemicals into the environment.
It has a negative impact on the environment by allowing toxic chemicals to harm wildlife.
It has a negative impact on the environment by creating new niches for wildlife to inhabit

It has a negative impact on the environment by allowing toxic chemicals to harm wildlife.

Explanation:

Mining refers to the act of extracting minerals and other valuable solids from the earth's crust. The process of mining can have adverse effect on an ecosystem in the sense that wildlife is threatened during the process.

During the mining process, chemicals, which are toxic to living organisms, from the minerals gets washed into the areas surrounding the mining site. Thereby, causing serious harm to the wildlife living in those areas.

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus
