Compare surface, subsurface, and placer mining in terms of damage to the environment.
vfiekz [6]
Surface mining, which is also known as strip mining, is when soil and rock overlaying mineral deposit is removed. It can cause habitat destruction, air pollution from dust particles, soil erosion and pollution. Subsurface mining is removing deposits from the Earth by drilling underneath layers of rock and dirt. To keep the pathways clear, <span>mining companies have to pump out large amounts of water, which go into surface ecosystems. That disrupts the ecosystem by changing the pH conditions of soil and water sources. Placer mining is mining of stream bed deposits for minerals, a way of obtaining minerals and metal resources. Although, because it is small, causes less damage to the surrounding environment it still can disrupt river ecosystems with pollution and sediments. 
 

I hope this helps!!

REY [17]

The question is incomplete. The complete question is:

Question: If a horticulturist breeding gardenias succeeds in having a single plant with a particularly desirable set of traits, which of the following would be her most probable and efficient route to establishing a line of such plants?

A) Backtrack through her previous experiments to obtain another plant with the same traits.  

B) Breed this plant with another plant with much weaker traits

C) Clone the plant asexually to produce an identical one

D) Force the plant to self-pollinate to obtain an identical one.

Answer:

C) Clone the plant asexually to produce an identical one

Explanation:

Asexual reproduction is a mode of production of progeny from a single parent. It does not include the fusion of male and female gametes. Therefore, the progeny obtained from the asexual reproduction is genetically identical to the parent plant and is called a clone. One of the methods of asexual reproduction in plants includes vegetative propagation.

To maintain desirable traits in progeny, one must perform asexual reproduction in the single parent plant with such traits. The asexual reproduction would produce the progeny having all the desirable genetic traits as that of the parent plant.

<h3>Neurotransmitters : </h3>

it is known as body's chemical messenger. it transmit signals from neuron to muscle and neuron to neuron.

these are only created in the neuron cells.

neurotransmitters level can only increase when we take vitamines like vitamin B6 and minerals like Iron, niacin, folate.

The level also increases when we eat more protein, get enough sleep,meditate and exercise regularly.

<h3>Epinephrine:</h3>

it is a type of neurotransmitters.

it is used for emergency treatment of severe allergic reactions due to insect bites or medicines, foods, etc.
