Surface mining destroys vegetation and affects soil strata. Mining disrupts to topsoil microorganisms. Reclamation operations that dilute topsoil with subsoils can degrade soil.
What is surface mining?Surface mining is a type of mining in which the soil and rock covering the mineral deposits are removed. It's the other way to mine underground. The rock on top is left in place, and the needed minerals are taken out through shafts or tunnels.
Surface mining can hurt fish and aquatic resources by causing erosion and sedimentation, drying up wetlands, rerouting and channelizing streams, and putting toxic chemicals into the surface water and aquifers.
This will further disrupt plant life on surface.

Explain how bacteria become resistance to
antibiotics, supporting Darwin's theory..
Answer:
They adapt over time to the antibiotics.
Explanation:
Because of Darwin's theory of natural selection, the bacteria that are resistant to antibiotics will multiply whereas the ones that don't survive will die off. Over time, the species will only consist of those bacteria that are resistant, because they are the ones that survived. Hope this helps!
Answer:
Since bacteria reproduce at a very fast rate, they can also develop mutations; creating new strains. Some bacteria might become resistant to certain antibiotics because of these mutations. The evolution of the bacteria supports Darwin's theory of evolution !

A tomato plant grew 6 inches the first week, before slowing to an average of 0.5 inch per day. How many days will it take before the tomato plant reaches a height of 16 inches? Use the equation 16 = 0.5d + 6
Answer:
C-Attaching to a host
Explanation:
It wouldn’t be entering the cell because I’ve learned that it needs to attach to a host first, and it wouldn’t be replicating because it needs to be in the host before it starts. Which leaves assembling and attaching. It is attaching and not assembling because assembling is one of the last ones, second to last step, so the answer would be attaching.
Which description identifies a factor that influences the flow of water through the plasma membrane of a human cell?
A. The size of the phospholipids and proteins composing the plasma membrane
B.the concentration of solutes on either side of the plasma membrane
C.the presence or absence of a cell wall outside the plasma membrane
D.the number of contractile vacuoles on the surface of the plasma membrane
Answer:
A
Explanation:
Osmosis refers to the movement of water molecules across a selectively permeable membrane. During this process, water molecules move from an area of high concentration to an area of lower concentration.
A factor that influences the flow of water through the plasma membrane of a human cell is the concentration of solutes on either side of the plasma membrane (Option B).Osmosis is a type of passive transport mechanism that does not require energy to occur.During osmosis, water diffuses through a selectively permeable membrane from an area of high water concentration to an area of lower water concentration.In an isotonic cell, the concentration of solutes and water molecules is equal on both sides of the plasma membrane.In conclusion, a factor that influences the flow of water through the plasma membrane of a human cell is the concentration of solutes on either side of the plasma membrane (Option B).

During cellular respiration what is the direct source of the energu used in the cells of consumers?
Answer:
Consumers use chemical energy from the chemical bonds within organic molecules such as carbohydrates, lipids, and amino acids.
Explanation:
Heterotrophs are consumers; they ingest or absorb organic matter (lipids, carbohydrates, proteins, etc.) made by autotrophs or producers for their energy consumption. Autotrophs include plants, bacteria, and other photosynthesizing organisms, while heterotrophs include animals, fungi, protists, and bacteria.
Heterotrophs obtain energy from food through the process of cellular respiration. For instance, during aerobic respiration in mitochondria, they break down sugars in the form of glucose into carbon dioxide and water to obtain energy in the form of ATP or adenosine triphosphate.
aerobic respiration: C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
glucose+ oxygen → carbon dioxide+ water+ energy

1. Which of the following is a characteristic associated with an organism's niche but not with its habitat?
a. climate
b. soil quality
c. place in the food web
d. location within the ecosystem
A characteristic that is associated with an organism's niche but not with its habitat is the place in the food web. Thus, the correct option for this question is C.
What is Habitat?Habitat may be defined as a type of natural environment for which a particular species is best adapted due to natural selection. In a more simple sense, habitat may also be characterized as an area where the basic demands of an organism are fulfilled like food, space, and mating partner.
According to the context of this question, a pace in the food web determines the position and the type of food that an organism naturally eat or consume. As it connects the organisms with the source of energy.
But in reality, it does not describe any characteristics of the habitat to which a particular organism belongs. This is because the food web is the pictorial representation of organisms on the basis of their food habit and nature.
Therefore, a characteristic that is associated with an organism's niche but not with its habitat is the place in the food web. Thus, the correct option for this question is C.

area of low concentration with the use of a protein it is an example of what type of
passive transport.
Osmosis
Facilitated diffusion
Active Transport
Diffusion
Answer:
Osmosis
Explanation:
Osmosis is the spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides.
This direction is from high concentration to low concentration, this will create equilibrium.

Which of the following is NOT evidence for Endosymbiotic Theory?
Answer:
mitochondria and chloroplasts can not survive outside of the cell
Explanation:
The statement that mitochondria and chloroplasts cannot survive outside of the cell is not a supporter of the endosymbiotic theory. So the correct option is A.
What is the endosymbiotic theory?
It's possible that eukaryotic cells originated when several cell types fused to form one. They started coexisting in what are known as symbiotic partnerships. The endosymbiotic theory describes how this may have occurred. One creature that resides inside of another is known as an endosymbiont. Your own cell and all other eukaryotic cells are animals formed of other species' components.
Both the chloroplast and the mitochondrion are organelles that were formerly free-living cells. They were prokaryotes that were ensconced within other cells (host cells). They may have become a part of the other cell by being eaten (a process known as phagocytosis), or they could have been parasites living inside the host cell.
The inner cell lived and flourished with the host cell rather than being ingested by or destroying it. It resembles a landlord and a renter in certain ways. The organelle pays rent by producing energy that the host cell may consume, and the host cell offers a cozy and secure home.
The organelle and the host cell have developed together throughout time as a result of this long-ago event. The two are now inextricably linked. Even while they now work as a single organism, if we look closely, we can still see traces of the organelles' former lives as free-living entities.
Therefore the correct option is A.
