Select the correct answer from the list. In frost wedging, a crack expands when water ________ . When the water ______ it can seep into new fissures in the rock.
Answer:
freezes. melts/thaws
Explanation:
In frost wedging, a crack expands when water freezes. When the water melts/thaws it can seep into new fissures in the rock.
What is frost wedging?Water that seeps into cracks and freezes expands, resulting in frost wedging also known as ice wedging. The growth causes the fissures to widen. How often something freezes and thaws affects how effective frost wedging is.
During the "frost wedging" process, water seeps into rock fractures, causing the gaps to widen when the water expands upon freezing. The effectiveness of frost wedging is influenced by how frequently it freezes and thaws.
Frost wedging is a type of physical weathering in which rocks are degraded by the cycle of freezing and thawing.
Thus, Banks are filled above.

Explain hydrogen bonding in a water molecule
Answer:
Hydrogen bonding forms in liquid water as the hydrogen atoms of one water molecule are attracted towards the oxygen atom of a neighboring water molecule. ... The hydrogen atoms are not only covalently attached to their oxygen atoms but also attracted towards other nearby oxygen atoms.
Fungi compose a very minor component of life in marine ecosystems yet are vital to the health of terrestrial ones. This is primarily due to their ability to:
Answer:
Break down lignin.
Explanation:
The continual slow degradation of the phenolic portions of lignin (humic acids) provides a long-term supply of nutrients to plants. Phytoplankton (the primary producers in aquatic systems) do not synthesize appreciable amounts of lignin, and so fungi are not necessary to decompose it!
I think its B? Can someone explain it to me tho
Explanation:
I think it should be C because increase in temperature increases molecular motion. Therefore the speed of the moving molecules of both enzymes as well as the substrate will be accelerated. This
will enhance the colliding probability for both enzyme active sites and substrate molecules and more collisions occur between the enzyme active sites and substrate molecules generate greater chances for the reaction to occur. This can continue up to a certain point, after which there is a rapid decline in enzyme activity. This point is referred to
as optimum temperature. When the temperature increases beyond the optimum temperature, the hydrogen bonds, ionic bonds and other weak chemical bonds of enzyme active sites may be disrupted.
This will result a change in the shape of the active site of enzyme which will alter the complementary nature of the active site of enzyme molecules. Therefore, the
complementary binding of enzyme active sites and substrate molecules will be prevented. The above event is called as denaturation of enzyme molecules.
Therefore the rate of enzyme catalyzed reaction or in this case, photosynthesis will start to decline when the temperature increases beyond the optimum temperature and stops completely at certain
temperature, although rate of collision will keep on increasing.

True or false: Theoretically, it is possible (but very difficult) for a population to not evolve for a while.
It is true that it is possible for a population to not evolve for a while.
There is something called the Hardy-Weinberg theorem, which characterizes the distributions of genotype frequencies in populations that are not evolving.
There are 5 Hardy-Weinberg assumptions:
no mutation random mating no gene flow infinite population size and no selection (natural nor forced).You can see that some of these are kinda extreme and really hard to get, but with approximations, we can work.
For example, instead of an "infinite population size" we have enough with a really large population, such that genetic drift is negligible.
Concluding, yes, it is possible (but really difficult) for a population to not evolve for a while (at least, in nature), as long as the 5 assumptions above are met.

If the area had experienced a wet season two years after the drought instead of a dry season,
what kind of evolution would you expect? Explain your answer.
The organisms will start adaptation to that environment in order to survive.
If the area had experienced a wet season for two years after the drought instead of a dry season then we expect that the organisms that lives in that environment will start adaptation to that humid environment in order to survive.
What is adaptation?Adaptation occurs when an organism adapts certain actions to a certain environment in order to live more comfortable. If the organism do not adopt certain features then it will be extinct from that environment while on the other hand, those organism which adopt certain features will be able to survive so we can conclude that the organisms will start adaptation to that environment in order to survive.

Which of the following steps is required to break down pharmaceuticals, pesticides, and heavy metals in wastewater?
Aeration open basins
Chlorination and ozonation
Biological nutrient removal
Grit and bar screening
In order to remove the listed substances from wastewater, processes such as Chlorination and ozonation are most often used.
Chlorination is a process used in the purification of wastewater in order to achieve clean water that may be used for consumption or other uses. The process of chlorination exposes the wastewater to chlorine in an attempt to eliminate bacteria, viruses, and other potentially harmful substances and organisms from the water.
Much like chlorination, ozonation is a similar process used to purify wastewater. In contrast to the previous method, however, ozonation exposes the water to ozone. Though ozonation is safer and much more effective, these processes are often used together to eliminate harder to tackle elements such as
pharmaceuticalspesticidesheavy metalsand more from wastewater, which may not be removed by just one process alone.

From the question we are told
since ph can affect the activity of the antibiotics why would the Kirby bauer test require that the agar have a ph of 7.4
Generally
Agar has a ph value that should exist between 7.2 and 7.4 within a room temperature,given it solidifies and this should be when initially prepared
