Answer:

Community resilience is the sustained ability of a community to use available resources to respond to, withstand, and recover from adverse situations. This allows for the adaptation and growth of a community after disaster strikes. Communities that are resilient are able to minimize any disaster, making the return to normal life as effortless as possible. By implementing a community resilience plan, a community can come together and overcome any disaster, while rebuilding physically and economically.

C3 transferase decreases Rho activity and contractility by decreasing the number of stress fibers and thus also reducing wrinkles

Explanation:

Rho protein is a small GTPase, i.e., an enzyme that binds GTP to hydrolyze it to GDP, which is known to mediate the formation of stress fibers and focal adhesion. Rho protein is involved in diverse cellular functions including, among others, adhesion, motility, and division by reorganization of the actin cytoskeleton. The bacterial toxin C3 transferase derived from Clostridium botulinum is able to lock Rho in an inactive state. C3 transferase adds an ADP-ribose to Rho, thereby leading to the accumulation of a Rho-guanine nucleotide dissociation inhibitor (GDI) complex in the cytoplasm. In consequence, C3 transferase functions to decrease contractility by blocking Rho activity, decreasing the number of stress fibers and leading to a reduction in wrinkles.

In a pond ecosystem, the frog serves as a consumer. The correct option is D.

Consumers are lifeforms that require food to produce energy. These organisms are known as heterotrophs, which means they must consume something else as food.

In a pond ecosystem, tadpole larvae of frogs, fishes, and other underwater animal life that eat green plants and algae are the primary consumers.

Thus, the correct option is D.

Answer:

a) Beaver-dam buildings → (iii) Pond floods

b) Forest fire → (i) New plants can grow because of an increase in sunlight on the forest floor

c) Lack of rainfall  →  (ii) Zebras migrate farther to find water holes

d) Invasive water plants arrive →  (iv) Sunlight is blocked for native seagrasses

e) Grasshopper outbreaks  →   (v) Crops are wiped out along the prairie

f) Coyote disease decreases the population →  (vi) Mice population explodes

Explanation:

a) Beaver-dam buildings → (iii) Pond floods

This is an example of how some species might produce damages in ecosystems. Beavers are known for their dams, where they hide from predators, find shelter, reproduce, and feed. With time, and as the beaver population grows, these dams get bigger each time. These animals keep cutting down trees and covering some wider areas that were inhabited previously by other species. The landscape changes, these areas get flooded permanently, most vegetation dye, the soil properties get altered, and just a few species can keep living there. The ecosystem changes.

b) Forest fire → (i) New plants can grow because of an increase in sunlight on the forest floor

This is an example of biological succession. Stable forests characterize as having big old trees that compete for light developing big canopies at heights. Poor light reaches the ground and allows some smaller species to grow. When a fire occurs, some of these trees might fall or disappear. These fire events open windows in the forest through which sunlight directly reaches the ground. Many new species can germinate and grow. There occurs a renovation of vegetable species in the forest and the consequent renovation of other living forms.  

c) Lack of rainfall  →  (ii) Zebras migrate farther to find water holes

It is not unusual that some species need to migrate looking for food or water. In certain areas, seasonal differences are very sharp, and while some periods characterize as producing plenty of food and water, some others characterize as lacking them, dry seasons especially. Animals develop different strategies to face these moments. Zebras need to migrate to find a new source of water to ensure proper hydration.

d) Invasive water plants arrive →  (iv) Sunlight is blocked for native seagrasses

A very known global environmental problem is the damage caused by invasive species. In a few words, exotic species arrive in a new area out of their native distribution range, establish, grow, adapt, and reproduce. These exotic species turn into invasive species when they overgrow, sharply increasing their reproductive rate. At this point, interaction with native species becomes harder, competing for resources such as space, light, food, shelter, water, among many others. Invasive species become such a good competitor that end by displacing native species. In the exposed example, invasive water plants arrive, and their population overgrows. They compete for light with native seagrasses and end by blocking it for them.

e) Grasshopper outbreaks  →   (v) Crops are wiped out along the prairie

This is an example of the prey-predator relationship. In this case, grasshoppers are the predators, and crops are acting as the prey. Whenever one of the population increases in size, the other one follows this increase, causing the decrease of the first one. When the first population decreases, the second one also decreases. In this example, grasshopper outbreaks, meaning an increase in predation rate over crops. Many more individuals are feeding on the crops, causing more damages to the plants´ population. Crops do not have enough time to recover, so they are wiped out.

f) Coyote disease decreases the population →  (vi) Mice population explodes

This is also an example of the prey-predator relationship. In this case, coyotes are the predators, and mice are acting as the prey. As coyotes are affected by the disease, which causes a decrease in their population size, mice seem to be favored, as they are not predated. They have enough time to recover as a population and increase in size. Coyotes´population decreases in size, so there are many fewer individuals feeding on mice, and hence, the mice population increases very fast. It explodes.

Answer:

7.5mL

Explanation:

Comsidering the definition of dilution, 7.5 mL of the stock solution  of 2 M are required to prepare 100 mL of 0.150 M solution.

Dilution is a procedure by which the concentration of a solution is lowered. It is achieved by adding more solvent to the same amount of solute.

Then the amount of solute does not vary, but the volume of the solvent does: when more solvent is added, the concentration of the solute decreases, as the volume of the solution increases.

A dilution is mathematically expressed as:

Ci×Vi = Cf×Vf

where

In this case, you know:

Replacing in the definition of dilution:  

2 M×Vi= 0.150 M×100 mL

Solving:

[tex]Vi=\frac{0.150 M x 100 mL}{2 M}[/tex]

Vi= 7.5 mL

In summary, 7.5 mL of the stock solution  of 2 M are required to prepare 100 mL of 0.150 M solution.

The statements that are true about the esophagus are:

The esophagus is the muscular tube of the digestive tract that develops from the pharynx to the stomach.

This part of the digestive system is traversed by food, which enters through the mouth, passes through the pharynx, crosses the esophagus and reaches the stomach.

In this process, the esophagus has an active participation, since its walls contract to promote the advance of the food.

Therefore, we can conclude that the esophagus is a muscular tube that moves food from the mouth to the stomach.
