how might a carrying capacity of a coastal ecosystem change as the result of a tsunami? Explain using one or more examples
Answer:
The carrying capacity for one or more species could decline.
Explanation:
The carrying capacity for one or more species could decline for a few reasons,
1. because of the destruction of habitats
2. With the destruction of habitats the animal who find shelter within them will decline , predators eat the prey who take shelter in those habitats so with the prey's decline the predator number will decline as well.
A tsunami affects the carrying capacity by altering the ecosystem equilibrium. It causes a lack of food, shelter, and freshwater. It changes the ground pH, salinity, and 0xygen levels. Populations eventually decline.
----------------------------------------------
The carrying capacity might be affected by different factors, known as limiting factors, which might be a result of the population density (for example, competition) or might be density-independent. This last case refers to dense-independent factors, and among these, we can mention human impact or natural disasters (fires, volcanic eruption, flooding).
Natural disaster causes damages in an ecosystem, reducing the available resources such as food or shelter, and consequently decreases the population size. Natural disasters reduce the carrying capacity of the environment.
A tsunami is an example of a natural disaster that acts as a limiting factor. The magnitude of tsunamis might cause different degrees of damages into the coastal ecosystems.
Due to technical problems, you can find further information about how the tsunami affects the carrying capacity in the attached files.

On a hot summer day, Tameka spilled water on the sidewalk, but a few hours later there was no evidence of the water. What most likely happened to the water?
A) boiling and evaporation
B) sublimation and vaporization
C) boiling and sublimation
D) vaporization and evaporation
Answer:
d
Explanation:
because the sun dried up the water which is making it get so hot it just evaporates into a gas
D
Vaporization is the transitional phase of an element as it changes from a liquid phase into a gas phase at a point greater than the boiling point. Evaporation is the transition from the liquid phase to the gas phase that takes place below the boiling temperature.
Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. The surrounding gas must not be saturated with the evaporating substance. When the molecules of the liquid collide, they transfer energy to each other based on how they collide with each other.
They BOTH turn into GAS

Whales were hunted nearly to extinction primarily for their blubber, which was burned in oil lamps to light buildings. Whale oil lamps have been replaced by electric lighting, but the survival of the western North Pacific whale population is not guaranteed. Do you think it could be ethical to hunt a species to extinction to meet the needs and wants of human society?
Answer:
This is unethical.
Explanation:
Every creature contributes one way or the other to the existence of ecosystem,and the stabity of the biodervasity. The whale is one of the major componets of the aquatic biodiversity .Therefore continous killing whch may lead to extinction would distablized rthe bioderstiy and leads to the loss of ecosystem.
Besides,if whales goes into exticntion this would affet the future generations to learn from their existence?Therefore for preservation for future generations,they must be protected for extictinon.
The advent of biotechnology,has shown the genetic products of human and animals could be used to produce genetically modifjed product for humanity Thus if whale goes into exticntion this may not be possible.
How does an enzyme influence a chemical reaction
A. It provides the substrate needed for the reaction to occur
B. It raises the activation energy so that a reaction can occur
C. It speeds up the reaction rate
D. It is used as a reactant to form the product
Answer:
It speeds up the reaction rate
Explanation:
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
Enzyme actually raises the reaction rate to make the product sooner than before by lowering the activation energy, the correct option is C.
What are enzymes?An enzyme is a compound that acts as a catalyst in life forms, regulating the rate at which chemical reactions occur while remaining unaffected.
Substrates are molecules on which enzymes can act, and the enzyme converts the substrates into distinct molecules known as products.
While working in any chemical reaction, enzyme usually lowers the activation energy, means the minimum energy required to complete the transformation of reactant into products, so that the reaction will get speed up.
Thus, the correct option is C.

Answer:
True
Explanation:
Is the space between the particles slay the same when thermal energy is added to the material?
Answer:
No
Explanation:
When thermal energy is added to a material ,kinetic energy increases causing the molecules to begin to move faster. When these particles move faster, more space is created because there is more energy to overcome the intermolecular forces, which causes the distance of the molecules to increase. This is why a liquid can become a gas (evaporation) the increase in thermal energy increases the movement of the molecules and they overcome the forces that hold them together, causing the distance between each particles
When electrons are shared, the type of bonding is called _____.
hydrogen
covalent
ionic
nuclear
Answer:
Covalent
Explanation:
A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms.
Why do atoms form bonds with each other
Answer:
Atoms form chemical bonds to make their outer electron shells more stable. ... An ionic bond, where one atom essentially donates an electron to another, forms when one atom becomes stable by losing its outer electrons and the other atoms become stable (usually by filling its valence shell) by gaining the electrons.
Explanation:
The population would be most likely to remain at the level shown at Q under which of the following conditions?
a) All predators are eliminated.
b) Euglena is a primary producer.
c) Environmental conditions do not fluctuate.
d) Environmental conditions do not fluctuate.
Answer:
B Euglena is a primary producer.
If environmental conditions stayed constant as they are indicated at Q, the people would most likely stay there. So, the correct option is D.
What are environmental conditions?Environmental factors include the physical, chemical, and biological elements that have an impact on an ecosystem's species' ability to grow, develop, and survive. Temperature, water accessibility, sunlight, soil pH, nutrients, and the presence of other species are a few examples of environmental factors.
The abundance and distribution of many species throughout an ecosystem can be significantly influenced by these variables, which can change over time and space. Depending on the precise characteristics of the environment and the population dynamics at play, the population at level Q in the example given above may remain stable under a variety of circumstances.
Therefore, the correct option is D.

how many chromosomes would each of these sex cells have before they come together and create a cub?
Answer:
Haploid number of chromosomes.
Explanation:
Before fusion of sex cells i. e. sperm cells and egg cells, there are half number of chromosome present in each sec cell because in the sex cells meiosis occurs. Meiosis is a type of cell division in which a single parent cell divides into four daughter cells having haploid chromosome i. e. half number of chromosomes in each daughter cell. So when these sex cells fuse together, they form a diploid organism.

In the early 19th century, rabbits were shipped from Europe to Australia. These non-native rabbits rapidly became invasive due to little competition for food and relatively few predators in the introduced regions. Which of the following explains the effect humans most likely had on the ecosystem by introducing this non-native rabbit species?
Answer:
decrease in population of the prey and an increase in rabbit population
Explanation:
The prey were constantly being killed and eaten by rabbits so there was a decrease in their population whilst the rabbits had an increase in their population due to there being more food for the to live on and there being less competition.

A patient is brought into the emergency room. She is unconscious and is dehydrated. Will she be given an intravenous solution IV that is hypertonic, hypotonic or isotonic to her red blood cells? Explain your answer. Remember that pure distilled water would be hypotonic to blood cells.
Answer:
The correct answer would be - isotonic drips.
Explanation:
As it is known that water is hypotonic to the RBCs of blood and RBCs have no other membrane, like cell wall so due to osmosis the water will get in the cell and will expand it until it gets burst. So, hypotonic drip should not be given to the dehydrated patient.
Hypertonic drip will leads, to the cell water to gets into the bloodstream due to osmosis. It will be the same as consuming seawater which will increase dehydration in this patient.
Thus, the correct answer would be - isotonic.
