Answer:
1 - Diffusion is when small, non-polar molecules pass through the cell membrane. It happens so that the cell can get vital nutrients, it is a type of passive transport.
2 - Osmosis is the transport of water through the cell membrane. It is a type of passive transport, the water moves to the side of the cell with less water.
3 - Facilitated diffusion is when protein channels or transports help large polar molecules like glucose that ordinarily couldn't get through the cell membrane pass through the membrane.
4 - Active transport is when a molecule requires energy, ATP, to pass through the cell membrane. An example of this is molecular pumps, the use energy, ATP, to work.
5 - Endocytosis is when a vesicle captures an outside substance for the cell. There are two types of endocytosis, phagocytosis, which is "cell eating" where the cell digests solids, the there's pinocytosis, which is "cell drinking" where the cell digests liquids.
6 - Exocytosis is when a vesicle removes a substance from the cell by combining with the cell membrane and pushing it out.
7 - The Membrane is made out of phospholipids
8 - Carrier proteins help molecules that are large and polar get into the cell.

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 Whale oil lamps have been replaced by electric lighting, but the survival of the western North Pacific whale population is not guaranteed.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.

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.

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.

Nicholas’s sand castle is 81 cm tall but the wind is blowing away sand at a rate of 3 cm per minute. Nina’s sand castle is 36 cm tall and she is adding more sand to it at a rate of 6 cm per minute. After how many minutes, x, will Nina and Nicholas’s sand castles be the same height?
Answer:
5 minutes
Explanation:
Simple way to do this is by making a graph, you can start with 81 in one column and 36 in the other column. You can then start adding rows and subtracting 3 from 81 and adding 6 to 36 each row. By doing this pattern they end up matching at row 5 and they each are 66 cm tall.

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

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.
Give an example of a thing that is living and a thing that is not living.
Why is the thing considered living and not living?
Answer:
Well a living thing is defined as in a scientific term, the ability to reproduce. Living things like humans, animal and even plants are considered living because we can reproduce, even plants by making new seeds in the plant growth process. Non living things are things that won’t be able to reproduce, like for example a rock can t reproduce since it’s not living and it just “lacks the abitlity to”.
Answer:
Plants are living things they need air,nutrients,water,sunlight. Other living things are animals, and they need food,water,space, and shelter ....... Non- living things include things that do not need food ,eat,reproduce,or breathe. A car does not eat or grow..... HOPE THIS HELPS!!!!!!!!!
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.
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.
