Answer:
the cell was submerged in a hypotonic solution
Explanation:
The cytoplasm pulled away from the cell wall because the elodea plant is submerged in a hypertonic solution.
The plant elodea contains cell membrane and cell wall.
The cell wall is an elastic structure that is permeable to all molecules.
The cell membrane is however, selectively permeable.
For the plant to survive and function well, the fluid its submerged into must be isotonic or be able to maintain an osmotic balance.
When placed in a hypertonic solution, a strong concentration, exosmosis occurs.
Water flows out of the cell into its surroundings.
As a result, the vacuole shrinks and eventually pulls the cytoplasm from the cell wall.
Therefore, the cytoplasm pulled away from the cell wall because the elodea plant is submerged in a hypertonic solution.

Answer:
During passive transport, substances travel with the concentration gradient.
During passive transport, substances travel with the concentration gradient.
What is passive transport?Passive transport is defined as the type of the membrane transport that has to be required energy that has to move the substances just across the cell membrane. In place of using the cellular energy just like in the process of the active transport as well as passive transport that relies on the second law of the thermodynamics that has to drive the particular movement of the substances just across the cell membranes.

Which of the following would be considered a competitor or Corals and a direct threat to coral reefs?
Zooxanthellae
Green Algae
Crown of Thorns Sea Star
Coralline Red Algae
Rainbow Parrot Fish
Answer:
Rainbow Parrot Fish
Explanation:
Rainbow Parrot Fish is an herbivore and it is considered as competitor of corals and a direct threat to coral reef because Rainbow Parrot Fish majorly source of feed is algae which result in missing of lots of algae in corals colony. They consume most of the coral in the coral reefs with their beak like teeth therefore resulting in competition and not enough available algae source for corals. After feeding on algae , they also graze on corals in Coral reefs.

In parts of the Northern Hemisphere grasslands, the spring growing season is becoming two weeks longer than in the second half of the 20th century. The spring growing season is now coming earlier in both hemispheres. Based on the above statement and the following graph, what conclusion can be made regarding temperature?
Answer:
Natural Earth cycles result in increased temperatures
Explanation:
By temperature looking te the graph we can see that there is a soft increase in temperature from 1880- 1940. It seems that from 1940-1980, the temperature was stable, but since 1980 there is a noticeable temperature increase, until the year 2000. By year there are increases and decreases in temperature, which correspond to the different seasons and temperature cycles over the year, but in a general vision, the temperature is obviously increasing with the pass of years.
According to the statement, the spring growing season is becoming longer than in the second half of the 20th century, and it is coming earlier. This is reflected in the graph from the year 1980 to 2000.
According to the graph and the statement, we could estimate what is going to happen in the next years is there is no change. Although, we can not predict it for sure.

Aquarium salt water is prepared to a salinity of 30 ppt (parts per trillion) by dissolving 3.26 kg of salt into 114 L of water. If you wanted to make 4,000 mL of salt water at the same salinity, how many grams of salt will you need?
Answer:
114 gram of salt is required.
Explanation:
Below are the following given data in the question:
Prepared salinity water = 30 ppt
Weight of salt used = 3.26 kg
The volume of water = 114 L
Below is the calculation.
4000 mL = 4000/1000 = 4L
Let the used = x kg
3.26/114 = x/4L
Now solve for the x.
x = 0.114 kg or 114 gram
CONCLUSIONS: Genetic counseling is useful in predicting the probability of a child being born with a Mendelian inherited trait. Sickle cell anemia is caused by a recessive allele. A couple would like to know the chances of their child having sickle cell anemia. Parent #2 has the disease; parent #1 does not. Based on phenotype, parent #2 would have the genotype, ss. Parent #1 could be genotype, SS or Ss. Punnett Squares have been set up for crosses using both possible genotypes of parent #1. Should the couple be concerned that their child may have sickle cell disease? Why or why not?
Answer:
Yes, if parent 1 is Ss then there is a 50% chance the child will have it.

Pure liquid water has pH of 7 which means that water is
Answer: neutral
Explanation: The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.
Answer:
pH is a measure of how acidic/basic water is. The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity,

He makes many friends with members of the community while doing his research. Whenever he can, he seeks to understand how his friends feel about the events of their day-to-day lives. When he returns back to Las Vegas, he writes a book emphasizing his friends' points of view. He tries to write the book so that, if his Kpelle friends read the book, they would understand the situations and feelings he is talking about. What kind of anthropology is he performing? Mark all that apply.

Drag each tile to the correct location not all the labels will be used identify the phases in the lifecycle of small and big stars
Answer:
Here's an explanation instead:
Explanation:
ALL STARS BEGIN IN A STELLAR NEBULA / NEBULA
Depending on how much mass the star has, it changes what path of life cycle it will take. Low mass or average mass stars become an average star, also called a main sequence star. It swells after millions of years into a Red Giant which is GIANT. Many many many years later, it becomes a planetary nebula, and finally becomes into a white dwarf.
If the star has a large mass, it is classified as a massive star, and also goes through a form of main sequence. It swells into a MASSIVE GIANT TREMENDIOUSLY LARGE AND UNNECCESSARILY BIGGO star called Red Supergiants. After millions and billions of years, it becomes a Supernova, which finally becomes a black hole if the outer layers literally get blown off into space and the core collapses and gets compacted into incredibly dense Nano-Googleplex sized molecules. If it doesn't, it becomes a cool Neutron Star.
I cannot drag tiles around, because there is no tiles or labels, however, I hope you get the point from this weird answer.
