Answer:
Abiotic factors
Explanation:
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,

Reverse osmosis is a purification technique for water which remove unwanted ions from water through the process of osmosis
What is reverse osmosis?Reverse osmosis is a process of using osmosis to separate unwanted ions and sediments from water through a semi-permeable membrane.
The benefits of reverse osmosis include:
is very simple to set uprequires minimal maintenanceremoves most contaminantsThe disadvantages of reverse osmosis include:
it is time consuming it lowers pH of water making it acidicTherefore, reverse osmosis is a purification technique for water which remove unwanted ions from water through the process of osmosis.

Comprehensive Biology What process is used in this example?
Cells come from pre-existing cells. Cells pass genetic information as DNA via reproduction. DNA carries the blueprint for life. Changes in the blueprint lead to changes in living things. Therefore most biologists assume that all living things had a common single-celled ancestor 3.5 billion years ago.

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.

What is the relationship between the carrying capacity and limiting factors of a population?
A. The size of a population is its carrying capacity, which is set by limiting factors such as predators.
B. Limiting factors often prevent a population from growing above its carrying capacity for long.
C. A population with no limiting factors would have a carrying capacity of zero.
D.Carrying capacity is a biotic factor, while limiting factors are abiotic factors.
The answer is B. Limiting factors often prevent a population from growing above its carrying capacity for long.

C - Organic Molecules. Most carbon-based molecules are called organica molecules.
A is wrong because inorganic molecules are non-carbon-based, and carbon based molecules are not ions, so B is wrong too. D is wrong because macromolecules is does have carbon, as every living thing, but macromolecules is not another name for carbon based molecules, Therefore organic molecules is the answer.
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.

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
During passive transport, substances travel___The concentration gradient
Answer:
During passive transport, substances travel with the concentration gradient.

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.

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.
