Answer:
Cohesion
Explanation:
Water molecules have extremely strong cohesive forces, meaning they are heavily attracted to each other. This is due to their ability to form hydrogen bonds, which is a particularly strong intermolecular force.

Fishing is a major part of many Caribbean economies. The yellowtail snapper and
Nassau grouper are important food fishes. However, a lack of adequate regulation
has led to overfishing in many areas and consequent damage to reefs.
When grouper fishing is set to 70% what happens to the population of others fish
populations in the reef?
Answer:
The reef collapses.
Explanation:
The variety of life in the Caribbean makes up the reefs and when they are taken away by the fishermen and leaving the areas without fish population the population of other fish also declines and it impacts the reef formation and growth. The corals cannot survive with them and thus collapses the entire marine ecosystem.The 4 different types of microorgansisms?

Based on the graph, at what temperature does this enzyme work best? * Captionless Image 47 C 30 C 40 C 15 C
The enzyme works best at optimum temperature. They will best at 37 degree celcius.
What is the optimum temperature?Enzymes function best between 20 and 35 °C. At very low temperatures, they become inactive, and at very high temperatures, higher than 45°C, they get denatured, or destroyed.
A greater rate of collisions between enzymes and substrates may result from increased molecular activity brought on by temperature increases.
However, if the temperature increases too much, the enzymes may become denatured and the beneficial benefits of the temperature increase may be reversed.
Therefore, The enzyme works best at optimum temperature. They will best at 37 degree celcius.

Why are ions important to metabolism?
A.) Some enzymes turn ions into substrates.
B.) Some enzymes require specific ions to work.
C.) Ions are not important to metabolism.
D.) Some enzymes break down into ions.
Answer:
Your answer is B
Explanation:
Ions play an important role in the metabolism of all organisms as reflected by the wide variety of chemical reactions in which they take part.
Ions are important to metabolism because some enzymes require specific ions to work. Thus, the correct option is B.
What is Metabolism?Metabolism may be defined as a set of methodologies that involves gradual and continuous chemical alterations that take place inside the cell or the body of an individual in order to stimulate the rate of survival.
Metabolism is also characterized as the sum of the chemical reactions that occurs within each cell of a living organism in order to furnish energy for vital processes.
Ions are an inorganic form of molecules that are loosely associated with the enzyme in order to ensure its effective function. Ions like [tex]Na^+, Mg^2^+, Ca^2^+[/tex], etc. are most prevalent.
Therefore, ions are important to metabolism because some enzymes require specific ions to work. Thus, the correct option is B.

Explanation:
DNA is the chemical name for the molecule that carries genetic instructions in all living things.
Deoxyribonucleic acid is a molecule made of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth, and reproduction of all known organisms and many viruses.
How is ADP converted to ATP?
- by the addition of one phosphate molecule
- by the addition of one adenosine molecule
- by the removal of one phosphate molecule
- by the removal of one adenosine molecule
Adenosine diphosphate (ADP) has been the organic compound involved in metabolic reactions. It makes ATP by adding one more phosphate molecule. Thus, option A is correct.
What are ADP and ATP?ADP is the abbreviation for Adenosine diphosphate, an important organic molecule that is crucial for the cellular and metabolic process and to make ATP. It is composed of one adenosine, two phosphates, and one sugar molecule.
ATP, on the other hand, is Adenosine triphosphate the most important organic molecule for the living cell that provides energy to drive the various activities and functions in the body. It has been comprised of one adenosine, three phosphates, and one sugar molecule.
The conversion of ADP to ATP is shown as ADP + Pi + energy → ATP
Therefore, option A. addition of one phosphate to ADP converts it to ATP.

Calculate to average diameter for each bubble solution. Super bubble=____cm regular bubble soap____cm
Use the results on the chart
The average diameter of superbubbles is 15.1 cm and the average diameter of regular soap bubbles is 11.5.
What is meant by average value?
The mean obtained by obtaining the ratio of the sum of total values in a set of data and the total number of values in a given data is called the average of the data.
The formula for average had several applications. The average number of people suffering from a disease can help in the study of the disease.
The average is calculated by finding the sum of numbers and dividing it by the total values of numbers.
Thus
The average diameter of superbubbles =
[tex]\frac{15+10+12+18+22+13+16+18+15+12 }{10} = 15.1[/tex]
The average diameter of regular bubbles =
[tex]\frac{10+5+16+11+12+11+15+15+6}{10} =11.5[/tex]
Therefore, the average diameter of superbubbles is greater than the average diameter of regular bubbles.

As a solute concentration rises, its rate of transport through a membrane increases up to the point where all the carriers are saturated. This point of saturation is called what
Answer:
transport maximum
Explanation:
In the context of physiology, this point of saturation is called the transport maximum. Like mentioned, this is the point in which any further increase in the concentration of a substance no longer results in an increase in movement of that substance across a cell membrane, thus indicating that the carrier of that substance is completely saturated and can no longer complete its function.

Matt makes $80 a month mowing lawns. His friend James also mows lawns, but he makes x dollars less per month than Matt does. James makes a total of $816 per year. How much less each month does James make than Matt?
Equation: 12(80 – x) = 816
Solve the linear equation to find the value for x.
x =
How much does James earn each month?
Remember that x represents how much less per month James makes than Matt.
Answer:
The data is:
Matt makes $80 per moth.
James makes ($80 - x) per month.
James makes $816 per year.
Now, a year has 12 months, then we have that:
($80 - x)*12 = $816
With this equation we can find the value of x.
so we must isolate x in one side:
($80 - x)*12 = $816
$80*12 - x*12 = $816
$960 - x*12 = $816
x*12 = $960 - $816 = $144
x = $144/12 = $12
Then james makes $12 less than Matt each month, this means that James makes:
J = ($80 - $12) = $68 per month.
Answer:
X= 12
$68
