Answer:
K I'm not sure about this one, but it should be capillary action
Explanation:
This is because cohesion and adhesion have to do with water stick to surfaces. Capillary action occurs because of how the water sticks and bonds to certain surfaces. Cohesion is how water molecules stay together, while adhesion is how water molecules are attracted to other molecules.

despite being very different of diets that include different types of food containing different levels of biomolecules, these diets are all able to support human being in living. How is this possible?
Answer:
As nutrients, protein is overemphasized and carbohydrates are underrated in terms of their importance in our diets. Most people in the United States now eat more protein than their bodies need, and, somehow, carbohydrate-rich foods such as potatoes and bread have gotten a bad name for being fattening. Yet protein from animal sources often comes in foods that contain significant amounts of saturated fatty acids. And the only carbohydrate-rich foods that are truly fattening are those laden with fats and added sugar, such as pastries, cookies, and baked potatoes heaped with sour cream.
In fact, there is some evidence that diets high in carbohydrates may help reduce the risk of heart disease. Thus the Eat for Life guidelines suggest not to eat any more protein than you already do and to increase the amount of carbohydrates you eat to compensate for the lower amount of fat that your diet will contain.
This chapter presents the evidence that increasing the proportion of carbohydrates in the usual American eating pattern at the expense of fat will tend to lower chronic disease risk. It also discusses some of the health claims made for dietary fiber, a group of substances that are made up mostly of complex carbohydrates.
2. If a cell has a very large amount of ribosomes attached to its rough
endoplasmic reticulum, what is the cell probably specialized to manufacture?
Answer:
Protein
Explanation
Ribosome and Rough E.R are organelles in the cell.
E.R are extensive membranes (which are continuous with the nuclear membrane) that exist as flattened compartment in the cytoplasm.These compartment form sacs in the cytoplasm. The sacs are interconnected with one another to form a complete system called the reticulum.
Based on structure two types of E.R exists -the Smooth E.R and the Rough Endoplasmic reticulum.The later is called rough because of Ribosomes attached to its outer membrane. the smooth lacks ribosomes attachment on its outer membrane. Ribosomes are the site of Protein synthesis in the cell.
They are small in number and are made up of RNA and protein.Generally the protein synthesised in the Ribosomes,are moved into the sacs in the R.E.R,where they are modified.They are eventually budded off in vesicles which form the Golgi bodies

A water molecule is polar because there is an uneven distribution of electrons between the oxygen and the hydrogen atoms. Therefore, the correct option is A.
A water molecule (H₂O) consists of two hydrogen atoms linked to one oxygen atom.
The electronegativity of oxygen is 3.44 which is higher than the electronegativity of hydrogen, which is 2.2. As a result, it tends to pull the shared electrons towards itself, because of which it acquires a partial negative charge and the hydrogen atoms acquire a partial positive charge.
As a result of unequal sharing of electrons, a dipole moment in the molecule is created, making the water molecule polar.

How does a chameleons tongue keep the flys on
Answer:
Once the tongue makes contact with a prey, the prey gets attached to the sticky tongue like glue. The chameleon then withdraws its tongue, with the prey firmly attached into its mouth. The chameleon's sticky tongue is capable of gripping anything – sometimes even lassoing lizards nearly the same size as itself.
Explanation:
You want to test which size of soccer (football) ball is easiest to juggle with your feet. You test a size 3, size 4 and a size 5 ball. You count the seconds the ball stays in the air for each of the trials. You allow yourself to use both of your feet, knees, and head to juggle the ball. a. Independent Variable: b. Dependent Variable: c. Control Variable:
Answer:
independent variable: size of soccer ball
dependent variable: period of time the balls stay in the air
control variable: parts of the body used to juggle the ball
Explanation:
The independent variable is the manipulatable variable supplied into an experiment. It is a variable that directly affects the dependent variable.
The independent variable is the outcome variable. It is the variable that is primarily measured from experiments whose value depends on the value of the independent variable.
The control variables are those that are kept constant throughout the course of experiments. In other words, they do not directly affect experimental outcomes.
Hence, in the illustration;
independent variable: size of soccer ball
dependent variable: period of time the balls stay in the air
control variable: parts of the body used to juggle the ball

What biomolecule determines whether an individual inherits the inability to produce the enzyme needed to break down the amino acids
Answer:
NUCLEIC ACIDS
Explanation:
Four biomolecules are found in living systems and they are responsible for every process undergone by cells of living organisms. Nucleic acid is one of the four biomolecules, which is the precursor of another biomolecule called PROTEIN.
DNA and RNA are the two nucleic acids which contains segments called GENES that encodes the information needed for the synthesis of proteins and transfer of this information to offsprings. Genes found on nucleic acid biomolecules undergo expression to produce proteins. ENZYMES are proteinous molecules that catalyse biochemical reactions in living systems.
From the explanation above, this means that ENZYMES that catalyze reactions like breaking down amino acids are PROTEINS, which in turn are made from GENES carried by NUCLEIC ACID biomolecules.
Therefore, NUCLEIC ACIDS determine whether an individual inherits the inability to produce the enzyme needed to break down the amino acids

Abiotic conditions would be the temperature of the reef, and also the amount of light that the living organisms receive. (aka coral and zooxanthealle algae)
Biotic would be coral, and also fish. A disturbance in the balance of an abiotic of biotic factor could in turn kill one of the many organisms needed to keep each other alive in symbiosis within the coral reef. In a domino effect, if one organism that is essential to the balance dies, then another, and so on until the coral reef itself dies.

Explanation:
1. The crisis the people in cape town were facing was a major drought that affected animals, plants, and people.
2. The crisis was caused by 3 years of barely any rainfall and the people using the same amount of water they had been using for a while. Naturally, things caught up and the people were using to much water without enough to supply.
3. The government and local authorities started setting laws to restrict water usage. So businesses and citizens had to restrict water usage very quickly. At one point they said they would run out of water completely, that made reality set in for people. People started setting out separate buckets and jars to collect water for drinking, bathing, and watering their plants for food. Everyone stopped using their baths.
People removed eucalyptus trees so water would start running down the dams.
Businesses had to manage the water even more carefully, they had to make sure that how much water they were using was under the limit but still accommodating either the plants or the people or the animals.
4. The crisis was ultimately resolved when the rain came again and people kept their same restrictions for a little bit to catch up and then they started getting more water gradually but still making sure they weren't using too much.
5. Now that the crisis is over, I think it will have have a lasting impact on the people of Cape Town. I think mentally it made them more aware of what could happen and made them more precarious. I think if there was less rainfall for a bit again they would start going into preparation mode, but this time, know more about how to reverse it and live with it. Like in the video, it showed the hotels, people, and businesses have started monitoring the water usage again and installing things to catch extra water and making sure there is a backup water containers to avoid this in the future. I also think because of all the restrictions it will affect the land for quite a while, you can't just replant trees and vegetables, and regrow all the foods businesses produced with a snap of a finger, it takes time, seasons, months, so consequently as the land is affected so are the people.
I think the crisis affected the people's mindset by changing their outlook on water and showed them how to be more frugal with water.
