The presence of which of the following cell structures would tell him that
the cell is eukaryotic?
A. Nucleus
B. DNA
C. Cytoplasm
D. Ribosomes
Answers
The presence of nucleus would tell him that the cell is eukaryotic.
Eukaryotic cells are all those cells in whose cytoplasms a well-defined cell nucleus can be found, which contains most of its genetic material (DNA).
In this they differ from prokaryotic cells, which are much more primitive and whose genetic material is dispersed in the cytoplasm.
Eukaryotic cell is characterized by having within it the hereditary genetic material (DNA) of the organism and by having a complex structure composed of organelles that fulfill different essential functions in the cell.
Cell nucleus being the cell structure that contains the genetic material of the living being (DNA), and it is where the various functions of the cell are controlled and regulated and is covered by a nuclear envelope.
Therefore, we can conclude that the eukaryotic cell is one that has a defined nucleus, the cell nucleus is the cellular structure that distinguishes it from prokaryotic cells, where cellular activities are governed.

What is Plant cell?Plant cell is the basic unit of all plants. Plant cells are eukaryotic in nature. They have a membrane-bound nucleus and organelles. Plant cells have a cell wall surrounding the cell membrane.
The cell wall has many functions on which the life of the plant depends. Plant cell walls are composed of cellulose, which distinguishes them from other organisms with cell walls, such as bacteria (peptidoglycan) and fungi (chitin). Algal cell walls are similar to those of plants, and many contain specific polysaccharides that are useful for classification.
Examples of plant cells include different specialized cells like parenchyma, sclerenchyma and collenchyma cells.
Thus, Vacuole is most likely responsible for whether or not a plant cell is flaccid or turgid. So, the correct option is (A).

Answers
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

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

What biomolecule determines whether an individual inherits the inability to produce the enzyme needed to break down the amino acids
Answers
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

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?
Answers
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.

Answers
Answer:
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.

Answers
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.
