Sugar
Explanation:
Sugar goes into your blood and gives you a quick energy boost.
Answer:
Carbohydrates
Explanation:
Carbohydrates provide energy to the body, particularly through glucose, a simple sugar that is a component of starch and an ingredient in many staple foods. Carbohydrates also have other important functions in humans, animals, and plants. Lipids include a diverse group of compounds that are largely nonpolar in nature.
Read the scenario and examine the table.
Ivan wants to test how the amount of water consumed each day affects the number of facial blemishes people receive over a month. He gathers 12 people and divides them into 3 groups. He keeps everything the same for each group except for daily water and food intake. Throughout the month, Ivan tallies the number of facial blemishes each individual receives. The table details how Ivan changed the independent variables for each group.
Note: Group 1 is Ivan's control group.
What error did Ivan make in the design of his investigation?
A.) Ivan did not record the results for the dependent variable in a data table.
B.) Ivan did not determine the average number of blemishes received.
C.) Ivan tested more than one independent variable at a time.
D.) Ivan had the individuals in the control group consume water.
The answer is C.) Ivan tested more than one independent variable at a time.

1. Why is it advantageous for scientises to test only one variable at a time during an experiment? 2. Distinguish between a variable and a control. 3. What is differentiation? 4. What are some advantages ande disadvantages of light microscopes and electron microscopes? 5. Explain why you cannot draw a conclusion about the effect of one variable in an investigation when the other key variables are not controlled.
Answer:
It is advantageous because the fewer variables are presented, the simpler the investigation and the more concrete the hypothesis will be.
A variable is that quantitative data that is modified or varies over time, it must be quantifiable, reasonable, and its variability must be expressed by means of indices, while the control group is the group that is controlled and compared. with other research groups to be able to relate cause-effect or risk factors by exposing them to the agent of the problem, while the researcher observes.
Differentiation is the process by which it is sought to find the differences in the investigation.
The advantages of electronic and optical microscopes is that we can observe very small beings, such as microbiological, or infected tissues, or even tissues to evaluate their histological architecture, they are very important for science and the medical professions, they are adjustable before different cephalometric morphologies, In other words, they can be adapted according to the size of the user to make it more comfortable.
The disadvantages are that the optical microscope cannot see very small microorganisms, such as some viruses and bacteria, and also has much less definition and sharpness than the electronic one, its costs are high, its CORRECT use is difficult to learn and teach, maintenance it is rigorous and delicate.
If the other variables are not controlled, then all the variables would be a possible cause or effect factor of a conclusion, that is, if we do not control the variables, we cannot propose a certain conclusion, effects or hypothesis, since the risk of The error is very high and the conclusions obtained from the uncontrolled variables will have little certainty or credibility.
Explanation:
Ls variables in an investigation can be dependent or independent.
It depends on the role they fulfill in the research, they can also be classified as homogeneous or heterogeneous, provided that one raises a main problem, a solution tree, takes into account variables that are selected to be able to face in the research. These investigations must be homogeneous, in order to provide more certainty in the hypothesis or in the conclusion.
That a variable is homogeneous means that it covers most or all the variances of a population, and is the most comprehensive or representative in a logical and reasonable way to what you want to investigate.

Explain why there is a climatic difference between the cities of anchorage, Alaska, and Kingston, Jamaica.
Answer:
mainly due to the differences in latitude
Explanation:
Latitude can be defined as geographic coordinates that indicate the location north-south of a given point on the earth, which is expressed by angular distances ranging from 0° at the Equator to 90° (either North or South) at the poles. The differences in latitude also indicate differences in the amount of sunlight, thereby having a critical role in determining a region's climate. Geographic places located at high latitudes receive less sunlight than those at low latitudes, and, therefore, Alaska is colder than Jamaica.
Which sample was most likely DNA?
Answer:
Hydrogen, Phosphorus, Nitrogen
Explanation:
Hoped this helped have a good day, brainlist?
Hydrogen, Phosphorus, Nitrogen was most likely DNA.
What is DNA?Humans and nearly all other species carry their genetic information in DNA, also known as deoxyribonucleic acid. The DNA of an individual can be found in almost all of their cells.
The majority of DNA is found in the cell nucleus (where it is known as nuclear DNA), but there is also a tiny quantity of DNA inside mitochondria (where it is called mitochondrial DNA or mtDNA). Cellular organelles called mitochondria transform the nutrients in food into the a form that can be utilised by cells.
Adenine (A), guanine (G), cytosine (C), and thymine (C) are the four chemical bases that make up the code that stores the information in DNA (T). More than 99 percent of the 3 billion bases that make up human DNA are the same in every person.
Thus, Hydrogen, Phosphorus, Nitrogen was most likely DNA.

Your body has a layer of skin that protects it from the environment. This layer of skin is made up of many individual skin cells. Explain where all the cells came from and how two individual cells share the same traits.
Stratum Corneum This layer is composed of the many dead skin cells that you shed into the environment—as a result, these cells are found in dust throughout your home. This layer helps to repel water.
The cells of the skin layer that protects the body came from preexisting cells.
This is according to the cell theory which states that:
cells are the basic unit of lifecells arose from existing cells by reproductionall living organisms are made of cellsCells can only arise from existing cells by a reproductive process known as cell division. Cells can divide by mitosis if they are vegetative cells or by meiosis if they are sex cells.
The daughter cells produced in meiosis are usually genetically and phenotypically different from their parent cells, unlike mitosis where the daughter cells are essentially the same as the parent cells both genotypically and phenotypically.
The cells of the skin are vegetative cells. Thus, they can only reproduce by mitosis. This is why individual skin cells share the same trait.

What do human chromosomes do?Long segments of DNA are carried by chromosomes, which are organelles that can be found within the nucleus of cells. The material that houses genes is called DNA. It serves as the base for the human body. Additionally, protein found in chromosomes aid in the appropriate structure of DNA.
What are chromosomes and what do they do?The highest possible level of both protein and DNA organization is seen in chromosomes. Chromosomes' primary mission is to carry DNA & pass genetic material from one generation to the next. Cell division involves the critical function of chromosomes. They guard against tangles & damage to the DNA.

4. The shading around the molecule represents the relative density of electrons shared by the atoms.
What does this indicare about the density of electrons around the oxygen atom as compared to
the density of electrons around the hydrogen atoms?
Answer:
Oxygen is denser than hydrogen
Explanation:
Even though the images of the electron density of each atom were not shown, the electron density of each atom depends on the number of electrons present. Since we know that oxygen has eight electrons while hydrogen has only one electron.
If the density of an atom can be obtained from relative electron densities then eight electrons on oxygen is denser than hydrogen having only one electron.
