The macromolecules are mostly composed of carbon, oxygen, and a hydrogen atom. The carbohydrates contain these atoms in the ratio of 1:2:1 represented by the formula .
Further Explanation:
The carbohydrates and lipids are identified by using the C:H:O ratio but lipids have very low oxygen content as compared to the carbohydrates. The proteins also contain sulfur and nitrogen along with carbon, oxygen, and hydrogen. The carbohydrates are composed of water and carbon dioxide by the photosynthesis process in the plants. The components like potatoes, vegetables, cereals, and fruits contain carbohydrates.
The carbohydrates are divided into monosaccharides, polysaccharides and disaccharides depending on the carbon chain length. The simple sugars or monosaccharides provide energy to the cell as they breakdown and produce ATP. These are fructose, galactose, and glucose. The disaccharides consist of two units of monosaccharide that are linked together through a dehydration reaction. In this reaction, a water molecule is released as the hydrogen of one monosaccharide binds with the hydroxyl (-OH) group of another monosaccharide forming a glycosidic linkage. For example, glucose combines with another glucose to form maltose. Other disaccharides are sucrose (glucose + fructose) and lactose (glucose + galactose).
The polysaccharides such as starch and glycogen are storage polymers which are stored as an energy source respectively in plants and animals. Starch is stored in the seeds to provide food to the developing embryo. Glycogen is used by humans and animals as a source of energy and is cleaved into respective glucose units through digestive enzymes before its conversion into ATP. Chitin and cellulose are also polysaccharides that help a cell in providing the structural support.

True statements: A (Water is made up of atoms bonded to form molecules) and D (The chemical formula for water is H₂O).
False statements: B (Water contains half as many hydrogen atoms as oxygen atoms) and C (Water molecules tend to push away from each other)
Let's examine each statement to determine its accuracy:
A) Water is made up of atoms bonded to form molecules.
True: Water is indeed composed of molecules. Each water molecule consists of two hydrogen atoms covalently bonded to one oxygen atom, forming the H₂O molecule.
B) Water contains half as many hydrogen atoms as oxygen atoms.
False: The chemical formula for water, H₂O, indicates that there are two hydrogen atoms for every one oxygen atom in a water molecule. Therefore, water contains twice as many hydrogen atoms as oxygen atoms.
C) Water molecules tend to push away from each other.
False: Water molecules exhibit a property called cohesion, where they are attracted to each other due to hydrogen bonding. This attraction causes water molecules to "stick" together rather than push away from each other. It's why water forms droplets and has a relatively high surface tension.
D) The chemical formula for water is H₂O.
True: The chemical formula H₂O accurately represents the composition of water, indicating that each water molecule consists of two hydrogen atoms and one oxygen atom.
The structure of water involves H₂O molecules, with each molecule consisting of two hydrogen atoms and one oxygen atom, and water molecules exhibit cohesion due to hydrogen bonding, causing them to attract and stick together.

Option A, at mid-ocean ridges, is the correct answer.
The topmost layer of the nautical share of a tectonic plate is known as the Oceanic crust. The Ocean Ridge is created as an effect of raising up of magma from the asthenosphere. Mid-ocean ridges are a large, seismically activated submarine elevation system located in the center of the basin of an ocean and considering the situation of the up-welling of magma connected with seafloor expanding. Thus they are as thick as 6 Km at the mid-ocean ridges.
The oceanic crust is thickest at the mid-ocean ridges.
Further explanation:
Oceanic crust is a thin crust that separates the ocean from the mantle, which is present beneath them. The tectonic forces create and destroy the earth's crust. This cycle is essential for all life processes. It helps in forming the earth's crust we walk on and the crust present in the ocean.
Oceanic crust is also known as seafloor. It is denser, thinner, and simpler in structure than the earth's crust. Their fragments become stranded high and dry on top of the continent because of uplift. It is made up of igneous rock basalt. It is formed from the larva that tends to flow smoothly. The basic component of the basalt is magnesium silicate; that is why; it is also known as mafic.

If you run an experiment with multiple variables, you won't be able to determine which variable ultimately led to the change.
What is the one variable at a time in an experiment?
Testing a single variable at a time enables you to assess the outcomes of your experiment to see how much a particular adjustment influenced the outcome.
If you test two variables simultaneously, you won't be able to determine which one caused the outcome.
Only one variable (the independent variable) is altered at a time in a science experiment to see how it affects the dependent variable.
Other variables that are either constant or vary throughout the experiment but are not thought to impact the results may also be measured by the researcher.
Therefore, scientist use to test just one variable at a time in an experiment.
