Cellobiose is properly categorized as a heterodisaccharide sugar, as it consists of two glucose units linked together through a β-1,4-glycosidic bond.

The correct answer is option C.

The above carbohydrate, cellobiose, is properly categorized as a heterodisaccharide sugar. A heterodisaccharide is a type of carbohydrate composed of two different monosaccharide units joined together by a glycosidic bond. Cellobiose consists of two glucose molecules linked together through a β-1,4-glycosidic bond.

To understand why cellobiose is classified as a heterodisaccharide, let's break down the options provided:

A. Heteropolysaccharide sugar: Heteropolysaccharides are complex carbohydrates composed of different types of monosaccharides. However, cellobiose is a disaccharide, not a polysaccharide, and it consists of two identical glucose units, making it a homodisaccharide rather than a heteropolysaccharide.

B. Homopolysaccharide sugar: Homopolysaccharides are carbohydrates made up of repeating units of the same monosaccharide. Since cellobiose is composed of two glucose units, it is not a homopolysaccharide.

C. Heterodisaccharide sugar: Heterodisaccharides are carbohydrates formed by the combination of two different monosaccharide units. In the case of cellobiose, it is formed by the linkage of two glucose units, which are the same type of monosaccharide. Therefore, cellobiose is a heterodisaccharide sugar.

D. Homodisaccharide sugar: Homodisaccharides are carbohydrates composed of two identical monosaccharide units. Since cellobiose is formed by the linkage of two glucose units, it is not a homodisaccharide.

E. Monosaccharide sugar: Monosaccharides are single sugar units and cannot be further broken down into simpler sugars. Cellobiose is a disaccharide, consisting of two glucose molecules, and is therefore not classified as a monosaccharide.

Therefore, the carbohydrate (cellobiose) is properly categorized a:  C. a heterodisaccharide sugar

Answer: Lipids consists of unsaturated fats. ↓

Explanation:

Like proteins and carbohydrates, lipids belong to the class of organic compounds. They are a collection of hydrocarbon-based macromolecules that are hydrophobic in nature. The three major families of lipids are steroids, phospholipids, and fats.

-

Vegetable oils, nuts, and seeds are examples of foods that are high in unsaturated fats.

-

At least one double bond can be found in the chains of unsaturated fatty acids. Since this is created by taking hydrogen atoms out of the carbon skeleton, unsaturated fatty acids have fewer hydrogen atoms than saturated fatty acids. Often obtained from plants or fish, unsaturated fatty acids are liquid at normal temperature. When fats are liquid, they are referred to as oils. Vegetable oils like canola oil and olive oil as well as fish oil are two excellent sources of unsaturated fatty acids.

When the carbohydrate cellobiose is digested into two glucose monosaccharide sugars (by cellulase in certain fungal species), the resulting glucose monomers are properly defined as the products

The correct answer is option E.

When the carbohydrate cellobiose is digested into two glucose monosaccharide sugars by cellulase in certain fungal species, the resulting glucose monomers are properly defined as the products.

In a chemical reaction, reactants are the starting materials or substances that undergo a change, while products are the resulting substances formed after the reaction. In this case, cellobiose is the substrate, which is the molecule that undergoes the enzymatic reaction. Cellulase is the enzyme responsible for catalyzing the digestion of cellobiose into glucose monomers.

The enzyme cellulase acts as a catalyst in the reaction, facilitating the breakdown of cellobiose into glucose. Catalysts are substances that increase the rate of a chemical reaction without being consumed or permanently changed themselves. However, in the context of the given question, the glucose monomers produced are the final result or product of the enzymatic digestion process.

Therefore, in the digestion of cellobiose, the resulting glucose monomers are correctly identified as the products (option E).

Answer: D. no natural selection

Explanation:

Fitness refers to the passing down of genetic make up based on the environmental requirements for reproduction and survival.

Answer choice A is incorrect, as large population, refers to the fact the more individuals in the population, the smaller effect of genetic drift. Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance (sampling error).

Answer choice B is incorrect, as random mating, refers to each individuals in a population have the same chance of passing on its alleles. An example of random mating includes: lions with darker fur color have the same chance to reproduce as lions with a lighter fur color.

Answer choice C is incorrect, as no mutations, refers to no changes to genes, new alleles are not introduced into the populations gene pool.

D is correct, no natural selection is when no phenotype can have a selective advantage over another - all individuals have equal fitness. And that correlates with the fitness being the same among all individuals in the population.

The correct matches are:

C. Chromosome: Chromosomes are structures within cells that contain DNA, genes, and other genetic material.

F. Nucleus: The nucleus is a membrane-bound organelle found in eukaryotic cells that contains the cell's DNA and is responsible for controlling cell functions and gene expression.

The half-life of phosphorus-32 (P-32) is  14.8 days.

N(t) = N₀ * (1/2)^(t / T₁/₂)

N(t) is the amount of the substance remaining at time t

N₀ is the initial amount of the substance

t is the elapsed time

T₁/₂ is the half-life of the substance

Initial amount (N₀) = 2 g

Final amount (N(t)) = 0.25 g

Elapsed time (t) = 42 days

We can rearrange the formula to solve for the half-life (T₁/₂):

(1/2)^(t / T₁/₂) = N(t) / N₀

t / T₁/₂ = log₁/₂(N(t) / N₀)

t / T₁/₂ = log(N(t) / N₀) / log(1/2)

t / T₁/₂ = log(0.25 g / 2 g) / log(1/2)

t / T₁/₂ = log(0.125) / log(1/2)

t / T₁/₂ = -log(8) / log(2)

T₁/₂ = -t / log(8) * log(2)

T₁/₂ = -42 days / log(8) * log(2)

T₁/₂ =  14.8 days

Answer: The pattern of starch storage is closely related to the distribution of chlorophyll in plants

Explanation:

Chlorophyll is a green pigment that helps plants to absorb light energy and convert it into chemical energy via photosynthesis. Starch, on the other hand, is a complex carbohydrate that is used by plants as a storage form of energy.

Chlorophyll is predominantly found in the chloroplasts of plant cells, which are responsible for carrying out photosynthesis. The chloroplasts are found mainly in the leaves of the plant, where they are exposed to light. Therefore, the highest concentration of chlorophyll is found in the leaves of the plant.

Starch, on the other hand, is synthesized in the chloroplasts of the plant cells during photosynthesis. The starch is then stored in different parts of the plant, depending on the plant species. Some plants store starch in their leaves, while others store it in their stems, roots, or even fruits.

In general, plants that have a high concentration of chlorophyll in their leaves tend to store more starch in their leaves. This is because the leaves are the primary site of photosynthesis and starch synthesis. However, some plants, such as potatoes, store most of their starch in their underground tubers.

Therefore, the pattern of starch storage in plants is closely related to the distribution of chlorophyll, with the highest concentrations of both found in the leaves of the plant. However, the specific pattern of starch storage can vary between different plant species, depending on their individual needs and adaptations.

The statement "a plant can show it is alive by growing" is not a testable hypothesis as it lacks specificity, a measurable variable, and conditions that can be manipulated or controlled in an experiment.

The statement "a plant can show it is alive by growing" is not a hypothesis, but rather an observation or a general statement. A hypothesis is a proposed explanation or prediction that can be tested through experimentation or observation.

To form a testable hypothesis related to this statement, we would need to provide a specific and measurable variable to investigate. For example, a testable hypothesis could be: "Increasing the amount of sunlight exposure will result in faster growth rates of plants." This hypothesis can be tested by conducting an experiment where different groups of plants are exposed to varying levels of sunlight, and their growth rates are measured and compared.

In the given statement, "growing" is a general characteristic of plants and does not provide a specific variable that can be measured or manipulated. Additionally, the statement does not specify any conditions or factors that can be controlled or changed to test the hypothesis.
