Sigfried is a science student who develops the following hypothesis: If ants select blue sugar over red sugar, then ants prefer the color blue because it is more soothing than red. What is wrong with Sigfried’s hypothesis

Answers

It is not an issue of color, but rather of sugar content that causes the ants to choose the blue sugar over the red sugar. Because the blue sugar contains more sugar than the redsugar, the ants preferred it.

What is sugar?

All sweet carbohydrates can be referred to as sugar, however the phrase is most frequently used to refer to table sugar, also known as sucrose, or a “double sugar.” Carbohydrates are converted by the body into easily absorbed simple sugars like glucose. There are numerous varieties of sugar.

The body uses sugars and starches from carbs to feed the brain with glucose and give the rest of the body's cells energy.

Most plants have sugars in their tissues. Honey and fruit are plentiful natural sources of simple sugars.

Sugarcane and sugar beet are particularly high in sucrose concentration, making them perfect for effective commercial extraction to produce refined sugar.

Therefore, blue sugar contains more sugar than the red sugar

Explanation:

The ants choosing the blue sugar over the red sugar isn't a matter of color, but it'd a matter of sugar content.

The ants chose the blue sugar because it has more sugar content than the red sugar.

Hope it helps.

Why is it impossible for humans to digest food that contains cellulose?

Answers

Answer:

      The right answer to this question is: we don't have a specific enzyme called Cellulase.

Explanation:

        An enzyme is basically a system known as lock and key mechanism. It works like this: every single enzyme has its own form, and there's only one way of getting into it for the digestion to happen, the substrate needs to complete this system, as a key on a lock, and once this happens, the digestion can start. But humans don't have this enzyme, if they don't have it, the digestion won't happen in this case. Well known animals that have it are the ruminants, they can digest cellulose easily because they have the specific enzyme called cellulase.

Answer:

it impossible for humans to digest the food that contains cellulose because they do have an enzyme which is required to break beta acetal linkage.

Explanation:

cellulose is a polysaccharide and it is synthesized by animals, plants and in plant cell wall major component is cellulose.

it impossible for humans to digest the food that contains cellulose because they do have an enzyme which is required to break beta acetal linkage.

Ruminants such as cows in the rumen symbiotic anaerobic bacteria are present, cellulases enzyme is produced by these bacteria, that help to digest the cellulose.

In polygenic inheritance, each of the genes controlling a trait will have exactly the same influence over the trait. Group of answer choices Yes since all genes having to do with a trait always have the exact same influence on a trait. No since different genes will exert varying degrees of influence on the trait None of the other responses are satisfactory answers. No since all traits are only controlled by one gene with two alleles.

Answers

Answer:

No, since different genes will exert varying degrees of influence on the trait

Explanation:

The term quantitative heritability refers to the transmission of a phenotypic trait in which expression depends on the additive effect of a series of genes.

Polygenic heritability occurs when a trait results from the interaction of more than one gene. And these genes can also have more than two alleles. The action of many genes and alleles can cause many different combinations that are the reason for genotypic graduation.

Quantitative traits are those that can be measure, such as longitude, weight, eggs laid per female, among others. These characters do not group individuals by any precise and clear categories. Instead, they group individuals in many different categories that depend on how the genes were intercrossed and distributed during meiosis. The result depends on the magnitude in which each allele contributes to the final phenotypeand genotype. When they interact, they create a gradation in phenotypes, according to the level of contribution.  

Let us see, for instance, the eye color trait, which results from the interaction of many genes. Two of them significantly contribute to the color green, blue, or brown, while the rest of the involved genes play a role in defining the spectrum of phenotypes of each eye color. So, there are different tones of blue eyes, green eyes, and brown eyes, and the differences are determined by the contribution of each allele to the phenotype.

Final answer:

In polygenic inheritance, multiple genes influence a trait, and theycan have varying degrees of influence rather than having the exact same effect.

Explanation:

In polygenic inheritance, it is not accurate to say that all genes controlling a trait will have exactly the same influence over the trait. Polygenic inheritance involves multiple genes that work together to influence a trait. This means that these genes do not necessarily exert the same degree of influence; rather, they can and often do exert varying degrees of influence on the expression of a trait. For example, in human skin color, a characteristic feature of polygenic inheritance, several genes, each with different levels of influence, contribute to the trait's expression.

The LLQ is located___ to the LUQ.

anterior
posterior
Superior
Distal
Inferior

Answers

The anatomical terms are used to define the anatomical positions. The LLQ (Left lower quadrant) is located inferior to the LUQ (left upper quadrant). Thus, option e is correct.

What are anatomical terms?

Anatomical terms are used to define the exact position and location of the organs and the structures of the body in reference to each other. They are the directional terms that provide the details of the direction an organ is situated at.

The directional anatomical terms include superior, inferior, posterior, anterior, distal, proximal, caudal, occipital, peripheral, central, etc. The LLQ (Left lower quadrant) is the abdominal section that is located below the LUQ (left upper quadrant).

The anatomical term inferior is used to show the structure that lies below the reference organ. On the other hand, the superior shows above, the posterior shows behind, the anterior shows the front area, and the distal shows structures located further away from the origin.

Therefore, option e. the left lower quadrant is inferior to the left upper quadrant.

Final answer:

In terms of human anatomy, the Left Lower Quadrant (LLQ) is considered to be inferior to the Left Upper Quadrant (LUQ). This refers to the LLQ's position being lower or below the LUQ.

Explanation:

In anatomical terminology, the Left Lower Quadrant (LLQ) is inferior to the Left Upper Quadrant (LUQ). The human abdomen is divided into four quadrants by two imaginary lines crossing each other at the naval: one vertical and one horizontal. The LUQ is the area on the left side above this intersection, whereas the LLQ is the area below. So in the context of positions and directional terms in human anatomy, 'inferior' means 'below' or 'lower than'.

Please select the word from the list that best fits the definitionwhere the energy in food is stored until it is released

Answers

Answer:

The correct answer is - Mitochondria.

Explanation:

Mitochondria is the location that stores the energy in food until it is released. It is the cellular organelle that is the place where the cellular respiration process takes place.

In this organelle, the stored food is converted into a usable energy form, ATP. Mitochondria is also known as the powerhouse of the cell as it converts and releases the energy from the stored sugar or food.

Thus, the correct answer is - mitochondria.
