Answer:
Mouth -Esophagus-- Stomach -Duodenum -Jejunum -Brush border disaccharidases--Glucose transporters--Active transport--Blood-Glycolysis-Pyruvate--Citric acid cycle - Carbon dioxide and water : )
Explanation:
The journey of a glucose molecule from the mouth and ultimately to the muscle cells for energy in the correct order is:
Mouth > Esophagus > Stomach > Duodenum > Jejunum > Brush Border Disaccharidases > Blood > Glucose Transporters > Glycolysis > Pyruvate > Citric Acid Cycle > CO2 and Water > Active Transport > Electron Transport System.
The drink rich with disaccharides starts its journey from the mouth cavity and moves through the esophagus to the stomach. The disaccharide digestion takes place when it reaches the jejunum through the duodenum of the small intestine by enzyme maltase that also presents in Brush Border Disaccharidases to glucose.
Glucose moves o blood and through a glucose transporter for cellular respiration that starts with glycolysis that converts glucose to pyruvate and enters in TCA cycle and releases CO2 and water as byproducts that ultimately moves to the ETS system to provide energy to the muscles.
Thus, the correct answer is - given above in the correct order.

What trend, if any, is evident in Mel’s data?
The trend that is evident is: Initially, there seems to be support for Mel's hypothesis, but the gold data is not consistent with the predicted trend.
Option C is correct.
How do we calculate?The data for zinc, nickel, copper, and silver shows that as the density increases, the melting point tends to increase.
From the data we can see , the data for gold does not follow this trend, as its density is lower than silver but its melting point is higher.
Therefore, while there is some initial support for Mel's hypothesis, the inconsistency with gold indicates that the relationship between density and melting point is not solely determined by density.

Individual amoebae of the slime mold Dictyostelium discoideum aggregate to form a spore-producing fruiting body. Cheaters make spores, but do not contribute to the stalk. Since many more spores with cheating genotypes are dispersed, they have higher fitness. Why does directional selection not lead to fixation of the cheater genotype
Answer:
It is an example of frequency-dependent selection. Due to several cheaters in the population, the fruiting body's stalk is not made properly. So, all individuals have lesser fitness.
Explanation:
Natural selection:
The population contains both superior as well as an inferior organism where natural resources are limiting so it will cause competition between organisms. As a result of competition, it will select superiors, and inferiors are deleted and they are given reproductive advantages. Due to this reproductive advantage new population emerges. It is more suitable for the environment.
Natural selection divides into three parts that are directional, disruptive, and stabilizing selection.
The given question is the example of frequency-dependent selection. Due to several cheaters in the population, the fruiting body's stalk is not made properly. So, all individuals have lesser fitness. Directional selection will not lead to fixation of cheater genotype. This is because cheating can be controlled through high relatedness in social groups, resulting from kin discrimination.
It is controlled through positive pleiotropy, where the cooperation gene has an additional vital function. Cheating will be controlled if stalk vs. spore is a result of environmental, not genetic factors. An example, spore fate can be a result of the position in the mitotic cell cycle.

What is Cellular respiration? Draw out the equation. How does it compare to Photosynthesis?
Cellular respiration is the breakdown of glucose and other molecules by cells to generate energy in the form of ATP. (adenosine triphosphate).
There are three steps to the process: glycolysis, the Krebs cycle, and oxidative phosphorylation.
Cellular respiration has the following molecular equation:
\(C_6H_{12}O_6 + 6O_2 - > 6CO_2 + 6H_2O + ATP\)
This equation represents the breakdown of glucose and oxygen to produce carbon dioxide, water, and ATP.
In contrast, photosynthesis is the process by which plants, algae, and some bacteria transform solar light energy into chemical energy in the form of glucose and other organic compounds.
The process is divided into two stages: light-dependent reactions and light-independent reactions. (also known as the Calvin cycle).
Although cellular metabolism and photosynthesis are diametrically opposed processes, they are also mutually beneficial. The reactants of one process are the results of the other.
For example, the oxygen created during photosynthesis is used by cells to produce ATP during cellular respiration, and the carbon dioxide produced during cellular respiration is used by plants to produce glucose during photosynthesis.

What is the difference between blue green and fungi?
Blue-green algae are photosynthetic prokaryotes, while fungi are eukaryotes that obtain nutrition through absorption.
Blue-green algae and fungi are both organisms, but they belong to different domains and have distinct characteristics. Blue-green algae, also known as cyanobacteria, are classified under the domain Bacteria, while fungi belong to the domain Eukarya.
Blue-green algae are prokaryotic organisms, lacking a true nucleus and membrane-bound organelles. They obtain energy through photosynthesis and are capable of converting sunlight into chemical energy. They typically inhabit aquatic environments, such as lakes, ponds, and oceans, and some species can fix atmospheric nitrogen.
On the other hand, fungi are eukaryotic organisms with a distinct nucleus and membrane-bound organelles. They obtain nutrition by absorbing organic matter from their surroundings. Fungi play crucial roles in decomposition and nutrient cycling in ecosystems. They can be found in various habitats, including soil, plants, and even as symbiotic partners with other organisms, such as in mycorrhizal associations.
In summary, the primary differences between blue-green algae and fungi lie in their cellular structure, mode of nutrition, and classification. While blue-green algae are photosynthetic prokaryotes, fungi are eukaryotes that obtain nutrition through absorption. Understanding these distinctions helps in appreciating the diversity and ecological significance of these two groups of organisms.

is hair a living thing explain why or why not
Answer:
Hair and nails are not living things they are considered living because they are attached to a living thing but no they are not living.
Explanation:
Hope this helped
Hair is not considered a living thing. Hair is composed of dead cells that are produced by living cells in hair follicles.
Is hair a living thing?Hair is primarily made up of a protein called keratin, which is produced by specialized cells within the hair follicles. These cells, called keratinocytes, undergo a process of differentiation as they move upward through the hair follicle, eventually becoming fully keratinized and forming the hair shaft. Once the hair shaft is fully formed, it no longer possesses any metabolic or cellular activities. It lacks a blood supply, nerve endings, and other cellular structures that are characteristic of living tissues.
While hair itself is not alive, the hair follicles that produce hair are living structures and play a crucial role in hair growth and maintenance. Hair growth occurs in cycles, with each hair follicle going through a growth phase (anagen), a transitional phase (catagen), and a resting phase (telogen). During the anagen phase, the hair follicles actively produce new hair cells, which eventually become part of the hair shafts.

Scenario 1: 50% chance to have 5 fingers and 50% chance to have 4 fingers. Scenario 2: 75% chance of having a baby with 5 fingers and 25% chance of having a baby with 4 fingers.
In the first case, the offspring has a 50% chance of inheriting the dominant T allele from the 5-fingered father and a 50% chance of inheriting the recessive T allele from the 4-fingered mother. Therefore, the probability of having a child with 5 fingers is 50%. The probability of having a 4-toed child is also 50% since the offspring will only have 4 fingers if they inherit two copies of the recessive allele t.
In the second case, both parents have 5 fingers and are heterozygous (Tt), so there is a 75% chance that the offspring will inherit at least one T dominant allele and have 5 fingers. There is a 25% chance of inheriting two copies of the recessive allele t and having 4 fingers. Therefore, the probability of having a child with 5 fingers is 75% and the probability of having a child with 4 fingers is 25%.
