A: Absorption of nutrients by villi in the small intestines
B: Chewing and swallowing food
C:Recycling of water from dissolved food back into the body
D: Reaction of saliva, stomach acid, bile, and pancreatic juices with food
The example that includes only chemical changes that occur in the digestive process is the reaction of saliva, stomach acid, bile, and pancreatic juices with food. Option D.
What are chemical changes?Chemical changes refer to changes to the chemical properties of substances. In biological reactions, these substances are referred to as reactants.
Chemical changes are different from physical changes. In physical changes, only the physical properties of substances are altered while their chemical properties remain intact.
When a substance changes chemically, its physical properties most often change along. However, this is not in all cases.
Thus, looking at the examples given, their classification into either physical or chemical changes is as follows:
Absorption of nutrients by villi in the small intestines: physical changeChewing and swallowing food: physical changeRecycling of water from dissolved food back into the body: physical changeThe reaction of saliva, stomach acid, bile, and pancreatic juices with food.When saliva, stomach acid, bile, and pancreatic juices react with food, the chemical properties of food change because the enzymes convert different components of food from one form to another as part of the process of digestion.

A geneticist is studying two traits in the fruit fly - eye color and wing shape. They perform a dihybrid cross. If the genes for these traits are not linked, what proportion of the F2 offspring will be expected to display the dominant phenotype for eye color and recessive phenotype for wing shape
Answer:
3/16
Explanation:
According to Mendel's law of independent assortment of genes, when a dihybrid cross involves two genes that assort independently and one of the parents is dominant for the two genes and the other is recessive, the phenotypic ratio of the offspring at F2 would be 9:3:3:1. The proportion of the offspring with the dominant parental traits would be 9/16, those with the recessive parental traits would be 1/16, while those with mixed traits would be 3/16 each.
Assuming the eye color is represented by E and the wing shape is represented by W. At F2
EeWw x EeWw
E_W_ - 9/16 (dominant for both eye color and wing shape)
E_ww - 3/16 (dominant for eye color and recessive for wing shape)
eeW_ - 3/16 (recessive for eye color and dominant for wing shape)
eeww - 1/16 (recessive for both eye color and wing shape)
Hence, the proportion of the offspring with dominant phenotype for eye color and recessive phenotype for wing shape would be 3/16.

are phenols and glycosides induced or pre-existing defenses mechanisms for plants immunity ?
Phenols and glycosides are pre-existing defense mechanisms in plants' immune systems. These compounds are part of the plant's chemical defense arsenal and are present in various tissues even before any attack or infection occurs.
Phenols are secondary metabolites found in plants that have antimicrobial and antioxidant properties. They contribute to the plant's defense against pathogens by inhibiting the growth and development of microorganisms. Phenols also play a role in wound healing and lignification, which strengthen the plant's cell walls.
Glycosides are another class of secondary metabolites found in plants that have diverse functions, including defense against herbivores and pathogens. Some glycosides act as toxic compounds when ingested by herbivores, while others can inhibit the growth of microorganisms or interfere with their feeding behavior.
Both phenols and glycosides are produced by plants as part of their constitutive defenses, meaning they are present at baseline levels even in the absence of stress or attack. However, their production can be further induced or enhanced in response to specific stimuli, such as pathogen invasion or herbivore feeding.

if tyler does not eat a diet that includes essential acids , his cells will not be able to build what?
If Tyler does not eat a diet that includes essential amino acids, his cells will not be able to build proteins.
Amino acids are the basic building blocks of proteins. There are 20 different types of amino acids, 9 of which are considered essential because they cannot be synthesized by the body and must be obtained from food.
The 9 essential amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. These amino acids are necessary for the body to synthesize proteins, which are essential for the growth and repair of tissues, the formation of enzymes and hormones, and the maintenance of healthy bones, muscles, and skin. Without sufficient amounts of essential amino acids in the diet, the body is unable to build proteins and can lead to protein deficiency, which can cause symptoms such as fatigue, muscle wasting, and impaired immune function.
Therefore, it is important to eat a diet that includes sources of all 9 essential amino acids to ensure adequate protein synthesis and overall health.

They are termed dominant and Recessive, for the dominant allele typically masks the expression of the other allele when they are both located in the same cell.
Every gene in a species that reproduces sexually, including humans and other animals, has two copies. The two copies, which are referred to as alleles, may differ slightly from one another. The differences can alter protein expression or produce variations in the produced protein: when, where, and in what quantities protein is produced. Proteins influence traits, so varieties in protein movement or articulation can deliver various phenotypes.
The relationship between two gene versions is referred to as dominant. Each parent gives an individual two copies of each gene or allele. One allele will be expressed if a gene has different alleles; It is the most common gene. Masked is the effect of the other allele, which is called recessive.

By implementing biofuels and biodiesels, the town planner thinks that the public transportation emissions will be decreased 10 percent, from 3.15 metric tons to 2.84 metric tons! This, along with pledges from the community to decrease use of private transportation, will decrease emissions from 13.65 metric tons to 10.92 metric tons of CO2!
6. How many metric tons of emissions will be reduced per household if both of these plans succeed?
If both plans succeed, the reduction in emissions per household would be approximately 0.031 metric tons.
To calculate the reduction in emissions per household, we need to know the number of households in the town. Let's assume there are 1,000 households in the town.The reduction in emissions from public transportation is 3.15 metric tons - 2.84 metric tons = 0.31 metric tons. This reduction is spread across the entire community.Similarly, the reduction in emissions from decreased use of private transportation is 13.65 metric tons - 10.92 metric tons = 2.73 metric tons.To find the emissions reduction per household, we divide the total reduction by the number of households: (0.31 metric tons + 2.73 metric tons) / 1,000 households = 0.031 metric tons per household.Therefore, if both plans succeed, there will be a reduction of approximately 0.031 metric tons of emissions per household.
