Answer:
Mechanical digestion can only break up the food particles into smaller pieces. A chemical digestion process called enzymatic hydrolysis can break the bonds holding the molecular 'building blocks' within the food together. For example, proteins are broken down into their 'building block' amino acids.
Explanation:
Fats, proteins, and carbohydrates are macromolecules that are broken down into smaller molecules during digestion.
What is digestion?The term "digestion" describes the process by which food is broken down into smaller pieces that can be absorbed into the bloodstream.
The breakdown of food into smaller bits, known as mechanical digestion, takes place in the mouth. Chemical digestion, on the other hand, takes place in the gastrointestinal tract when the meal is broken down into small molecules by digestive enzymes. Digestion begins from the buccal cavity.
Macromolecules such as fats, carbohydrates, and proteins, are broken down into their monomeric form. Thus, this four are the large molecules broken down into smaller molecules during digestion.

Bromothymol blue (BTB) is a chemical indicator for carbon dioxide (CO2). In the presence of carbon dioxide (CO2), BTB turns from blue to yellow. An aquatic plant was placed into two test tubes containing BTB, and the test tubes were closed with a stopper. Then, one test tube was placed in the dark, and the other test tube was placed in direct sunlight. The test tube in sunlight stayed blue indicating no CO2 was present, while the test tube in the dark changed to yellow. Which statement best explains why the solution in the test tube placed in the dark changed to yellow?
Answer:
Explanation:
Although no options was given, the explanation below should give detail explanation.
The Chemical reactants( internal factors) for the process of photosynthesis are C02 and H20, and enzymes. Other external factors are sunlight and chlorophyll.Therefore for a plant to undergo photosynthesis these reactants must be present in the presence of sunlight.
In the present scenario the plant in the test tube exposed to sunlight must used up the C02 with water and exposed sunlight to produce O2 -the by products and CHO,Protein and Lipids in plants.
Since the C02 has metabolised,no CO2 would be present in the test tube of the plant and the water, hence BTB is negative,blue- no C02.
However,the plants in the dark lacks the supply of sunlight therefore no photosynthesis could occur.Consequentially the C02 is not metabolized,and its concentration is high in the leaf in the test tube placed in the dark.This is indicated as yellow positive by the BTB which change from Blue to yellow.

Verbal irony
ok so...
1. The reader knows that the boy is about to break up with his girlfriend, but the girlfriend doesn't know. That is dramatic irony
because Dramatic Irony appears when the readers know something the character does not know. For example, in scary stories, the reader often knows where the bad guy hides, but the character does not. As the character approaches the hiding spot, the readers may experience heightened suspense due to the dramatic irony.
2.Dave's blood pressure medicine game him a heart attack. That is
Situational irony.
Situational Irony happens when something happens that the reader does not expect to happen. For example, if someone robs a thief in a story, that portrays situational irony. Readers would not expect a thief who robs others to be the one who gets robbed.
3. "Oh, great! I'm so glad it's raining, and I forgot my umbrella." That is Verbal irony
Verbal Irony occurs when a character says one thing but means something else. This type of irony is also known as sarcasm. For example, a parent might reveal verbal irony, or sarcasm, by showing up at the door of an extremely messy room and commenting, "I've never seen your room this clean before! You are grounded." Clearly, the parent revealed sarcasm when commenting about the cleanliness of the room.

Cells are the building blocks of life, yet atoms and molecules are smaller than cells. Why are cells, not atoms, the basic building blocks of life?
The basic unit of life has to be a living thing, atoms aren't alive yet they make up cells, which are alive. However, atoms are building blocks of everything. Yet cells themselves are living, therefore are the building blocks of all forms of life.
Atoms are smaller than cells. Yet cells are the building blocks of life because atoms are not living, and living organisms are made up of cells because cells are living components.
What are cells and atoms?Cells are the basic components of living organisms. Atoms are the basic and smallest unit of matter that is nonliving.
Since atoms do not have life, they cannot be the fundamental building block of life; nonetheless, they do makeup living cells.
Atoms are the fundamental units of matter, nevertheless. However, because cells are living entities in and of themselves, they serve as the foundation for all life.
Thus, cells are larger than atoms. However, as atoms are not alive, cells are the fundamental unit of life, and since cells are living entities, they are the foundation of all living things.

If it really helped please give me brainliest
A nonsense mutation is one mutation in the CFTR gene that leads to cystic fibrosis causes translation to end earlier in the gene sequence.
Cystic fibrosis is a genetic disorder that is caused by different mutations within the CFTR gene.
The CFTR gene codes for the CFTR protein whose function is as an anion channel (chloride ion) which helps control the movement of water in and out of the membrane of cells that are specialized to produce mucus, sweat, saliva, tears and digestive enzymes
When CFTR protein is defective or absent, thick, sticky mucus accumulates in these cells, obstructing the airways and glands.
The most common mutation of the CFTR gene is a deletion whereby the codon for the amino avid phenylalanine is deleted resulting in the production of a defective CFTR protein.
Another form of mutation in the CFTR gene is a nonsense mutation in which a stop codon is inserted in the middle of the gene resulting in the production of a shortened CFTR protein, which is then degraded by the cell.
Therefore, a nonsense mutation in the CFTR gene leads to cystic fibrosis by causing translation to end earlier in the gene sequence.

Explain why diversity is important for the survival of a species?
Answer:
The importance of genetic diversity. More specifically, genetic diversity can be a species natural defence system against disease and survival even under extreme weather conditions but more importantly, genetic diversity can help weed out unfavourable traits in species which maximises opportunities for thriving in any environment². hoped it helped.
Explanation:
Increased genetic diversity leads to increased chance of species survival. Species with a limited variety of phenotypes and where all members of the species are similar to one another have a smaller chance of coping with environmental variability compared to a species with greater diversity.

Budding. Organisms reproduce by splitting off new individuals from existing ones, resulting in genetically identical parent and daughter organisms.
What do you mean budding?Budding is an asexual mode of organism formation. A new organism is formed from a small part of the parent's body during this process. A newly formed bud separates to form a new organism. The newly formed organism remains attached as it grows.To create an advantageous variety (cultivar) and rootstock combination, a single bud from a desirable plant is inserted into an opening in the bark of a compatible rootstock.Budding, also known as bud grafting, is a type of vegetative or clonal plant propagation that produces an exact replica of the parent plant. Chip budding and T budding are two slightly different methods of budding.To learn more about : Budding

what is different between leaching and erosion
Erosion is the natural process by which soil / rock are removed from the Earth's surface by exogenetic processes whereas Leaching is the removal of soluble material from soil or other material by percolating water.
What do you mean by soil erosion?Soil erosion is the denudation or wearing away of the upper layer of soil. It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice, snow, air, plants, and animals.
Soil erosion occurs primarily when dirt is left exposed to strong winds, hard rains, and flowing water. In some cases, human activities, especially farming and land clearing, leave soil vulnerable to erosion.
Removing trees and plants, plowing fields, and overgrazing by livestock disrupts roots that stabilize sediment and soil. These human activities can increase erosion rates 10 to 100 times that of non-human geologic processes.
