Give TWO reasons why mechanical digestion of food is important! Marking brainliest
Answer:
Mechanical digestion is a purely physical process that does not change the chemical nature of the food. Instead, it makes the food smaller to increase both surface area and mobility. It includes mastication, or chewing, as well as tongue movements that help break food into smaller bits and mix food with saliva.Explanation:

What is the
Digestive process
Answer:
the digestive process is the process in which food travels down our thorax into our stomach where the acid breaks it down to gather nutrients and what not to fuel our body then the rest is turned into waste.
Explanation:
As organisms release energy during cellular respiration, carbon dioxide is produced from the carbon in energy storage molecules. This process moves carbon from biotic to ________________ a the producers b the decomposers c abiotic matter

Explain how a wholemeal sandwich with tuna and tomatoes will be broken down by the digestive system. Start the process from the mouth and end at the anus.
Answer:
All of our energy and nutrition come by way of the gastrointestinal (GI) tract. It is an amazing machine well designed for digesting and absorbing nutrients and for shielding the rest of the body from microorganisms, viruses and other foreign matter. The GI tract spans from the mouth to the anus, with each separate organ having a role in digestion, absorption or excretion.Lastly, if you would like to learn more about yourself and how you can best reach your own nutritional and fitness goals, we encourage you to take a look at the following home health testing guides and resources:

Scientists find cell with a genetic mutation in the cyclin dependant kinase gene. The mutation leads to a misshapen CDK molecule that will not bind to cyclin molecules. How would this impact the cell cycle of that cell
Answer:
The mutation leads to a misshapen CDK molecule that will not bind to cyclin molecules. How will this impact the resulting daughter cell? Explain. If cyclin molecules did not bind to CDK, the cell could not progress through the cell cycle.

When dissolved carbon dioxide (CO2) combines with ocean water it forms a(n)
Answer:
Carbon dioxide (CO2) dissolves in the ocean and reacts with water to form carbonic acid—which in turn generates bicarbonate, carbonate, and hydrogen ions. Calcium and carbonate ions combine to form the solid calcium carbonate crystals in their shells and skeletons.
Explanation:
As the troponin changes shape (due to binding calcium), it moves the ______ molecule to which it is attached, thus exposing the active sites on the G-actin molecules.
As the troponin changes shape (due to binding calcium), it moves the tropomysin molecule to which it is attached.
Once calcium binds to troponin and causes it to change it shape, it removes the tropomysin away from the binding site therefore effectively exposing the myosin binding sites.
This occurs during muscle contraction (movement) in the skeletal muscles.

All of the following among A-D apply to toll-like receptors EXCEPT A. they bind to PAMPS B. they induce the release of cytokines when activated C. they directly lyse bound pathogens D. when stimulated, they activate the immune system of the body E. there are no exceptions, A-D are all true
The toll-like receptors do NOT directly lyse bound pathogens (Option C). These protein receptors play fundamental roles in the innate immune system.
Toll-like receptors (TLRs) are single-pass membrane-spanning protein receptors that play fundamental functions in the innate immune system.
TLRs are differentially expressed on the surface of antigen-presenting cells (i.e., macrophages and dendritic cells) in order to recognize evolutionary conserved antigenic domains in different pathogenic microorganisms (e.g. bacteria).
TLRs initiate innate immune responses such as, for example, inflammatory responses, by identifying conserved pathogen-associated molecule patterns (PAMPs).

Which biome are the best suited for agriculture? Explain why each of the biomes you did not specify is less suitable for agriculture.
List reasons you would or would not be concerned about eating genetically modified food
Answer:
Reasons I would be concerned about eating GMO foods:
Explanation:
The FDA declaring them to be "substantially equivalent" to non-GMO foods amid controversy that adequate scientific testing had not been done.
Michael Taylor being in the FDA when "substantial equivalence" was declared. Michael Taylor was a Monsanto employee before taking the position at the FDA.
The technology itself of taking a gene from one species and inserting it into another species (horizontal breeding). While that may be perfectly harmless it is new technology that many believe has not been proven to be safe.
Greater amounts of pesticides being used on GMO crops, which means more pesticides may be getting in our foods.
Crops that are engineered to produce an insecticide in the plant itself possibly having harmful health effects on us. There is some evidence that this may be happening.

a difference between bacterial and eukaryotic transcription
Answer:
According to Wikipedia, In bacteria, transcription and translation can occur simultaneously in the cytoplasm of the cell, whereas in eukaryotes transcription occurs in the nucleus and translation occurs in the cytoplasm.
GIVE BRAINLIEST PLZ! :)
The difference between bacterial and eukaryotic transcription is that in bacteria, transcription and translation can occur simultaneously in the cytoplasm of the cell, whereas in eukaryotes transcription occurs in the nucleus and translation occurs in the cytoplasm.
What is the difference between eukaryotes and prokaryotes?The main difference between eukaryotes and prokaryotes is that the eukaryotes are well developed and advanced and have different cell organelles and they have different functions in the cell and the prokaryotes are not well developed and they are found in the unicellular organisms.
The unicellular organisms are made of one cell and carry out the processes of life as a single cell and the multicellular organisms are made up of two or more cells that have specific functions to contribute to the life processes.
Therefore, The difference between bacterial and eukaryotic transcription is that in bacteria, transcription and translation can occur simultaneously in the cytoplasm of the cell, whereas in eukaryotes transcription occurs in the nucleus and translation occurs in the cytoplasm.

organism that makes its own food
Answer:
Explanation:
autotrophs
An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers. Plants are the most familiar type of autotroph, but there are many different kinds of autotrophic organisms.

Name three components of the cell membrane and explain how each contributes the semipermeable nature of the membrane.
The principal components of the plasma membrane are lipids ( phospholipids and cholesterol), proteins, and carbohydrates. The plasma membrane protects intracellular components from the extracellular environment. The plasma membrane mediates cellular processes by regulating the materials that enter and exit the cell.
The effect of pH on a certain enzyme is shown in the graph. At what pH would the enzyme be most effective?
Answer:
2
Explanation:
The enzyme will be the most effective between 8 and 10
The enzyme will show maximum activity in the range of pH between 8 and 10. This can be the enzyme's optimum pH as at this range it is found to be most effective. Thus, the correct option is 2.
What are enzymes?Enzymes are the biocatalysts. They act as enzymes in the biochemical reactions by reducing the activation energy required by the reactants to form products. Enzymes remain unused in a reaction.
Enzyme activity depends upon different factors which include temperature, pressure, pH, etc. Enzymes show maximum activity at the optimum conditions of these environmental factors.
From the given graph, it can be interpreted that the enzyme shows maximum rate of action between the pH range of 8 and 10. Thus, this is the optimum range of pH.
Therefore, the correct option is 2.
