Answer:
Each bite passes through several "cells" within the digestive system, and each of them has a specific function in terms of processing uneaten food.
Explanation:
The food begins to be processed in the mouth and prepared for the upcoming digestion process.
Saliva is important for food processing, among other things because it contains the enzyme ptyalin (alpha-amylase), which is responsible for the breakdown of starch and glycogen and continues its activities in the stomach.
Well-chewed food passes through the pharynx to the esophagus. During the swallowing of food, the opening of the trachea is closed, although it is possible that some crumb of food strays and causes a strong cough, which expels the excess from the trachea.
From the esophagus, food comes into the stomach, which is surrounded by ribs. Stomach acid is extremely strong and enables the conversion of food into liquid, which facilitates the further process of digestion.
Food from the stomach continues its way through the digestive tract to the duodenum, from the duodenum it reaches the small intestine.
Food processing in the large intestine is the last phase of digestion of food in the digestive tract. When the waste materials reach it, they need up to 24 hours to pass through the large intestine and reach the other end.

What happens during fertilization that makes the offspring unique compared to the original cells?
Please write the answer in one sentence!
And please, if you do not know the answer, please don´t answer.
Answer:
The union of an egg and sperm forming a zygote is known in biology as fertilization, during this process the zygote becomes a morula, meaning that the female reproductive cell divides after that union generating many other cells together into a solid ball of cells, giving rise to the embryo with the potential for development, fostered by chemical reactions among the sperm enzymes and the egg's plasma; mitosis and meiosis are included throughout the whole process.

Explanation:
explain the two inheritance patterns of blood type
Answer:
The ABO blood type is inherited in an autosomal codominant fashion.
The Rh system of blood groups determines the gene that forms two alleles: dominant (D) and recessive (d).
Explanation:
The dominant allele determines the synthesis of antigen D, so people with this antigen are referred to as Rh +. The recessive allele is dysfunctional so no D antigen is produced and individuals are Rh-
The ABO blood group system determines a gene that has three alleles:
A, B, and O allele.
Alleles A and B are functional and determine the synthesis of certain antigens (agglutinogens A B) that are found on erythrocytes.
In this exercise we have to use the knowledge of blood to explain its inheritance factors, so we want to explain how:
So we know that blood types in addition to the types known as ABO, there is also the RH factor which is the biggest inheritance.
What are the 3 blood types?Type A blood has A antigens, B blood has B antigens, AB blood has both antigens, and type O has neither. Red blood cells also have another type of antigen called RhD, which is part of a family made up of 61 Rh type antigens. When the blood has RhD, it is type positive.
Our blood group is inherited from both parents. Just as we are given physical characteristics like skin color or hair, we also inherit blood type. Surprising as it may seem, blood group is not genetically determined at birth according to the contributions of both parents.

Cellular respiration is a series of complicated reactions. Some of the enzymes that are necessary for the reactions to take place effectively are not produced by the body and must be eaten in a person's diet. Which answer correctly explains what happens when a person's diet lacks the necessary enzymes for cellular respiration?
Answer:
Lack of necessary enzymes for cellular respiration will lead to a decrease in the cell's energy level will diminish as the enzyme decreases.
Explanation:
Cellular respiration is a bunch of metabolic responses and cycles that occur in the cells of life forms to change over compound energy from oxygen atoms or supplements into adenosine triphosphate (ATP), and afterward discharge side-effects.
The responses engaged with breath are catabolic responses, which break enormous particles into more modest ones, delivering energy in light of the fact that frail high-energy bonds, specifically in sub-atomic oxygen, are supplanted by more grounded bonds in the items.
Respiration is one of the key ways a cell discharges substance energy to fuel cell movement. The general response happens in a progression of biochemical advances, some of which are redox responses. Albeit cell breath is in fact a burning response, it unmistakably doesn't take after one when it happens in a living cell in view of the moderate, controlled arrival of energy from the arrangement of responses.
Answer:
D. The cell's energy level will diminish as the enzyme decreases

Structures that form the voltage sensors of K channels Group of answer choices extend into the intracellular space. are embedded in the cell membrane. are located within the channel pore. extend into the extracellular space. are embedded in the cell membrane but extend into the extracellular space when the membrane is depolarized.
Answer:
are embedded in the cell membrane
Explanation:
Voltage-gated ion channels are transmembrane proteins activated by changes of the electrical potential across the plasma membrane. Structurally, voltage-gated Potassium (K) channels are composed of six transmembrane helices where amino- and carboxyl-terminal peptides are localized intracellularly (in the cytoplasm). The Helices 1 to 4 (H1-H4) comprise the voltage sensor domain that forms an anti-parallel helical bundle. H4 has many positively charged amino acids (Arg and Lys residues) which are key to the voltage-sensing function. Finally, Helices 5 and 6 (H5-H6) form the channel pore which is localized in the center of the protein.

im so sorry im asking so much of you guys tonight im just under a lot of pressure and need help.
Answer:
The correct answer is - a. Arginine-leucine-proline-aspargine-lysine-arginine
Explanation:
Amino acids are translated from the mRNA codons with the help of ribosomes and the mRNA that codes amino acids are encoded or transcript the DNA codons in the complementary sequence of DNA. So, to find out the amino acid from the DNA sequence given we need to encode THE DNA sequence in mRNA and then find the amino acid from the chart with the help of mRNA codons-

Why can't all the energy in one trophic level be transferred to the next?
Answer:
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. ... A food chain can usually sustain no more than six energy transfers before all the energy is used up.

Explanation:
Explain why one cell would have so many different kinds of proteins embedded in the cell membrane
Answer:
membrane proteins play different roles (for example, transport of nutrients, signaling pathways, etc)
Explanation:
Membrane proteins are key components that form and interact with biological membranes. Thus, membrane proteins can be classified as 1-integral membrane proteins which are components of the cell membrane and 2-transmembrane proteins that penetrate the membrane in one or both sides of the membrane. These proteins account for different cellular functions. Some functions of membrane proteins include:
- Cell structure (attachment to the extracellular matrix and/or the cytoskeleton)
- Transport of nutrients and waste products
- Intercellular interaction between cells.
- Signaling transduction functions
- Cell recognition (e.g., during innate immune responses)
Answer:
Each type of cell has, in its cell membrane, specific proteins that help it control the intracellular environment and that interact with specific signals from its environment.
Explanation:
Some proteins are completely integrated into the membrane and are called membrane proteins or integral transmembrane proteins since they "cover" both layers of the membrane. Transmembrane proteins are useful to the cell because they can interact with molecules outside the cell and send information about the extracellular environment into the cell. Other proteins are more loosely bound to the inside or outside of the membrane and are called peripheral membrane proteins. Peripheral membrane proteins are often used by the cell during signal transduction - the process by which one cell responds to a signal from another cell.
