Explanation:
Explain how the stomach Depends on other body systems to carry out its role in breaking down food molecules.
why does food get cold but drinks get hot
Answer:
it might be because of the room temperature.
Explanation:
since drinks are colder than the room temperature they will get warmer to be the same as the room temperature and because food is hotter than room temperature it gets colder to be the same as the room temperature. dont quote me on that just a guess

why do you need to chew the food well
Answer:
Because if that's how we get the full benefit from foods. Also, when you chew your food properly, your body releases digestive enzymes in the stomach that help to break down food so that your body can convert it into energy.

In which experimental set up shown would you expect the Elodia plant inside a test tube to produce the least amount of oxygen
Answer:
Due to less concentration of carbondioxide gas.
Explanation:
Elodia plant inside a test tube produces the least amount of oxygen due to limited carbondioxide gas that is necessary for photosynthesis process. If a test tube has less amount of carbondioxide gas which is a reactant in photosynthesis so in the end the Elodia plant generates less amount of glucose as well as oxygen while on the other hand, if there is more carbondioxide gas is available to Elodia plant, more oxygen as well as glucose is produced.

Answer:
A and B
Explanation:
explain the process of digestion abd absorption of carbohydrates.
Explanation:
the food u eat will goes from oesophagus to ur stomach and then it is mixed by hcl present in your stomach that makes the medium acidic for pesin to digest protein and then bile juice from liver makes the medium alkaline and breaks the larger globules of carbohydrates for enzymes then the food goes goes to small intestine that secretes intestinal juice that converts carbohydrates into glucose
tRNA molecules deliver amino acids to ribosomes where the amino acid next
A. forms an ionic bond with another amino acid
B. is deaminated and catabolized
С. becomes an anticodon
D. is covalently bonded to a growing polypeptide
E. forms hydrogen bonds with esters
Answer:
tRNA molecules deliver amino acids to ribosomes where the amino acid next becomes an anticodon (option C).
Explanation:
A tRNA molecule is able to deliver amino acids to the ribosomes for protein synthesis, forming an anticodon that complements the codon of the mRNA being translated. The mRNA molecules are responsible for conducting the genetic code —obtained from DNA transcription— to be translated by the ribosomes. This code is established by sequences of three nucleotides, called codons, which encode different amino acids.
What happens when mRNA molecules expose codons to ribosomes is that a tRNA molecule containing a complementary anticodon is formed, which is conducted to the ribosome to bind to the codon. This allows, according to the genetic code, the formation of a protein with a specific sequence of amino acids.
tRNA molecules deliver amino acids to ribosomes where the amino acid - С. becomes an anticodon.
During translation tRNA, molecules deliver amino acids to the ribosome and bind to this codon. It is a complementary anticodon to this codon.
Each tRNA molecule has two distinct endsone end binds to a specific amino acidthe other which binds to the corresponding mRNA codon. The first tRNA transfers its amino acid to the amino acid on the newly arrived tRNA, and a chemical bond is made between the two amino acids.Thus, tRNA molecules deliver amino acids to ribosomes where the amino acid - С. becomes an anticodon.

What are the possible benefits of hybridization?
Answer:
Advantages of hybridization include passing along favorable traits and prolonging the survival of a threatened or endangered species, but a disadvantage is that hybrid animals have more difficulty finding mates and successfully breeding. Hybridization occurs naturally and through human initiation.

Answer:
B. A helicase enzyme unwinds the DNA molecule, then corresponding nucleotides are added to the separated original strand forming two separate semiconservative molecules
Explanation:
DNA Replication is an important phenomenon as far as cell division is concerned. It is the process whereby a DNA molecule doubles its content or forms two DNA molecules from one.
In the semi-conservative model of DNA replication, an enzyme called DNA helicase unwinds the double stranded DNA molecule into two single strands. The single strands are then used as template for DNA polymerase to synthesize another molecule of DNA. Hence, two separate DNA molecules comprising of one old strand and one new strand.

Examine equations A and B below. Then answer the questions.
(A) 2H2 + O2 ® 2H2O (B) H2CO3 - H + HCO3
20. Which equation represents the formation of water?
21. Which equation represents the formation of an acid solution?

23. How many atoms of hydrogen (H) are on both sides of equation
24. How many atoms of hydrogen (H) are on both sides of equation
25. In which equation are carbonic acid molecules broken apart into
hydrogen ions and bicarbonate ions?
Answer: 20. A 21. B 22. A=2, B=3 23. A=4, B=3 25. B
Explanation: A has H2O (water). B has a hydrogen ion, so acidic.
In B H2CO3 is carbonic acid
The loss of hydrogen atoms leads to the formation of acids and the hydroxide forms bases. Equation A represents the formation of water, and equation B shows the acidic solution.
What is a chemical reaction?Chemical reactions are said to be involved in producing products from the reactants that undergo chemical changes. Water is formed by reacting the four hydrogens and one oxygen molecule as:
2H₂ + O₂ → 2H₂O
Equation B represents the formation of the acid as hydrogen ions are released along the product. The proton donation (hydrogen ion) is the characteristic property of the acids.There are 2 oxygen atoms in equation A, and 3 atoms of oxygen in equation B.There are 4 hydrogen atoms in equation A and 2 atoms of hydrogen in equation B.In equation B, carbonic acid breaks to form hydrogen ions and bicarbonate ions as:H₂CO₃ → H⁺ + HCO₃
Here, carbonic acid dissociates a proton that makes the solution acidic.
Therefore, the first equation represents the formation of water by oxygen and hydrogen atoms.

Fish are considered carbon-based organism
Answer:
Its how you see it.
Explanation:
1.Life on Earth is based on carbon, likely because each carbon atom can form bonds with up to four other atoms simultaneously. This quality makes carbon well-suited to form the long chains of molecules that serve as the basis for life as we know it, such as proteins and DNA.
2.All life on earth can be thought of as "carbon-based." Just be careful about turning this around backwards. It is true that all living things contain carbon compounds... but the opposite is not true. Just because a certain material is referred to as organic does not mean it is or ever was alive.
