20. Which macromolecule is structure A composed of and what is its function?
A.) Carbohydrates - makes quick energy
B.) Lipid - makos fats
C.) Nucleic acid - makes genetic material
D.) Protein- facilitates diffusion
The structure A is a PROTEIN, it is composed of amino acids and its function is to facilitate diffusion (option D).
Channels and/or carriers are specific membrane proteins that enable the movement of molecules across biological membranes.In facilitated diffusion, specific carriers enable the passage of molecules across biological membranes in favor of a concentration gradient, ie., from a region of high concentration to a region of low concentration.For example, aquaporins are membrane proteins (carriers) used by cells to allow the passage of water molecules across biological membranes.In conclusion, structure A is a PROTEIN, it is composed of amino acids and its function is to facilitate diffusion (option D).

Which of the following items are the main outputs, our products, of cellular
respiration? Select all correct
answers.
water
energy
oxygen
carbon dioxide
Answer:
water and carbon dioxide are by-products. ATP is the energy transformed from the process
Water and carbon dioxide items are the main outputs, our products, of cellular respiration.
What is Cellular respiration?A sequence of chemical processes known as cellular respiration convert glucose into ATP, which can then be used as energy for a variety of bodily functions.
Glycolysis, the citric acid cycle, and oxidative phosphorylation are the three basic processes that take place during cellular respiration. The citric acid cycle happens in the mitochondrial matrix, oxidative phosphorylation happens on the inner mitochondrial membrane, and glycolysis happens in the cytoplasm.
Glucose, ATP, and NAD+ are the initial reactants and ATP and H2O are the end products of cellular respiration. The enzymes phosphofructokinase-1, pyruvate dehydrogenase, and isocitrate dehydrogenase control the rate of cellular respiration.
Therefore, Water and carbon dioxide items are the main outputs, our products, of cellular respiration.

Tay-sachs disease is an inherited genetic disorder in which cellular wastes are not properly cleared out from the cell. In turn, these wastes then accumulate to a toxic level within the cell, ultimately causing cell death.
Which labeled structure would be the most likely location in which Tay-sachs disease occurs?
Choose 1 answer:
Answer: C
Explanation: Since individuals with Tay-sachs cannot properly clear out cell wastes, the most likely location in which their cells would be affected is the lysosome, labeled as C. Hope this helps. Have a nice day :)
The most likely location in which Tay-sachs disease occurs would be in the lysosomes.
What is Tay-sachs disease?Tay-Sachs disease is a rare inherited genetic disorder that affects the nervous system. It is caused by a deficiency of an enzyme called hexosaminidase A, which is responsible for breaking down a specific type of lipid called ganglioside GM2. Without this enzyme, the ganglioside GM2 accumulates in the lysosomes, leading to the toxic accumulation of cellular waste and cell death. The accumulation of these waste products causes severe damage to the nervous system, particularly the brain, leading to a loss of intellectual and physical abilities.
Symptoms of Tay-Sachs disease typically appear in early infancy and include a loss of motor skills, blindness, deafness, and an inability to swallow or speak. In most cases, affected infants do not survive beyond the age of 4. There is currently no cure for Tay-Sachs disease, but early diagnosis and management of symptoms can help improve the quality of life for affected individuals.

The model shows a mutation to a partial sequence of bases in a gene. Which type of mutation does the model demonstrate? *
Answer: Insertion
Explanation: I just took a quiz.
The given model is representing insertion mutation. The correct option is B.
What is insertion?A mutation is an alteration in an organism's DNA sequence. Mutations can occur as a result of mistakes in DNA replication all through cell division, mutagen exposure, or viral infection.
In genomics, an insertion is a type of mutation that incorporates the addition of one or maybe more nucleotides to a segment of DNA.
An insertion can entail the inclusion of any amount of nucleotides, ranging from one to an a whole chromosome.
An insertion, also known as an insertion mutation in genetics, is the addition of one or even more nucleotide base pairs to a DNA sequence. This is common in microsatellite areas due to DNA polymerase slippage.
In all events, single nucleotide insertions and deletions are the most common.
Thus, the correct option is B.

Which does not occur during translation? tRNA pairs with complementary mRNA. Met-tRNA binds to the start codon. DNA is transcribed into a complementary strand of mRNA. A chain of amino acids, linked by peptide bonds, is formed.
Answer:
DNA is transcribed into a complementary strand of mRNA.
Explanation:
Translation is the second process of gene expression, which involves the synthesis of proteins from mRNA transcript. Before this translation process occurs, a gene must have undergone a process called TRANSCRIPTION to yield a single stranded mRNA.
The translation, which occurs in the ribosome, then occurs where Met-tRNA initially binds to the start codon, tRNA (transfer RNA) pairs with complementary mRNA, and a chain of amino acids, linked by peptide bonds, is formed. However, the transcription of DNA into a complementary strand of mRNA does not occur during TRANSLATION.
Answer:
It is C!!Explanation:
DNA is transcribed into a complementary strand of mRNA.
