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.

1. When studying animal behavior, the distribution of organisms within a choice
chamber can be studied to identify animal preferences. 20 Isopods are
placed in a 2-choice choice chamber. A cotton ball dampened with distilled
water is placed in Chamber A; A dry cotton ball is placed in Chamber B.
After 15 minutes 2 Isopods are located in Chamber B, and 18 isopods are found
in Chamber A. Perform the chi-squared test to determine if the distribution
of isopods is significant or due to random chance. (3 points)
Answer:
The distribution of isopods is statistically significant.
Explanation:
H₀= Individuals will be equally distributed
H₁ = Individuals will not be equally distributed.
Chi square= ∑ ((O-E)²/E)∑ is the sum of the terms
O are the Observed individuals: 2 in chamber B, and 18 in chamber A.
E are the Expected individuals: 10 in each chamber
X² = ∑ ((O-E)²/E) = ((2 - 10)²/10) + ((18 - 10)²/10) = 6.4 + 6.4 = 12.8
X² = 12.8
Freedom degrees = K – 1 = 2 - 1 = 1(K = Independent variables = dry cotton and wet cotton)
Significance level, 5% = 0.05 Table value/Critical value = 3.8412.8 > 3.84 meaning that the difference between the observed individuals and what the expected individuals in each chamber is statistically significant. Not probably to occur by random chances.
There is enough evidence to reject the null hypothesis.
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.

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.

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).

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.

What would the Earth be like if it had no atmosphere?
Answer:
It would be silent. Sound requires a medium to transmit waves. You could feel vibrations from the ground, but you wouldn't hear anything.
Birds and planes would fall from the sky.
The sky would turn black. It's blue because of the atmosphere.
It would be a vacuum so All plant and animal life on the Earth's surface would die.
Even if survive you'd get a massive sunburn on exposed skin because the Earth's atmosphere is what filters solar radiation.
