You are testing learning and memory in two strains (A and B) of hamsters by determining which hamsters learn and remember how to navigate a maze better. You discover that a strain of hamsters raised in a diverse environment has enhanced memory compared to a strain of hamsters raised in a bare cage. You look at a specific gene that is involved in brain development and is activated during learning and memory. If you use bisulfite treatment and subsequent sequencing to study the methylation pattern is of the promoter for this gene, you find that at the same region of the promoter sequence:
Strain A has the following bisulfite treated sequence: GTACGTTAAACGATCG
Strain A has the following untreated sequence: GTACGTTAAACGATCG
Strain B has the following bisulfite treated sequence: GTATGTTAAATGATTG
Strain B has the following untreated sequence: GTACGTTAAACGATCG
Based on the sequences above, greater levels of transcription for this learning and memory gene more likely occur in which of the strains?
Answers
Answer:
The correct answer is - Strain B.
Explanation:
The methylation process is adding the methyl group to the DNA molecule that can alter the activity of the DNA segment without any change in the sequence. Methylation presence in the promotor in a gene can repress the transcription process.
By the sequence given it is clear that strain B is not treated and less likely to methylated whereas strain B is more likely to methylated so the greater transcribe sequence would be - Strain B.

Sometimes an organ can be replaced by moving it from one part of the body to another. This can be done, for example, to replace damaged skin or joints. In these cases: rejection of the transplanted organ would not be expected. antibodies would be generated against the transplanted organ. antigens would be generated against the transplanted organ. immunosuppressant drugs would be required to prevent transplant rejection. rejection of the transplanted organ would still be expected.
Answers
Answer:
rejection of the transplanted organ would not be expected.
Explanation:
Organs can be defined as specialized body tissues united to perform specific functions in living organisms. Some examples of organs found in humans are brain, bladder, kidney, heart, intestine, eyes, lungs, liver, etc.
In the field of Medicine and Surgery, an organ is sometimes replaced for specific reasons, by moving it from one part of the body to another; this process is generally referred to as a transplant. Thus, it's mainly done to replace damaged skin or joints in the body of a living organism such as humans.
Hence, in these cases, rejection of the transplanted organ would not be expected because an examination and matching of the organ is carried out by the medical professionals before transplant.

Answers
Answer:
1. nerve stimulus
4. calcium channels open
10. acetylcholine vesicles move to endplate
7. exocytosis occurs releasing acetylcholine into synaptic cleft
3. acetylcholine binds to receptor
6. impulse rides along sarcolemma
9. impulse enters the cells via the t-tubule
5. sarcoplasmic reticulum releases calcium
8. calcium binds to troponin moving tropomyosin out of the way
2. myosin attaches to actin causing a twitch
Explanation:
The central nervous system generates an action potential (1) that travels to the muscle fiber activating the calcium channels (4). Calcium triggers vesicles fusion to the presynaptic membrane (10) releasing acetylcholine (Ach) into the synaptic space (7). Once there, Ach binds to its receptors (3) on the postsynaptic membrane of the skeletal muscle fiber, causing ion channels to open. Positively charged sodium ions cross the membrane to get into the muscle fiber (sarcoplasm) and potassium leaves the cell. The difference in charges caused by these ions transport charges positively the muscle fiber membrane (6). It depolarizes. The action potential enters the t-tubules (9) depolarizing the inner portion of the muscle fiber.
Contraction initiates when the action potential depolarizes the inner portion of the muscle fiber. Calcium channels activate in the T tubules membrane, releasing calcium into the sarcolemma (5). At this point, the muscle is at rest, and the tropomyosin is inhibiting the attraction strengths between myosin and actin filaments. Tropomyosin is obstructing binding sites for myosin on the thin filament. When calcium binds to troponin C, troponin T alters the tropomyosin position by moving it and unblocking the binding sites (8). Myosin heads join to the uncovered actin-binding points forming cross-bridges (2), and while doing so, ATP turns into ADP and inorganic phosphate, which is released. Myofilaments slide impulsed by chemical energy collected in myosin heads, producing a power stroke. The power stroke initiates when the myosin cross-bridge binds to actin (2). As they slide, ADP molecules are released. A new ATP links to myosin heads and breaks the bindings to the actin filament. Then ATP splits into ADP and phosphate, and the energy produced is accumulated in the myosin heads, which starts a new binding cycle to actin. Finally, Z-bands are pulled toward each other, shortening the sarcomere and the I-band, producing muscle fiber contraction.

Use the scenario to answer the following question.
A forest ecosystem is home to mountain lions, coyotes, bobcats and deer.The deer eat grass. The mountain lions, coyotes, and bobcats eat deer. Hunters began killing large numbers of mountain lions, coyotes, and bobcats. About twenty years later, the deer population had largely increased. The teacher asked the students to explain why the population of deer had a large increase in population size.
Which student’s argument MOST accurately explains the increase in the deer population?
A. Student 2: The number of deer increased because without mountain lions, coyotes, and bobcats, the deer lived longer and had more offspring that also lived longer.
B. Student 3: The number of deer increased because with fewer mountain lions, coyotes, and bobcats, the deer had more food available to eat.
C. Student 1: The number of deer increased because deer populations are always increasing, even when there are mountain lions, coyotes, and bobcats preying on them.
D. Student 4: The deer population increased because with fewer mountain lions, coyotes, and bobcats, there was less competition within the deer population.

Genetic engineering techniques can be used when analyzing and manipulating DNA and RNA. Scientists used gel electrophoresis to study transcription of gene L and discovered that mRNA strands of three different lengths are consistently produced. What explanations best accounts for this experimental result?
Answers
Answer:
the precursor messenger RNA (pre-mRNA) of the L gene underwent alternative splicing, thereby producing three different mRNAs that have different lengths
Explanation:
In eukaryotic organisms, transcription produces a precursor mRNA (pre-mRNA), which is a non-processed RNA sequence that contains both non-coding regions (i.e., introns) and coding regions (i.e., exons). Subsequently, this pre-mRNA is converted into a mature messenger RNA (mRNA) by a process known as 'alternative splicing', where introns are removed and exons and exons spliced together to form a contiguous coding sequence. During alternative splicing, differential combinations of exons can be produced from the same gene, producing different mRNAs with different lengths.
The experimental results with the gel electrophoresis of the transcription of mRNA are due to the alternative splicing.
What is alternative splicing?The genes are the codes that are enabled the formation of the DNA and RNA by expression. The transcription is the process of formation of mRNA from DNA template.
The mature mRNA is formed by the alternative splicing of the introns and the joining of exons for the functionalization. The process of alternative splicing results in the formation of the mRNA of multiple length.
The gel electrophoresis bands resulted have multiple length of mRNA. The results are the explanation for role of gene L in alternative splicing of mRNA.

g John Smith is a pig farmer. For the past 5 years, Smith has been adding vitamins and low doses of antibiotics to his pig food; he says that these supplements enhance the growth of the pigs. Within the past year, however, several of his pigs died from infections of common bacteria, which failed to respond to large doses of antibiotics. Can you explain the increased rate of mortality due to infection in Smiths pigs
Answers
Answer:
Due to tolerance against antibiotic.
Explanation:
The increased rate of mortality occurs in the pigs due to the bacteria which gets tolerance against the antibiotics. The regular use of same antibiotic kills most of the bacteria but in some bacteria mutation occurs that produces tolerance against the antibiotics and there is no effect of antibiotics on then and they are able to cause infection in the organism that leads to death. So the use of same antibiotics is not good for the pigs, the pig farmer should apply different type of antibiotics due to which the bacteria has zero tolerance.

Answers
Answer:
A. Homologue.
B. Chiasma.
C. Synaptonemal.
D. Synaptonemal.
E. Synapsis.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
Synaptonemal complex can be defined as a network of proteins that is responsible for holding homologous chromosomes (homologues) together.
Generally, a synaptonemal complex (protein lattice) is formed between homologous chromosomes during mitosis and meiosis. Also, synaptonemal complex is important for the formation of the four sister chromatids referred to as tetrads.
Furthermore, the synaptonemal complex (protein lattice) has a tripartite structure which comprises of the following components;
I. SC protein-1 (SYCP1).
II. SC protein-2 (SYCP2).
III. SC protein-3 (SYCP3).
In conclusion, the synaptonemal complex plays a significant role in synapsis, recombination and chromosome pairing.
Matching the various terminologies in genetics with their description, we have;
A. Homologue: one of a pair of chromosomes with similar genetic information and from different sources like the sperm and egg.
B. Chiasma: several X-shaped structures may be visible under the microscope and indicate where crossing over has occurred.
C. Synaptonemal: a lattice of protein holds two replicated chromosomes in precise register with one another.
D. Synaptonemal: four chromatids are held together by a zipper-like structure.
E. Synapsis: a process in which pairs of homologous complex chromosomes line up side by side.

What would cause a person to have two copies of the bent thumb allele (tt)?
1. A person whose mother or father had two copies of the bent thumb allele will always have two copies of the allele.
2.A person with two copies of "t" inherited one from their mother and one from their father.
3. A person born with one "t" mutation is more likely to develop a second "t" mutation during their lifetime.
4. A person with two copies must have duplicated the "t" allele through mitosis early in development. (They inherited one, then doubled it)
Answers
Answer:
A person with two copies of "t" inherited one from their mother and one from their father
Explanation:
