Which model shows the correct polarity of double-stranded dna?.

The cortical magnification factor occurs in humans because, a small area in the peripheral retina accounts for a large area on the cortex. The answer to this question is option A.

The cortical magnification factor is the phenomenon where small areas in the peripheral retina account for large areas on the cortex. This means that certain areas of the retina, such as the fovea, are more sensitive to light and can capture finer details. As a result, these small areas are given more processing power in the brain, resulting in a larger representation on the cortex.The other options provided in the question are not correct. The small area of the fovea does account for a large area on the cortex, but this is not the reason for the cortical magnification factor.

The area at the optic disk is not involved in cortical magnification, and the lens accommodates to adjust focus on the retina, not to magnify the image. The cortical magnification factor occurs in humans because the small area of the fovea accounts for a large area on the cortex.  This increased processing results in a larger cortical representation for the fovea, leading to the cortical magnification factor.

Answer:

1. Transcription begins when RNA polymerase binds to a promoter sequence near the beginning of a gene (directly or through helper proteins). RNA polymerase uses one of the DNA strands (the template strand) as a template to make a new, complementary RNA molecule. Transcription ends in a process called termination. 2. DNA polymerase 3. Before mRNA leaves the nucleus of a eukaryotic cell, a cap is added to one end of the molecule, a poly A tail is added to the other end, introns are removed, and exons are spliced together. Sequence of nucleotides in messenger RNA is translated into a sequence of amino acids. 4. In RNA splicing, specific parts of the pre-mRNA, called introns are recognized and removed by a protein-and-RNA complex called the spliceosome.

Explanation:

I hope this helps. ^_^

Transcription is the technique of creating an RNA replica of a gene series. This replica, known as a messenger RNA (mRNA) molecule, leaves the molecular nucleus and enters the cytoplasm, wherein it directs the synthesis of the protein, which it encodes.

Thus it is clear that all answers are well explained.

The invention of the power loom was as socially transformative as the domestication of horses.

The invention of the power loom was a key technological advance that had a profound impact on society. Like the domestication of horses, it allowed for significant increases in productivity and efficiency, leading to major social and transformative economic changes. The power loom revolutionized the textile industry, making it possible to produce large quantities of cloth quickly and inexpensively. This had far-transformative effects on many aspects of society, including the growth of cities, the rise of the middle class, and the development of new forms of labor and leisure. The power loom also played a role in the industrial revolution, making it one of the most important inventions in human history and one that can be compared to the transformative impact of the domestication of horses.

Answer:

Amino acids are building blocks to proteins, and the combination and order of them determines what protein is actually being built. Then enzymes are a type of protein which facilitates or catalyses a process, such as the breaking down of molecules in your food. In a viral takeover, the virus uses your body's ribosomes to create viral proteins (consisting of amino acids). Viral enzymes actualy facilitate this by inserting viral DNA into the hostcell's DNA.

Explanation:

Reverse faults occur at transform boundaries and Strike-slip faults occur at divergent boundaries.

Sudden movement along Earth's fault lines causes earthquakes. The motion releases "elastic strain" energy that has been accumulated inside the form of seismic waves, that travel through the Earth & cause the earth to tremble. A mid-ocean ridge, or underwater mountain system created by plate tectonics, is what is referred to as the Mid-Atlantic Ridge (MAR). The "elastic rebound theory" for earthquakes refers to this steady buildup & release of stress and strain. Reverse faults happen at convergent borders whereas normal faults happen at divergent boundaries.The abrupt elastic rebounding of previously energy stored is what causes most earthquakes. Tectonic plates, which are huge chunks of the lithosphere of the Earth, split away from one another during the geologic process of seafloor spreading.

Explanation:

The correct option is E, Infection by Yersinia pestis, the bacterium responsible for causing the plague, can result in the formation of a characteristic lesion known as a bubo.

Infection refers to the invasion and multiplication of harmful microorganisms, such as bacteria, viruses, fungi, or parasites, in the body. These microorganisms have the potential to cause damage to the host organism's tissues and disrupt normal bodily functions. Infections can occur in various parts of the body, including the skin, respiratory tract, urinary tract, gastrointestinal tract, or bloodstream.

The process of infection typically involves the introduction of the pathogen into the body through various means, such as inhalation, ingestion, or direct contact with infected surfaces or individuals. Once inside the body, the pathogen begins to replicate and spread, often triggering an immune response from the host's immune system.

The correct sequence that reflects the locations a secretory protein will visit on its way from its production to its secretion outside the cell is: **Rough ER, Golgi complex, Secretory Vesicle.**

First, the secretory protein is synthesized by ribosomes on the rough endoplasmic reticulum (RER). Here, the protein undergoes folding, modification, and processing to ensure its proper structure and function. Once synthesized, the protein is transported from the RER to the Golgi complex. In the Golgi complex, the secretory protein undergoes further processing, including sorting and packaging into secretory vesicles. These vesicles then transport the protein to the plasma membrane for secretion outside of the cell. Smooth endoplasmic reticulum (SER) and ER vesicles are not directly involved in the secretion pathway of secretory proteins. However, SER is involved in lipid synthesis and metabolism, while ER vesicles transport proteins between the ER and the Golgi complex.

Question 7: MASP-1/MASP-3 of the Lectin pathway of the complement system cleaves C2. The correct answer is option (a).

Question 8: IL-1 and Tumor Necrosis Factor (TNF) are induced by C5a. The correct answer is option (d).

Question 6: Alternative splicing refers to the process by which multiple mRNA transcripts can be generated from a single gene, resulting in different protein isoforms. In this case, the alternative splicing of the MASP-2 gene is related to the protein associated with ficollins and MBL (mannose-binding lectin), but it is not an enzyme. Among the given options, the correct answer is (d) sMAP19.

Question 7: The Lectin pathway is a part of the complement system, a series of proteins that play a crucial role in the immune response. MASP-1/MASP-3, two serine proteases, are involved in this pathway. They cleave C2, leading to the activation of downstream complement components. Therefore, the correct answer to this question is (a) C2.

Question 8: IL-1 and Tumor Necrosis Factor (TNF) are pro-inflammatory cytokines that play important roles in the immune response. They can be induced by various factors. Among the given options, the correct answer is (d) C5a. C5a is a component of the complement system that is generated during complement activation. It acts as a potent inflammatory mediator and can induce the production of IL-1 and TNF.

In summary, the alternative splicing of the MASP-2 gene is related to sMAP19 (option d). MASP-1/MASP-3 cleaves C2 (option a), and IL-1 and TNF are induced by C5a (option d).
