Answer:

Carbon that is used by producers, consumers and decomposers cycles fairly rapidly through air, water and biota. But carbon can also be stored as biomass in the roots of trees and other organic matter for many decades. This carbon is released back into the atmosphere by decomposition, as was noted before.

In the splicing step of gene expression, introns are spliced out, and exons are stitched together.

Gene expression refers to the process of protein synthesis that begins with a gene in DNA and finishes with a functional protein. The genetic code is translated to make protein during gene expression. Gene expression is a complex process that requires many different molecules, including RNA polymerases, transcription factors, and other regulatory proteins.

In eukaryotic cells, pre-mRNA is modified before it exits the nucleus. RNA splicing is a crucial aspect of pre-mRNA processing, in which non-coding introns are excised and exons are joined to produce mature mRNA molecules. The splicing process is carried out by a complex machinery consisting of small nuclear ribonucleoprotein particles (snRNPs).

The snRNPs in spliceosomes recognize introns and bring together the flanking exons for precise excision. Intron removal is followed by the ligation of exons, which results in the formation of a mature mRNA molecule that can be exported from the nucleus to the cytoplasm, where it can be translated into a functional protein.

Answer:

Yes.

Explanation:

PCR and STR analysis involve using specific markers to identify the presence of a person in a sample. PCR amplifies the DNA found in the skin cells and the STR analysis looks at the genetic profile of that individual. The combination of these two allows comparative analysis of the genetic profile between the suspect and the crime scene sample. If the biomarkers are similar enough, then one could conclude that the suspect was present at the scene.

Yes, specific markers are used in PCR and STR analyses to detect human presence in samples.

The DNA present in skin cells is amplified by PCR, and the STR analysis examines the individual's genetic profile.

When these two are combined, it is possible to compare the genetic profiles of the suspect and the sample from the crime site.

The suspect may have been present at the scene if the biomarkers are sufficiently comparable.

Investigators at crime scenes can extract DNA strains into levels that can be identified and linked to a suspect using PCR. To study gene function, evolution, and other subjects, biologists can make a few copies of character genes.

Therefore, through the use of PCR, tens of thousands of thousands of copies of a specific DNA sample may be produced in a matter of hours.

The coolest stars have wavelengths between 400nm and 500 nm. Thus the correct option is D.

Wavelength is defined as the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire.

A substance with 20 carbon-14 atoms will have only nitrogen - 14 left after over 5730 years due to radioactive decay.

The element carbon has a naturally stable isotope C- 12, but C -14 is the unstable isotope.

C - 14 is the most commonly consumed isotope of carbon by all living organisms. Radiocarbon dating is the process of determining the age of a sample by examining the existence half life-life of this element.

Both models refer to the population but in different ways. One major difference is that exponential growth starts slow then picks up as the population increases while logistic growth starts rapidly, then slows down after reaching the carrying capacity.

Answer:

Exponential growth has no furthest breaking point and populaces become rapidly. Logistic growth has a point of confinement and development approaches this cutoff in a sigmoidal manner. Logistic growth is more realistic, in actuality, yet exponential development is a superior model for bacterial societies, and so on that have boundless assets and space.

The solutions that would work better than the stamp act are:

Benjamin Franklin petitioned the British House of Commons, and the Stamp Act was repealed by a vote of Parliament. However, the Declaratory Acts were approved by Parliament the same day, stating that the British government possessed unrestricted and complete legislative authority over the colonies.

The Stamp Act imposed a tax on products inside the colonies, whereas the Sugar Act solely applied to imports. Internal taxes had hitherto solely been the responsibility of colonial assemblies.

Therefore, one can say that the Tea Act was enacted by the British Parliament in 1773 in an effort to salvage the struggling business. The act gave the firm permission to commission agents who would have the exclusive right to sell tea in the colonies and to send its tea directly to the colonies without first landing it in England.

The possible significance of some genes found in the eukaryotic genome also being found in bacteria and archaea is that they are likely related and evolved from a common ancestor.

This suggests that the shared gene may be of ancient origin and has been conserved in different lineages over time.

Many eukaryotic genes are found in both bacteria and archaea, suggesting a deep evolutionary relationship between the three domains of life. This can be observed in the conservation of certain gene families and the presence of similar gene structures between these domains.

By comparing the sequence and function of these shared genes, researchers have been able to identify common ancestors and explore the evolutionary history of these different domains. The possible significance of these shared genes is that they may have been conserved throughout time due to their importance for survival and the maintenance of cellular processes in both prokaryotes and eukaryotes.

Furthermore, this conserved gene can provide insight into the processes and structures present in the common ancestor, allowing for greater understanding of the evolutionary history of life on Earth.

Answer:

Substances in nature rarely exist as single element but combination of more than one elements.

This combination of element is referred to as compounds.

These compounds can breakdown from temperature change or change in pressure and so on ,these atmospheric change exist in nature and with long climatic change over a period and could lead to elements recombining and could be transported to other areas from weathering.

The posterior column-medial lemniscus pathway is responsible for carrying the sensations of discriminative touch and proprioception.

The sensations of discriminative touch and proprioception, which include the ability to perceive fine touch, pressure, vibration, and the awareness of body position and movement, are transmitted through the posterior column-medial lemniscus pathway.

The pathway begins with the sensory receptors located in the skin, muscles, tendons, and joints, which detect tactile and proprioceptive stimuli. The sensory information is then transmitted through peripheral nerves to the dorsal root ganglia, where the cell bodies of the primary sensory neurons are located.

From the dorsal root ganglia, the axons of the primary sensory neurons enter the spinal cord and ascend on the same side through the posterior columns, which are located at the back of the spinal cord. These axons synapse with secondary sensory neurons in the medulla oblongata.

The secondary sensory neurons decussate (cross over) to the opposite side of the brainstem and continue their ascent in a pathway called the medial lemniscus. The medial lemniscus carries the sensory information to the thalamus, specifically the ventral posterolateral nucleus.

Finally, the thalamus relays the sensory signals to the primary somatosensory cortex, where the sensations of discriminative touch and proprioception are processed and perceived.

In summary, the posterior column-medial lemniscus pathway is the fiber tract responsible for transmitting the sensations of discriminative touch and proprioception from the peripheral sensory receptors to the primary somatosensory cortex.

ANSWER C: SUBDUCTION IS THE CORRECT ANSWER

A subduction zone is located at a deep-ocean trench, it is a region in which one tectonic plate is sinking beneath another plate into the interior of the earth, hence option C is correct.

It is the region that is defined by the deep ocean trench and having lines of volcanoes situated parallel to these trenches, and also the zones of the earthquakes extended from trenches.

Oceanic trenches are trenches, which are prominent long, narrow topographic depressions of the ocean floor. Subduction zones are plate-tectonic boundaries where two plates converge, this creates earthquakes and volcanoes. This zone is formed when plates with thinner oceanic crust descend beneath a plate with thicker.
