RNA splicing is an important stage in gene transcription. mRNA transfers the information from DNA to proteins. In many cases, this process creates multiple proteins from the same gene by varying the exon composition. This is called alternative splicing and can happen because exons are extended or skipped, or introns can be retained instead of being removed.
Alternative mRNA splicing is a mechanism in eukaryotes that allows for the production of different protein products from a single gene by combining different combinations of exons to form mRNA.
Explanation:Alternative mRNA splicing is a mechanism in eukaryotes that allows for the production of different protein products from a single gene by combining different combinations of exons to form mRNA. This process is a common mechanism of gene regulation, with the frequency of different splicing alternatives controlled by the cell. Approximately 70% of genes in humans are expressed as multiple proteins through alternative splicing.

What happens to the pressure inside a cell that is placed in a hypertonic solution?
A cell that is placed inside a hypertonic solution will lose water and become flaccid. If the situation persists for long, the cell would die.
Recall that osmosis is the movement of water molecules from the region of higher water potential (lower solute concentration) to the region of lower water potential (higher solute concentration) through a semi-permeable membrane.
A hypertonic solution has more concentration and, thus, lower water potential than the cell. This means that water will move osmotically from the sap of the cell to the surrounding hypertonic solution. In this case, the cell membrane would be acting as the semi-permeable membrane
When a cell continues to lose water, the turgor pressure inside the cell will reduce and the cell will go flaccid. If the water loss continues, the cell will die off.

about one in ____ individuals diagnosed with an eating disorder is male.
Further explanation
During this time, eating disorders are always associated with women. Some of the well-known eating disorders are bulimia and anorexia nervosa. In fact, eating disorders can also be experienced by men, both children and adult men.
Eating disorders in men were first recorded in the 16th century, precisely in 1689. At that time, the doctor from England, Richard Morton, noted two cases of anorexia nervosa in one male patient. Then in 1874, Ernest Charles Lasegue and Sir William Gull made another case report about men with anorexia nervosa.
after these early cases, men with eating disorders were considered "rare" until 1972 when Peter Beaumont and colleagues conducted research on anorexia nervosa in men. But now, a lot of research on the treatment of eating disorders that do not involve male subjects.
the total proportion of men with eating disorders is not known with certainty. Older statistics say 10 percent, but given the reluctance of men with eating disorders to admit that they have the problem, most experts believe the figure is higher.
The National Association for Males with Eating Disorders estimates that 25 to 40 percent of people with eating disorders are men.
Among other eating disorders, men have relatively more representation in the categories of binge-eating disorder and Avoidant Restrictive Food Intake Disorder (ARFID). Statistics show that about 40 percent of people with binge-eating disorders are men.

After a scientist finishes conducting an investigation, he or she is expected to publicly present the results. Why is it important for a scientist to communicate his or her results with other scientists?
Answer:
The correct answer will be- to evaluate the results and provide instructions to researchers.
Explanation:
A scientific method is a systematic approach to answer and understand the natural phenomenon.
The last step in the scientific method is to communicate the results with other scientists which could be done through publishing the results in peer-reviewed journals and presenting the results in conferences where the results could be discussed.
The scientist needs to share the results to scientists so that the scientific community can evaluate the results, as well as the results, provides the instructions to other researchers so that they can repeat their experiment.
Thus, to evaluate the results and provide instructions to researchers is the correct answer.

The complete and persistent absence of __________ is used to determine brain death.
Patients who have experienced a severe, irreversible brain injury with a known etiology should be evaluated for brain death.
What are the main sign and symptoms of brain death?Coma, the absence of brain stem reflexes, and apnea are the three key signs of brain death.
An assessment for brain death should be considered when a patient has suffered a serious, irreversible brain injury with a recognized etiology.
A patient who has been correctly deemed brain-dead is both legally and medically dead.
The apnea test is typically the last step in determining brain death. It is carried out after determining that a coma is irreversible, unresponsive, and that brain stem reflexes are absent.
Therefore, The completes and persistent absence of Brain stem reflexes, and apnea is used to determine brain death.

The cactus has a specialized fleshy stem and it's leaves function only for protection. Which plant tissues most likely makes up the stem?
The correct answer is vascular tissues.
Vascular tissues most likely form the stem. The prime vessels observed on the vascular tissue are the phloem and the xylem. These two tissues function as an element for the conduction of nutrients and water within the stem.
The xylem transports some nutrients and water from the roots, while the phloem transports the soluble organic constituents, which were generated at the time of photosynthesis from the leaves.
