2.1explain the body's hormonal response to dehydration
Answer:
Vasopressin, a hormon is secreted by pituitary gland which is response to dehydration , causes kidney to excrete less water.
The body's hormonal response to the dehydration is the action of vasopressin in the kidney. The vasopressin decrease the work of the kidney and it leads to decrease the amount of water secreted by the kidney to save water in the body.
What is dehydration?Dehydration is a condition where there is less water present in the body. There are many reasons of dehydration, like drinking less water or diarrhea. All reactions of the body work by water. So loss of water severely affect the body.
The hormonal response to dehydration is the release of vasopressin by the pituitary gland of the body. The vasopressin saves water from the body to help body fighting with dehydration. It makes the kidney to filter less water.
Thus, the activation of vasopressin in the kidney causes the body's hormonal reaction to dehydration. Vasopressin lessens the kidney's workload, which causes a reduction in the amount of water the kidney secretes to conserve the body's water supply.

Durante la explosión de una planta nuclear como la ocurrida en Chernóbyl en 1986, una persona se expone por un tiempo a esta radiación ¿qué daños a nivel molecular (ADN O ARN) podría sufrir? Y ¿cómo afectaría esto su salud y a la de su descendencia?
Answer:
mediante mutaciones en el ADN
Explanation:
El desastre ecológico de Chernóbil estuvo asociado a la liberación de importantes cantidades de radiación en forma de radioisótopos hacia la atmósfera, como producto de la explosión de un reactor que contenía toneladas de uranio radiactivo. La exposición a este tipo de radiación aumenta las probabilidades de sufrir mutaciones en la molécula de ADN. Dicho de otro modo, la radiación incrementa las chances de sufrir cambios en el material genético hereditario. Las mutaciones generalmente son corregidas por los mecanismos de reparación del ADN; sin embargo, existen ocasiones donde las mutaciones no son reparadas. Por otro lado, las mutaciones a menudo tienen efectos deletéreos y por lo tanto están asociadas a enfermedades, ya que los cambios en la secuencia genética provocan consecuentemente también cambios en las proteínas codificadas por estos genes. Por ejemplo, las mutaciones sufridas por genes supresores de tumores se encuentran asociadas a la aparición de células cancerosas por el mal funcionamiento de dichos genes. El efecto de la mutación depende del tipo celular que sufre la mutación: aunque las mutaciones sufridas por células somáticas pueden afectar la salud, estos tipos de mutaciones no son heredadas (simplemente porque las células somáticas no se heredan), mientras que las mutaciones sufridas por células germinales, es decir, en las células encargadas de la formación de gametos, pueden ser transmitidas a la descendencia.

The following is a list of the steps that occur in the production of an auditory sensation. 1. The pressure wave distorts the basilar membrane on its way to the round window. 2. Movement of the tympanic membrane causes displacement of the malleus. 3. Displacement of the stereocilia stimulates sensory neurons of the cochlear nerve. 4. Movement of the malleus causes movement of the incus and stapes. 5. Distortion of the basilar membrane forces the hair cells of the organ of Corti toward or away from the tectorial membrane. 6. Movement of the oval window establishes pressure waves in the perilymph of the vestibular duct. The proper sequence for these steps is:___________.A. 2,4,1,6,5,3B. 2,4,6,3,5,1 C. 2,1,4,6,5,3D. 2,4,6,1,5,3E. 2,5,4,6,1,3
Answer:
The correct answer is option D, that is, 2,4,6,1,5,3.
Explanation:
With the approaching of sound waves, ear pinna mediates it towards the external auditory canal, this makes sound waves to reach the tympanic membrane. This results in the vibration of the tympanic membrane, and as the malleus, that is, the first ear ossicle, which is attached to the tympanic membrane gets displaced.
This movement of the malleus further moves the stapes and the incus. As the footplate of the stapes is associated with the oval window, the movement of the oval window takes place. This movement of the oval window creates pressure waves in the vestibular duct's perilymph. The movement of these pressure waves takes place from the Oval window to the Round window.
At the time of this movement, the pressure wave distorts the basilar membrane on its path to the round window, resulting in the vibration of the basilar membrane and the hair cells situated in the membrane against the tectorial membrane.
The stimulation of the sensory neurons takes place in the vestibulocochlear nerve's cochlear branch due to the displacement of the stereocilia. Post this, information reaches the auditory cortex in the temporal lobe's superior temporal gyrus, and hearing takes place.
Option D is the one that shows the correct sequence of steps in an auditory sensation. In this case, the sequence is 2,4,6,1,5 and 3.
We can arrive at this answer because:
At the beginning of auditory sensation, the pinna turns to the external acoustic meatus, directing the sound waves to the tympanic membrane.These waves provoke an intense vibration in the tipanic membrane, which provokes the displacement of the malleus.The displacement of the malleus causes a movement that also displaces the stapes, the incus, and the oval window.The movement of the oval window causes other waves that press against the round window.This causes the basilar membrane and hair cells to vibrate, causing stimulation of sensory neurons.At that point, auditory information reaches the auditory cortex in the temporal lobe, allowing hearing to take place.

1.What is meant by Plasma therapy ? Is it a remedial treatment for Coronavirus? Express your answer with valid points
Answer:
It is a therapy that involves the use of plasma from recovered patients (which is composed of antibodies against the virus)
Explanation:
The immune system of patients already recovered from viral diseases naturally generates defensive molecules that circulate in the blood. These molecules are known as 'antibodies', and they are localized in the plasma of the blood, which is composed of coagulation factors, albumin, fibrinogen and, of course, antibodies. These antibodies bind to specific viral antigens in order to promote their neutralization and destruction. In consequence, the plasma from recovered patients contains particular antibodies that may be used to treat specific diseases.

Explain how a person can be a carrier for a sex-linked disorder, but not exhibit this disorder.
A person cannot exhibit the disorder because they don't experience the condition because they have a healthy copy of the gene on their other sex chromosome.
A disorder is a functional abnormality or disturbance that affects an individual's physical, mental, or emotional health.
They have the potential to pass on the mutated gene to their offspring, but they do not exhibit the disorder themselves because they have a normal copy of the gene on their other sex chromosome.
In the case of X-linked disorders, females have two X chromosomes, while males have one X chromosome and one Y chromosome. Females can be carriers for X-linked disorders if they inherit one mutated X chromosome from one parent, and one normal X chromosome from the other parent.
Males, on the other hand, cannot be carriers of X-linked disorders because they only have one X chromosome.
Therefore, a person can be a carrier for a sex-linked disorder if they have one copy of a mutated gene on one of their sex chromosomes, but not on both.

Answer:
3: A device that uses radioactive fluid to determine the active areas of the brain
Explanation:
A positron emission tomography (PET) scan is an imaging test that helps reveal how your tissues and organs are functioning. A PET scan uses a radioactive drug (tracer) to show this activity. This scan can sometimes detect disease before it shows up on other imaging tests.
Depending on the type of exam, the radiotracer is injected, swallowed or inhaled as a gas. It eventually accumulates in the area of the body under examination. A special camera or imaging device detects radioactive emissions from the radiotracer. The camera or device produces pictures and provides molecular information.

Glaucoma is a leading cause of blindness. Studies have linked a common form of glaucoma to three genes and more than 20 genetic loci. Which best describes glaucoma?
Answer
(A) - a recessive trait that requires multiple recessive alleles to be expressed
Explanation:
Glaucoma is a polygenic trait influenced by the alleles of several genes.
Polygenic phenotypic traits are those influenced by many genes, which interact to shape the phenotype. Polygenic traits exhibit a bell-shaped distribution in a population (i.e. they have a continuous distribution). Some examples of polygenic traits include, among others, height, body shape, skin color, weight, etc.A polygenic trait that is also affected by environmental factors is known as a multifactorial trait.In conclusion, glaucoma is a polygenic trait that is influenced by the alleles of several genes.

What is Deforestation?Deforestation also known as forest clearance is defined as the removal of forest or stands of trees from land that is converted to non-forest use in which forest land is converted into farms, ranches or urban may involve converting to use. The most concentrated deforestation occurs in tropical rainforests.
It occurs when humans remove or thin forests for timber or use land where trees stand for crops, grazing, extraction such as mining, oil, or gas, or as populations grow and people move. Development takes place in the form of migration.
Wildlife habitats are fragmented due to deforestation, where native species have to live on remaining habitat islands that are surrounded by disturbed land being used for agriculture and other uses.
