Answer:
Las hormonas activan vías de señalización celular, con lo cual regulando el crecimiento, metabolismo y reproducción del organismo
Explanation:
Las hormonas son moléculas mensajeras que circulan a través del torrente sanguíneo para llevar a cabo diferentes funciones. Estas moléculas se unen a receptores específicos presentes en la superficie de las células con la finalidad de controlar diferentes aspectos de su funcionamiento. Las hormonas son principalmente producidas por glándulas endocrinas pero también pueden ser secretadas por células intersticiales y epiteliales.
Las hormonas se dividen cinco clases principales:
a- pequeños neurotransmisores implicados en el funcionamiento del sistema nervioso (gonadotropina, somatostatina)
b- derivados de aminoácidos que también tienen funciones neuromotoras (dopamina, catecolamina)
c- proteínicas asociadas a funciones metabólicas y del desarrollo (insulina)
d- hormonas esteroideas derivadas de colesterol (estrógenos) que regulan el desarrollo de las características reproductivas y metabólicas e inmunológicas
e- hormonas derivadas de vitaminas liposolubles A y D (retinoides) vinculados a mecanismos que previenen el envejecimiento celular
Determine whether the given procedure results in a binomial distribution (or a distribution that can be treated as binomial). If the procedure is not binomial, identify at least one requirement that is not satisfied. The YSORT method of gender selection, developed by the Genetics & IVF Institute, was designed to increase the likelihood that a baby will be a boy. When 150 couples use the YSORT method and give birth to 150 babies, the genders of the babies are recorded. Does the procedure represent a binomial distribution? A. No, because there are more than two categories for each trial. B. No, because the trials of the procedure are not independent. C. Yes, because the procedure satisfies all the criteria for a binomial distribution. D. No, because the probability of success differs from trial to trial.
Answer:
The correct answer is C)
Explanation:
The number of couples who used YSORT method (x) = 150That is, the number of couples who used YSORT method is limited or defined or definite.The probability of giving birth to a boy, for each couple is 1/2 or 0.5The gender of the baby born in each case mutually exclusive (Independent)
We can conclude that the procedure results in a binomial distribution because the assumptions of the binomial distribution are met.

During a routine physical exam of a child, the nurse notes an abdominal mass, elevated blood pressure and hematuria. The parents report abdominal pain, fatigue and recent fevers. Which lab value would prompt immediate further investigation and intervention?
Answer:
The signs that indicate immediate intervention would be a constant body temperature greater than 39 degrees, a decrease in blood pressure and heart rate, a decline, difficulty breathing, loss of consciousness.
If the chest pain increases, and the transaminase values also (liver evaluation) are also considered to be risk signs.
Explanation:
All these risk signs would be potentially lethal for the child but much faster than an adult, since it was found that children trigger acute lethal symptoms in less time, which is why the treatment should be done quickly and if possible As invasive as possible to reverse the picture.
The number of chromosomes during meiosis is incredibly important.why is that?
Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes, Meiosis also produces genetic variation by way of the process of recombination.
I hope this helps you
Meiosis refers to the process by which a single cell divides twice to produce four haploid daughter cells. These are the gametes, which are sperms in males and eggs in females.
Why the number of chromosomes is important during meiosis?Meiosis is a eukaryotic cell division process. However, the genetic material distributed among the resulting daughter cells is distributed in very different ways by these two processes.
Mitosis results in the formation of two identical daughter cells, each with the same number of chromosomes as the parent cell.
Meiosis, on the other hand, produces four distinct daughter cells, each with half the number of chromosomes as the parent cell.
Because meiosis generates cells that will become gametes (or reproductive cells), this reduction in chromosome number is critical; without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes.
Thus, we can conclude that the number of chromosomes during meiosis is incredibly important because It allows gametes to have half the original number of chromosomes of the organism.

Smurfs live in widely separated groups and rarely interbreed, so geneticists know very little about them. On one occasion, two smurfs from different groups did mate. A big-footed, white smurf mated with a small-footed, blue smurf. Three offspring resulted: one big-footed and blue and two small-footed and blue.Which statement about the inheritance of color in smurfs is most likely to be correct?
Answer:
See the answer below
Explanation:
The most correct statement would be that the blue color is dominant over the white color.
According to Mendelian law, when there are two different versions of the same gene/trait in which one is dominant and the other is recessive, the dominant version will be expressed while the recessive version only stays in the background.
In this case, the alternate versions of the same trait in the smurf are the white and blue colors. When they are mixed together in the offspring, the blue color is expressed and the white color stays in the background. It means the blue color is dominant over the white color.
Some viruses can be crystallized and their structures analyzed. One such virus is yellow mottle virus, which infects beans. This virus has a single-stranded RNA genome containing about 6300 nucleotides. Its capsid is 25-30 nm in diameter and contains 180 identical capsomeres.If the yellow mottle virus begins its infection of a cell by using its genome as mRNA, which of the following would you expect to be able to measure?
A) replication rate
B) transcription rate
C) translation rate
D) formation of new transcription factors
The correct answer is 9 proteins form each of the 20 facets of this virus. A capsid is the protein shell that surrounds a virus. A capsomere is the subunit of the capsid. Depending on the virus, capsomeres arrange in many different shapes to form the capsid. The yellow mottle virus has 20 facets, this means that it has an icosahedral capsid. Since it contains 180 identical capsomeres, we can conclude that 9 proteins form each facet.

Which organelles are found only in plant cells and not in animal cells?
Answer:
Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, which are not found within animal cells. The cell wall is a rigid covering that protects the cell, provides structural support, and gives shape to the cell.
How are plant and animal cells different?
Answer:
Plant cells have chloroplasts and a cell wall while animal cells don't. Animal cells are also more rounder, while plant cells have more of a rectangular box-like shape. There are more differences, but these are some of the main ones.
Hope this helped! :)
Answer:
The main difference between these cells is the that a plant cell has a cell wall and a rigid shape while an animal cell lacks a cell wall and its shape is circular.
Explanation: The plant cell has a robost and rigid shape due to the cellulose found in the cell wall. It's also important to note that a plant cell has a larger vacuole than that of an animal cell.

The fuel for nuclear power plants comes from
Answer:
Most nuclear reactors are fueled with a compound known as uranium dioxide. This uranium dioxide is put together in a fuel assembly and inserted into the nuclear reactor—where it can stay for several months or up to a few years. While in the reactor the fuel undergoes nuclear fission and releases energy
Explanation:
Answer:
Uranium is the most widely used fuel by nuclear power plants for nuclear fission. Nuclear power plants use a certain type of uranium—U-235—as fuel because its atoms are easily split apart. Although uranium is about 100 times more common than silver, U-235 is relatively rare at just over 0.7% of natural uranium.

A person in a dark room looking through a window can clearly see a person outside in the day light . But a person outside cannot see the person inside
Explanation:
The explanation for this is that the space outside is illuminated with light from the sun. The person inside has either a lesser or no illumination at all. The dark inside room appears dark, and darkens the surface of the window facing inside, making it act like the silvered surface of a mirror. When the outside observer looks at the window, the window acts as a mirror, reflecting the light from the sun onto the eyes of the outside observer. For the inside observer, some of the illumination from outside finds its way inside, since the outside window surface is well lit, carrying with it the sensation of vision onto the eyes of the inside observer.

Yes, the Clements successional theory been subjected to peer review and publication.
What is Clements successional theory?Plant succession was characterised by Clements as a developmental process that, during the course of a community, it went through a well-defined series of stages that, in the end, resulted in a mature community, also known as the climax community. The climatic conditions that determined the climax community's existence manifested themselves in the form of an indicator and an expression of that community.
His hypothesis of community formation, sometimes known as plant succession, is what brought Clements the most fame. Even after World War II, Clements' organicism and physiological perspective were still around, albeit in a watered-down version, despite the fact that it was extensively discredited by later ecologists.
