what is Mycoplasam?(define it)
Explanation:
Mycoplasma: A large group of bacteria, with more than 100 types identified. Mycoplasma are very simple one-celled organisms without outer membranes. They penetrate and infect individual cells. Mycoplasma hominis and Mycoplasma pneumoniae are examples of mycoplasma bacteria that occur in humans.
(A) Mycoplasma pneumoniae cells (Gram stain). The signet-ring-shaped cell of Mycoplasma is gram-negative, and the size of the cell is 0.2–0.3 μm and is normally smaller than 1.0 μm. Cells have no cell wall.
What is the treatment for mycoplasma infection? Antibiotics such as erythromycin, clarithromycin or azithromycin are effective treatment. However, because mycoplasma infection usually resolves on its own, antibiotic treatment of mild symptoms is not always necessary.
Doxycycline is a tetracycline antibiotic that is used to treat susceptible bacterial infections of both gram-positive and gram-negative organisms, as well as infections caused by Mycoplasma, Chlamydophilia, and Rickettsia
Mycoplasma testing includes a group of tests that either measure antibodies in the blood produced in response to a mycoplasma infection or detect the microbe directly through culturing or by detecting its genetic material (DNA) in a body sample. It is most often used to detect Mycoplasma pneumoniae (M.28

A tube with a membrane covering the bottom is placed in a beaker. The membrane allows water to flow through but not salt or glucose. The tube contains an aqueous solution with 4% salt and 20% glucose and the beaker contains an aqueous solution with 12% salt and 6% glucose. How could you describe the solution in the beaker compared to the solution in the tube
Answer:
The solution in the tube is hypertonic to the solution in the beaker.
Explanation:
To compare the solutions, find the total amount of solutes in both the tube and beaker.
The tube has 4% salt and 20% glucose, so it has 24% solute.
The beaker has 12% salt and 6% glucose, so it has 18% solute.
Since 24 is larger than 18, this means the tube has more solute.
Since the tube has more solute and less water compared to the beaker, it is hypertonic to the beaker.
So, the answer is that the solution in the tube is hypertonic to the solution in the beaker.
Solutions are hypertonic or hypotonic to other solutions according to their solute concentration grade. In the exposed example, the beaker aqueous solution is hypotonic to the tube solution, meaning it is less concentrated.
--------------------
Available data:
The membrane allows water to flow through but not salt or glucoseThe tube contains an aqueous solution with 4% salt and 20% glucoseThe beaker contains an aqueous solution with 12% salt and 6% glucoseWe need to describe and compare solutions.
To do it, first, we will review some theoretical framework.
When talking about solutions in compartison with the cell content, we can classify them as follows,
• HYPERTONIC ⇒ A hypertonic solution has a higher concentration of solute than the cell. This means that in the cell interior, the solute concentration is lower than in the solution itself.
• ISOTONIC ⇒ The solute concentration is the same inside the cell and outside.
• HYPOTONIC ⇒ A hypotonic solution has a lower concentration of solute than the cell. This means that in the cell interior, the solute concentration is higher than in the solution itself.
When a cell is in a hypotonic solution, through osmosis, water moves toward the cell.
Osmosis is the phenomenon that occurs when two dilutions of different concentrations -in this example, the interior of the tube and the beaker- are separated by a semipermeable membrane.
The membrane allows the pass of water but not solute. Hence, water can move from the most diluted side to the less diluted one.
What we need to consider is
• When a cell with semipermeable membrane is placed in a hypotonic solution, water enters the cell.
• When a cell with semipermeable membrane is placed in an isotonic solution, there is no water movement.
• When a cell with semipermeable membrane is placed in a hypertonic solution, water gets out of the cell.
In simple words, in the proposed experiment, glucose and salt -solutes- can not cross the membrane, but water can. The tube represents a cell. So,
The tube has 4% salt and the beaker 12 % saltThe tube has 20% glucose and the beaker 6% glucose.To make the analysis easier, we can add the concentration percentages of glucose and salt at each side of the membrane, and then compare them.
The tube contains an aqueous solution with 24% solute (4% salt + 20% glucose)The beacker contains an aqueous solution with 18% solute (12% salt + 6% glucose)We can see that the concentration of solute is higher in the interior of the tube than in the beaker. This difference suggests that water will move forward to the tube interior.
According to this analysis, we can say that
The tube aqueous solution is hypertonic to the beaker solution → More concentratedThe beaker aqueous solution is hypotonic to the tube solution → Less concentrated---------------------------------------------

( ) Cuando un gen está ligado al cromosoma X con mecanismo de herencia recesivo, significa que el 100% de las mujeres pueden manifestar un fenotipo anormal. 3. ( ) Cuando un gen está ligado al cromosoma X con mecanismo de herencia dominante, significa que el 100% de los hijos varones de un hombre enfermo, pueden manifestar el fenotipo anormal. 4. ( ) En la herencia ligada al cromosoma Y, significa que el fenotipo anormal está presente en el 50% de las mujeres. 5. ( ) Dentro de las enfermedades ligadas al cromosoma Y se encuentra la hemofilia.
Answer:
1. Verdadero
2. Falso
3. Falso
4. Falso
5. Verdadero
Explanation:
Los seres humanos, como así también la mayoría de los mamíferos, poseen dos cromosomas sexuales: un cromosoma X y un cromosoma Y. Las hembras poseen 2 cromosomas X (un cromosoma X es heredado de la madre y el otro cromosoma X es heredado del padre); mientras que los hombres tienen un cromosoma X y un cromosoma Y (el cromosoma X es heredado de la madre, mientras que el cromosoma Y es heredado del padre). La hemofilia es una enfermedad recesiva monogénica ligada al cromosoma X, la cual está caracterizada por cuadros hemorrágicos causados por el déficit parcial y/o total de factores de coagulación. Los hombres expresan el fenotipo recesivo con mayor frecuencia que las mujeres para aquellos genes que se encuentran en el cromosoma X y poseen un mecanismo de herencia recesivo, esto debido a que los hombres sólo poseen una copia del alelo ligado al X (lo que hace que el alelo recesivo se exprese con mayor frecuencia en el fenotipo). De este modo, los hombres manifiestan hemofilia con mayor frecuencia que las mujeres porque en mujeres el gen recesivo necesita la presencia de dos copias del alelo defectuoso recesivo para que se exprese en el fenotipo hemofílico (es decir, las mujeres heterocigotas son portadoras de un alelo defectuoso pero no expresan la condición en el fenotipo), mientras que en los hombres la presencia de un sólo alelo defectuoso localizado en su único cromosoma X es suficiente para la expresión del fenotipo recesivo. En hombres, los genes ligados al cromosoma X son siempre heredados de la madre (los hombres heredan del padre el cromosoma Y). Finalmente, la herencia de caracteres ligados al cromosoma Y es muy rara porque los genes localizados en la región diferencial del cromosoma Y son escasos y estos genes solamente pueden ser trasmitidos de padres a hijos varones (ya que se encuentran en el cromosoma Y).

B. the forearm of different animals
C. the DNA of land animals
Answer:
the wings on bees and birds
An example of a homologous trait is the wings of bees and birds. The correct option is A.
What are homologous traits?The Theory of Evolution can be used to explain the homologous features of related species. According to this hypothesis, species develop over time from a common progenitor.
In order to adapt to the new environment, species separated from one another and developed new features. The variety of species observed on Earth today is the result of a process known as speciation.
The homologous features that are shared by related species are proof of their shared ancestry. For instance, despite being different, the wings of a bat and a bird share characteristics.
Therefore, the correct option is A. the wings of bees and birds.
