The rectus abdominis is a Parallel muscle, while the rectus femoris is a bipennate muscle.

<h3>Rectus abdominis</h3>

The long muscle of the anterior abdominal wall is the rectus abdominis, most commonly referred to as the "abs muscle." It is readily apparent beneath the skin, forming the "six pack," in people with low body fat. It reaches all the way to the pubic bone from the rib cage. Together with the pyramidalis muscle, the rectus abdominis is a member of the anterior abdominal muscles. However, when considering the functional architecture, these two muscles together with the three lateral abdominal muscles—the external oblique, internal oblique, and transversus abdominis—make up the anterolateral abdominal wall. The rectus sheath, which is made up of the aponeuroses of the lateral abdominal muscles, surrounds and protects the rectus abdominis muscle. The linea semilunaris is the outside, most lateral line defining the rectus.

Los métodos hormonales son eficientes porque: * A: impiden la entrada de los espermatozoides C: Se inhibe (no se desarrolla) la
timofeeve [1]

Answer: C: Se inhibe (no se desarrolla) la ovulación.

Explanation:

Los métodos anticonceptivos se utilizan prevenir el embarazo no deseado, evitando que el esperma fertilice a un óvulo. Hay distintos tipos, los cuales se clasifican en:

  • Anticonceptivos hormonales: Contienen hormonas, tales como estrógeno y progesterona, que previenen la ovulación (es decir, la liberación de óvulos de los ovarios). De esta manera, al no haber óvulo disponible, por mas que hayan espermatozoides, no va a ocurrir ninguna fecundación. El método mas conocido es la píldora o pastilla anticonceptiva.
  • Anticonceptivos de barrera: Proveen una barrera física que impide la fecundación al impedir el encuentro entre el óvulo y el espermatozoide. Por ejemplo, el uso de preservativos o condones. En estos métodos, se impide la entrada de los espermatozoides, no se encuentran con el óvulo y la esperma queda atrapada dentro del condón.
  • Anticonceptivos permanentes: Proveen un método permanente como  por ejemplo el Dispositivo Intrauterino que se coloca en el tracto uterino con una vida media de meses o años y posee un efecto espermicida que mata a los espermatozoides (por lo que no lograrán encontrar un óvulo). Otro ejemplo es la vasectomía, la cual es una cirugía que corta los conductos deferentes que transportan a los espermatozoides por lo que ya no pueden salir de los testículos para producir la fecundación (quedan atrapados dentro de los testículos, no entran al tracto uterino y no encuentran al óvulo)

Tanto los métodos de barrera como los permanentes, no inhiben la ovulación aunque si impiden que el óvulo se encuentre con el espermatozoide. <u>Entonces, los métodos hormonales son los únicos que logran inhibir la ovulación</u>. Las píldoras que poseen las hormonas previamente mencionadas pero fabricadas sintéticamente. Las mismas mimetizan el efecto de las hormonas naturales producidas por el cuerpo, alterando el ciclo menstrual regular y así evitan el embarazo ya que no habrá óvulo disponible para fecundar. Además, también pueden alterarla mucosidad en el cuello del útero para que los espermatozoides no pueden atravesarlo y llegar al óvulo. De todas maneras, el objetivo principal y mas importante de los métodos hormonales es bloquear la ovulación.

How virus shows both living and nonliving characteristic???​
Damm [24]

Answer:

Please find the explanation below

Explanation:

Virus is an organism that has been a topic of debate in biological sciences. This debate is based on whether virus should be classified as a living thing or not. However, it has been shown that viruses possess characteristics or properties of both living and non-living things.

The living thing characteristics include;

- Ability to reproduce or replicate (in living cells only and not on their own).

The nonliving characteristics include;

- Lack of cells, which is a strong criterion for every living thing in accordance to the universal cell theory.

- Inability to self-replicate i.e. reproduce on their own without a living host.
