En la ÓSMOSIS, un disolvente (a menudo agua) se mueve desde una zona de baja concentración de solutos hacia una zona de alta con

centración de solutos, a través de una membrana semipermeable. Aquí, las moléculas de agua se difunden en la disolución concentrada de azúcar debido a que son lo suficientemente pequeñas como para poder moverse a través de la membrana; las moléculas de azúcar, de mayor tamaño, son incapaces de atravesarla. La ósmosis finaliza cuando las dos disoluciones alcanzan la misma concentración a cada lado de la membrana. La tendencia natural de las moléculas a moverse desde zonas de alta concentración hacia zonas de baja concentración se llama DIFUSIÓN.
Si una célula animal se coloca en una solución cuya
concentración de sustancias disuelta es más alta que el interior de la célula
A: La célula se hinchará
B: la célula se vuelve impermeable
C: La célula se encogerá
D: La célula conservara su tamaño

Answer:

C

Explanation:

This is placing a cell in hyper tonic solution.Therefore, the water potential of the cells is higher than the environment. Hence it lose water to the environment which has a  lower water potential, but higher solute potential.

Therefore the loss of fluid by the cell leads to shrinking of the cytosol and it containing organelles. Later the cells collapse.

<u>Spanish</u>

Esto es colocar las células en una solución hipertónica. Por lo tanto, el potencial hídrico de las células es mayor que el del medio ambiente. Por lo tanto, perder agua al medio ambiente reducirá el potencial hídrico, pero aumentará el potencial de soluto.

Por lo tanto, la pérdida de líquido por parte de la célula conduce a la contracción del citosol y que contiene orgánulos.

(opening the door) describe the work of at least 3 body organ Systems that work during the process.
My name is Ann [436]
Explanation:

When a person opens the door, he or she uses 3 systems:

1. Nervous system: from the nervous system, neural instructions are generated through electrical impulses towards the muscles of the upper limb so that they make the necessary movements to open the door.

2. Muscular system: through the muscles of the trunk and the upper limb, it generates voluntary movement to open the door.

3. Skeletal system: the bones are the support of the soft tissues and the fulcrum of most of the skeletal muscles. In this sense, it serves as a support for the muscles of the trunk and the upper limb to carry out the movement of opening the door.

we can conclude that the correct answer is:

Answer:

1. Nervous system: instructions are generated from the nervous system by means of electrical impulses towards the muscles of the upper limb so that they carry out the necessary movements to open the door.

2. Muscular system: the muscles of the trunk and the upper limb generate voluntary movement to open the door.

3. Skeletal system: it supports the muscles of the trunk and the upper limb to carry out the door opening movement. It also has joints that help the mechanical movements necessary to open the door.

A laboring client who is positive for group B Streptococcus (GBS) is given an initial dose of 2 g of ampicillin at 9 AM. Accordi
Vikki [24]

Answer:

The next dose will be 1 g of ampicillin after 4 hours.

Intrapartum antibiotic administration to women with group B that tested ampicillin or penicillin G, either antibiotic should first be considered for(2 g of ampicillin IV followed by 1 g every four hours until giving birth.

Explanation:

Group B streptococci (GBS) colonizes the vagina and rectum in 10–30% of pregnant women.1 In the newborn, GBS is a leading cause of neonatal sepsis and a major cause of pneumonia and meningitis.2

In 2002, the Centers for Disease Control and Prevention (CDC) issued guidelines to recommend that all pregnant women be screened at 35–37 weeks of gestation for GBS and, if positive, treated with intrapartum antibiotic prophylaxis. The aims of prophylaxis are 1) to decrease colony counts at the time of delivery; 2) to prevent the organism from ascending and proliferating in the amniotic fluid compartment; and 3) to achieve adequate levels of effective antibiotic in the fetal bloodstream during labor.

For Ampicillin  nonallergic patients, the protocol recommends a 2 g unit infusion of ampicillin, followed by 1 g  every 4 hours until delivery.3 At least 4 hours of intrapartum antibiotic prophylaxis are recommended.
