<span>When you put the cells in a salt solution you are placing the cells into a hypertonic solution. That means the solute concentration outside the cell is higher than the solute concentration inside the cell. You should know from your own studies that water will move from areas of high water concentration to areas of low water concentration. A hight solute concentration means there is low water concentration. That means that the water will move from the onion cell and out into the hypertonic solution and the onion cell will shrivel up.</span>

Trava [24]
In such a situation it would be best if Dr. Smith:

<span>''hire trained therapists who are from the same minority group''

This would have a wide ranging impact on the minority communities in the area.

Their participation would increase rapidly as their own community members would get the word out on the services provided and they might feel more comfortable in such an environment.

Since, mental health still has a stigma attached to it, especially in immigrant communities, this strategy would help to increase the level of mental health services provided to minority groups.

Jesse is studying a blood sample that has only antigen B on the red blood cells and antibody A in the plasma. What is the type o
lesya [120]

Answer:

Option: B+

Explanation:

The test to determine a blood group is called ABO typing. The blood sample is mixed with antibodies against type A and B blood. Then, the sample is checked whether or not the blood cells stick together. If blood cells stick together, it means the blood reacted with one of the antibodies.

B+ blood group:

A blood sample that has only antigen B on the red blood cells and antibody A in the plasma lies under B+ blood group.

B+ blood type means the person has antigen B and rhesus factor on RBC and could be able to receive blood from another B+ donor.

Please note:

As only antigen B is mentioned that is why we will consider B+ BLOOD group. Because negative antigen is not mentioned in the question and when there is no sign is mentioned we will consider it positive.

vesna_86 [32]

Answer:

Shivering thermogenesis.

Explanation:

The rate of heat production is increased by increasing muscle contraction by movement is shivering thermogenesis because nerve impulses are transmitted to the skeletal muscles by the hypothalamus which will result to contractions that will produce heat.

Shivering thermogenesis is Contraction-mediated heat production High intensity shivering activates large muscles and produce more glycolysis which is then use as the main source for heat production

Según la clasificación de ecosistemas, indica si los siguientes ejemplos de ecosistemas son correctos: Una piscina es un ecosist
Hatshy [7]

Answer and Explanation:

  • <em>Una piscina es un ecosistema acuático y seminatural: FALSO. </em>La piscina corresponde a un ecosistema acuático, siempre y cuando existan seres vivos habitando en ese medio e interactuando entre ellos y con los factores físicos como temperatura del agua, pH, etc. No corresponde a un medio seminatural porque su origen es totalmente artificial, es decir, hecho por el hombre.
  • <em>La pradera es un ecosistema terrestre y natural : VERDADERO. </em>Es terrestre por encontrarse en un espacio continental no inundable, y natural por no ser intervenido por el hombre.
  • <em>Un bosque nativo es un ecosistema terrestre y natural: VERDADERO. </em>Un bosque no es inundable, por lo que se considera netamente terrestre y mientras no sea intervenido por la acción humana es un ecosistema natural.<em> </em>
  • <em>Un arroyo es un ecosistema dulceacuícola y natural: VERDADERO. </em>Entre las posibles ubicaciones de un ecosistema acuático, se hayan aquellos que se encuentran en un medio de agua dulce, tales como arroyos, lagos, ríos, entre otros. Al no ser alterado por el hombre, se lo considera también un ecosistema de origen natural.    <em> </em>
  • <em>El mar es un ecosistema marino y artificial: FALSO. </em>El mar sí es un ecosistema acuático marino. Sin embargo no es un ecosistema alterado o creado por el hombre en forma artificial, sino que tiene un origen plenamente natural.
  • <em>Las ciudades son ecosistemas terrestres y seminatural: FALSO. </em>Pueden ser consideradas terrestres por estar ubicadas en el continente, pero son de origen artificial por ser creadas por el hombre.
  • <em>Las represas son ecositemas seminatural y acuático: VERDADERO. </em>Las represas son creadas en un medio natural que ha sido parcialmente modificado por el hombre, lo que las convierte en seminaturales. Corresponden a ecosistemas acuáticos de agua dulce.
