Answer:

1. Isotonic

2. Hypotonic

3. hypertonic

4. hypotonic

5. Hypertonic

6. Hypotonic

Explanation:

Tonicity refers to the amount of the solute concentration dissolved in the solution which determines the direction of the diffusion across the semipermeable membrane.

There are three types of tonic solutions formed on the basis of solute concentration which are:

1. Isotonic solution: When the solute concentration is the same across both the sides of the semipermeable membrane. When a cell is placed in isotonic solution it remains in the same state as no movement of water is observed as in option 1.

2. Hypertonic solution: The solution which contains a high amount of solute and a low amount of water. When the cell is placed in this solution the cell shrivels as the water movement is observed from the cell to outside down the concentration gradient like in option-3 and 5.

3. Hypotonic solution: The solution which contains the low amount of solute and high amount of water, when a cell is kept in the hypotonic solution the cell swell and could become flaccid if is a plant cell as in option 2, 4 and 6.

A sorting device that is useful in classifying by observation is a _____. dichotomy wedge taxon key
baherus [9]
<h3><u>Answer</u>;</h3>

Key

A sorting device that is useful in classifying by observation is a <u>key</u>.

<h3><u>Explanation</u>;</h3>
  • <em><u>Classification key or taxonomic key is a device that is used by scientists to identify unknown organisms. </u></em>
  • They are constructed so that the user gets a series of choices about the characteristics of the unknown organisms.Thus, by making the correct choice at each step, one is led to the identity of the specimen.
  • Therefore<u><em>, keys can be used to identify a living organism or determine which group it belongs to</em></u> by answering questions on the key about characteristics of living things.

Why is it necessary to correct the readings of the respirometers containing seeds with the readings taken from respirometers con
amid [387]
So, the fact that it's a specific instrument doesn't change why you need to correct the data.
However, for this question it is important to know the instrumentation.
Since respirometers are measuring the <span>C<span>O2</span>:<span>O2</span></span><span> relation, clearly having biotic material and abiotic material will change the measurements.
You should be able to figure out that the general gas law is coming into effect because of the act of cellular respiration. In general terms, you are correcting your instrument to a known blank (you do this with scales and every other instrument).
By determining the reading for the blank (marbles) you can know the relative error of the instrument.
Taking a scale for example: You 0 the scale to a mass of importance (the amount of error you're okay with) and then use it for your measurements so you can be adequately confident of the mass you're measuring .</span>

1. El corazón se localiza en el __________________, que es el espacio comprendido entre ambos pulmones. 2. El __________________
IceJOKER [234]

Answer:

1. El corazón se localiza en el mediastino, que es el espacio comprendido entre ambos pulmones. 2. El  miocardio es la capa funcional del corazón, puesto que su contracción impulsa la sangre hacia los pulmones y los demás tejidos. 3. Internamente el corazón presenta 4 cavidades: 2 cavidades superiores llamadas auriculasy dos cavidades inferiores conocidas como ventriculos . 4. Entre la aurícula y ventrículo del mismo lado se encuentran las válvulas auriculoventriculares. En el lado derecho tenemos la válvula tricuspide, mientras que en el lado izquierdo se encuentra la válvula mitral . 5. El ciclo cardiaco comprende dos fases, una de contracción o sistole y una de relajación llamada diastole.

Explanation:

El corazon es un organo con un tejido muscular liso especializado donde estas celulas musculares presentan uniones desmosomales de amplia conexion para la diseminacion rapida de señales, es asi como se producen contracciones ritmicas, autonomas y de manera simultanea.

El corazon a su vez presenta su auto irrigacion propia por medio de las arterias coronarias que se encargan de mantener el miocardo en buen estado de vitalidad.
