Why is it necessary to correct the readings of the respirometers containing seeds with the readings taken from respirometers con

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>

Intermediate photographs should show the relation of evidence to other parts of the crime scene. A. True B. False​
hichkok12 [17]

Answer:

True.

Explanation:

<em>"adjective </em>

<em>adjective: intermediate </em>

<em>coming between two things in time, place, order, character, etc."</em>

Pictures correlating to the crime scene are like puzzles to find out the other meanings or cause of another picture.

For example:

A opened jug of milk sits on a table.

There's a blurred figure of a hand hitting the jug.

The jug is now laying on the table, dripping everywhere.

-

If we take out the middle picture "There's a blurred figure of a hand hitting the jug.", then we would not know what hit it over. Did someone bump into the table? Did a cat climb onto the table and release its almighty strength onto it? All we would know that it was once standing upright.

TLDR; Without intermediate pictures, it would be hard to grasp what happened on the scene. Intermediate pictures all have something in common with each other to help interpret what occurred to the viewer.

Flatworms are the first organisms we have discussed with an anterior-posterior orientation. How does this affect their movement
Talja [164]
<h2>Anterior-posterior orientation</h2>

Explanation:

Flatworms have an anterior-posterior orientation and as a result more coordinated and deliberate movement is established  

  • Flatworms also called Platyhelminthes are a phylum of relatively simple soft-bodied invertebrate animals
  • They are the largest phylum of acoelomates and are found in marine,freshwater and even in some damp terrestrial environments
  • Movement in some flatworms is controlled by longitudinal,circular and oblique layers of muscle
  • Flatworms anterior end helps in moving towards their food while the posterior end ensures that these organisms walk away from irritants

Why is it important that we understand and are able to use the metric system?
Artyom0805 [142]
The metric system is a system of weights and measures that was first applied in 1795 in France. Experts everywhere the world use it as the international standard to evidently communicate data. The significance are the following:

• SIMPLICITY which is the metric system is much simple than the english system because it uses a standard conversion influence for all units. 

• FAMILIARITY which is almost every nation excluding the united states has accepted the metric system as its official system of weight and measures. 

• UNIFORMITY which is scientists use the metric system so all experiments are conducted using the same weights and measures. 

• HISTORY which is the general session on weights and measures formally chosen six metric units to be used as international standards in 1954 and in 1960 and the meter was formally distinct established on the wavelength of light from krypton atoms.

• TYPES which is the metric system use meters for space, grams for mass, liters for volume and candelas for light.
