Why might (mostly) boneless creatures, like jellyfish, sea slugs, squid, and octopuses, fare especially well underwater? What is
vagabundo [1.1K]

Answer:

The species that develop in aquatic environments, need to be able to have an adequate locomotion and according to the hydrostatic pressure in the water, which this pressure has the opposite direction to gravity in terrestrial life.

Explanation:

Vertebrates that have a skeleton are accustomed to gravitational forces, and this bone structure is what allows adequate locomotion to perform movements as a function of the force of earth's gravity, in water the force of gravity has no effect, since that the hydrostatic force predominates, which the direction is opposite to the gravitational forces.

Amorphous bodies, with few solid structures, not bony, make them better adapt to movements in water masses that are promoted by hydrostatic forces.

what are some advantages and disadvantages of using permanent slides as opposed to temporary slides to view tiny aquatic animals
nikitadnepr [17]

Answer:

Permanent slides ensures preservation of the body parts of the tiny aquatic animals and also also aids good visualization.Most of the exoskeleton of   these tiny   animals are lost during temporary slides preparation, thus loss of visualization.

Because the animals are transfixed to a point, their body parts can not be moved.

It also saves time, energy and resources spent during observation.

However,because of dehydration during preparation  their natural color may be lost which may affect observation of natural features

A graph with a calibration curve, linear regression and extrapolation was drawn up from your lab results. What were the two type
fiasKO [112]

Answer:

X is the concentration of the substance being measured and Y is the response from the instrument that is being used to measure

Explanation:

A calibration curve is the plot of known concentration of substances where x is the increasing known concentration and Y is the response, typically "absorption" taken from the instrument that is used for measuring. This curve is then used to find out the concentration of the unknown substance by using it's absorbance and comparing it with the calibration curve. For example:

Concentrations and absorbance readings are as follows

0.5mg/mL=10 nm

1.0mg/mL=15nm

1.5mg/mL=20nm

2.0mg/mL=25nm

This data is plotted on a calibration curve. Next we measure the unknown substance the absorption is 20nm. We can suggest that the concentration is 1.5 mg/mL. If there are readings that fall inbetwen values then the formulat to calculate the right concentration would be y = mx + b, where m is the slope and b is the y-intercept.

Linear regression uses the modification of the slope formula y= a + bx to best see how the data of the water samples would fit on the slope of the calibration curve. X is the independent variable , b is the slope of the line and a is the y-intercept.

Extrapolation would be the action of calculating data that are outside the calibration curve,  assuming the trend would continue.
