Sound quality can be divided
iris [78.8K]
Sound quality can be divided into amplitude, timbre and pitch. If there’s an impedance mismatch between your two devices connected to the single output, you could have a large mismatch between the levels arriving at each device. If the difference is large enough, one device may have distorted or inaudible audio.

To avoid this, you should ensure that both devices connected to the split signal are similar - such as 2 pairs of headphones, 2 recorder inputs, and so on. When you place 2 devices with wildly differing load impedances on a splitter is when you’ll encounter problems - such as headphones on one split and a guitar amp input on the other.

To get around this, you can use either a distribution amplifier (D.A.) or a transformer balanced/isolated splitter - which will work over a larger range of load impedances, typically. Depends on the quality of the splitter and the exact signal path. If you’re using the splitter to hook two things into one input, and you’re using quality connectors, you probably won’t lose much quality. There can be an increase in impedance of the cable due to the imperfect continuity of the physical connection, however with unbalanced line-level signals, impedance at both ends of the chain tends to be orders of magnitude higher than the connection will create, so one split will be barely noticeable. So too, the noise increase from the additional length of cable.

Now, one source into two inputs, that will by basic math and physics result in a 3dB drop in signal strength, which will reduce SNR by about that much. By splitting the signal path between two inputs of equal impedance, half of the wattage is being consumed by one input and half by the other (the equation changes if the inputs have significantly different impedances). So each input gets half the wattage produced by the source to drive the signal on the input cable, and in decibel terms a halving of power is a 3dB reduction. Significant, until you just turn the gain back up. The “noise floor” will be raised by however much noise is inherent in the signal path between the split and the output of the gain stage; for pro audio this is usually infinitesimal, but consumer audio can have some really noisy electronics, both for lower cost and because you’re not expected to be “re-amping” signals several times between the source and output.

In three to five sentences, describe the advantages and disadvantages of these maps in modeling mitosis.
Nina [5.8K]

Modelling refers to using a diagrammatic representation to present a particular event or biological activity.

The two maps shown are very good for representing/modelling mitosis.

Advantages

  • They clearly lists the various steps involved in mitosis and as well included the process of cell division starting from the interphase stage (for the second diagram).
  • The M phase was also clearly explained in the first diagram.

Disadvantages

  • The first pictorial diagram had to labelling to depict the name of each particular phase and makes understanding difficult.
  • The second diagram fails to show pictorial representation of what could have exactly happened in each stage in the process of cell division.

Refer to the tree of life shown above. What can you conclude about fungi?
svp [43]

Answer:

Fungi are more closely related to animals than they are to plants.

Explanation:

A fungus (plural: fungi) is a kind of living organism: yeasts, moulds and mushrooms are types of fungi. The fungi are a separate kingdom of living things, different from animals and plants. Fungi have cells with nuclei. Their cell walls contain chitin, unlike the cell walls of plants, which contain cellulose.

In a study published in the journal Nature, scientists studied eight ponds in Florida: four that were populated by a species of
Reika [66]

Answer:

Explanation:

The rate of pollination in the field (near the pond with no fish) will decrease exponentially. Because, as the fish population is removed from that ecosystem, the population of dragonflies and larva increases without check because, fish feeds on the dragonflies larva and kept there population in check. Due to this, the population of bees and other pollinators population decline becuase, they are major food source of dragonflies.

Honeybees are the keystone species because it's absence will lead to major changes in the ecosystem.
