It was discovered by Alexander Fleming in the 1920's that Penicillium notatum produced a substance, know as penicillin, which ha

d antibiotic properties. Many would consider this to be one of the greatest and most important medical discoveries of all time. Penicillium notatum is what type of organism?

Answer:

a bacterium

Explanation:

<em>Penicillium nonatum is a type of </em><em>bacterium</em><em>.</em>

<u>Bacteria are prokaryotic, microscopic organisms that are capable of adopting different lifestyles based on their mode of nutrition. While some are capable of manufacturing their foods via photosynthesis/chemosynthesis, some are saprophytic in nature while others lives as parasites on living organisms.</u>

Those that lives as parasites are often capable of causing diseases and are therefore called pathogens.

Penicillium nonatum is capable of producing a substance that has the capacity to inhibit the growth of another bacteria. Substances that are capable of inhibiting or killing bacteria are generally known as antibiotics.

HELP ASAP I WILL GIVE BRAINLIST
adelina 88 [10]

Answer:

1) CO₂

2) 0.2551 g

Explanation:

The balanced reactions are:

CaCO₃ + 2HCl → CaCl₂ + H₂O + CO₂

MgCO₃ + 2HCl → MgCl₂ + H₂O + CO₂

1) The gas produced is CO₂.

2) Calculate mass of CaCO₃:

(0.5236 g) (0.4230) = 0.2215 g CaCO₃

Convert to moles:

(0.2215 g CaCO₃) (1 mol / 100.1 g) = 0.002213 mol CaCO₃

Find moles of CaCO₃:

(0.002213 mol CaCO₃) (1 mol CO₂ / mol CaCO₃) = 0.002213 mol CO₂

Convert to mass:

(0.002213 mol CO₂) (44.01 g / mol) = 0.09738 g CO₂

Calculate mass of MgCO₃:

(0.5236 g) (0.5770) = 0.3021 g MgCO₃

Convert to moles:

(0.3021 g MgCO₃) (1 mol / 84.31 g) = 0.003583 mol MgCO₃

Find moles of MgCO₃:

(0.003583 mol MgCO₃) (1 mol CO₂ / mol MgCO₃) = 0.003583 mol CO₂

Convert to mass:

(0.003583 mol CO₂) (44.01 g / mol) = 0.1577 g CO₂

Total mass of CO₂:

0.09738 g CO₂ + 0.1577 g CO₂ = 0.2551 g CO₂

Translate the word phrase into an algebraic equation: the quotient of 24 and 2 is equal to 12.
igor_vitrenko [27]

Answer:

24/2 = 12

Explanation:

(I'm pretty sure this isn't a Biology question, but I'll answer this because I'm nice.)

To translate English into algebriac equations, we have to understand what the symbols in algebra mean. Here are some we should know:

= : "equal to", "is", "equivalent to", etc.

> : "greater than"

< : "less than"

>= : "greater than or equal to", "at least"

<= : "less than or equal to", "at most"

We also have to know basic math operations:

a + b : "a added to b", "a plus b", "a combined with b", "a more than b", etc.

a - b : "a minus b", "b less than a", "b subtracted from a", etc.

a * b : "a multiplied by b", "a times b", "the product of a and b", etc.

a / b : "the quotient of a and b", "a divided by b", etc.

There are MUCH MORE examples of this, yet it becomes second-nature to change English sentences into algebra.

So, let's tackle the question. Sadly, it's pretty simple, so I won't really go in depth here. Since the quotient of a and b is a/b, the quotient of 24 and 2 is 24/2. We can also say that "is equal to 12" is "= 12". So,

24/2 = 12.

Oduvanchick [21]

Answer:

Electroencephalogram

Explanation:

In the cerebral cortex, cell bodies (soma) and dendrites produce the synaptic potentials that create an electrical activity that can be measured by electrodes placed on the scalp resulting in an <u>Electroencephalogram</u>.

a test or record of brain activity produced by electroencephalography.

Electroencephalography is an electrophysiological monitoring method to test or record brain activity.
