The currently used binomial nomenclature was developed by _____. Ray Linnaeus Aristotle

Answers

Linnaeus. Carolus Linnnaeus is a Swedish naturalist whose lasting achievement is binomial nomenclature; it is a system of naming and classifying plants and animals according to genus and species.

The currently used binomial nomenclature was developed by Carl Linnaeus.

Carl Linnaeus, a Swedish botanist, physician, and zoologist, is credited with developing the modern system of binomial nomenclature. He introduced this system in his book "Species Plantarum" published in 1753. In binomial nomenclature, each species is given a unique two-part name consisting of the genus name followed by the species name. For example, humans are known as Homo sapiens, where "Homo" is the genus and "sapiens" is the species.

Linnaeus' system of classification revolutionized the way organisms were named and organized. Before his work, organisms were given long, descriptive Latin names that were difficult to remember and often varied between regions. Linnaeus' binomial nomenclature provided a standardized and systematic way to name and categorize living organisms, making it easier for scientists to communicate about species and study biodiversity.

This naming system also reflects the hierarchical nature of biological classification, with species being grouped into genera, genera into families, families into orders, and so on. It has become the universally accepted method for naming and categorizing living organisms and remains an essential tool in modern biology and taxonomy.

When a gas is dissolved in a liquid, the gas dissolves faster if the liquid is?

Answers

When a liquid's temperature is higher than that of a gas. Under pressure, the solubility of a gas in a liquid happens more quickly. The solubility of a gas in a liquid changes the rate of dissolution.

What happens when a gas dissolves in a liquid?

Liquids and gases combine to generate solutions. As a result, the system achieves equilibrium, with some of the gas molecules dissolving in the liquid and the remaining ones remaining in the gaseousphase above the liquid.

The solubility, which depends on gas pressure, is a measurement of the concentration of dissolved gas particles in the liquid.

When the temperature of a liquid is higher than that of a gas. A gas dissolves more quickly in a liquid when it is under pressure. The rate of dissolution varies depending on how soluble a gas is in a liquid.

Thus, When a gas is dissolved in a liquid, the gas dissolves faster if the liquid is increased or decreased.

Answers

Answer:

inference

Explanation:

An inference refers to the deduction of a reasonable conclusion from an experiment. An inference is drawn based on a logical premise.  

The researcher in this study , reaching to such an inference must have observed and noted the fungi growth with the application of water for several days thereby controlling other variables (growth factor) . Since his/her finding is based on observation and research, this statement "water has increased the growth of fungi" can be considered as an inference.
if you're talking about the experiment; conclusion.
but if you're referring to the fungi; bacteria.

Explanation:

In populations of animals that defend an area for their own exclusive use or in plants that compete intensively for belowground resources such as water or nutrients, the spatial distribution of individuals is usually ____(A) random.
(B) uniform.
(C) clumped.
(D) homogenous.

Answers

Answer:

(B) uniform

Explanation:

According to my research on spatial distribution, I can say that based on the information provided within the question the spatial distribution of individuals is usually uniform. This is usually caused by plants that all receive their nutrients from the same location. Sometime in cases of wind dispersing plant seeds the spatial distribution is uniform but at unpredictable distances.

Identify the values of x and y that would make the following expression represent a real number.(4 + 5i)(x + yi)

A. x = 4, y = 5
B. x = –4, y = 0
C. x = 4, y = –5
D. x = 0, y = 5

Answers

I think the correct answer from the choices listed above is option C. The values of x and y that would make the expression to represent a real number would be that  x = 4, y = –5. Substituting and simplifying,

(4 + 5i)(4 - 5i)
16 - 20i + 20i - 25i²
16 - 25(-1)
16 +25
41

x = 4, y = -5

Further explanation

This is a problem with complex numbers.

A complex number is a number of the form \boxed{ \ z = x + yi \ } where x and y are both real  numbers.

  • x is considered the real part of the complex  number.
  • y is considered the imaginary part of the complex  number.
  • The real part of a complex number \boxed{ \ z = x + yi \ } is denoted by \boxed{ \ Re(z) \ }.
  • The imaginary part of a complex number is denoted by \boxed{ \ Im(z) \ }.
  • The modulus of a complex number \boxed{ \ z = x + yi \ } is denoted by \boxed{ \ |z| \ } and defined to  be \boxed{ \ |z| = √(x^2 + y^2) \ }
  • Remember this \boxed{ \ i^2 = (√(-1))^2 = -1 \ }

For example, \boxed{ \ z = 3 - 4i \ }

  • Re(z) = 3
  • Im(z) = -4
  • The modulus \boxed{ \ |z| = √(3^2 + (-4)^2) = 5 \ }  

Let's look at the key problem.

We must identify the values of x and y that would make the following expression represent a real number.

\boxed{ \ = (4 + 5i)(x + yi) \ }

\boxed{ \ = 4(x + yi) + 5i(x + yi) \ }

\boxed{ \ = 4x + 4yi + 5xi + 5yi^2 \ }

\boxed{ \ = 4x + 4yi + 5xi - 5y \ }

At this point, 4yi and 5xi must be of equal value and marked opposite, so that the expression represents real numbers.

\boxed{ \ 4y = - 5x \ }

Become a fraction, i.e.,

\boxed{ \ (x)/(y) = (-4)/(5) \ or (x)/(y) = (4)/(-5) \ }

From the options, the answer is C.

\boxed{ \ x = 4, y = -5 \ }

- - - - - - -

Let's check back to expression.

\boxed{ \ = (4 + 5i)(x + yi) \ }

\boxed{ \ = 4x + 4yi + 5xi - 5y \ }

x = 4 dan y = - 5 ⇒ \boxed{ \ = 4(4) + 4(-5)i + 5(4)i - 5(-5) \ }

\boxed{ \ = 16 + -20i + 20i + 25 \ }

\boxed{ \ = 16 + 25 \ }

\boxed{ \ = 16 + 25 \ }

Thus the expression represent a real number of 41.
