Sabouraud's agar restricts the growth of bacteria and is an example of a medium, whereas Mannitol salt agar can determine which

krok68 [10]

Given what we know, we can confirm that the fact that Mannitol salt agar can determine which species of Staphylococcus is present makes it an example of a selective differential medium.

<h3>What is a selective differential medium?</h3>

This type of medium is very similar to that of a differential medium in that it also allows more than one type of microbe to grow.
It also allows the user to continue to distinguish between the microbe colonies based on biochemical differences.
However, in contrast to that of a basic differential medium, this differential medium is also selective in that it controls which type of microbe specifically is allowed to grow.

Therefore, we can confirm that since Mannitol salt agar can determine which species of Staphylococcus is present, it can be considered a differential selective medium because it allows multiple microbes to grow while controlling which types are allowed to grow.

The taxon species may be defined by reproductive isolation and _____.

ivann1987 [24]

<h3>Answer;</h3>

Morphology

The taxon species may be defined by reproductive isolation and morphology 

<h3>Explanation;</h3>

A taxon is a group of one or more populations of an organism.
Morphology is the form or the appearance of a particular organism, while reproductive isolation is the separation of organisms by some type of barrier.
Reproductive isolation is a type of mechanisms that prevent two or more organisms or populations from exchanging genes through reproduction. This occurs when two organisms or species are separated for too long such that they can no longer reproduce with each other due to different adaptation and changes in the environment.
Morphology and reproduction isolation may be defining characteristics of taxon of species.

Andrew [12]

Answer:

Renewable energy: solar radiation

Farm example: Farm located in Heggelbach, Germany

Explanation:

Solar radiation is one of the most used types of renewable energy. It proportionates light during the whole day (even during the cloudy days), which is received by solar photovoltaic panels. These photovoltaic panels are formed by solar cells that turn the solar light (photons) into electricity (electrons) through the photoelectrical process. Certain materials are capable of absorbing photons and releasing electrons, generating by this movement, electric current.

Solar energy is being used in many places to avoid using fossil fuels as energy sources and replace them. Specifically, in farms, this energy is used for equipment operation and machinery use.

Even the combination of solar panels and agriculture is taking place in the same land area or parcel. In the same place where solar panels are installed, and under them, vegetables are being grown. The advantage for certain vegetable species is that panels protect from excessive radiation or other adverse climatic conditions.

Example:

In 2018 in Heggelbach - Germany- a five meters structure of solar panels was installed on a farm. Under them, different crops were grown. The production under the photovoltaic system was highly superior to the traditional one. The efficiency of land use increased by 186% per hectare with the agro-photovoltaic system.
