QUESTION:-
What is the maximum number of electrons that can be placed in the first shell/energy level?
A. 1
B. 8
C. 2
D. 18
Answer:
C. 2
The first shell, closest to the nucleus and with the lowest-energy electrons, is shell 1. This first shell has only one subshell (labeled 1s) and can hold a maximum of 2 electrons
Photosynthesis is a process when the plants is absorbing sunlight to use the sunlight to make energy for them.
Photosynthesis equation :
6CO2 + 6H2O -> C6H12O6 + 6O2
Carbon dioxide + Water -> Sugar + oxygen
Answer:
Metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock. The parent rock can be either sedimentary, igneous, or even another metamorphic rock.
Answer:
<em>The fungus can be transmitted through contact and the fungus is deadly to bats.</em>
Explanation:
David Blehert was a scientist who had received a PhD in the field of bacteriology.
David Blehert's hypothesis provided evidence that white-nose fungi were capable of causing death in bats. Even exposure of healthy bats to the bats which were infected with white-nose fungi caused illness and even death of the previously healthy bats.
David Blehert's hypothesis was also supported by other people who conducted the experiments and hence, was considered to be true.
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.
<u>Example:</u>
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.
