In the formation of potassium nitride, zero valence electrons are transferred from nitrogen to potassium.
A valence electron is an electron in the outer shell of an atom that can participate in the formation of a chemical bond if the outer shell is not closed. A shared pair forms in a single covalent bond, with each atom contributing one valence electron.
From potassium to nitrogen, electrons are transferred.
The outermost cells contain valence electrons, which are capable of forming chemical bonds.
The formula is:
6K + N₂ ⇒ 2K₃N
K = K⁺ + e⁻
NO₃ + e⁻ = NO³⁻
Potassium transports electrons to nitrogen.
As a result, nitrogen transfers no electrons (zero) to potassium.

Explain how a. temperature and b. light intensity 0 affect the rate of transpiration.
Answer:
Explanation:
Transpiration can be regarded as process involving water movement through a plant, it involves evaporation from aerial parts. These aerial part could be such leaves, stems or flowers.
A)Temperature
During the day period when the weather is hot there would be increase in evaporation of water from the leaves of plants, due to this transpiration is increased
B)Light intensity
When there is bright light, when the light intensity heat the plants, the stomata would be opened so that carbon dioxide is supplied for photosynthesis, and more water would be evaporated out through the leaves of the plant, then transpiration increase
In three to five sentences, construct an argument that shows why lichens are necessary to establish a new ecosystem after an extreme disturbance.
I would really appreciate it if someone o two people would help me out on this one
Answer: Lichens affect every species in the ecosystem, in 2013 Russia had a dramatic lichen die off which caused 61,000, 20% of the entire reindeer population to die from starvation. And with fewer deers, the bears and wolves also suffered from the loss of lichens and if it takes a long time for lichens to grow back in an ecosystem, animal declines may take years if ever to be corrected. Lichens serve as a basis for several food chains, especially in artic communities.
The argument which shows why lichens are necessary to establish a new ecosystem is as follows;
Lichens are known to enable algae to live all over the world in many different climates.
On this note, lichens also provide a means to convert carbon dioxide in the atmosphere through photosynthesis into oxygen, a process required by all to survive.
Additionally, lichens provide us with valuable information about the environment around us.
On this basis, lichens are important for establishing a new ecosystem after an extreme disturbance.

Mitosis vs Meiosis, someone help me with this, ill give brainiest.
♡ hi there!! i tried to go back to my notes, but i couldn't find anything. but here if an explanation i found. ♡
different: mitosis consists of one stage whereas meiosis consists of two stages. mitosis produces diploid cells (46 chromosomes) whereas meiosis produces haploid cells (23 chromosomes). mitosis produces two identical daughter cells whereas meiosis produces four genetically different daughter cells.
similar: both involve cell division, both the processes occur in the M-phase of the cell cycle. In both cycles, the stages are common – metaphase, anaphase, telophase and prophase. synthesis of DNA occurs in both.

Red tides are caused by red dinoflagellates (Gonyaulax) that multiply rapidly.
I hope it's helpful!
Answer:
Algal bloom refers to vigorous growth of algae or blue-green algae in water, due to enrichment of water body with minerals nutrients coming from fields, resulting in discoloration of the water body.

The place where the new volcanoes are less likely to be seen is mid-ocean ridge. The correct option is A.
What is volcano?A volcano is a crack in the crust of a planet, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber beneath the surface.
Volcanoes are most commonly found where tectonic plates are diverging or converging on Earth, and the majority are found underwater.
Although Australia is the only continent with no active volcanoes, it does have one of the world's largest extinct volcanoes, the Tweed Volcano.
Volcanism is directly related to plate tectonics theory. Volcanoes are only found at specific types of plate boundaries, and only rarely in the middle of ocean plates.
Thus, the correct option is A.

The relationship that occurs between an orchid attached on a narra tree could be
classified as Commensalism and Parasitism. True or false?
Answer:
Yes, it's True
Explanation:
A parasitic relationship helps one of the species involved in the relationship, but harms the other organism in the process of it growing. It is a symbiotic relationship and would be classified as Commensalism. Most of the orchids are epiphytes, so they tend to grow on other plants. hope you understand. Fighting!
The relationship that occurs between an orchid attached on a narra tree could be classified as Commensalism. Thus, the given statement is true.
What is Commensalism?Commensalism is a long-term biological interaction or symbiosis in which the members of one species gain benefits which help them in survival while those of the other species are neither benefitted nor are harmed from the association.
In contrast with mutualism, in which both the organisms benefit from each other and amensalism, where one species is harmed while the other species is unaffected and that of parasitism, where one species is harmed and the other species benefitted.
