After nitrogen becomes part of the lithosphere, the next change the nitrogen will under go is it will be:-
A. used as a nutrient by plants
B. fix by bacteria in the soil
C. absorbed into the atmosphere by lightning
Answer:-B. fix by bacteria in the soil
Explanation:-These bacteria are known as nitrogen-fixing bacteria. These nitrogen-fixing bacteria convert nitrogen in the soil to ammonia. Ammonia can be taken up by plants.The illustration below represents____,
which is responsible for genetic diversity.
Answer: Crossing over
Explanation: This is what a crossing over gene looks like it starts together and separates here is evidence below ⬇️
The illustration below represents the crossing over stage in meiotic cell division which is responsible for the genetic diversity in organisms. Thus, the correct option is B.
What is Crossing over?Meiosis is the type of cell division during which the chromosome number in the daughter cells become half of that present in the parent cells from which they are produced. From one parent cell four daughter cells are formed in meiosis.
Chromosomes forms the chromatids in the cell which form tetravalent with the non-sister chromatids of the homologous chromosomes. This stage is called crossing over where the genetic material present in each of the chromatids are exchanged which results into genetic diversity in a species. After the crossing over stage, the chromatids separate from each other and goes to different daughter cells.
Therefore, the correct option is B.

This is called . ________ This makes the liquid become
kinetic energy is needed by the molecules in order to escape from the surface.
All the water molecules in the liquid are moving randomly due to the presence of some energy in it. Some of the molecules have more kinetic energy due to absorption of heat energy from the surrounding environment.
Due to high kinetic energy, these molecules move enough to escape the surface of the liquid. This is called boiling point. This makes the liquid become gas so we can conclude that kinetic energy is needed by the molecules in order to escape from the surface.

In the area illustrated, what process is evident over time?
In the area illustrated in the image attached, the biological process which is evident over time is: ecological succession.
Ecology can be defined as the scientific study of the relationship existing between living organisms such as plants and animals with respect to their physical and biological environment (abiotic factor).
In Ecology, ecological succession refers to a process through which the structure of an ecological (biological) community evolves or changes over time.
Generally, there are three (3) main types of ecological succession and these include:
Primary successionSecondary successionCyclic successionFrom the ecological (biological) community illustrated in the image attached, we can deduce that there is an evolution (change) in the species of plants growing over time. This ranges from weeds during the first visit to pine and oak trees during the seventh visit.

In an ecosystem, a deer consumes grass. What percentage of energy will the deer acquire from the grass? 0. 1% 1% 10% 100%.
In an ecosystem, the energy is transferred between the organisms participating in the food webs from producers and consumers.
The percentage of energy transferred to the deer after feeding on the grass is 10%.
The 10% law of the energy states that:
1. The food chain at each trophic level passes or transmits only 10% of the energy and 90% of the energy is lost as heat.
2. The amount of energy at each trophic level decreases, such that the producers if consuming the 100 J of energy, the deers or primary consumers at the first trophic level will have only 10% of the energy.
Thus, the deer will possess only 10% of the energy at each trophic level, following the 10% law.
The correct answer is Option C.
