<h2>Fixation</h2>
Nitrogen in its gaseous form (N2) can’t be used by most living things. It has to be converted or ‘fixed’ to a more usable form through a process called fixation. There are three ways nitrogen can be fixed to be useful for living things:
<h3>Biologically: </h3>
Nitrogen gas (N2) diffuses into the soil from the atmosphere, and species of bacteria convert this nitrogen to ammonium ions (NH4+), which can be used by plants. Legumes (such as clover and lupins) are often grown by farmers because they have nodules on their roots that contain nitrogen-fixing bacteria.
<h3>Through lightning: </h3>
Lightning converts atmospheric nitrogen into ammonia and nitrate (NO3) that enter soil with rainfall.
Answer:
B. All of the fish, bacteria, and mammals that live in a lake
Explanation:
In terms of biology an individual make population, population makes a species and interaction between different species makes community. Interaction of living and non-living things make an ecosystem.
Community involves interaction between all the living organisms present in a given environment. Hence, interaction between fish, bacteria, and mammals that live in a lake is a community.
Hence, the correct answer is "B. All of the fish, bacteria, and mammals that live in a lake".
Answer:
D
Explanation:
im going to guess its a cause think of it this way its like family in a way if raccoons and red pandas are a more common ancestor than they might have been family along the lines of history somewhere if its not a than d i hop this helps and id pick d it sounds more frequent
Answer:
C) hematocrit is highest
Explanation:
The viscosity is the property of the fluid substance related to the flow of the resistance. The flow of the resistance increases when the amount of content in the fluid increases.
The flowing blood contains the water and the other components like the cells and proteins therefore it also exhibit the viscosity.
The viscosity in blood happens when the cells and molecules interact with each other therefore measure of these components indicated about the viscosity of the blood.
The hematocrit is the ratio of the proportion of the red blood cells present in the blood to the total volume of the blood.
The viscosity of blood, therefore, increases when the hematocrit is high and decrease when the hematocrit component is low.
Thus, Option-C is the correct answer.
