Answer:

stages of the nitrogen cycle

1. Nitrogen-fixation

Legume plants such as peas, beans and clover contain nitrogen-fixing bacteria. These bacteria live in swellings in the plant roots called nodules. Nitrogen-fixing bacteria convert nitrogen gas from air into a form that plants can use to make proteins.

Free-living nitrogen-fixing bacteria are also found in the soil. When they die the nitrogen they have fixed into their biomass is converted into ammonium.

2. Feeding

Animals consume plant protein, digest it using specific enzymes and absorb the free amino acids.

3. Production of nitrogenous waste products

Animals cannot store excess protein in their bodies. They break it down and turn it into waste products and excrete them from their bodies.

4. Decomposition

Decomposers (some free-living bacteria and fungi) break down animal and plant proteins (from dead organisms) and nitrogenous waste products to release energy. As a result of decomposition nitrogen is released into the soil in the form of ammonium.

5. Nitrification

A group of free-living soil bacteria called nitrifying bacteria convert ammonium into nitrates in order to obtain energy.

6. Uptake of nitrates

Non-legume plants absorb nitrates from the soil into their roots and use the nitrates to produce their proteins.

7. Denitrification

This is when bacteria in the soil convert the nitrate back into nitrogen gas which then gets released back into the atmosphere.

Since most personal watercraft (pwc) do not have brakes, what must be done in order to avoid an obstacle?

Alex_Xolod [135]

With Personal Watercraft having no brakes, the best thing to do in avoiding obstacles is to take caution and slow down while operating the Personal Watercraft boat but when obstacles are ahead and you need to use methods, it is best to apply throttle and after that, steer quickly.

Draw and label the parts of the eye. State the function of any five parts of the eye.

Sidana [21]

Answer:

The labeled drawing is attached; I just grabbed an image off of the internet. You can do this by hand by just copying what's in your textbook or other reference materials. Let me define five main parts:

Retina. This is a thin layer of tissue on the back of the eye that receives the signals of light and transfers them to the brain so you can understand them as color and sight.
Cornea. This is the front part, a reflective layer that "refracts" light. What this means is that light doesn't go directly through it, but its path is almost deflected a little.
Sclera. This is the part that looks white from the front. It's a protein covering to your eye, and it's very close to the cornea.
Iris. This is the actually colored part of your eye. If you have hazel or blue eyes, the iris is that portion of the eye. It allows differing amounts of light in.
Pupil. This is the black part of the eye. It's a hole that looks black because of all the light coming through and being absorbed.

50. The flow chart below shows how a metamorphic rock can change into a

max2010maxim [7]

Answer:

The process that would be the correct label to replace the question mark in this question is:

B) Deposition

Explanation:

Deposition takes place after erosion of sedimentary rock. At this stage, the eroded sedimentary rocks build up under high pressure heat, wind, ice, water, and other natural forces to originate the rock formation cycle once again. Naturally, after deposition, the igneous rocks, which have then layered up sedimentary rocks to become metamorphic rocks.

What part of DNA gives instructions to a cell for expressing traits?

Verdich [7]

Answer: Transcription

Explanation: Genes consist of sequences of molecules, called bases, in your DNA. During transcription, an enzyme called RNA polymerase “reads” your genes and copies the information onto molecules of messenger RNA.

Which statement best explains the impact of favorable oceanic conditions on the Geosphere?

GREYUIT [131]

Answer:

The best answer is "Ocean waves add more sand to beaches"

Explanation:

based on statement above, the oceanic conditions are changes in ocean parameters (temperature and movement) and substances which contain in oceans (salinity, nutrient availability, oxygen and carbon dioxide level, etc).

Geosphere is a part of the earth that included the earth's interior, landform, rocks, and mineral. There are lithosphere, atmosphere, hydrosphere, biosphere and, anthroposphere.

on the answer choice, the ocean wave is the example of the oceanic condition which has changed in movement. and the beach is an example of the lithosphere.
