Answer:

The correct answer is D) They convert elemental nitrogen into ammonia and nitrates for uptake by the plants.

Explanation:

Plants and crops are not able to use elemental nitrogen. Most of the microorganisms that live around the roots of the plant helps in converting the elemental nitrogen into ammonia and nitrate so that plants can use and uptake the nitrogen from soil.

These bacteria are called nitrogen-fixing bacteria. They invade the roots of plants and crops and form root nodules where they grow and convert nitrogen into ammonia and nitrate which is taken by plants. Some nitrogen-fixing bacteria are <em>Rhizobium , Nostoc, Azotobacter, Beijerinckia,</em> etc. So the right answer is D.

soldier1979 [14.2K]

Answer:

OH, H2O2 and O−2

Explanation:

Reactive oxygen species (ROS) can be defined as highly reactive chemical compounds formed from molecular oxygen (O2). ROS are generated as a normal product of cellular metabolism, and also as a response to different environmental/internal cellular stimuli (e.g., cytokines, xenobiotics, pathogenic invasion). For example, hydroxyl radicals (·OH) are a type of ROS generated in the mitochondria which are capable of inducing oxidative stress in different cells and also trigger chronic inflammation. Moreover, hydrogen peroxide (H2O2) molecules represent another type of ROS which are produced during the stereoselective deamination of amino acids, i.e., the building blocks of proteins. These molecules (H2O2) exhibit toxic effects on the cell (e.g., DNA damage). Finally, singlet oxygen (1O2) is an excited state of molecular oxygen (O2) that is generated during photosynthesis in the photosystem II (PSII) of chloroplasts.

Leno4ka [110]

Damage to the nervous system is causing Kai to have pain and numbness.  

<h3><u>Explanation:</u></h3>

Kai injured his knee. We know that the posterior surface of the knee has the quadrangular fossa which is guarded by the tendons of hamstrings anteriorly and by the two heads of gastrognemus muscle below. There are several nerves running down the leg through this region.

Any trauma to this fossa can cause these nerves to get damaged. Thus it can lead to numbness of lower limb. Proper physiotherapy is required to recover as soon as possible. Else that can even lead to paralysis of lower limb.

What is an example of phototropism?
a_sh-v [17]

Answer:

Explanation:

Positive phototropism is growth toward a light source, and negative phototropism is growth away from a light source. ... Sunflowers are a great example of positive phototropism, because not only do their stems curve toward the light but their flowers turn to face the sunlight as well.

Do you think brianna's blood pressure is normal? explain your answer.
Paha777 [63]
In the case of newborn twins, Brianna blood pressure is not normal but rather is low at 85/55 compared to Christophers 110/70. She has inadequate pumping of blood from her heart to the body while her breathing is rapid and deep in trying to get oxygen. It is because of inadequate pumping of blood that may lead to issues with her lungs.
Before she was diagnosed with retractile sclerosing mesenteritis, her eyes and lips were blue while her blood pressure could not read. After two weeks o her surgery, her blood pressure dropped severely low and had a breathing tube and 13 IV lines. She had caused lung damage caused by aspirations of contents in the stomach.
By third week she was in a coma but regained her physical skills and her consciousness after her last surgery (fourth).
