The correct answer is:
Grow a legume crop to support the development of root nodule
The best way that a farmer could increase the amount of nitrogen in his fields without adding synthetic fertilizer is to grow a legume crop to support the development of root nodules. This is because legumes have a symbiotic relationship with bacteria found in the soil.
Explanation:
Legumes use nitrogen fixing bacteria, specifically symbiotic rhizobia bacteria, within their root nodules to counter the limitation.The plant root cells convert sugar into organic acids which then supply to the rhizobia in exchange, hence a symbiotic relationship between rhizobia and the legumes.
Answer:
undifferentiated; blood
Explanation:
Hematopoietic stem cells are undifferentiated cells that develop into blood cells.
Answer:
The answer is 306 m/s^2
Explanation:
F = m*a
We can rearrange this formula to get a = F / m.
The SI unit for mass is kilograms (kg).
The SI unit for acceleration is m/s^2.
There are 1000 grams in a kilogram.
7.20 g = 0.00720 kg
Force (2.20 N) / 0.00720 kg = 305.56 m/s^2
Accounting for Sig Figs, the answer is 306 m/s^2.
Gee, that's one fast bullet.
Streptococcus infection carries all the symptoms mentioned.
<h3><u>Explanation</u>:</h3>
<em>Streptococcus pneumoniae</em> and <em>Diplococcus pneumoniae</em> are the organisms that gram positive bacteria. These bacteria enters the respiratory system from droplet method propagation which is through aerosol or water droplet inhalation which are infected with these bacteria. These bacteria leads to the severe antigen antibody reaction inside lungs which leads to high rate of mucous secretion. This leads to formation of pneumonia.
These bacteria are mainly seen in tropical countries with warm climate and humid environment. These bacteria doesn't spread through contagious methods like touching. But the protection must be taken as these patients cough can contain lakhs of these bacteria which are enough to infect a healthy individual.
