Answer:
5 lumbar vertebrae
Explanation:
As you can see in the image I annexed, a typical adult skeleton has 5 lumbar vertebrae (colored in red), they are cylindrical bones located between the rib cage and the pelvis, they are the largest segments of the vertebral column. These vertebrae carry all of the upper body’s weight, they protect the spinal cord and nerves in the vertebral canal, they also provide flexibility and movement to the trunk region.
I hope you find this information useful and interesting! Good luck!
Answer:
Weeds that are not resistant to glyphosphate and crops that are resistant.
Explanation:
The best combination that is looked for by all agricultural farms are Weeds that are not resistant to glyphosphate and crops that are resistant.
This is because this combination allows the farmers to easily spray large quantities of glyphosphate over the fields, and doing so killing all the weeds without harming the crops in the field. Making it a win-win for the farmers.
The root nodules of leguminous plants houses nitrogen-fixing bacteria called Rhizobia. Rhizobia has a symbiotic relationship with leguminous plants that allows both to benefit from each other.
By binding to hydrogen, the Rhizobia bacterium is able to convert or fix nitrogen gas into ammonia , a form that the plant can use. Likewise, the legume plant provides the rhizobia bacterium with carbohydrate which the rhizobia depends on for energy. It is important to note that the carbohydrate sent to the nodules for the rhizobia is also what is used as a source of hydrogen to help the bacterium convert nitrogen to ammonia.
A molecular clock is a method used by researchers that uses mutation rates in DNA to estimate the length of time that two species have been evolving independently. This provides evidence of evolutionary descent because it can link to common ancestors.
