Which of the following does NOT contribute to genetic variation among plants?
egoroff_w [7]

Answer:

The correct answer will be option-A.

Explanation:

Genetic variation is the difference in the DNA sequences of individuals in a population. Genetic recombination is the main reason for the diversity of organism on earth.

The genetic variation takes place during gamete formation by recombination of DNA sequences which takes place during prophase of meiosis I.

Since genetic variation involves changes in the coding segments of the DNA called genes which leads to mutations, therefore, flowering time does not influence the genetic variation and option-A is the correct answer

The nurse places the stethoscope on the 3rd intercostal space at the left sternal border. Which area is the nurse auscultating f
miv72 [106K]

The nurses auscultated for heart sounds in the area of Erb point.

The fifth point of auscultation for the heart test, known as "Erb's point," which is occasionally given to the eminent German neurologist Wilhelm Heinrich Erb (1840–1921) without any supporting documentation, is positioned in the third intercostal gap near the sternum. At the third intercostal gap and the left lower sternal border is the auscultation location for heart sounds and heart murmurs known as Erb's point.

The spinal accessory nerve in the posterior nerve triangle is located at Erb's point (also known as the great auricular nerve) at the location where it enters the trapezius muscle. At the end of expiration, the third intercostal gap on the left (Erb's point) is often the ideal place to detect the murmur of aortic regurgitation because it is quiet, high-pitched, early diastolic and decrescendo.
