Answer:

Off-pump coronary artery bypass

Explanation:

In this heart bypass surgery a vein or artery from another part of the body is taken and used as a graft to replace the blocked coronary artery. The benefit of this type of surgery is that there is negligible chances of rejection of the graft because the graft has been taken from the same body. A surgical cut is made inside leg, between the ankle and groin and one end of the graft is attached to coronary artery whereas the other end to the opening of aorta.

Radial artery of wrist is also common graft in heart bypass surgery.

xxTIMURxx [149]

The oldest true fossils are trace fossils called Stromatolites found in Australia, and dated between 3.5 to 3.3 billion years old.

Raphael Baumgartner and their team have finally uncovered evidence of organic matter in the ancient rock formations known as stromatolites found at the Dresser Formation fossil site in the Pilbara region of Western Australia. They detail their findings in a new article published in the journal Geology.

With a variety of methods, including scanning electron microscopy, scanning transmission electron microscopy, energy dispersive X-ray spectroscopy, Raman spectroscopy, nano-scale secondary ion mass spectrometry, and stable carbon isotope analysis, the researchers examined the samples in thin slices.

According to the team's analyses, pyrite, a mineral with many tiny pores, makes up the majority of the stromatolites. Additionally, the pyrite contains nitrogen-bearing organic material and strands and filaments of organic material that closely resemble the remains of microbial biofilm colonies.

Which is a phenomenon that can result from directional selection? a. There is an increase in the number of different breeds of d
anzhelika [568]

Answer:

B) There is an increase in the number of giraffes with long necks in areas of Africa where low-growing trees have died

Explanation:

The directional selection is one of the ways of the natural selection in which the natural selection selects or favours the most extreme trait of the species and the extreme trait show higher fitness than the normal or average trait.

In the given question, the case of Giraffe necks shows directional selection as the normal length of the neck is not favoured by the environment but the extreme trait that is long neck is favoured by the environment and the selection shifted to that level.

Thus, Option-B is the correct answer.
