miss Akunina [59]

Hi, the given question is incomplete, it is missing a diagram, the diagram is given in the attachment below,

Answer:

The correct answer is adaptive evolution.

Explanation:

Based on the given information, it is clear that it best illustrates the phenomenon of adaptive evolution. It is known that different species of finches exhibit an ancestor, which is common, however, all the species have shown adaptation based on the kind of food they are getting within their surroundings.  

The evolutionary modifications that arise by getting adaptive to the specific environment are termed as adaptive evolution. These changes arise due to the phenomenon of natural selection, which further enhances the tendency of reproducing or survivorship after going through some of the challenges presented by the surroundings.

Ivenika [448]

Question: Describe how a single amino acid substitution causes hemoglobin molecules to stick together. Use what you know about the structure of Hb and HbS, the properties of glutamic acid and valine, and how hydrophobicity causes molecules to behave in water.

Answer:

A Single amino acid must be polar to attract, just like water.

Explanation:

Sickle cell is an genetic illness and it is began by a alteration that arises in the beta sub units of the haemoglobin. Haemoglobin is a tetrameric protein made up of 2 alpha sub units and 2 beta sub units and it is the important part of the blood accountable for oxygen passage. Sickle cell is a illness that consequences from a replacement of a polar amino acid identified as glutamate with a non polar one valine at site six of the beta polypeptide component of haemoglobin. The replacement occurs as a consequence of a alteration in one of the bases in the beta-globin gene from adenine to thymine  . As a outcome of this change, the beta polypeptide chains convert sticky in low oxygen circumstances since the valine sticks out of the chain and interrelates with neighboring non-polar amino acids.

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.
