The primary source of energy that drives convection within the atmosphere and oceans is the sun.
Answer: Directional selection
Explanation:
In the population genetics, directional selection is the mode of selection during which the extreme phenotype are favored more than the other phenotype.
This causes the allele frequency to shift towards the time in the direction of that particular phenotype.
Here, in the question the acid tolerant plant species is favored over the other phenotype.
Hence, the correct answer is option D
The correct answer is: A. The hydrophilic head groups of the lipid molecules are exposed to the outside of the cell and the cytoplasm, which is a water-like environment. The hydrophobic tails form an oily layer inside the membrane that keeps water out of the cell.
Plasma membrane of the cell is arranged in a bilayer of phospholipids. Phospholipids are amphipathic molecules which means that they have both hydrophilic and hydrophobic regions. The hydrophilic heads of phospholipids that are faced outward and hydrophobic layer located in the interior of the bilayer together make a good barrier between the interior and exterior of the cell, so the water and other polar or charged substances cannot easily cross the hydrophobic core of the membrane.
In this case, the patient has to be moved into an isolated room or into a private room. Vancomycin resistant-enterococci are said to develop a resistance against vancomycin. Enterococci normally live in our skins and intestines as normal flora, therefore it does not cause any problems. In patients who are immunocompromised, they are more likely to be affected by these organisms which commonly infect the intestines, urinary tract infection and wounds. These bacteria are said the be difficult to treat with since there are lesser antibiotics who have greater strength compared to vancomycin.
Answer:
They might gain or lose weight quickly, unexpectedly, and with no explanation unless thyroid is tested. Some of the symptoms that can occur with metabolic disorders are lethargy, jaundice and seizures. The symptoms expressed would vary with the type of metabolic disorder, mostly calcium metabolic disorders. Increased blood pressure, high blood sugar, excess body fat around the waist.
