Polygenic inheritance. The characteristics of a person aren't controlled completely by a single gene, but rather several genes that generally only make a small contribution to how the child turns out in the outcome. At one point there was a study that showed over 400 genes were linked to height, so imagine any other characteristics of a person. Environmental effects also serve a large purpose in how a child is to turn out. These children may all be growing up in the same environment, however that's not to say they all grow up the same. They could all be treated the same way and react differently to it, this counts both for physical and mental traits. All human's features such as eye colors, hair color and height are determined by several different genes. As an example, there are around 2 major eye color genes, however there are also around 14 different genes that actually contribute in determining a person's exact eye color. Some are bound to look the same, as they have the same parents, however, just because they have the same parents doesn't mean they all will look exactly alike.
Answer and explanation:
<u>If excessive amounts of acetoacetic acid were to build up in the body, </u><u>the pH of the blood would decrease</u><u>, because the blood would become more acidic</u>.
Acetoacetic acid is produced because of lipolysis (fat degradation) or because of the breakdown of amino acids. This is a normal biochemical process, but it can lead to serious issues when the levels of acetoacetic acid rise more than they should.
<u>Patients with Diabetes Mellitus have a deficiency in their insulin production</u>. Insulin is the only hormone that can make glucose enter the cells, which is important because glucose (sugar) is processed inside the cells to produce ATP (a molecule high in energy).
Patients with Diabetes can't get the glucose inside their cells, so the blood sugar levels rise in the blood (hyperglycemia). <u>Since the body still needs ATP to function properly, energy requirements are being met via the degradation of fat and amino acids - which generates acetoacetic acid. If this continues, the pH drops and</u><u> Diabetic Ketoacidosis</u><u> occurs</u>. This condition is life-threatening.
First, the yellow fever virus is phagocytosed by white blood cells. The phagocytosed white blood cell then travel through the lymph vessel. Since lymph node contain white blood and filter lymph, the yellow fever phagocytosed with white blood cell establish in the lymph node.
Answer:
Explanation:
Taigas have few native plants besides conifers. The soil of the taiga has few nutrients. It can also freeze, making it difficult for many plants to take root. The larch is one of the only deciduous trees able to survive in the freezing northern taiga.
