Which best illustrates how Gregor Mendel used creativity that lead to scientific discovery?O He noticed that traits were passed
Svet_ta [14]
<span>As I know Gregor Mendel - Austrian naturalist, botanist and a religious leader, a monk, founder of the doctrine of heredity (Mendelism). By applying statistical methods for the analysis of results of the hybridization of pea varieties, formulated the laws of heredity. In 1856, Mendel began his experiments in crossing different varieties of peas, differing in a single, strictly defined criteria (for example, the shape and color of seeds). Precise quantitative account of all types of hybrids and statistical processing of the results of experiments that he conducted for 10 years, allowed him to formulate the basic laws of heredity - the splitting and combining of hereditary "factors". Mendel showed that these factors are separated and not crossing merge and disappear. Although the crossing of two organisms with contrasting features (for example, yellow or green seeds) in the next generation of hybrids appears only one of them.</span>

In the fluid-mosaic model of the plasma membrane, the phospholipid molecules are oriented so that the _____________ heads are fa
saveliy_v [14]

Answer:

Hydrophilic heads facing exterior

Hydrophobic tails facing interior

Explanation:

In 1972, the fluid mosaic model was proposed to describe the structure of the plasma membrane. This model describes the plasma membrane to possess components including phospholipids, cholesterol and proteins. The phospholipid component is composed of glycerol, two fatty acids and a phosphate-containing head, which are arranged in two adjacent layers forming the phospholipid bilayer in the membrane of biological organisms.

Phospholipids have both the hydrophilic and hydrophobic region. Hence they are said to be AMPHIPATHIC.

The head of the phospholipid is negatively charged due to its phosphate content, making it polar and hydrophilic i.e. water-loving. This hydrophilic head faces the exterior of the cell in order to interact with fluids.

The tails of the phospholipid are long fatty acids that keep away from water i.e. hydrophobic. Due to their water-fearing nature, they avoid water and face the interior of the cell, where each tail face each other.
