Answer:
The first line of defence (or outside defence system) includes physical and chemical barriers that are always ready and prepared to defend the body from infection. These include your skin, tears, mucus, cilia, stomach acid, urine flow, 'friendly' bacteria and white blood cells called neutrophils.

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>

I'm pretty sure that these are correct.
All organisms are made up of cells. They all also have different levels of organization, and they also respond and adapt to their environment.
Answer:
Option D, is composed of a fluid bilayer of phospholipids with embedded amphipathic proteins
Explanation:
The fluid mosaic model is the depiction of plasma membrane whose main components are phospholipids, cholesterol, proteins, and carbohydrates.
The structure of plasma membrane consists of two layers of phospholipid molecules which are amphipathic or amphipathic (they possess both polar hydrophilic and non-polar hydrophobic ends).
Protein molecules also possess both polar and non-polar side chains. However, their poly hydrophilic linkages are towards the outer side and non-polar or hydrophobic linkage is towards the inner side.
Option D is correct
