Answer:C). A phospholipid bilayer with proteins
Explanation: A cell membrane is a phospholipid bilayer with proteins embedded in it. The fatty acyl chains of the phospholipids are non polar and hydrophobic while the phosphate groups are polar and hydrophilic. The hydrophobic regions of the phospholipids interact with each by facing each other, forming a bilayer with a fluid interior. The polar head groups face outward interacting with the external environment of the cell. Proteins are embedded in this bilayer and they float in this sea of phospholipids. Proteins anchored to the membrane through interactions between the hydrophobic regions of the phospholipids and the amino acid side chains of the proteins. These lipids and proteins swim laterally in each face of the bilayer but movement from one face of the bilayer to another is restricted.
There are four basic types of animal tissue, these are connective, epithelial, nervous, and muscle tissues.
Lederbergs' experiment of the prevalence of mutations before selective culture was proved by replica plating. They spread bacteria on the plate and allowed them to grow. Next, they stamped the growth on the new plate which was already containing penicillin. The bacteria were able to grow on this plate, even when they never exposed to the antibiotic before. This proved that some of the bacteria were already mutated and were not as a result of exposure to selective culture conditions.
Answer:
Forest.
Explanation:
Berries and nuts are typically fruits and products of trees, and there must be plentiful amount in which to have a population (though it states only an organism, but it can be assumed). Brown fur is typically <em>camo</em> against a brownish background, which can be reflected essentially through bark & wood of trees.
*Most likely the given organism is a squirrel, which typically prefer forest or habitats with trees or tree-like objects.
