Shells are considered biotic because they come from living things. Biotic describes something living or use to be living such as plants and animals. So shells are considered biotic because they come from a living organism.

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.
As a result of mitosis, each of your body cells is
c. is genetically identical to all others
Explanation:
During cellular division, the chromosomes, that have already duplicated, condense and fasten to spindle fibers that pull one copy of every body to opposite sides of the cell. The result's 2 genetically identical daughter nuclei. the remainder of the cell might then still divide by organic process to supply 2 daughter cells.
We are considered coelomates.
The amoeba is a eukaryote whose bodies most often consist of a single cell.
The cells of amoebae, like those of other eukaryotes, possess certain characteristic features. For example:-
1. Their cytoplasm and cellular contents are enclosed within a cell membrane.
2. Their DNA is packaged into a central cellular compartment called the nucleus.
3. They contain specialized structures called organelles, which execute a range of cellular functions including energy production and protein transport.
