Answer:
The three parts of the cell theory are as follows
(1) All living things are made up of cells
(2) Cells are the smallest units (or most basic building blocks) of life
(3) All cells come from preexisting cells through the process of cell division.
Explanation:
(1) The first characteristic of a living thing is that they are made up of cells. A cell is the basic building block of all organisms. It is the smallest unit of organization in a living thing. They contain the organism's hereditary information (DNA) and can make copies of themselves in a process called mitosis.
(2) Cells make up the smallest level of a living organism such as yourself and other living things. The cellular level of an organism is where the metabolic processes occur that keep the organism alive. That is why the cell is called the fundamental unit of life.
(3) All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms. The activity of an organism depends on the total activity of independent cells. Energy flow (metabolism and biochemistry) occurs within cells.
Answer:
Baleen is a filter-feeding system inside the mouths of baleen whales. The baleen system works by a whale opening its mouth underwater and taking in water. The whale then pushes the water out, and animals such as krill are filtered by the baleen and remain as a food source for the whale. Baleen is similar to bristles and consists of keratin, the same substance found in human fingernails and hair. Baleen is a skin derivative. Some whales, such as the bowhead whale, have longer baleen than others. Other whales, such as the gray whale, only use one side of their baleen. These baleen bristles are arranged in plates across the upper jaw of whales.
Depending on the species, a baleen plate can be 0.5 to 3.5 m (1.6 to 11.5 ft) long, and weigh up to 90 kg (200 lb). Its hairy fringes are called baleen hair or whalebone hair. They are also called baleen bristles, which in sei whales are highly calcified, with calcification functioning to increase their stiffness.[1][2] Baleen plates are broader at the gumline (base). The plates have been compared to sieves or Venetian blinds.

I think they contain covalent bonds, between the carbon atoms and also between the carbon atoms and hydrogen atoms. Polymers consist of chain-like molecules that are in turn, made up of numerous smaller, repeating units called monomers.
