Answer: dinosaurs and birds
Plentiful collection of f<span>ossils of early birds and their most immediate predecessors has settled the century-old controversy about the origin of birds. Birds are now safely declared to evolve from a group of dinosaurs known as maniraptoran theropods. Birds have similar shape of the bones as a variety of maniraptorans have. A host of fossils have shown also that the maniraptorans lay looked alike eggs as that of birds and they resemble the birds in the way they laid their eggs also. Those reasons prove that they are most closely related.</span><span>

Answer:
I think is B because at stage 4 we can observe that different kinds of cell formed(the cell on the edge is different from the inner cell)
Explanation:
An intrusion is the action of intruding or intruding. I hope I helped a little!! :-)
Answer:
Monomer: 2 - Amino acid
3 -Nucleotide
Polymer: 1 - Cellulose
3 - Nucleic acids
Example: 1 - Carbohydrates
2 - Collagen
Function 1: Carbohydrates are a source of energy in the body.
Function 2: Collagen is the most abundant protein in the human body. It's a long, fibrous structural protein that supports tissues and gives structure to individual cells. Collagen fibers are tough and found in bundles. They providing tensile strength to the tissues containing them.
Function 3: DNA is a protein structure that carries instructions needed for an organism to develop, survive and reproduce. It is a nucleic acid that contains the genetic instructions for the development and function of living things, its main role is the long-term storage of information
Explanation:
Monomers are single molecules that can bond with identical molecules to form polymers.
1. Glucose can combine with other glucose molecules to form starch or cellulose which results in formation of carbohydrates.
Carbohydrates are a source of energy in the body.
2. Amino acids can combine with other amino acids to form a protein chain which results in formation of collagen
Collagen is the most abundant protein in the human body. It's a long, fibrous structural protein that supports tissues and gives structure to individual cells. Collagen fibers are tough and found in bundles. They providing tensile strength to the tissues containing them.
3. Nucleotides can combine to form nucleic acids resulting in formation of enzymes.
