The pollen grains contain sperm which will fertilize the egg and create a seed to sprout the next generation of plants. The main male part is the stamen. It is divided into two parts: the anther and the filament. The anther produces the pollen grains that contain the sperm needed for fertilization.
Answer:
Porifera—gastrovascular cavity, coelomate.
Explanation:
Sponges do not contain digestive system but obtain nutrients through the diffusion process. Porifera is the most commonly asymmetrical in nature but can also have radial symmetry. Porifera has no coelom.
Lacking a true digestive system, they depend on the intracellular digestive processes of their choanocytes for their energy intake. Gas exchange, circulation, and excretion occur by diffusion between the water and the cells.
1. It is passed from the parents to the offspring.
2. Genes that determine each trait are located in chromosomes and are passed from parents to their offspring during reproduction.
3. genes
4. Height in a human being is determined by the sets of chromosomes found on genes obtained from each parent.
5. It creates new daughter cells to replace parent cells
15. 19 chromosomes
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

3. Nucleotides can combine to form nucleic acids resulting in formation of enzymes.
