We have 20 different amino acids in our bodies.
Smooth muscle cells are found in the walls of hollow organs
Answer:
They have helical thickening of lignin in their walls to prevent collapse
Explanation:
the primary function of Xylem and its conducting vessels tracheids is to provide support and tranport water and minerals in plants.
Xylem vessels have layers of dead materials in the walls called LIGNIN. Lignin is a polymer; a very strong, hard materials that stop water passage through it,because it contains dead cells,
Therefore the presence of deposit of these strong impermeable, ligified walls in its walls prevent its collapse during mass flow of water of transpiration pull.

Answer:
A. Sexual Reproduction creates genetically different offspring.
Explanation:
Sexual Reproduction is created through 2 different opposite parties, in which the product takes around half of the genes from each individual parties. The traits that are shown are then decided on whether or not they are dominant or recessive or non-existent.
In a Asexual Reproduction, the reproductive capabilities of both parties are found inside one organism. The organism is able to produce both the sperm and egg, and therefore do not need a partner to reproduce. This means that the DNA inside the body is the only source for production, and that there will be very little variation in the DNA.
