Answer:
Brassinosteroids are synthesized from phytosterols and they promote plant growth and development by modulating cellular processes (e.g, cell division, elongation, photomorphogenesis, responses to environmental stimuli, etc).
Explanation:
Brassinosteroids are phytohormones similar to steroid hormones. Phytosterols include sitosterol, campesterol, and stigmasterol, i.e., lipid (cholesterol) molecules that form the cell membranes. These polyhydroxylated steroidal phytohormones play a wide range of cellular roles during plant growth, development and immunity. Examples of brassinosteroid functions include plant development, xylem differentiation, responses to biotic/abiotic stresses, reproduction, etc. For example, campesterol, which is a precursor of brassinosteroid hormones, is an integral membrane component that functions during plant embryogenesis by regulating the permeability of cell membranes and by altering membrane-associated proteins, as well as signal transduction pathways.
Bacteria have 1 cell, they reproduce asexually and create other 1 cell bacterium.
Q. The brain and spinal cord are known as the central nervous system (CNS). The spinal cord contains nerves that send information to and from the brain. The ___________ is a bundle of nerve tissue at the base of the brain that connects the cerebrum to the spinal cord and sends messages between different parts of the body and the brain.
A. the spinal cord
Answer:There are three mechanisms of horizontal gene transfer typically used by bacteria: transformation, transduction, and conjugation. Transformation allows for competent cells to take up naked DNA, released from other cells on their death, into their cytoplasm, where it may recombine with the host genome.
Explanation:
