Light energy absorbed by chlorophyll is converted into chemical energy. Some of this energy is used to split water into hydrogen and oxygen. Some of the chemical energy is used to make ATP from ADP and phosphate (Pi). This chemical energy is stored as ATP.
The answers are A) ectoderm and B) endoderm.
Fertilization is a fusion of male and female gametes which leads to the formation of a zygote. The zygote undergoes mitosis and transforms into a single-layered blastula. Gastrulation is a transformation of the blastula into a two-layer or three-layer gastrula. Cnidarians are a diploblastic animal because their gastrula has only two layers - endoderm and ectoderm.
One commonality is the ability to grow and reproduce through the production of new cells; cell division.
Over the past four decades, researchers have identified many types of oncogenes, including growth factor receptors, transcription factors, and intracellular signaling proteins.
<h3>What are oncogenes?</h3>
These are specific genes in an organism that can cause the formation of cancer. These genes are prone to defects that when activate, signal for a cell to become a tumor. The genes listed in the question are some examples of the types of cells that can be oncogenes.
Therefore, we can confirm that over the past four decades, researchers have identified many types of oncogenes, including growth factor receptors, transcription factors, and intracellular signaling proteins.
