How do fish grow and develop?
Fish grow and develop through a process called indeterminate growth, meaning they continue to grow throughout their lives. They start as eggs, hatch into larvae, and then grow into juveniles and finally adults. Their growth is influenced by factors like genetics, environment, and food availability.
What is the first organ to develop in the embryo?
The first organ to develop in the embryo is the heart. In a fetus, there is a brain, but it isn't fully developed and can't understand signals from the nervous system. Therefore the first functional organ would be the heart. But the first thing to start developing in a fetus is the nervous system. ( no that isn't an organ )
What are the five things that must happen before a human embryo can start to develop?
Before a human embryo can start to develop, the sperm must fertilize the egg, forming a zygote. The zygote must then undergo several rounds of cell division to form a blastocyst. The blastocyst must implant into the uterine lining, and the process of gastrulation must occur, where the three primary germ layers are formed. Finally, organogenesis begins, leading to the development of organs and tissues.
