optics disc

No,,thats not correct...the correct answer is optic vesicles. Optic discs is your blind spot. The fourth week of development, the beginnings of the eyes are seen in the optic vesicles.

Embryo development typically requires a suitable environment with proper temperature, nutrients, and oxygen. It also relies on the correct timing and sequence of cell division and differentiation processes. Additionally, genetic information and signaling molecules play crucial roles in directing the development of various tissues and organs.

Yes, microgravity can affect the way seahorse embryos develop by potentially impacting their orientation and growth. Studies have shown that exposure to microgravity can result in changes in gene expression and alterations in cellular processes, which may affect embryonic development in seahorses.

i think it is called Pregnentcy or pregnent woman

No, the majority of animal embryos develop outside the mother's body. This includes animals such as birds, reptiles, and most fish. Embryos that develop inside the mother's body are found in live-bearing mammals as well as some fish and sharks.

The head of the embryo usually grows first during development. This early growth is critical for forming the brain and facial structures.

The first organ to form in an embryo is the heart. It starts to develop early in gestation and is essential for pumping blood and circulating nutrients throughout the body as the embryo grows.

The period of the embryo is from fertilization to 8 weeks of gestation. During this time, the embryo undergoes rapid growth and development, with major organs and body structures forming. By the end of this period, the embryo is referred to as a fetus.

The process when an embryo attaches to the uterus is called implantation. During implantation, the embryo embeds itself into the lining of the uterus, where it will continue to develop and receive nourishment.

No, embryos do not look for their own food outside the egg. They rely on nutrients stored in the egg or provided by the parent until they hatch.

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 )

Twins from one embryo occur when a single fertilized egg splits into two embryos early in development. This results in identical twins who share the same genetic material. This phenomenon is known as monozygotic twinning.

An embryo can develop in the uterus of mammals, including humans, as well as in eggs of birds, reptiles, and fish. In some species, embryos can also develop externally in structures like egg cases or pouches.

The first organ to form in the embryo is the primitive streak, which later develops into the notochord. The notochord plays a crucial role in the development of the nervous system.

An embryo produces a specific type of hemoglobin called fetal hemoglobin (HbF) that has a higher affinity for oxygen than the adult hemoglobin. This allows the developing embryo to efficiently obtain oxygen from the maternal blood supply through the placenta. Once born, the infant starts producing adult hemoglobin to adapt to breathing air in the postnatal environment.

what is the function of food storage

The weight of a human embryo can vary, but on average, it is around 0.1 gram at 6 weeks of development.

An embryo typically consists of a radicle (root) and a plumule (shoot). These are the basic components that develop into the main parts of a plant, with the radicle growing into the root system and the plumule developing into the shoot system.

The instructions on how to build organs are located in the genetic material of the embryo, specifically the DNA. These instructions guide the development and differentiation of stem cells into specific cell types that eventually form the various organs in the body.

The first organ to develop in the embryo is the heart. It starts to form and beat as early as 3 weeks after conception.

The brain and spine begin to develop in the early stages of embryonic development, typically around 3-4 weeks after fertilization. By week 5, the neural tube that eventually forms the brain and spinal cord begins to take shape. This process is crucial for the proper development of the nervous system.

The yolk sac supplies food to the developing embryo through nutrients stored in the yolk. It helps sustain the embryo's growth and development until it is ready to hatch.

Through studying embryos, scientists have found that vertebrate animals seem to have a common design, even though their adult forms are different. Arm buds on different species, for example, look the same early on during embryonic development, yet they will develop into very different forms in the adult (a flipper, an arm, a wing, etc).

No, the mother's blood does not mix with the embryo. The placenta acts as a barrier between the mother's blood supply and the embryo, allowing for transfer of nutrients and waste products without direct mixing of blood.

All developing embryos go through a series of stages, from fertilization to differentiation and organ formation. They also possess a similar genetic code, containing the instructions necessary for development. Additionally, all embryos start as a single cell and undergo cell division to form a multicellular organism.
