What are the only to tipontent cells in humans?
Embryonic stem cells are.
What is the development at an early stage for humans pets and petunias called?
The development at an early stage for humans is called embryonic development, for pets is called embryonic or fetal development, and for petunias is called seed germination and seedling development.
What is norochord?
The notochord is a flexible rod-like structure found in embryos of chordate animals, including humans. It provides support and helps define the axis of the body. In many vertebrates, the notochord develops into part of the spinal column.
How does animal cell structure differ from that of humans?
Animal cell structure differs from that of humans because humans have several billion cells and animals sometimes only have one. However, the basic structure of each cell is similar.
Which organisms have embryonic stages the most similar?
Organisms that are closely related evolutionarily tend to have embryonic stages that are more similar. For example, mammals such as humans and mice have similar embryonic stages due to their close evolutionary relationship. Conversely, organisms that are more distantly related, like mammals and insects, have more differences in their embryonic development.
The lungs of humans form from the embryonic foregut?
True.
What are the animals in which the anus develops before the mouth?
Animals in which the anus develops before the mouth belong to a group called deuterostomes. Examples include echinoderms (such as starfish and sea urchins) and chordates (which include vertebrates like humans). During early embryonic development in deuterostomes, the blastopore develops into the anus first, with the mouth forming later.
Are humans chordates?
Yes, humans are chordates. Chordates are organisms that belong to the phylum Chordata, which includes animals possessing a notochord at some stage of their development. In humans, the notochord is present during embryonic development and eventually develops into the spinal cord.
What are the only to tipontent cells in humans?
Embryonic stem cells are.
What is the development at an early stage for humans pets and petunias called?
The development at an early stage for humans is called embryonic development, for pets is called embryonic or fetal development, and for petunias is called seed germination and seedling development.
Can you define schizocoely and explain its significance in developmental biology?
Schizocoely is a type of embryonic development where the coelom forms from splits in the mesoderm. This process is significant in developmental biology because it is a common way for the body cavity to form in many animals, including humans. It plays a crucial role in shaping the overall body plan and organ development during embryogenesis.
Which gender develops first?
In the development of humans, the default is female. That is the reason that all humans have nipples.
What are the key stages in the pregnancy cycle of humans?
The key stages in the pregnancy cycle of humans are fertilization, implantation, embryonic development, fetal development, and childbirth.
In a rabbit the embryo normally develops within the?
uterus, just like humans
How does leukemia spread among humans?
it isn't spread, it develops from other causes
What countries recently approved Embryonic Stem Cell Experiments on Humans?
As of 2021, the countries that have recently approved embryonic stem cell experiments on humans include the United States, the United Kingdom, Japan, and Sweden. These countries have regulations and guidelines in place to govern the ethical conduct of such experiments.
