Factors in an enviroment change so species also need to evolve
"This era includes 3 well known periods called the Triassic, Jurassic, and Cretaceous periods."
In 1895, Ernest Overton proposed that cell membranes were made of lipids
According to the lipid bilayer theory, which Gorter and Grendel put forth in 1925, the cell membrane bilayer structure can be described using crystallographic research and observations of soap bubbles.
<h3>What is Cell membrane ?</h3>
All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment.
- A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane.
- Biological membranes serve three main purposes. First, they prevent harmful substances from entering the cell. Second, they have receptors and channels that let certain molecules, like ions, nutrients, wastes, and metabolic products,
- Third, they divide metabolic processes that are necessary but incompatible that take place within organelles.

Answer:
any of a large group of vertebrate animals that live in water, breathe with gills, and usually have fins and scales
Explanation:
antagonism
When two hormones cancel each other out or have opposite effects it is called antagonism.
<h3>What is an example of antagonism?</h3>
- Traditional examples of antagonistic hormones include insulin and glucagon.
- In contrast to glucagon, which stimulates glycogenolysis, or the conversion of glycogen to glucose, insulin stimulates glycogenesis, or the conversion of glucose to glycogen.
<h3>What does the term "antagonistic hormones" mean?</h3>
- Antagonistic hormones are those that work to bring body circumstances back from extremes to within acceptable bounds.
- An illustration of how the endocrine system maintains homeostasis through the action of antagonistic hormones is the regulation of blood glucose concentration (by negative feedback).
<h3>How do antagonists to hormones function?</h3>
- Infertility, endometriosis, and uterine fibroids are just a few of the diseases that gonadotropin releasing hormone (GnRH) antagonists are used to treat in women.
- GnRH is a hormone released by the hypothalamus that is the target of GnRH antagonists, which stop it from functioning.
