Neurons in the hypothalamus regulate the activity of secretory cells in the anterior pituitary gland by:________
Jet001 [13]

Neurons in the hypothalamus regulate the activity of secretory cells in the anterior pituitary gland by releasing hormones. Pituitary gland basically store the hormones which is produce by the hypothalamus.

Hypothalamus connect the nervous and endocrine systems by way of the pituitary gland. Both are connected directly to the pituitary gland by a thin stalk which is called infundibulum.

Its main function is to secrete releasing hormones and inhibiting hormones that stimulate  the production of hormones in the anterior pituitary. FSH and LH both are produce and secret gonadotropins which regulated by the hypothalami releasing hormone, GnRH.  These are the releasing hormones which control the release of another hormone.

To learn more about the infundibulum here

Match the type of of evidence for evolution with the correct example. analogous structures vestigial structures homologous struc
gogolik [260]

• Homologous structures: Both Ostriches have wings similar in form to those of their ancestors, but that do not allow the birds to fly.

Homologous structures are those that have structural similarities but are different in function. For example, if we look at the anatomical structure of a bird’s wing, it is very similar in structure with a human arm. However, over the course of time they have evolved to perform different functions.

• Vestigial structures: The inner ear bones of mammals have evolved from bones that form the jaws of reptiles.  

Vestigiality refers to the process in which some structure lose their function over the course of evolution in some specie but they are functionally normal in other species.  Such a structure is the inner ear bones of mammals which donot perform an important function in mammals but do perform in reptiles.

• DNA sequence data: Both Genes involved in RNA replication are conserved among bacteria and animals, suggesting a common evolutionary origin.

The sequencing of genetic data is an excellent method of finding the evolutionary histories and relatedness of different organisms. This field of sciences is called phylogenetics and the mentioned example is the result of phylogenetics.

• Analogous structures: The jointed legs of insects and vertebrates arose independently, indicating a different evolutionary origin.  

Analogous structures are those that have similar function but they look very different in structure or anatomy. This is because they have been evolved from different ancestors and perform different functions. One example of these structures is mentioned, The jointed legs of insects and vertebrates that look different bur perform same function.
