Nerves branch in intervals from which of the following structures in a chordate embryo? (1 point)

tail
pharyngeal pouches
notochord
hollow nerve cord

The correct answer is option D, " hollow nerve cord"

Reason -

A hollow nerve cord primarily called a Dorsal Hollow Nerve cord during development from ectoderm branches and rolls into a hallow structure. In Chordate the hallow nerve lies at the top of an species or it is located near to the notochord. This nerve cord in the chordates develops into the brain and spinal cord which later on forms the part of central nervous system.

endocrine glands secrete hormones into the blood stream near them; the hormones then travel in our bloodstream until it reaches its destination, called a target cell, in distance parts of the body. in the target tissue, hormones lock onto the target’s plasma membrane, called the receptor site.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
