Question
Chapter 34, Problem 14SQ
Summary Introduction
To examine: Whether the statement “All hormones secreted by arthropods such as crabs and insects are also secreted by vertebrates.” is true or false.
Introduction: The major differences between the vertebrate and invertebrate are that invertebrate lacks well developed backbone or spiral columns and brain. They have structural difference because of the physiological and biochemical distinction between them. Invertebrates produce some unique hormones, especially in arthropods, which play an important role in metamorphosis.

QUESTION 1
Which statement is accurate?
Hormones that differ in effect reach their target cells by different routes through the body
Pairs of hormones that have the same effect are said to have antagonistic functions
Hormones are often regulated through feedback loops
Hormones of the same chemical class usually have the same function
To examine: Whether the statement “All hormones
secreted by arthropods such as crabs and insects are
also secreted by vertebrates." is true or false.

- Why can a single endocrine hormone produce a wider spread of responses in more of the body than a single nerve cell? Group of answer choices Blood can carry all the same hormones throughout the body simultaneously, producing responses all over the body; nerve cells can only target a small number of cells. Nerve cells and blood work together. The endocrine has nothing to do with the nervous system. Endocrine hormones only target a very small number of precise responses. A single hormone can target many different responses, whereas a nerve only targets a single response.arrow_forwardVhich of the following best describes the mechanism of action of lipid-soluble hormones?
