Which of the following best summarizes how hormone levels are controlled?
anastassius [24]

Answer:

Option A, Hormones are controlled by a feedback loop; information about a system is sent back to the controller of the system to improve its function.

Explanation:

Negative feedback loop controls the hormone production and release. This is done by eliciting the release of substances till a certain level after which the stop signal is activated thereby preventing further release. By this method,  concentration of hormones in blood is maintained within the narrow range.  

For example – Thyroid hormones is released when the anterior pituitary signals the thyroid. This continues till the hormones in the blood reach the threshold level. Once the threshold level is reached, hypothalamus receives a feedback and then signals anterior pituitary to inhibit further signaling to the thyroid

Hence, option A is correct

Hi,

Sample Response: A flood  would affect the availability of a material used in making a synthetic polymer. If a flood destroys rubber trees, the availability of natural rubber would decrease, which would in turn decrease the production of synthetic polymers.

Have a great day! (This is late but for anyone else who needs it here you go.)

What is the relationship between Endomembrane System, Insulin and Insulin Receptor, activation by phosphorylation, membrane-boun
mars1129 [50]

Answer:

The relationship between endomembrane system, insulin and insulin receptor, activation by phosphorylation, membrane-bound polyribosomes, and glucose transport channels is the eukariotic cell, because within it, they work together with the organelles to modify, summarize and transport lipids and proteins from the gut and absorb nutrients.

Explanation:

The Endomembrane system varies from membranes and organelles, but basically, it is structured by the nuclear envelope and lysosomes, the plasma membrane and several cytoplasmic organelles, as the ER, the Golgi apparatus, secretory granules, vesicles, lysosomes, endosomes, and the endoplasmic reticulum all working together to transfer, modify and package lipids and proteins macromoecules to the eukaryotic cell, from one part of it  to another, and from in to the outside of it also.

The membrane bound polyribosomes are attached to the cell endoplasmic reticulum. The bound ribosomes, used within the cell membrane or expelled from the cell by exocytosis, will produce insulin and they will become membrane bound to control the intake, protein modifications, fusion lipids and sugar breakdown. The insulin is a membrane bound polyribosomes protein synthesized in the ER, which travels along the endomembrane system. This hormone controls glucose and lipid metabolism  or energy function, if glucose level is high, insulin synthesis is activated.  

Synthesized and traveling through the endomembrane system, the insulin gets to its receptor called tyrosine kinase and activates it, phosphorylating and recruiting different substrate adaptors.

 The brand new insulin polypeptide chains go directly into the endoplasmic reticulum by the ribosome and then transported to where they are needed as insulin regulates sugar uptake into adipose tissue and skeletal muscle through glucose transport channels or glucose transporters GLUT4 within vesicles, which are directed to the plasma membrane, this is also the gut and nutrient absorption.

Systematists have used a wide variety of traits to reconstruct the phylogenies of particular groups of organisms. Which one of t
Effectus [21]

Answer:

5. all of the above traits combined

Explanation:

Phylogeny has to do with the study of evolutionary relationships among living organisms based on the premise of the theory of organic evolution that states that all living organisms came from a common ancestor.

Phylogeny incorporates molecular, morphological, anatomical, biochemical and behavioural traits in order to arrive at a phylogenetic tree that represents ancestral lineages.

<em>Hence, the correct option is option 5. </em>
