Which of the following blood type genotypes result in the same phenotype? a) I^A I^A and I^A I^B b) I^B I^B and I^B i c) I^B I^B
Lady bird [3.3K]
The letter I is just there. Blood type problems will usually have

I^{A}I^{A} and I^{A}i = blood type A
I^{B}I^{B} and I^{B}i = blood type B
I^{A}I^{B} would be blood type AB
<span>ii would be blood type O.
</span>
So the answer would be B since B is the only option that the offspring would be only blood type B, which is the same as their parents.

It is of paramount importance to use primary, secondary, and tertiary sources in research.
Anestetic [448]

<span>The correct answer is (a) True, it is of paramount importance to use primary, secondary, and tertiary sources in research. Researching includes using primary sources as they contain original materials on which research is based, but also using second sources as interpretations and evaluations as other researcher’s point of view. That also apply for tertiary sources that  represent distillated and collected information of primary and secondary sources.</span>

When a neuron responds to a particular neurotransmitter by opening gated ion channels, the neurotransmitter is serving as which
GrogVix [38]

The question is incomplete as it does not have the options which are:

A) relay molecule

B) transducer

C) signal molecule

D) response molecule

Answer:

C) signal molecule

Explanation:

The transmission of signals in the neurons takes place in the form of electrical energy and chemical energy. The signals get transmitted in the form of electrical signals inside the neurons but when the signals have to be passed on to the next neuron on the pathway then the electrical signals get converted into the chemical signals.

The electrical signals cause the release of the chemical signals molecules called neurotransmitter from the synaptic vesicles in the presynaptic neuron and also opens the gated ion channels at the terminal. The neurotransmitter thus acts as a signal molecule in the transmission of a signal through neurons.

Thus,  C) signal molecule  is the correct answer.

A researcher is studying a population of mutant fibroblasts that fail to flatten and attach to extracellular matrix proteins on
Vladimir79 [104]

Answer: Components of cell junctions

Explanation:

<u>Fibroblasts are cells located in the dermis,</u> responsible for the formation and remodeling of tissue. They synthesize fibers and maintains the extracellular matrix of the tissue of animals. So, t<u>he extracellular matrix is a structurally complex entity that surrounds and supports the cells found in tissues</u>.

A cell junction a structure that exists within the tissues of animals and they consist of protein complexes that provide contact between cells or between a cell and the extracellular matrix. So if the cells do not appear flattened and do not attach to the extracellular matrix, then there is a problem with the components of cell junctions, which are mostly proteins as it was said before. And since proteins are coded by genetic information stored in DNA, then if there is a mutation in any of those genes, the fibroblast will fail to attach because the protein of the cell junction will be abnormal.

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.
