2.  hydrolyzed or removed

Explanation:

GDP, (Guanosine diphosphate) is a biological term, that is made of composition including pyrophosphate group, a pentose sugar ribose, and the nucleobase guanine and it is made from GTP ( Guanosine triphosphate ) dephosphorylation by the ribonucleotide reductase. This enzyme is inactive when hydrolyzed or removed, and then eventually bound to its master regulatory pocket.

Which of the following reflects the relationship between the posterior and the anterior pituitary glands?A. Unlike the posterior pituitary, the anterior pituitary makes and releases its own hormones without input from the hypothalamus.B. One is always a little behind.C. The anterior pituitary is under the control of the hypothalamus but the posterior pituitary is not.D. Unlike the posterior pituitary, the anterior pituitary releases "releasing or inhibiting" hormones.E. The posterior pituitary releases neurohormones and the anterior pituitary releases hormones.F. They are both extensions of the hypothalamus.

Answers

Answer:

The correct answer is - option E.

Explanation:

The anterior and posterior pituitary glands are he two distinct lobes of the pituitary gland which is controlled by the hypothalamus. The anterior lobe of the master gland is receives its signals from the specific neurons of the hypothalamus known as parvocellular neurons and produces six hormones that release in to circulation by itself.

On other hand the extension of the hypothalamus or the posterior pituitary gland receives the neurohormones from the hypothalamus such as oxytocin  and ADH. Neurohormones are the hormones that are released by neurons of the posterior pituitary gland.

Thus, the correct answer is option E.

Answers

Answer:

Bacteria

Explanation:

Nitrogen fixation is the step of the nitrogen cycle that occurs with the help of microbes. Bacteria transform the nitrogen into a usable form for the plants. Thus, option a is correct.

What are nitrogen-fixing bacteria?

The nitrogen cycle is the part of the biogeochemical cycle that converts nitrogen into other forms that can be used by plants. The nitrogen is converted through the nitrogen-fixing bacterias.

The nitrogen-fixing bacterias are heterotrophic in nature that lives freely in the soil. A few examples are Bacillus, Azotobacter, Clostridium, etc. These bacterias transform the atmospheric nitrogen into usable compounds called ammonia which is the fixed nitrogen and can be used by the plants.

Therefore, nitrogen-fixing bacterias transform nitrogen.

What are two theories proposed to explain Primate Origins and how do they relate to traits we see in modern primates

Answers

Answer:

The level of specialization is given by the function.

The function of the organ makes the cell as it becomes mature, its more specific function becomes.

First, a stem cell differentiates itself into a hepatic or neuronal cell, thus generating that its functions are limited compared to the rest of the stem cells.

After this process, throughout the cell development and maturation of the organ, its cells become more specific in a single activity.

Explanation:

The differentiation of the stem cells is regulated by the genetic code, the migration of these during the embryonic stage of the mouse and the external stimulation that these stem cells perceive.

A research team discovered that a novel hormone X stimulates an enzyme that hydrolyzes proteins in the small intestine. However, when hormone X was added to a test-tube mixture containing the enzyme and proteins, no breakdown occurred.

Required:
a. Why is this the case?
b. Name ONE signal transduction pathway that hormone X is using to transfuse its signal. (write all the steps and intermediates)

Answers

Answer:

a. It is a hormone that acts upstream in the signaling pathway (i.e., acting as a ligand by binding to cell receptors)

b. Dopamine-mediated pathways  

Explanation:

It is well known that many cellular transduction pathways are activated via binding of signaling molecules (ligands) to receptors capable of triggering signaling cascades into the cell. For example, dopamine is a signaling hormone (neurotransmitter) involved in diverse brain processes (i.e., motor control, emotional response, etc). It is a neurotransmitter that binds to dopamine receptors and then stimulates the enzyme adenylate cyclase in a process that subsequently activates the production of the second messenger cyclic adenosine monophosphate (cAMP). Finally, cAMP acts as an intracellular signal transductor that play roles in many biological processes by transferring into the cell the effects of dopamine.

Apoptosis differs from necrosis in that necrosis:_______ a. requires the reception of an extracellular signal. b. causes DNA to fragment. c. causes cells to swell and burst, whereas apoptotic cells shrink and condense.d. involves a caspase cascade

Answers

Answer:

c. causes cells to swell and burst, whereas apoptotic cells shrink and condense

Explanation:

These two mechanism are responsible for death of cells in multi cellular organisms.Apoptosis is  naturally occurring process which is well organised and programmed.It is ensures the  automatic death of old and worn out cells, needed for certain cellular developments. This is demonstrated by DNA fragmentation,cell shrinkage,and the break down of the nuclear walls.It can be initiated through two pathways of intrinsic and extrinsic,The latter leads to death from internal factors,while in the former is when external factor causes the death .

However,when cell death is influenced by external factors(toxins)  in the cell environments,which lead to unpredictable or unregulated process leading to cell death ,the process is called Necrosis.it is demonstrated with the swelling and busting of the cell.and characterised with inflammation. It is an accidental death which causes injuries to the cells and tissues.

Vaccination is a process of injecting a dead or weakened form of a pathogen into the body. How does this help strengthen the immune system? It allows the body to increase its internal temperature. It allows the body to regulate the inflammatory response. It allows the body to keep pathogen information for future infections. It allows the body to increase its desire to eat healthy food.

Answers

Answer:

It allows the body to keep pathogen information for future infections.

Explanation:

Vaccination is the process whereby a substance called VACCINE is injected into body in order to prepare the immune system for resistance against infections. A vaccine contains the harmless or dead version of a pathogen called ANTIGEN, which functions to give the immune system defense mechanism against that form of pathogen in future.

The vaccine works by stimulating the immune system of the body to fight against the antigens in the same way it will fight against an actual pathogen in the future. Hence, the body keeps the information on how to combat such pathogens when there is an actual infection.

-----------------------------

There are four principal layers composing the digestive tube walls.  

From the lumen to the exterior of the tube, we can find,

Mucosa Layer

Composed of lining epithelium, a propria lamina of connective tissue, and a smooth muscle layer.

The epithelium works as a barrier that separates the lumen from the organ.

Propria lamina has glands, vessels that get the absorbed substances, and immune system elements.

The smooth muscle delimitates the mucose from the submucosa layer. It produces movements that are independent of the rest of the organ's movements.

Submucosa Layer

Dense connective tissue is placed under the mucosa.

It has bigger vessels that ramification to the mucose, muscle layer, and serosa layer.

In certain areas, this layer also has glands.

Muscle Layer

Composed of two or three concentric smooth muscle layers that differ in their orientation.

The contraction of these layers mixes and propels the content of the lumen of the digestive tube.

Serosa layer

Connective tissue membrane covered by simple plane epithelium.

High caliber vessels are placed in this layer and limphatic vessels.

There are regions of the digestive tube where there is no serosa layer. Instead, there is a connective tissue named the adventitious layer.
