<span>Endocrine glands are ductless or tubeless organs or groups of cells that secrete hormones directly into the bloodstream.</span> <span>The endocrine glands are part of the endocrine system and include the pineal gland, pituitary gland, pancreas, ovaries, testes, thyroid gland, parathyroid gland, hypothalamus and adrenal glands. The endocrine system maintains homeostasis, controls the growth and development, controls metabolism (body energy levels), reproduction, response to stimuli (stress and/or injury).</span>

What will happen to the concentrations of ATP,NADPH, and sugar when you add paraquat
docker41 [41]

Answer:

Decrease

Explanation:

Paraquat can induce alterations in endoplasmic reticulum that might contribute to the changes in glucose-6-phosphatase activity, resulting in an increase of blood glucose level and/or all the effects can be attributed to a high level of circulating epinephrine produced by paraquat toxicosis. Paraquat induces mitochondrial dysfunction and ATP depletion in brain tissues or cultured cells (54,62). Therefore, our in vivo findings of ATP depletion would be a contributory factor for the observed proteasome dysfunction. The two reactions use carrier molecules to transport the energy from one to the other. The lower energy form, NADP+, picks up a high energy electron and a proton and is converted to NADPH. When NADPH gives up its electron, it is converted back to NADP+

rewona [7]

.......is secreted into the bloodstream, whereas _____ is secreted into mucus such as gastrointestinal fluid, colostrum, saliva, tears, and sweat:

a. Monomeric IgM; pentameris IgM

b. Monomeric IgA; dimeric IgA

c. Monomeric IgA; dimeric IgM

d. Dimeric IgA; monomeric IgA

Answer:

b. Monomeric IgA; dimeric IgA

Explanation:

IgA is a class of antibodies that are found mainly in body secretions. In sweat, tears, saliva, mucus, breast milk, and gastrointestinal secretions, IgA is secreted as a monomeric antibody. Smaller quantities of this class of antibodies are also present in blood and lymph. However, IgA is present in a dimeric form in the bloodstream. It makes up 10–15% of all antibodies in the blood. The main function of this class of antibodies is to give localized protection of mucous membranes against bacteria and viruses.

Describe how lymph nodes and organs help the immune system fight pathogens.
I am Lyosha [343]

The defense system of the human body is made up of entire organs and vessel systems like the lymph vessels, but also of individual cells and proteins. The inner and outer surfaces of the body are the first barriers against pathogens (germs). These surfaces include the skin and all mucous membranes, which form a kind of mechanical protective wall.

Several things support this protective wall:

<span><span>- The body’s own antibacterial substances can disable different pathogens from the environment at an early stage. A certain enzyme found in saliva, the airways and tear fluid destroys the cell walls of bacteria.
</span><span>
- Many pathogens that are breathed in get stuck to mucus in the bronchi and are then moved out of the airways by hair-like structures called cilia.
</span><span>
- Most pathogens that enter the body together with food are usually stopped by stomach acid.
</span><span>
- Normal flora, harmless bacteria that reside on the skin and many mucous membranes in the body, also help to protect the body.</span></span>

The cough and sneeze reflex can also help to remove pathogens.


Hope this helps (:
