n his experiment McDowell cool place a dying person on a scale and measure their weight immediately prior to the following death. McDowell determined the change and weighed approximately 21 grams for the experiments he concluded the soul exists and has mass what is the fundamental scientific flaw in his conclusions ​

Each round of the citric acid cycle begins when the four-carbon molecule oxaloacetate is converted to the six-carbon molecule ci
Verdich [7]

Answer:

The added carbon is supplied by acetyl CoA and the 2 eliminated carbons are released as CO2.

Explanation:

TCA cycle or citric acid cycle occurs in the mitocondrial matrix.

           The ist step of TCA cycle deals with the formation of citrate molecule bt the addition of Acetyl CoA with oxaloacetate. The acetyl CoA is a 2 carbon compound formed from pyruvate by the catalytic activity of pyruvate dehydrogenase .

          The 2 eliminated carbons are released as carbon di oxide or CO2.The CO2 molecule is eliminated during the formation of alpha ketoglutarate from isocitrate .The second CO2 molecule is eliminated when alpha ketoglutarate is converted to succinyl CoA.

1.Identify the role of endocrine glands in growth/development, and in regulation of metabolism.
DIA [1.3K]

In this question we are going to answer a series of questions about the human endocrine system, hormone release and homeostasis.

<h3>What is human endocrine system, hormone release and homeostasis?</h3>

1. Endocrine glands produce hormones and release them directly into the bloodstream.

Hormones are the products of secretion from the endocrine glands. They control various activities in the human body, hence the importance of these glands.

2. It is through the feedback mechanism that, for example, the regulation of hormone secretion and the control of temperature and blood pressure occur.

Thanks to this control, it is possible to guarantee the harmony of the systems and, consequently, the homeostasis (balance of the internal environment).

3. Hormones can be divided into four groups, based on their chemical structure,form of synthesis and storage, solubility, half-life, form of transport, receptors on cell and mechanism of action:

  • Peptides
  • Steroids
  • Amines
  • and Eicosanoids.

Both positive and negative feedback are extremely important for our body to function properly. However, these two mechanisms have differences. In negative feedback, the body produces a response that reduces the initial stimulus, while in positive feedback, the response reinforces the stimulus.

Match each part of Sammi's model to the bodily structure it represents. One bodily structure has already been labeled for you.
KiRa [710]

Answer:

corrugated cardboard tube - digestive tract

irregular surfaces on the corrugated tube - villi

pump - heart

Plastic tubing - blood vessels

Explanation:

The corrugated cardboard tube represents the digestive tract.  The give away was the presence of the irregular surfaces within the tubes. This is called the villi. The villi is responsible for the absorption of food after digestion into the body.

Irregular surfaces on the corrugated tube represent the villi. They are tiny hair-like structures that are in the small intestine, that are responsible for the absorption of food into the bloodstream.

The pump represents the heart. The heart is the only organ in the body that provides the pressure force that pushes the blood throughout the body. In this model, the pump will most likely be performing the same function.

The plastic tubings are meant to contain one form of fluid or the other. Judging from that, they can be said to represent the blood vessels. This is because they are connected to the heart and are meant to transport bodily fluids around the body
