Which of the following are true of trans-fatty acids?
pogonyaev

The following given statements are true of trans-fatty acids:

A. Often created by treating plant oils with hydrogen

D. Occur naturally in in food

<u>Explanation:</u>

The unsaturated fatty acids that are produced by a method called hydrogenation through the addition of a hydrogen molecule to vegetable oils is understood as "Trans-fatty acids". According to the hydrogenation process the composition of the fatty acids varies. The unsaturated fatty acids trans structure receives one double conjugated bond and obtains a straight shape and rectifies the twisted shape created by cis bonds.

Increasing the concentrations of trans-fatty acids particularly in the red blood cell membranes can lead to blockage of the blood vessel as a whole and enhance the risk of heart disease. Meat and dairy products kind natural food materials include trans fatty acids.

vlabodo [156]

Answer:

colorblindness

Explanation:

Colorblindness is a recessive sex-linked trait. ... Remember that in incomplete dominance, the two traits blend together; in co-dominance, the two traits are equally expressed; and in sex-linked traits, the traits can be dominant or recessive, but they always appear on the X-chromosome.

A patient is scheduled for a fiberoptic colonoscopy. what does the nurse know that fiberoptic colonoscopy is most frequently use
Naya [18.7K]
During colonoscopy, a flexible Fiberoptic or video colonoscope is used to visualize, examine and photograph the large intestine including the anus, the rectum and the sigmoid, transverse and ascending colon. This procedure is most frequently used for cancer screening and for surveillance in patients with previous colon cancer or polyps. In addition, tissue biopsies can be obtained as needed and polyps can be removed and evaluated. Other uses of colonoscopy include the evaluation of patients with diarrhea of unknown cause, occult bleeding, or anemia; further study of abnormalities detected after a barium enema and diagnosis clarification and determination of the extent of inflammatory or other bowel disease. Colonoscopy is contraindicated if the patient has a suspected or documented colon perforation, acute severe diverticulitis or fulminant colitis.

1. List and explain the difference between the minimum voltage and maximum voltage achieve in a nerve impulse
algol [13]
The normal membrane potential inside the axon of nerve cells is –70mV, and since this potential can change in nerve cells it is called the resting potential. When a stimulus is applied a brief reversal of the membrane potential, lasting about a millisecond, occurs. This brief reversal is called the action potential 
<span>A stimulus can cause the membrane potential to change a little. The voltage-gated ion channels can detect this change, and when the potential reaches –30mV the sodium channels open for 0.5ms. The causes sodium ions to rush in, making the inside of the cell more positive. This phase is referred to as a depolarisation since the normal voltage polarity (negative inside) is reversed (becomes positive inside). </span>

<span>Repolarisation. At a certain point, the depolarisation of the membrane causes the sodium channels to close. As a result the potassium channels open for 0.5ms, causing potassium ions to rush out, making the inside more negative again. Since this restores the original polarity, it is called repolarisation. As the polarity becomes restored, there is a slight ‘overshoot’ in the movement of potassium ions (called hyperpolarisation). The resting membrane potential is restored by the Na+K+ATPase pump.</span>
