Answer:

Explanation:

Lipids are made of very long carbon chains connected to other carbons and hydrogen. These chairs can be connected to another molecule such as glycerol. Examples of lipids are triglycerides, cholesterol, and phospholipid that differ in the length of their chains and also the number of double bonds in these chains. These chains - that are the main characteristic that defines lipids - are hydrophobic.

Answer:

68.74%

Explanation:

To find the Standard Deviation:

First find expected return.

(0.7*100%)+(0.3*-50%) =70-15= 55%

Then the Variance.

[0.7*(1-0.55)^2]+[.3*(-0.5-0.55)^2]

=0.14175+0.33075

=0.4725

=47.25%

The Standard Deviation is the square root of the variance.

$\sqrt{0.4725}$

=0.6874

=68.74%

Which of these features is found only in arteries?

Fantom [35]

Answer:

-elastic membranes

Explanation:

The elastic membrane or tissue of the arteries allows the artery to bend and fit. It is important for artery to be elastic, because it transports oxygenated blood pumped from the heart to the tissues (except for pulmonary artery which carries deoxygenated blood) and thus have a blood pressure that is higher than in other parts of the circulatory system.
