How do the unsaturated fatty acids in phospholipids affect the structure of cell membranes?

Biology

ludmilkaskok [199]1 year ago
4 0

Unsaturated fatty acids are a component of the phospholipids in cell membranes and help maintain membrane fluidity. The Phospholipids contain a variety of unsaturated fatty acids, when compressed, the “kinks” in their tails push adjacent phospholipid molecules away, that helps in maintain fluidity in the membrane. Unsaturated fatty acids have at least one double bond, creating a "kink" in the chain, the absence of double bonds decreases fluidity, making the membrane very strong and stacked tightly.

The ratio of saturated and unsaturated fatty acids determines the fluidity in the membrane at a temperature, at appropriate temperatures the phospholipids have enough kinetic energy to overcome the intermolecular forces holding the membrane together, which increases membrane fluidity.

On which of these issues is public opinion less likely to affect policymaking?
11Alexandr11 [23.1K]

Public opinion is less likely to affect fiscal policy making.

There are a number of variables that affect the formulation of a country's fiscal policies, the most important being domestic demand and economic growth.

Public opinion is therefore not a relevant factor that affects the formulation of these policies, it affects more social and environmental policies, for example.

For a better understanding of fiscal policy, we must understand the concept of taxation.

Taxation is a financial obligation on individuals and organizations, whose main objective is to improve the economy and public services so that there is a fairer and more equal society.

Some examples of taxes:

  • Income tax
  • payroll tax
  • sales tax

Therefore, public opinion is more likely to affect the formulation of social and environmental policies than fiscal policies. Because it is capable of instituting new ideas and social awareness that can directly affect legislation.

What is the ratio of surface area to volume for a sphere with the following
Leya [2.2K]

Answer:

0.4\ \frac{1}{m}

Explanation:

Let

x ----> the surface area of a sphere

y ---> the volume of a sphere

we know that

The ratio of surface area to volume of a sphere is equal to divide the surface area by the volume of the sphere

\frac{x}{y}

we have

x=588\ m^2\\y=1,372\ m^3

substitute the values

\frac{588}{1,372}=0.4\ \frac{1}{m}

timofeeve [1]
The correct answers are a, c, d.
There are three types of capillaries: continuous, sinusoidal (or discontinuous) and fenestrated. Continuous capillaries are the most common type and they form tight junctions. Sinusoidal capillaries form an incomplete lining with several gaps, which allow red and white blood cells and some serum proteins to pass. These capillaries are mainly found in the bone marrow, lymph nodes and adrenal glands. Finally, fenestrated capillaries facilitate the movement of smaller molecules and plasma proteins and are mainly found in the small intestine. The majority of the fluid transport happens through the fenestrated capillaries.
