Answer:lipid molecules

Explanation:

lipid molecules prevent membrane from dissolving and they are also known as phospholipids.

A lipid molecule could be imagined as rectangle. With one end i.e the bottom of the lipid molecule that is hydrophilic which means they are water-loving.

The other end of the head of the lipid molecule which is hydrophobic, which is the non-polar and water-fearing end of the molecule.

Within protective layer surrounding the outside cell(Cell membrane) there are large amounts of lipid molecules. Phospholipids are the most abundant that prevent membrane from dissolving.

Water is a polar solvent and prefers dissolving polar molecules such as salt but Lipids is a non polar molecule and can't be dissolved by water the presence in abundance prevents dissolution.

How does the diversity of life in the sublittoral zone compare to that of the upper intertidal zone?
Svet_ta [14]
The correct option is this: THERE IS MORE BIODIVERSITY IN THE SUBLITTORIAL ZONE COMPARE TO THE UPPER INTERTIDAL ZONE BECAUSE THERE IS LESS TEMPERATURE VARIATION IN THIS REGION.
The sublittorial zone refers to the part of the ocean that is about 200 meters away from the surface. The zone is characterized by constant temperature as a result of the constant sunlight that reaches the depth; this leads to more biodiversity in this zone.

valkas [14]

Large debris and floodwaters can cause structural damage to bridges and roadways, making travel impossible. Power, telephone, and cable lines can be taken out by flash floods as well. Flood waters can disrupt or contaminate ground water, making tap water unfit for consumption.

<h3>What are the consequences of flooding?</h3>

The cases of flooding in the basin generate numerous negative impacts on the population's quality of life, the consequences of these events are:

  • the difficulty in urban mobility
  • loss of real estate value of homes
  • which may be affected in these events
  • material loss problems

With this information, we can conclude that Floods have large social consequences for communities and individuals. As most people are well aware, the immediate impacts of flooding include loss of human life, damage to property, destruction of crops, loss of livestock, and deterioration of health conditions owing to waterborne diseases.

lianna [129]

Answer:

25%

Explanation:

According to this question, a seek stored seeds of a rare and endangered plant. In order to ensure that the seeds remain fresh, 120 seeds are selected to be grown. However, out of these 120 seeds, only 90 germinated. This means that only 90 of 120 seeds are fertile.

This further means that (120-90) = 30 seeds are infertile and hence, could not germinate. In percentage, this can be represented as:

30/120 × 100

= 1/4 × 100

= 100/4

= 25% of the selected seeds are infertile.
