solong [7]3 years ago
5 0

Answer:

Option (1), (3) and (5).

Explanation:

Positive feedback mechanism also exist in the environment that increases the causative effect of the environment. The environment can change the temperature, precipitation and other climatic conditions of the area.

The lack of moisture in Sahara desert and deforestation can cause the trees extinction. The temperature can be increased by the green house gases as the warm atmosphere causes evaporation. The snow gets melted due to increase in temperature and the ground becomes more darker.

Thus, the correct answer is option (1), (3) and (5).

In the fluid-mosaic model of the plasma membrane, the phospholipid molecules are oriented so that the _____________ heads are fa
saveliy_v [14]

Answer:

Hydrophilic heads facing exterior

Hydrophobic tails facing interior

Explanation:

In 1972, the fluid mosaic model was proposed to describe the structure of the plasma membrane. This model describes the plasma membrane to possess components including phospholipids, cholesterol and proteins. The phospholipid component is composed of glycerol, two fatty acids and a phosphate-containing head, which are arranged in two adjacent layers forming the phospholipid bilayer in the membrane of biological organisms.

Phospholipids have both the hydrophilic and hydrophobic region. Hence they are said to be AMPHIPATHIC.

The head of the phospholipid is negatively charged due to its phosphate content, making it polar and hydrophilic i.e. water-loving. This hydrophilic head faces the exterior of the cell in order to interact with fluids.

The tails of the phospholipid are long fatty acids that keep away from water i.e. hydrophobic. Due to their water-fearing nature, they avoid water and face the interior of the cell, where each tail face each other.
