<span>According to Selye (1956, 1976), the resistance phase of the general adaptation syndrome is responsible for the person making efforts to cope with the threat.</span>
There are three phases in the <span>Hans Selye's General Adaptation Syndrome (GAS). The first one is the Alarm (</span>organism becomes mobilized to meet the threat) . The second is Resistance, and the third is the Exhaustion (it occurs
if organism fails to overcome threat).
Explanation:
In amoeba respiration takes place through its cell membrane also called the plasma membrane. Amoeba gets oxygen gas dissolved in surrounding water through its plasma membrane by the process of diffusion. The oxygen gas diffused inside the body is used up by the amoeba. In the body, the oxygen gas absorbed is used to break down the complex food material into simple molecules. During these metabolic reactions in the body of amoeba, the oxygen gas is converted into carbon dioxide gas. The carbon dioxide gas is also liberated in the surrounding water through the same process of diffusion.
Since amoeba needs oxygen for respiration, the type of respiration is aerobic respiration.
Answer:
The stratosphere is a layer of Earth's atmosphere. ... The troposphere, the lowest layer, is right below the stratosphere. ... Because of this, jet aircraft and weather balloons reach their maximum operational altitudes within the stratosphere. ... from the bottom of the stratosphere up to altitudes of 40 or 50 km (25 to 31 miles).
Explanation:
Answer:
Average atomic mass = 21.38 amu.
Explanation:
Given data:
Mass of first isotope = 21 amu
Abundance of first isotope = 62%
Mass of second isotope = 22 amu
Abundance of second isotope = 38%
Average atomic mass = ?
Solution:
Average atomic mass = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) / 100
Average atomic mass = (62×21)+(38×22) /100
Average atomic mass = 1302 +836 / 100
Average atomic mass = 2138 / 100
Average atomic mass = 21.38 amu.
