BO
where temperature exceeds 1000 C
Fishes can survive even at a depth where
со
pressure exceeds 100 atm.
DO
Desert lizards have marvelous physiological
ability to survive scorching heat of desert​

Answer 1

Answer:

Explanation:

Fishes can survive even at a depth where co pressure exceeds 100 atm

Answer 2

Answer:

Concept:

Answer for this question is found by studying the fact each statement possesses.

Explanation:

• Fish in Antarctica that live in subzero temperatures have antifreezing proteins, such as glycerol or glycoprotein, which helps lower the freezing point of their body fluids and enables them to survive.
• Ancient bacteria known as archaebacteria (Thermophiles) are found in hydrothermal vents in the deep sea and hot springs. They can endure temperatures well above 100°C because their bodies have evolved to withstand such climatic conditions. Specialized thermo-resistant enzymes are present in these organisms, which perform metabolic tasks that are not damaged by such high temperatures.
• They have some biochemical adaptations, such as an ion exchange mechanism that operates under high pressure in order to reduce the pressure gradient between the body and the surrounding environment.
• Desert lizards don't have the physiological capacity that mammals do to cope with the high temperature of their habitat, but they still manage to maintain a relatively constant body temperature through behavioural means.

Hence, the statement "Desert lizards have marvelous physiological

ability to survive scorching heat of desert​" is incorrect
