What behavioural adaptation does a desert fox have to help it survive in hot places
SIZIF [17.4K]
1. Their large ears help dissipate excess body heat on hot days in the desert. 2. The fennec fox seems to be the only carnivore living in the Sahara Desert able to survive without free water. Their kidneys are adapted to restrict water loss, their extensive burrowing may cause the formation of dew, which can then be consumed, and they will receive moisture from the food that they eat. 3. Their burrowing and nocturnal lifestyle helps restrict water loss. 4. Their thick fur helps insulate them from the cold desert nights. 5. Their sandy fur helps to reflect heat, and also provides excellent camouflage. 6. Fennec foxes also have thick fur on the soles of their feet, which insulate against the hot sand of the desert. This extra fur on the soles of their feet also affords them excellent traction in the loose sand.

In the cell, energy that drives endergonic reactions is often obtained from
IRISSAK [1]

Answer: B) energy released from exergonic reactions.  

Explanation:

Cell metabolism is the set of reactions that occur in the cellular environment to synthesize or degrade biomolecules to produce energy. Synthesis metabolism of biomolecules is known as anabolic (anabolism) and catabolic degradation (catabolism).

Endergonic reaction (product has more energy than reagents) and requires energy to occur. Anabolism occurs when the cell has sufficient energy or substrate. Catabolism, in turn, occurs in situations in which the body needs energy, such as between meals and fasting.

The reactions of anabolism and catabolism are opposite but occur in an articulated manner, allowing the maximization of available energy. Thus, while catabolism occurs spontaneously, an exergonic reaction with ATP production, anabolism is non-spontaneous, or endergonic, requiring energy to occur. In other words energy that drives endergonic reactions is often obtained from B) energy released from exergonic reactions.

Lower temperatures lead to slower soil formation.
MAVERICK [17]
<span>It is true that lower temperatures lead to slower soil formation. The lower the temperature in the air is, the slower the soil is going to form. In order for soil to form properly and completely, it needs to have some warmth because heat helps this process run faster. </span>
