Answer;
-Hot desert biome
Explanation;
Hot Desert is characterized by very little rainfall or a lot of rain in a very short period. The soils are often salty because minerals do not get washed away. Thus, the climate is characterized by a very little precipitation.
-Plant adaptations: There are few plant species. these plants are adapted to resist drought and store water. For example; Spiny cacti that have thick, fleshy stems that conserve water are common. Their roots extend metres away from the plant to absorb water. Other plants have small, thick, waxy leaves that also store water. Many plants have spines or produce chemicals that protect them from being eaten.
Answer:
The correct answer is both involve moving substance across the membrane.
Explanation:
Passive transport is one of the most important membrane transport process which helps in transport of polar molecules and gases along their concentration gradient across the plasma membrane.No addition energy is required to carry out passive transport because during passive transport molecules move from high concentration region to the region of low concentration.
Active transport is a specific type of membrane transport process which helps in the passage of ions against their concentration gradient across the plasma membrane.As the ions are moving against their concentration gradient additional chemical energy is required to carry out their uphill transport.
