<span>The septum is the wall that separates the left and right sides of the heart. If there is a hole in the wall between the two ventricles, it is called a ventricular septal defect (VSD).</span>
Answer:
a)
1. Tropical deserts: Hot and dry most of the year; They have a few plants and a hard, windblown surface strewn with rocks and some sand.
2. Temperate deserts: Hot in the summer and cold in the winter; There is more precipitation than tropical deserts; The sparse vegetation primarily consists of widely dispersed, drought-resistant shrubs and cacti or other succulents adapted to the lack of water and temperature variations.
3. Cold deserts: Winters are cold, summers are warm or hot, and precipitation is low; Desert plants and animals have adaptations that help them to stay cool and to get enough water to survive.
b)
Plants and animals survive because They have adaptations that help them to stay cool and to get enough water to survive
Answer:
The process that occurs in the structures marked with X is the Krebs cycle (last option).
Explanation:
The Krebs cycle is a process by which energy in the form of ATP is produced from pyruvate molecules obtained by transformation of glucose, which occurs in the mitochondria, marked with X in the diagram (see image).
The mitochondria is a specialized organelle, whose function is the production of energy within the cell. It has a membrane on the outside that allows the passage of proteins, energetic substrate and ions, and inside it crests are formed where the energetic synthesis takes place.

Answer:
When the concentration of molecules of a substance is the same on both sides of a membrane the solution is isotonic.
Explanation:
A given substance, when it has the same concentration on both sides of the membrane, is in equilibrium and the solution is called isotonic, from the extracellular space with respect to the cytoplasm.
The cell membrane is semipermeable to the passage of water and some substances. Hypertonic and hypotonic solutions tend to establish the dynamics of entry and exit of molecules or water, due to the concentration or osmotic gradients that are established, respectively.
An<u> </u><u>isotonic solution </u><u>does not generate gradients</u>, because the concentration of molecules is equal in the extracellular space with respect to the intracellular space.
