Water vapor is water in a gas state instead of a liquid or a solid.
Biodiversity hotspots are the richest and most threatened reservoirs of life on Earth. Thus, the correct option is D.
<h3>What are Biodiversity hotspots?</h3>
Biodiversity hotspots may be defined as the regions of the earth which are rich in biodiversity and possesses the following criteria:
- The area should support greater than 1500 endemic species of flowering plants or 0.5% of total plants.
- It possesses a high degree of threat, exploitation, and biodiversity.
- It must have lost about 70% of the original habitat.
- A high degree of endemism (restricted habitat).
Therefore, Biodiversity hotspots are the richest and most threatened reservoirs of life on Earth. Thus, the correct option is D.

Answer:
Physiological reactions to stress in the alarm stage include: <em>increased heart rate and blood pressure, dilated pupils, rapid and shallow breath, and increased cortisol levels.</em>
Explanation:
Hans Seyle, a medical doctor proposed a model called the General Adaptation Syndrome (GAS) to explain the effects and stages of coping with the stress. The GAS model has three stages, known as:
1. Alarm stage
2. Resistance stage
3. Exhaustion stage
The <em>alarm</em> stage is the first stage of responding to stress. During this stage, the fight-or-flight response is activated when an individual is experiencing stress. This stage involves the following physiological reactions:
1. Increased heart rate
2. Increased blood pressure
3. Dilated pupils
4. Rapid and shallow breath
5. Increased cortisol levels
Answer:
2.kinetic energy because it has the ability to take the students to school.
Explanation:
Energy of a given system due to the virtue of the motion of the given system is known as kinetic energy of the system
now we know that
so kinetic energy depends upon mass of the system and the velocity of the system.
So here since bus is in motion and moving towards the school so the bus along with all the children must have kinetic energy in it
So here correct answer would be
2.kinetic energy because it has the ability to take the students to school.
It is located in a nucleus like organelle called the nucleoid
