Answer:
b) contact transmission.
Explanation:
Contact transmission of pathogens occurs directly or indirectly between the source of the pathogens and the host organisms. During contact transmission by droplet spread, the pathogen is carried on smaller particles. These particles move through air for a very short distance, usually less than a meter. Therefore, droplet transmission of a pathogen requires that the source and host are present in close proximity.
Carbon, hydrogen, oxygen, nitrogen
Answer:
Global climate models usually work by managing the planet as a set of connected boxes because this facilitates the management of the calculations applied in a climate system that is dynamic, variable and complex, which is due to the fact that there is not an equal pattern of climate in each area of the planet.
Explanation:
Climate models have been designed to show the dynamics of the planet's climate and what can be expected from the changes that occur in the future.
The scientific basis of a climate model is physical phenomena and chemical reactions to which a series of differential calculations are applied to determine the behaviour of:
- <em>Winds.</em>
- <em>Temperature.</em>
- <em>Relative humidity.</em>
- <em>Rainfall.</em>
- <em>Pressure changes.</em>
- <em>Heat transfer.</em>
- <em>Hydrological dynamics.
</em>
Global climate models usually divide the planet into sections -such as boxes- making the calculations in each sector, as well as the interaction of each section with the adjacent sections, which greatly facilitates making the differential calculations, showing the climate at a given time and making predictions of future climate behavior.
It is important to mention that a climate model also explains the changes that occur in the climate due to human activity, which is different in each region of the world.

According to the endosymbiotic theory of the origin of both chloroplasts and mitochondria, the ancestors of these two organelles were free-living prokaryotic cells. This theory states that an early eukaryotic cell engulfed a prokaryotic cell by endocytosis, much as one of our phagocytic white blood cells engulfs a bacterium.
During the process of photosynthesis<span>, plants use energy from the Sun to convert carbon dioxide and water into glucose and oxygen. </span>These products<span> are, in turn, used by the plant or animals that eat the plant during cellular respiration to produce ATP. So it would be Carbon dioxide. Hope this helps. :)</span>
