Answer:
Objects able to block all the light are called opaque and will form a shadow. ... The closer an object is to the light source, the larger the shadow it casts. This is because an object closer to the source will block a larger area of the light, increasing its shadow size.
Explanation:
Answer:
The unattached microbes are moved from lungs to epiglottis by the <u>mucociliary escalator effect.</u>
Explanation:
Mucociliary escalator, also known as mucociliary clearance, is one of the major defense mechanisms that protects the lungs. It describes the self-cleaning mechanism of the bronchi which are present in the lungs. The effectiveness of this mechanism depends on the properties of the produced mucus and on the quality and number of the cilia present in the lining of the airway.
Therefore, the unattached microbes are moved from lungs to epiglottis by the <u>mucociliary escalator effect.</u>
The correct answer is: d. it contains many light-sensing columns called ommatidia
Ommatidia are units that form compound eyes of arthropods such as insects, crustaceans and millipedes (these are invertebrates) and make them very sensitive to motion. Ommatidia are composed of photoreceptor cells (visual detection) surrounded by support cells and pigment cells.
The eyes of vertebrates are more complex showing that progressive improvements in the structure of the eye occurred during the evolution.
The Outline of the top-down effects on bacteria in the four mesocosms is
- Zooplankton is bacterivores that help keep bacteria populations in Check.
- Ingestion of zooplankton by fish leads to a rise in bacteria levels.
<h3>What are
mesocosms?</h3>
Generally, mesocosms are defined as any outdoor experimental system that investigates the natural environment in a controlled setting and may be thought of as a mesocosm.
In conclusion, Overview of top-down influences on bacterial growth in four mesocosms
To put it another way, zooplankton is bacterivores that play a role in maintaining a healthy bacterial balance.
Fish-eating zooplankton may cause an increase in bacteria in the water.
