The right answer is HEPA filter.
A HEPA filter (High Efficiency on Particles Air) can filter up to 99.97% of 0.3μ aerial particles.
These filters are used to clean the air and retain suspended particles (dust, pollen, bacteria etc.) and other particles that can cause respiratory allergy in sensitive subjects.
They are very used in sterile rooms
The gradual development or replacement of one ecological community by another is called environment-replacement/takeover.
Answer;
Angiosperms are grouped into monocots and dicots.
Explanation;
-Angiosperms are vascular seed plants in which the ovule (egg) is fertilized and develops into a seed in an enclosed hollow ovary. Their ability to flower sets them apart from non-flowering plants, also known as gymnosperms, allowing them a successful means of reproduction.
-Angiosperms can be divided into two categories, Monocotyledons (monocots) and dicotyledons (dicots). This distinction is based on the number of cotyledons, the food storage structures in their seeds. Monocots have one cotyledon while dicots have two.

<em>-Lumen Learning</em>
Answer:
Density-dependent factors include disease, competition, and predation. Density-dependant factors can have either a positive or a negative correlation to population size. With a positive relationship, these limiting factors increase with the size of the population and limit growth as population size increases.
