Which statement best illustrates a biotic or an abiotic factor that is often found in a city park?
ddd [48]

Answer:

Biotic: Plants

Abotic: Rocks

Explanation:

A biotic factor is something in an ecosystem or environment that is living. Some examples that could be found in a park are grass, flowers, trees, squirrels, pigeons, fish or people.

An abiotic factor is the exact opposite of a biotic factor: something in an ecosystem or environment that is not alive. Some examples that may be found in a city park include a park bench, a trash can, rocks, a playground, a pool, basketball court, temperature, and humidity.

Relate the development of plant needles to the occurrence of mutations.
xxMikexx [17]
<h2>Development of Plant Needles</h2>

Explanation:

  • Seed of pitch pine treated with colchicine delivered tetraploid seedlings which had thick and sporadic needles and less fortunate tallness and diameter growth than ordinary seedlings.  
  • In test of colchicine-initiated polyploidy in pines, researcher found that a significant number of the polyploid plants returned to a diploid development in light of the fact that the polyploid cells partitioned at a more slow rate and were overwhelmed by the more quickly developing diploid cells which encompassed them.  
  • The primary needles of both diploid and polyploid plants were more effective at low light intensity than secondary needles, and they had lower compensation points.

kirza4 [7]

It would not be plants, even though it has cell walls. They are not made of chitin. Plants are also not heterotrophic.

Fungi, however, decompose other matter, and have cell walls made of chitin. This would fit the description.
