NeTakaya

Answer:

The cell with chloroplasts, abundant ribosomes, plus an endoplasmic reticulum, and a cell wall is of the plant cell type.

Explanation:

Plant cells are eukaryotic cells found in all plants, with specific characteristics given their ability to be autotrophic and use solar energy to synthesize their nutrients. The presence of many ribosomes and a developed endoplasmic reticulum is due to their high capacity for plant protein synthesis.

One characteristic that differentiates plant and animal cells is the presence of a cell wall, which surrounds the cell membrane, and chloroplasts. Chloroplasts are responsible for making the process of photosynthesis possible.

What is the benefits of recycling plastic and paper products to wildlife?
polet [3.4K]

Answer: The correct answer is A) fewer landfills.

When plastics and paper products are dumped in the landfills, they can cause harmful impacts to the wildlife. This is because chemicals like ammonia and bleach ( present in the landfills) can produce toxic gases and when wildlife tries to consume them, this can harm their health.

If paper and plastics are recycled, it will result in fewer landfills.
