how does proper waste management help prevent pollution
Answer:
When waste is properly managed by recylcling, it does not end up in mills or habitats. Therefore it does not pollute the environment.
Plants have specialized structures that perform their necessary life functions. The gases that are crucial to proper
function within a plant are oxygen and carbon dioxide. What structure would control the exchange of these gases in
a plant?
a. mesophyll
b.trichomes
c.root hairs
d.stomata
Answer:
Stomata
Explanation:
Normally stomata open when the light strikes the leaf in the morning and close during the night.
d. During photosynthesis, CO2 enters the plant leave through opened stomata and in return it releases glucose,oxygen and some little molecules of water

What is its primary function of the structure of a plant cell?
Answer:Chloroplasts are organelles that are crucial for plant cell function. These are the structures that carry out photosynthesis, using the energy from the sun to produce glucose. In doing so, the cells use carbon dioxide, and they release oxygen.
Explanation:hope this helps
In all organisms, the cell is the fundamental unit of life. Plants, like animals and humans, are made up of multiple cells. The cell wall of the plant cell gives the cell its shape and covers the cell. Other organelles, in addition to the cell wall, are associated with various cellular activities.
What organelles are present in cell ?
Plant cells are eukaryotic cells that differ from other eukaryotic organisms in several fundamental ways. There is a nucleus and similar organelles in animal and plant cells. The absence of a cell wall outside of the cell membrane is one of the plant cell's distinguishing characteristics.The building blocks of plants are called plant cells. The primary function that plant cells perform is photosynthesis.The chloroplasts of a plant cell are where photosynthesis takes place. It is the way that plants use sunlight, carbon dioxide, and water to prepare food. During the process, ATP is produced as energy.Water and nutrients are transported from the roots and leaves to various parts of the plant by a few plant cells.A mature, higher plant's cells become specialized to carry out particular vital functions that are necessary for their survival. Some plant cells are responsible for storing food, while others transport water and nutrients.Parenchyma cells, sclerenchyma cells, collenchyma cells, xylem cells, and phloem cells are the specialized plant cells.To know more about cell check this:

what animals can be used to replace human parts?
cattle
sheep
goat
pig
Answer:
Pig
Explanation:
Pig valves are already used successfully in heart transplants. Human-to-human organ transplantation has only been around since the 1950s, and scientists have been working on animal-to-human transplants for almost that long. In the '60s, Keith Reemtsma experimented with transplanting chimpanzee kidneys into humans.
Answer:
Pig
Explanation:
This process is called Xenotransplantation. The animal organ, probably from a pig or baboon could be genetically altered with human genes to trick a patient's immune system into accepting it as a part of its own body. (Wikipedia)
