Answer:haemoglobin
Explanation:
Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called haemoglobin in the red blood cells then carries the oxygen around your body.
Answer:
Reproductive cells have half the amount of chromosomes than body cells
Explanation:
I think that you are talking about body cells when you say "most cells in an organism." If that is the case, then the reproductive cells, sperm and egg cells, have half the amount of chromosome than body cells.
For example: Human body cells have 46 chromosomes. Human reproductive cells has 23 chromosomes.
In sexual reproduction, each parent gives 1/2 of a full set of chromosomes to create the full set needed for an organism.
I think it's the simple columnar epithelium.
The most familiar non-vascular plants that contain simple conducting cells are Mosses. Most non vascular are bryophytes and are small in size, they lack vascular tissues and also lack true leaves, seeds, and flowers. Instead of roots, the have hair-like rhizoids that functions to anchor them to the ground and to absorb water and mineral salts from the soil. They are three types, mosses, hornworts and liverworts.
Answer:
Stop habitat destruction
Explanation:
Cutting down and burning forests basically take away the shelter, hunting grounds, and overall habitat away from many species that use the trees as a form of shelter and protection. Removing their shelter, which could be their only form of protection causes many of these organisms to die, not to mention the plants that are necessary to keep the food chain balanced.
