The best answer is B.
The cells of a multi cellular organisms are called eukaryotic cells and have:
1. a membrane-bound nucleus
2. numerous membrane - bound organelles including the endoplasmic reticulum, Golgi apparatus, chloroplasts and mitochondria.
3. several rod-shaped chromosomes.
Because a eukaryotic cell's nucleus is said to be surrounded by a membrane, it is said to have a true nucleus. Organelles (meaning "little organ") have specialized cellular roles just like the organs of the body have specialized roles.
Answer:
your body tends to shut down
Explanation:
as blood flow to the heart decrease that means your body is either shutting down its clogged or it is a blockaged
I think one major difference with that is that animals can move around, go distances in search for food or mate, and thus make the animal densities per geography vary greatly. Birds migrate regularly, so their population densities tend to vary with seasons. Their mobility also depends on the availability of food, so animals go away if there are no food in the area.
Plants on the other hand don't move around faster (they can migrate by reproduction: it's their seeds moving around). Thus their densities tend to be more constant per season/life cycle.
Answer: Commensalism
Explanation: Well you can already eliminate parasitism because that is when an organism leeches off another. Mutualism is when one organism needs to depend on another compared to A where both are benefited. Then you can eliminate d because competition is when two organism compete with each other for survival not benefiting them both.
