First, waste matter wouldn't decompose and add nutrients to the ground. then all the dead plants and animals would build up until all the nutrients had been taken from the ground because it couldn't be replenished. then the herbivores would starve followed by omnivores and carnivores. Everything would die out eventually.
Answer:
Cell adhesion molecules would help white blood cells to stick to the wall of the blood vessel, so they can permeate across the wall and go into the underlying injured tissue.
Explanation:
The cell adhesion molecules, also called CAMs, are a type of cell adhesion proteins on the cell's surface, they take part in the binding of other types of cells and work together with the extracellular matrix in the process of cell adhesion.
Long story short, the protein helps cells stick together or to the surrounding tissues, thus helping on the maintenance of tissue structure and function. In fully grown mammals (including humans), CAMs play an important and key role in creating force and movement, thus assuring the organs are able to execute their function.
In their role as "molecular glue", CAMs are important participants in the cellular mechanisms of growth, contact inhibition, apoptosis and diapedesis, and when their behavior goes haywire, they are associated with afflictions going from frostbite to cancer.
The correct answer is D, Hope that helps! :)
This is beneficial and is actually an adaptation of humans to climates with larger amounts of sunshine. The darker color of skin helps prevent damage such as sun burn.
DescriptionBiotic components, or biotic factors, can be described as any living component that affects another organism or shapes the ecosystem. So the answer would be 1 an 2
