The conditions described by Mike all point to an inflammation, not a tumor-like growth or hemorrhage. When a body is invaded by a virus, B cells produce antibodies to destroy it. Fibrin is responsible for blood clot formation. When pieces of a digested antigen are displayed on a cell's body, it prompts T cells to activate and produce clones.
1. Mike's knee injury which revealed a red, swollen, and warmer area than the surrounding indicates an inflammation. This is a protective response to injury or destruction of tissues which serves to destroy, dilute, or wall off the injurious agent and the injured tissue.
2. When a virus invades the body, some B cells recognize it as foreign and produce plasma cells that release a substance to kill the virus. This substance is referred to as an antibody.
3. Fibrin is responsible for the formation of blood clots. It is a fibrous protein that helps control bleeding and forms a meshwork at a wound site, creating a clot to prevent further bleeding.
4. When an antigen invades a mammal's body, specific immune cells engulf and digest it. The digest pieces are displayed on the cells' bodies leading to the activation of T cells which then produce clones.

Answer:
The blue whale is very genetically diverse. There are four subspecies of blue whale: B. musculus musculus, B. musculus intermedia, B. musculus indica, and B. musculus brevicauda. Very little is known about the genetic differences between these species besides appearance and weight. The subspecies don’t usually mix because of location.
In the 19th and early 20th centuries, almost all of the blue whales were killed for their baleen plates. They are now increasing in population, and scientists would like to try to see what they can do to continue to increase the population.

Answer:
Protists are said to be the most diverse of all eukaryotic kingdoms because the organisms in the Protista kingdom are eukaryotic organisms that are not plants, animals, or fungi.

Please help.
Answer:
The petals of a flower are usually brightly colored to attract pollinators such as bees, butterflies and hummingbirds. The stamen is the small body that holds and produces pollen. The pistil is the ovary of the flower. Ovules are the egg cells of a flower, which eventually become seeds.
chemical signals, synapse, neurotransmitters
synapse, electrical signals, chemical signals
synapse, electrical signals, neurotransmitters
Answer:
The correct answer is synapse, electrical signals, neurotransmitters.
Explanation:
Neuron communicates with other neurons via action potentials and chemical neurotransmitters through the synapse.
Two neurons form a junction that is termed as a synapse, there an action potential that results in neuron A to release a neurotransmitter (chemical).
Synapses are thought of as the site of converting an electrical signal into a neurotransmitter release which is a chemical signal.
Thus, the correct answer is synapse, electrical signals, neurotransmitters.
