Explanation:Myplate is a program of the United States of America, it aims to design standard nutrition required for children,it aims to ensure that the children live a healthy Lifestyle with reduced incidence of diseases.
MyPlate is managed and published by the USDA(United States Department of Agriculture) Center for Nutrition Policy and Promotion. It is a circle of very colourful and attractive food/ nutrition designs which make it more attractive and appealing.
Answer:
Adhesion and cohesion
Explanation:
Capillary action refers to the ability of water to move in small-diameter or narrow tubes against the force of gravity. Water has a tendency to form hydrogen bonds with other water molecules.
Intermolecular hydrogen bonding allows the water molecules to stick together. This tendency of water molecules to stick together is called cohesion. Adhesion is the ability of the water to stick to other substances with polar or charged groups. As a consequence of cohesive and adhesive properties, water exhibits capillary action. When water moves through microscopic spaces present between the soil particles towards the roots, it is capillary action.
c. herbivores.
b. omnivores.
d. carnivores.
a tumor–like growth
a hemorrhage
2. When a virus invades the body, some B cells recognize it as nonself and produce plasma cells that release a substance to kill the virus. What is this substance called?
antigen
antibody
pathogen
3. Which of the following forms blood clots?
fibrin
macrophages
thrombin
4. An antigen has invaded a mammal's body. Specific immune cells engulf and ingest it. Some of the digested pieces are displayed on the cells' bodies. What happens next?
B cells are activated and release antibodies.
T cells are activated and produce clones.
B cells withdraw the immune response as the antigen is killed.
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.
