1) pathogen enters body and releases chemoattractants
2) a phagocyte/macrophage is attracted by these chemicals
3) the phagocyte engulfs the pathogen using its pseudopodia
4) the membranes of both organisms fuse forming a phagosome
5) lysosomers in the phogocyte fuse with the phagosome, forming a phagolysosome
6) these enzymes digest the pahogen (hydrolyse the bonds)
7) the antigens of the pathogen are placed on the surface of the phagocyte making an APC (antigen presenting cell)

Dementia
Explanation:
Dementia is a condition that involves impaired mental ability and memory which is common among older adults. This condition, which is a major contributor to disability and placement of older adults in nursing homes, can be as a result of several factors of which nutrition has a major role to play. Metabolic and endocrine problem that results to the inability of the body system to regulate nutrients such as calcium and vitamin B-12, are some of the factors that triggers dementia in older adults. Also, nutritional deficiencies such as dehydration, inadequate intake of vitamin B-1, vitamins B-6, copper,vitamin E, and vitamin B-12 increases the chances of developing dementia in older adults.
Research shows that low levels of vitamin D can be linked to increased risk of developing dementia, and as such, supplements such as B-complex vitamin, vitamin C, and vitamin D is usually recommended for the prevention of dementia, especially when they are deficient in the diets taken.
Answer:
Autotrophs
Explanation:
Food chain is a step by step feeding process in an ecosystem where an organism producer is been feed on by another organism that depends on it
called consumer and it is also feed on by predator. Producer usually produce their food its includes plants, Algae, phytoplankton.
The energy level moved from the producer to the last organism on the chain.
Autotrophs are the same as producer and an Algae food chain is an example of aquatic food chain where algae serves as primary source of energy(Producer) and its been feed upon by mosquito larvea and larvea by frogs and frogs are eaten by racoon.
