White Blood Cells Defend the Body Against Disease
Neutrophils are phagocytes, cells that consume invading pathogens. Lymphocytes, the second most common type of white blood cell, disseminate through the organs and tissues of the lymphatic system. Lymphocytes target specific pathogens as part of the immune response.
Explanation:
Forced convection may happen by natural means, such as when the heat of a fire causes expansion of air and bulk air flow by this means. The shock wave that transfers heat and mass out of explosions is also a type of forced convection.
Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.
Mantle convection is the slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface.This subjected material sinks through the Earth's interior.
Answer:
This is known as Population.
Explanation:
A population is made up of organisms of the same kind living together in the same habitat. Characteristics of a population include the population size, frequency, density, percentage cover and distribution.
Factors that dominantly affect a population comes up especially in size and distribution. These factors include; migration of organisms to other habitats, invasion or colonization by new species, increase or decrease in birth and death rates etc
