Answer:
Macrophages
Explanation:
Macrophages can be defined as a phagocytic leukocyte that can engulf a foreign bacterium.
They are cells found in the immune system as mobile white blood cells that are usually develop in response to a dead or damaged cells and even in cases of an infection.
<h2>Genetic diversity </h2>
Explanation:
If the environment changes, the species runs the risk of not having the genetic diversity to be adaptable to that change and could go extinct
- Genetic diversity is the diversity or genetic variability within species
- The huge variety of different gene sets defines an individual or a whole population's ability to tolerate stress from any given environmental factor
- While some individuals might be able to tolerate an increased load of pollutants in their environment, others carrying different genes might suffer from infertility or even die under the exact same environmental conditions;the former will continue to live in the environment the latter will either have to leave it or die
- Any change in the environment - natural or human induced causes a selection of events that only the fittest survive
- In case of elephant seals,overhunting reduces the sum of genes available,thus leaving behind a population that is less capable of tolerating any further natural or human disturbances in environment
- The loss of genetic diversity within a species can result in the loss of useful and desirable traits
At the place marked with the letter A we have a divergent plate boundary. On this type of boundary, the plates are moving away from one another. As they move away, they leave a gap behind them, and the crust is becoming thinner and thinner with lots of cracks in it. Because of that, the high pressures from the mantle manage to push upwards the magma with ease. The magma reaches the seafloor and it is pushing the crust upwards until it breaks it. As the magma pushes the crust upwards,underwater volcanoes are formed, and when the crust is broken by the magma, the magma flows get on the seafloor, cool of very quickly in the water, and create new crust.
They are inversely related. As the distance increases the magnetic attraction decreases and when the distance decreases the magnetic attraction increases
