Answer:
White blood cells change their shape to reach a site of infection.
Explanation:
White blood cells (leukocytes) are part of the immune system and have are responsible for tracking and killing pathogens such as bacteria. An important way white blood cells eliminate pathogens is by 'eating' them (pahgocytosis).
White blood cells circulate in the blood stream, but are usually required at the site of infection inside tissues. For this to happen, the white blood cells have to migrate through the walls of small blood vessels and have to be able to find their way in tissues . This can only occur because the white blood cells are able to change shape .
Answer:
changed to ammonia (NH3) by bacteria in the soil and attached to the roots of legumes (peas, beans, peanuts and soybeans). A few plants can use ammonia but most cannot. Through the process of nitrification, this problem is solved. Nitrifying bacteria change the ammonia in the soil to nitrites and then into nitrates.

Risk factors of influenza transmission in households

<span>>Reasons for increased transmission from children
</span> The research pointed three causes.
1. Children are more exposed to different people in different places. their households, peers in schools and other children.
2. Children especially preschools are said to have lower immunity which makes them prone and catching influenza.
3. Lastly, viral shedding among children can alleviate and spread period of infection.
