What type of immune response would occur if bacteria invaded your lymph?
Since the bacteria has already invaded your body, the second stage of defense is required. The lymphocytes will engulf the bacteria and digest it using lysosomes. When the bacteria is gone, fragments of the bacteria are left behind by the lymphocyte to allow some T-cells to identify the bacteria's antigen.
Why do you think nitrification requires two different types of bacteria?
nitrification is a 2 step process the first step is the oxidation of ammonia into nitrate the second step is the oxidation of nitrate into nitrite since these are 2 separate steps, there is no microorganism in existence that can carry out both steps instead, the first step usually uses Nitrosomonas or Nitrococcus bacteria the second step usually uses Nitrobacter bacteria
When does the bodys second line of defense come into play?
when it gets past the first line (the skin)
Are phagocytes part of the second line of defense against microorganisms?
yes
Which cells phagocytize an antigen?
They are "phagocytes." Phagocytes include cells called neutrophils, monocytes, macrophages, dendritic cells, and mast cells. NEUTROPHILS - first line of defense mechanisms. MACROPHAGES - second line of defense mechanisms. Phagocytosis is a process by which macrophages (a type of white blood cells) engulf pathogens and cell debris.
What process occurs when an object vibrating at or near a resonant frequency of a second object causes the second object to vibrate?
resonance
What does the second stomach of a cow do?
The rumen, regarded as the second stomach of a ruminant's digestive system, is responsible for the fermentation process of digesting forage. It houses colonies of protozoa and bacteria which aid in this fermentation process.

What is the first line of defense against infection?
Your skin,sweat,mucus,and tears is the first line of defense of your immune system. it is the original protector from bacteria and viruses
Second line of defense against microorganisms?
The Second Line of defense is mainly called the Inflammatory Response. Some may say the immune response is the second layer too. The Second Line of Defense also includes leukocytes such as macrophages.
What is bodies second line of defense against pathogens?
the body's second line of defense against pathogens is the B cells.
What cycle occurs in the aquarium?
Nitrogen Cycle occurs in the aquarium.Fish produce ammonia which is toxic. In a well established aquarium, Some beneficial bacteria will break down the ammonia into nitrite, and a second species of bacteria will break down nitrite into less harmful nitrate. The whole process of converting ammonia into nitrite and then into nitrate is called nitrogen cycle.Although, only well established fish tanks have this nitrogen cycle going normally.For new aquariums, fish keepers must do fishless nitrogen cycle before they add any fish at all, or the fish will risk dying to ammonia poisoning due to insufficient amount of good bacteria. The whole fishless nitrogen cycle process can take 6~8 weeks.
What is first line of defense and what is second line of defense?
skin and mucous membranes first line of defense second line-leukocytes and macrophages, inflammation and fever third is immune system
What best describes the human body's defense mechanism against environmental bacteria?
The first line of defense is the skin, or epithelium; anti-microbial chemicals in the tears and saliva; mucus and cilia in the nose and throat; the formation of scabs after getting a cut. The second line of defense is the immune system, including interferons, antibodies, lymph nodes, and various white blood cells.

How does the third line of defense come into play?
when the first and the second lines of defense have already been overcome.
