Immediately, the pathogen has been recognized:
Macrophages acts as the first line of defence by engulfing pathogens identified by antigens which will now present the antibody shape to a helper T cell.
The Helper T cells produce a signal to plasma and Memory B cells to yield antibodies that attach to the antigens. The cytotoxic cells that leads to cell death are activated by the helper T cells.
Antibodies helps to immobilize pathogen for macrophage to feed on.
if the pathogen comes back a 2nd time the memory cells helps in quick and efficient recovery by producing the specific B and T cells for the antigen.

Answer:
Plastic wrap is commonly made out of PVC (Polyvinylidene Chloride). In recent years other PVC alternatives have become more popular. The most popular option in recent years is LDPE (Low-Density Polyethylene) because it is considered to be safer for the body. The best management for plastic wrap would have to be by you taking plastic wrap to local retail stores where they collect plastic grocery bags for recycling. Any package that you see with the How2Recycle Store Drop-Off label can be recycled this way.
Human waste from excretion is probably classified as organic waste, since it comes from you and the food you eat. The best management for human excretion would probably be sewer pipes that lead into the sewage system that lead into other mainframes.
Wastewater is an odd typing since it contains human waste, food scraps, oils, soaps and chemicals. The best management for this would include physical water treatment, biological water treatment, chemical treatment, and sludge treatment.
5. Design an experiment that
determines the symbiotic relation-
ship between a sloth, which is a
slow-moving mammal, and a species
of green algae that lives in the
sloth's fur.
Explanation: this experiment is long term which means patience is compulsory. you need to have a wild sloth and a domesticated sloth adopted right at their birth (he should be in a controlled environment that mimics the wild). your domesticated sloth shouldn't have the algae. at their middle age, you should compare them with them from every aspect.
you can always tell the genotype by looking at the phenotype. true or false?
in the adult digestive tract, where do lipases break fat into fragments so that it can be absorbed into the lymph?
As to the digestive tract, the function of the lipases would take place in the small intestine.
Lipase is an enzyme that helps us to metabolize fat. It does this through hydrolysis. Although in reality, as an enzyme, its main function is to catalyze this process. Lipases are the subclass enzyme of the esterases.
Lipases are necessary for the proper digestion and transport of fats in the form of lipids. They are also essential to process these lipids in the human body. This enzyme is present in most living organisms outside of humans.
Although lipase enzymes are produced throughout the body, the bulk of lipase production occurs in the pancreas. It will then travel to the small intestine to carry out its functions in the digestive tract.

In the adult digestive tract, lipases in the small intestine break fat into fragments so that it can be absorbed into the lymph.
Fat digestion occurs efficiently and almost completely in the small intestine by pancreatic secretion of lipases.
Pancreatic lipase acts on triacylglycerides to give free fatty acids and monoacylglycerides.
First, they are absorbed by the epithelial cells of the intestinal wall called enterocytes, creating complex particles called chylomicrons, loaded with triglycerides.
Fatty acids are re-esterified within the enterocyte and enter circulation through the lymphatic pathway as chylomicrons.
Chylomicrons bind to lymph, which carries them to the bloodstream, this indicates the great importance of lymph in the process of assimilation of dietary fats.
Therefore, we can conclude that in the adult digestive tract, lipases in the small intestine break fat into fragments so that it can be absorbed into the lymph.

2. A volcano erupts 40 miles from an owl’s ecosystem. Ash from the eruption blocks sunlight over your ecosystem for several (7-10) months.
a. Explain what happens within the food web in the weeks that follow the eruption.
b. The ash clears and several more months go by. What do you think will happen to your ecosystem?
Answer:
a. Sunlight cannot penetrate through the ash clouds. thus photosynthesize won't occur. so the food chain will begin to collapse from the producer and primary consumer. owls will be out thinking that it's night. they will catch fish resulting in an imbalanced ecosystem. the aquatic population will decrease. then it's the doom days for owls. they will emigrate or will die.
b. the ecosystem will restore. that's how nature works.
The volcanic eruption destroyed the owl ecosystem because it prevented the sun's light from entering, so the food web of the ecosystem was destroyed because there was no food, and a new ecosystem will grow after many months.
What is the ecosystem?The ecosystem has both biotic and abiotic components, and there are many food chains and food webs present in the ecosystem, so the volcanic eruption harmed the ecosystem and killed the populations present, but after many months, when the ashes from the volcanic eruption are cleared, a new population will grow and a new community will be seen.
Hence, the volcanic eruption destroyed the owl ecosystem because it prevented the sun's light from entering, so the food web of the ecosystem was destroyed because there was no food, and a new community will grow after many months.

Suppose you remove the rabbits, grasshoppers, birds, and mice ( the herbivores) from a food web that also includes grass, mushrooms, lizards, and hawks. Which organisms would be affected and how?
If you remove the herbivores from a food web that also includes grass, mushrooms, lizards, and hawks, the organisms that would be affect are lizards, and hawks.
A food web shows all the possible feeding relationships in an ecosystem. Recall that there is an interconnection between organisms which involves exchange of matter and energy through feeding relationships.
In the food web, the grass is the producer, the herbivores are the primary consumers and the carnivores are the secondary consumers. These secondary consumers eat the primary consumers.
Lizards eat grasshoppers and hawks eat birds. When these are removed from the food web, the Lizard and Hawk are most affected because they will starve owing to lack of prey.
