B: Antigens

Explanation: Antigens itself are the invaders that causes an infection or a disease in living organism. They do not protect against invaders in non-specific response as they themselves are the ones who are invading the body.

Digestive enzymes are the enzymes that act on a particular substrate for its action at a particular PH.  

Stomach acid is the hydrochloric acid that keeps the PH of the stomach low and prevents the growth of unwanted pathogens.

Lysosomes have digestive enzymes in it. It performs the process of phagocytosis.

Please help me. I been stuck on this question for a long time :(​

Answer:

Explanation:

1. Climate change is caused by changes in the earth's atmosphere in the amounts of greenhouse gases released into the air. Some scientists believe that 100% of global warming is due to humans. The largest contribution comes from burning fossil fuels because it releases carbon dioxide gas to the air, which is done by humans. Other factors that contribute to climate change include:

>Deforestation- clearing out trees affects wildlife, ecosystems, whether patterns. Forests cover 30% of the lands mass and clearing them leaves many animals without homes.

>Waste from factories- they release tonnes of toxic fumes into the air.

> Agriculture and farming- this is a surprising contributing factor to global warming. Animals produce a greenhouse gas called methane and when livestock are grazed at a large scale, the amount of methane produced is a big contributor to global warming.

     Some fertilizers release nitrous oxide, which is another greenhouse gas.

2. The effects of global warming include:

    >Melting glaciers- this leaves many animals without homes and it also causes a rise in sea levels which causes flooding. (that's 3 effects)

    >Worsening droughts- this leaves many humans to die as they have no food or water.

    >Increasing tornadoes

okay that's all i could do... hope it helps.

If you are performing this test on an unknown organism why is it a good idea to run simultaneous
AlexFokin [52]
The question seem to be incomplete but I found the complete question which is:
If you are performing this test on an unknown organism, why is it a good idea to run simultaneous tests on known phenylalanine-positive and phenylalanine-negative organisms?

Here is the Answer:

Inoculation of a positive control and success from it includes certainty to negative outcomes on an unknown organism. That is, you know the test is working effectively, so the negative outcome is most likely precise. Without the positive control, there is dependably a component of uncertainty whether the negative outcome is a genuine negative or a false negative. performing the test on a known phenlalanine-negative organism is valuable in that it exhibits what a negative outcome looks like.
