The answer is T, True. Secondary pollutants are pollutants that we do not directly release, but that are created as a side effect of releasing primary pollutants, such as carbon dioxide, sulfur oxides, and particles such as ash and dust. Secondary pollutants include acid rain, ozone, smog, and CFC's (chlorofluorocarbons).
False , as with deer , a buck has antlers , and a doe has no antlers
The answer is C the moon is between the earth and sun
During infection with Listeria, an intracellular bacterium, APCs will present antigen on MHC II molecules and triggers a phagocytic property by stimulating the release of macrophages.
What is the role of macrophages in Phagosomes?
Phagosome maturation was formerly regarded to be a very simple notion that described how much phagosomes had united with lysosomes.
- Unfortunately, this assumption is no longer valid because phagosomes are now known to interact with a variety of intracellular organelles during their maturation process.
- Proteins, such as the NADPH oxidase complex that creates the superoxide burst, may be seen being assembled on the phagocytic cup even before they are fully formed.
- When the phagosome closes and the maturation process begins, it becomes increasingly acidic and hydrolytically active, and it transiently fuses with the recycling endosomal system, the secretory system, including secretory lysosomes, multi-vesicular bodies such as the MHC class II (MIIC) compartment, and even the endoplasmic reticulum.

An elephant's trunk evolved in order to be able to stuff in and eat as much food as it can to become the big animal it is today.
The elephant's ancestors were small and had a short nose. As it turns out, the larger body size the elephant has, the more chance it gets to survive and pass on its genes to the next generation. In order to gain a larger size, it needed to eat more and be able to reach more food. Of course, its small nose wasn't capable of doing that at the time. So, through natural selection, eventually the elephants that were bigger, had longer trunks, and therefore ate more, were more likely to pass on their genes to the next generation than their smaller counterparts, and therefore with each generation elephants got longer trunks.
