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- Unfortunately, this assumption is no longer valid because phagosomes are now known to interact with a variety of intracellular organelles during their maturation process.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.

Answer:
B) 0.25
Explanation:
In the given individual, the genotype is aaBbCc. This indicates that the individual has two pairs of contrasting alleles. Thus it will produce four different types of gametes, abc, aBC, aBc and abC will be formed. Out of 4 types of gametes only one gamete namely, aBC is with two beneficial alleles. Thus, the proportion of two or more beneficial alleles is 0.25 (1 out of 4).

Answer:
<em>Answer = explanation.</em>
Explanation:
If we think deeply about the matter, animals are way more important than humans and our needs, since nature depends on the relationship animals have with each-other and not on anything humans do. Historically, we were part of nature, but that was when we were still hunting, gathering and reproducing, not making trillions of plastic bags every year.
Natural conditions should be preserved at all costs, in other words, it comes first, and our needs should come last, in a very environmentally conscious society, that is. If we continue putting ourselves and our needs first, future generations will have a really nasty world to live in. But, since humands have their needs, we should maintain them, as long as they're within the "things I need to survive, study and work" range of needs, otherwise, we will be talking about unnecessary stuff.
