Well for one thing water wouldn't collect in drops. It also would affect pretty much everything that lives in or on water. For example there are kinds of bugs that use the surface of the water to stand on and lots of other organisms that use surface tension for their own benefits. Hope this helps!

I think the answer is a and d
Explanation:
Answer:
A) Dendritic cells and macrophages, although they are also found in other cells that belong, or not, to the immune system.
B) The innate immune response
Explanation:
The immune system is equipped with specialized receptors for the detection of pathogens such as bacteria or viruses, which are called receptors that recognize patterns (PRRs). These proteins are a key element in the innate system and are expressed primarily in antigen presenting cells, such as <u>dendritic cells and macrophages, although they are also found in other cells that belong, or not, to the immune system.</u>
<u>
The innate immune response</u> begins with the recognition of highly conserved molecular structures and present in large groups of microorganisms called 'molecular patterns associated with pathogens' (PAMP). This recognition is done by the 'pattern recognition receptors' (RRP) of the host.
The best known bacterial PAMPs are:
Lipopolysaccharides (LPS)
Peptidoglucan
Lipoteic Acids
Mananas (Mannose
)
Bacterial DNA
Double stranded RNA
Glucans
These PAMP are essential for the survival and pathogenicity of bacteria.
Water projects are typically evaluated using benefit cost analysis. Ecosystem services are the direct and
indirect benefits that people obtain from ecosystems. Many of these benefits are ignored in benefit
cost analysis, because of the absence of markets and the limited information or understanding of how
the benefits from ecosystem services are produced.
