Answer:
read the explanation.
Explanation:
Both are enzymes, both has active sites because they are enzymes. A difference is that serine proteases has serine aminoacids in it active site. The aspartic proteases has an activated water molecule bond to one or more aspartate aminoacid in its active site.
Serine proteases are two main kinds, chymotrypsin and subtilisin kind. Aspartic proteases are three main kinds, pepsin, cathepsin and renins.
Serine proteases are found either in eukaryotes and prokaryotes, meanwhile the aspartic proteases are found mainly in eukaryotes as molds and yeast but rarely in prokaryotes such as bacteria.
Hope this info is useful.
Model organisms is your answer
Hope this helps : )
The answer is a. correlational research.
In this scenario, you only do observation of one event and trying to find a link between them. This method is good for finding correlation, but not for causation.
Because you only observe the subject without intervention, it shouldn't be experimental research. What you observe is only one condition, so there is no control subject that get different condition.
Answer:
DNA
Explanation:
Experiments such as the one by Frederick Griffith in 1928 showed that DNA is the hereditary molecule. How showed that virulent bacterial species could transfer DNA to avirulent species and make them virulent too. This means that DNA determines the characteristic of the individual and can be passed down or across generations.
Answer:
Fungal cells differ from mammalian cells in that they have cell walls that are composed of chitin, glucans, mannans, and glycoproteins. Both mammalian and fungal cells have cell membranes; however, they differ in their lipid composition.
Explanation: Like plants and animals, fungi are eukaryotic multicellular organisms. Unlike these other groups, however, fungi are composed of filaments called hyphae; their cells are long and thread-like and connected end-to-end, as you can see in the picture below.
