Answer:pre-formed structures and chemicals, and by infection-induced responses of the immune system.
Explanation: brainliest?
The exoskeleton of an arthropod is chitin.
The answer is benedict’s reagent. Benedict’s
test is used to detect reducing sugars in solution when heated. The color
change occurs from clear blue to a brick-red precipitate in the presence of the
reducing sugars. The cupric compounds in
the benedicts reagent react with the reducing sugars (enediols) produced from
heating of the reducing sugars in the presence of an alkali. Benedict's reagent is comprised of a mixture of sodium citrate, sodium carbonate, and
copper(II) sulfate pentahydrate.
Answer:
Some viruses are hard to treat because sometimes it’s not the virus that makes us sick; it’s our immune system.
Explanation:
Answer: two types of macromolecules: nucleic acid and protein
Explanation:
Chromosomes particularly eukaryotic chromosomes are made up of nucleic acids in particular DNA (deoxyribonucleic acid) and some proteins which include histone proteins and non histone protein that helps in the packaging of an almost 2m DNA into a very tiny 0.6microm nucleus. The histone protein includes H2A, H2B, H3, H4 which forms an octamer around which the DNA is wrapped (structure of a nucleosome) and linker histone H1 joined to a linker DNA that links two nucleosomes.
