I think this is the answer Incineration, but i hope this helps
The best and most correct answer provided by the question is HBr, the most powerful and dangerous acid. I hope my answer has come to your help. hope this helps and have a nice day!
Answer:
A protein kinase is an enzyme which catalysis the phosphorylation reaction.
The phosphorylation can either activate or deactivate other proteins or receptors.
A protein kinase cascade refers to the series of events in which a chain reaction of phosphorylation takes place by which thousands of proteins are phosphorylated.
It helps in signal transduction through which signals (usually hormone) from outside the cell are amplified and transferred to the target molecule present inside the cell.
For example, tyrosine kinase cascade.
For the first question, a unicellular eukaryote with autotrophic features (meaning it can produce its own food) will be from either Domain Bacteria and Domain Eukarya, but since Domain Bacteria is not in the choices, then Domain Eukarya is the answer. Domain Archaea are yes, unicellular organisms, but they are not eukaryotes and they do not possess autotrophic features. Domain Eukarya have photosynthetic protozoans (i.e. Diatoms).
For the second question, in Kingdom Fungi, you chose that fungi can either be unicellular or multicellular, which is true, for instance yeast and mushrooms respectively. Fungi are heterotrophic as they cannot produce their own food. The other answer is that fungi are eukaryotic organisms since their cells have a true nucleus and they belong to Domain Eukarya.
For the third question, in Kingdom Protista, you chose that protists can either be unicellular or multicellular, and this is true in the case of amoebas and kelp respectively. Protists can be both heterotrophic and autotrophic. The other answer is that protists are eukaryotic organisms since their cells have a true nucleus and they belong to Domain Eukarya.
The answer would be a diploid cell as two haploid sex cells forms a zygote which is diploid from the two parents
