Answer:
The main components of the cytoplasm are cytosol (a gel-like substance), the organelles (the cell's internal sub-structures), and various cytoplasmic inclusions. The cytoplasm is about 80% water and usually colorless.
Answer:
The correct answer is the neurotoxin known as tetanospasmin toxin.
Explanation:
Tetanus is a disease caused by a bacteria known as clostridium. The bacteria are found in soil, manure, dust, and saliva. It can enter the host body by a cut or rusted or dusty nail or burn. It causes muscle spasm or jaw locking or bone locking.
It releases the neurotoxin that is tetanospasmin toxin that inhibits the secretion of γ-aminobutyric acid (GABA) and results in a variety of symptoms associated with tetanus.
Thus, the correct answer is the neurotoxin known as tetanospasmin toxin.
Develop hypothesis. You need something to test, and you need to prove what you think is going to happen, in order for that to happen you need to come up with what you think is going to happen based on your previous experience ect.<span />
Answer:
Furthermore, what kingdoms have no cell walls? Protists that are similar to animals do not have cell walls at all. Plant- and fungi-like protists have cell walls that are similar to plants. Other protists have a unique cell wall that is different from cell walls seen in other eukaryotic kingdoms.

Answer:
Operons afford the organism the opportunity to simultaneously regulate transcription of multiple genes, whose products are active in the same process.
Explanation:
Operon is the group of related genes and the operator and promoter sequences that regulate their expression. All the genes in an operon are expressed together and are under the regulation of the same promoter and operator sequences.
Operons consist of the genes that are involved in related metabolic pathways. For example, the genes that code for the enzymes of lactose catabolism are expressed together as lac operon. It allows simultaneous expression of the genes of lactose catabolism only when lactose is present in the medium. Similarly, these genes are inhibited simultaneously in absence of lactose by binding of repressor protein to the operator sequence.
