it is a Eukaryotic cell (B)
by process of elimination we can limit it down to B and D, a prokaryotic cell would look nothing like this so therefore it is B
I think yes, because long ago, we didn’t know that. So, so many children knowing simple information, that even some adults didn’t know long ago, is evolution I’d say.
C. the media around the Staphylococci colonies turns yellow
An example of a selective and differential medium is the Mannitol Salt Agar (MSA) .
The acidic byproduct of the fermentation of mannitol, causes the phenol red component in the agar to turn yellow.
Staphylococcus aureus though pathogenic will ferment mannitol.
Sediment discharge was historically approximately 270 million cubic meters/year of suspended load and 130 million cubic meters/year of bedload. This has decreased 80% since 1850 and can be divided into three periods: historical period (pre 1900), pre-dam period (1932-1952), and post dam (1963-1982). Suspended sediment loads declined 43% between the historical and pre-dam and 51% from pre-dam to post-dam periods. The size of sediment also decreased drastically including a 72% decrease in the sand fraction. Most of this is due to dams on the tributaries acting as sediment traps primarily for the coarser sediments. Large-scale land clearing for agriculture contributed to increased sediment loads in the historic period.
Answer: The correct answer for the fill in the blank is families.
There are eight hierarchical categories used to classify organisms. Order is one of the hierarchical categories used in classifying organisms. It is subdivided into several families. It means that families occupy lower place in the taxonomic categories.
Example- Grasses belong to the order Poales and it belongs to one of its families, which is called Poaceae.
