Generally, you can calculate it with this formula: df = (r-1)(c-1) where r is the number of rows and c is the number of columns.
Answer:
White blood cells (WBCs) are specialized to respond to antigen and produce antibodies as well as undergo phagocytosis in response to toxic stimuli.
WBCs are part of immune system and there are five different kinds with specialized features.
In order to make a cell model, it is best to use a muscle cell and a nerve cell or neuron: there are pronounced structural differences and those are present throughout animal kingdom.
Lower animals ( such as insects, worms etc. ) have different immune system, however, they do have typical neuron and a muscle cell/skin cell (fibroblast). Such cell models are likely to be easy, distinct and bring you good grades without going through much complication and confusions of various organ systems and animal mod

Answer:
RNA molecules are made of nucleotides. (Ans. C)
Explanation:
RNA, which is also known as ribonucleic acid is found in cytoplasm of the cell, and synthesized in the nucleus. It is shorter, and a single stranded molecule. It is composed of one or more nucleotides which are linked together by phosphodiester bonds.
In RNA, the ribonucleotide contains pentose sugar ribose, four nitrogenous bases (A,U,C,G), and a phosphate group. RNA plays many types of role in cells, but mainly involved in the translation process, and it's regulation which is known as protein synthesis.
Answer:
The correct answer would be - 9 hours.
Explanation:
The half life of a drug is the time that is required to decrease or reduced to one half of the its original achieved level or the highest amount previously taken. The half life of drug is also known as the time a drug take to complete its action.
At a dose of 500 mg the Fluoxitine drug would be 250 mg in 3 hour as it is given that half life of this drug is 3 hours, 125 mg in 6 hours, and in the end 62.5 mg in 9 hours.
Thus, the correct answer is : 9 hours.
