Answer:
The adenosine triphosphate (ATP) molecule
Explanation:
The actin filaments are often associated with myosin to produce muscle contraction. These myosin filaments are considered to be 'molecular motors' capable of converting the chemical energy contained in the ATP molecule to mechanical energy, thereby producing cell movement. Myosin heads bind to actin filaments in order to generate a power stroke. When the adenosine triphosphate (ATP) molecule binds to myosin, the myosin head detaches to the actin filament. During this process, the ATP molecule is broken down and then the released energy is used by the myosin filament to return to its original position.
Answer:
according to ohms law v= ir so i =50/150, =0.33
Answer:
D. Several cells are in the process of dividing into two new cells
Explanation:
The universal cell theory which was proposed in 1838 and contributed by three scientists namely: Theodor Schwann, Rudolf Virchow, and Mathias Schleiden, consists of three components namely:
1) Cell is the basic and functional unit of life
2) All living organisms are made up of one or more cells.
3) All existing cells arise from pre-existing cells.
Hence, in this question involving a scientist who is observing living Cells in a Petri Dish under a Compound Light Microscope, the observation that "Several cells are in the process of dividing into two new cells" provides evidence to support one of the three components of the cell theory ( all living cells arise from preexisting cells).
"The number of chromosomes present in a diploid cell doubles for each generation because there are two parent" is the one among the two statements that <span>is the best explanation for why the chromosome numbers above are all even. The correct option among the two options that are given in the question is the second option. </span>
The plasma membrane primarily consists of: lipids, proteins and carbohydrates.
