What do you understand by frequency and time? Frequency is the number of occurrences of a repeating event per unit of time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. The period is the duration of time of one cycle in a repeating event, so […]

The intense sun and warm water of the equator heats the air in the ITCZ, raising its humidity and […]
How do different amino acid sequences affect organisms?
How do different amino acid sequences affect organisms? The outcome of a frameshift mutation is complete alteration of the amino acid sequence of a protein. Consequently, once it encounters the mutation, the ribosome will read the mRNA sequence differently, which can result in the production of an entirely different sequence of amino acids in the […]
What is the acceleration of a falling object?
What is the acceleration of a falling object? 9.8 m/s/s What is acceleration of free fall on Earth? An object that is moving only because of the action of gravity is said to be free falling and its motion is described by Newton’s second law of motion. The acceleration is constant and equal to the […]
What causes change to ecosystems?
