Answer:
Straight line path.
Explanation:
Speed is the rate at which an object covers a particular distance. According to the question, the object was moving with constant speed, there is no change in the direction as well, This imply that the object is moving with constant velocity. No external forces applied on the object. Therefore the object is moving on a straight line path.
Answer:
A positive result.
Explanation:
Biuret test is a test performed to check whether proteins are present in a given sample or not. If the solution changes its colour to violet then it means that the sample contains proteins. If the colour is not changed to violet, then the result would be negative and protein would not be present in the sample.
Steaks contain a rich amount of protein. Hence, when Biuret test is performed for a steak solution, the results will be positive. The steak sample would change colour to violet.
Answer:
At first, we should know their molecular formula and symbol. In case of element, symbols are written. But in case of compound, molecular formula is used. Also we should know their coefficient (number) to make the number of atoms either side equal.

Answer:
Airways diameter can influence the airflow resistance.
Explanation:
Airflow resistance follows the same principle followed by the airway resistance. This is the resistance offered during the pulmonary blood flow.
Airways diameter affects the airflow resistance. If the diameter of airway is increased, the airflow resistance decreases and air can flow easily in the body. The decrease in the airway diameter (dilution) increases the airflow resistance of the blood artery.
