A student wanted to know the most effective way to grow bacteria in a lab. He conducted a descriptive investigation instead
of an experimental investigation
What is a limitation of his investigation?
O A descriptive investigation cannot show a cause-and-effect relationship between bacteria growth and possible factors
affecting growth.
O A descriptive investigation is always more expensive than an experimental investigation.
O A descriptive investigation usually does not involve much data collection to support a hypothesis.
O A descriptive investigation provides little prior knowledge or background information about bacteria growth

Juliana says that she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6: 10. which statement explains whether juliana is correct? she is correct because she can multiply 6 and 10 by any number to form an equivalent ratio. she is correct because 6: 10 can be written as 1: 2 and there are an infinite number of ratios for 1: 2. she is not correct because the multiplication table does not include multiples of 10. she is not correct because 6: 10 is equivalent to 3: 5 and there are only 9 ratios in the multiplication table that are equivalent to 3: 5.
