Answer:
A
Explanation:
There are different mechanisms for transport of molecules across the cell membrane. One kind of this transport is facilitated diffusion, this is a form of passive transport, not requiring any ATP (the opposite would be active transport, where it does require ATP.
Simple diffusion does require special transport proteins, and neither does osmosis. Filtration is a technique used for sterilisation of water, where any impurities can be drawn out of the liquid
Answer:
* Glucose may cause an increase in bacterial growth - HYPOTHESIS
* The bacterial colonies grown without glucose don’t have capsules around their cells - OBSERVATION
* Bacterial growth in the glucose environment increased rapidly and then stopped after some time - OBSERVATION
* Increased glucose may lead to capsule formation in bacteria - HYPOTHESIS
Explanation:
In an experiment, a HYPOTHESIS is a predictive and testable statement that aims to answer a scientific question while an observation is made based on the results obtained.
According to this question, Annie wants to study the effect of glucose on bacterial colonies. She conducted the experiment by growing two colonies of bacteria - one with glucose present in the environment and one in an environment without glucose. Based on this experiment, the following statements are categorized as:
- Glucose may cause an increase in bacterial growth is a HYPOTHESIS
- The bacterial colonies grown without glucose don’t have capsules around their cells is an OBSERVATION
- Bacterial growth in the glucose environment increased rapidly and then stopped after some time is an OBSERVATION
- Increased glucose may lead to capsule formation in bacteria is a HYPOTHESIS
