Lynna [10]3 years ago

As a society, we depend on healthy ecosystems to do many things; to purify the air so we can breathe properly, sequester carbon for climate regulation, cycle nutrients so we have access to clean drinking water without costly infrastructure, and pollinate our crops so we don't go hungry.

Answer:

us humans need a balanced ecosystem because its what keeps us alive. when having a balanced ecosystem we have cleaned water, purified air, maintained soil, regulates our climate, recycles nutrients, and provides us with food.

Drag each label to the correct location.
Marizza181 [45]

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

Evaluate the lab and data collected. What type of transport occurred in this lab? Explain your answer, including evidence from y
andreev551 [17]

To know what type of transport occurred the lab and collected data are needed. As they are not present an explanation of the different transport's types, will be given.

Water, proteins, ions, and molecules of different sizes can pass through the cell membrane using different types of transports. The transport that each molecule uses depends on the concentration, size, and polarity.

We can classify the types of transport as active and passive.

Passive transport is the one that does not need energy to happen since the molecules move from a place of high concentration to a one of lower concentration. In this group, we have:

  • Simple diffusion: small molecules in high concentration on one side of the membrane; move to the other side due to the difference in concentration.
  • Osmosis: water passes through the membrane from a place of low concentration of molecules to one of high concentration. Water moves inside or outside the cell to valance the concentration of solutes on both sides of the membrane.
  • Facilitated diffusion: uses proteins to transport large molecules, ions, or hydrophobic molecules from one side to the other. In this type of transport, we have proteins that form channels so those hydrophobic molecules can pass through the lipid membrane, and carrier proteins, which binds to a specific molecule changing their shape and transporting the molecule.

Active transport needs the<em> energy</em> to transport molecules; since it goes against the gradient's concentration. In this group, we have:

  • Sodium-Potassium pump: uses ATP to move sodium outside the cell and potassium to the inside. The ions with this transport go to where they are most concentrated.

In conclusion, there are different types of transport; they depend on the concentration or type of molecule. To find out what mechanism of transport occurred in the lab, look at the components of the experiment and analyze which of these transports could be present.
