This is a true statement. Viruses in the same family have the same types of genomic structure. This allows them to enter a cell and replicate their information with the host much easier than if they did not share similar types of internal information.

(Experiment 1: Diffusion through a liquid) Does the rate of diffusion correcspond with the molecular weight of the dye?

saveliy_v [14]

The answer to this question would be: False

The rate of diffusion should not be influenced by molecular weight. Big molecule might not be able to pass the membrane though.
Diffusion happens when there is a difference/gradient in the concentration of the molecules. If the difference is higher, then the diffusion rate will be increased.

uhm i have 5 questions due in an hour so please help. It's 45 points and they're all abt biology btw~

Mariulka [41]

Answer:

the point of science is to disprove hypothesis so having a hypothesis that doesn't allow that to happen is not good science

2. they don't fit in our mouths so are a trait from when we had larger jaws

3. bones of your lower jaw, middle ear and voice box (they aren't actually gills fyi, they just look like them)

4. likely yes as their bones were hollow but likely only able to fly short distances, the thought was that they couldn't do their size and weight but with hollow bones they were able to like a quail would

5. no because they could be sister taxa, you would have a hard time proving exactly that this new fossil is the common ancestor that birds came from to replace the old hypothesis (guess) of which one did.

What is the job of a nucleus cell

11Alexandr11 [23.1K]

Answer:

This organelle has two major functions: it stores the cell's hereditary material, or DNA, and it coordinates the cell's activities, which include growth, intermediary metabolism, protein synthesis, and reproduction (cell division). Only the cells of advanced organisms, known as eukaryotes, have a nucleus.

3. test the hypothesis

4. make observations

5. analyze the results and

make a conclusion

6. ask questions

Pairs

A. Bread, when kept in the open for a

long time, shows the presence of mold.

B. What causes mold growth on bread?

C. Changes in temperature may affect

the growth of mold on bread.

D. Keep the bread in different locations,

changing the temperature at each location.

E. Increased temperature leads to the

growth of mold.

F. Make a presentation of the data, and

explain it to the class.

Explanation:

<h3>ANSWERS :</h3>

1- C ( this is an assumption; a hypothesis is always based on an assumption.

2- F ( this states to share the results with other classmates).

3- D (this is a description of an experiment you could conduct; you test a hypothesis (usually) by conducting an experiment.

4- A (this is something you could observe during the experiment, therefore it is an observation).

5- E (this sentence is a conclusion).

6- B (This is an actual question)
