<span>Is a group living things must be able to do all of the following except
A??</span>
Answer:
light is the independent variable, height of the plant is the dependent variable. Dependent is the effect that based on the independent.
Explanation:
lets break it down. 1) you want to know the effect of something you apply from one thing to another. Let say, if you grow your plants under the sunlight, the plants grow taller. In this case, the sunshine is the independent variable whereas the height of the plant/how tall it can grow is the dependent variable. 2)NOW, before i give the answer. The design of the question is not good for high school students. i think your teacher thinks "light" is the independent variable. 3)However, the question contains confounding variables in it because different lights might produce different effects to the height of the plants. If you want to test if plants are exposed to light grows taller than plants do not expose to light, then you should have all the lights are the same. 4) So, all the plants should be exposed to one certain light to avoid confounding. Confounding means that either red light and sunlight are both produce the same effect whereas the other colors do not help the plants to grow taller. 5)Your teacher should test one light at a time. So, if he is testing with all different colors of light, then light is the independent variable, and height of the plant is the dependent variable.
Answer:
pfu/ml
Explanation:
Given -
Bacteriophage dilution 
ml
Volume of bacteria and plate with top agar 
ml
Number of plaques 
pfu
Dilution (d) 
Final concentration of phage stock is equal to
Where pfu is the count of plaques
d is the dilution and v is the volume
Substituting the given values, we get -
pfu/ml
Some scientists are studying a newly discovered microbe and determine that it consists of a single cell, lacking a nucleus. this organism could be <u>a bacterium.</u>
<u></u>
<h3>What do you mean by bacterium?</h3>
- Any of a large group of one-celled organisms that reproduce by fission or by generating spores, lack a cell nucleus, and occasionally cause disease.
- They are the most prevalent life forms on Earth, present in all living organisms as well as all climatic conditions.
<h3>What can be discovered in bacteria?</h3>
- Its gel-like matrix, which also contains other cell components like ribosomes, chromosomes, and plasmids, is made up of water, enzymes, nutrients, waste products, and gases.
- The cytoplasm and all of its elements are enclosed by the cell membrane.
- Bacteria do not have a nucleus that is contained in a membrane like eukaryotic (true) cells do.
