The medium that supports the growth of the widest range of bacteria is the enriched medium.
Agar plate mediums are used to promote the growth of certain bacterias needed for studies. Some bacteria respond well to one medium, but will not grow in another. For this reason, many kinds of mediums exist, including:
MinimalEnriched Selectivedifferentialand many others.
The Enriched medium supports the growth of the widest range of bacteria by containing a wide variety or nutrients and lacking in inhibitors like that of the enrichment medium which would not allow certain bacteria to grow.

A spring with a spring constant of 5 N/m is stretched by John until extended by 1 m. How much elastic potential energy is stored by the spring?
Answer:
0.719m
Explanation:
if the load/ deflection curve of the spring has Force (N) on the y axis and Deflection (m) on the x axis then the slope of the curve is 85 N/m
The energy is the area under the curve ie Base x Height/2
Area (22) = Deflection x (Deflection x 85) /2
Therefore, Def = Sqrt(22 x 2 /85)
Answer:
2.5J
Explanation:
Elastic potential energy = ½ ke²
½ x 5 x 1² = 2.5

1. What
events take place during the cell cycle?
2. How does the structure of DNA
help account for the way in which DNA copies itself?
Answer:
What happens during each stage of the cell cycle?
The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.

Reptilia-
Snake, Alligator, Crocodile, Tortoise
Aves-
Penguin, Sparrow, Eagle, Kingfisher, ostrich
Mammalia-

If you are the first to answer I will mark you as braininess but the answer must be correct
Answer:
As per my full understanding,
There are two main modes of nutrition:
Autotrophic – Plants exhibit autotrophic nutrition and are called primary producers. Plants synthesis their food by using light, carbon dioxide and water.
Heterotrophic – Both animals and human beings are called heterotrophs, as they depend on plants for their food.
WHEREBY: TERMS IN THIS TWO SETS ARE:
Chemohetrotroph. Gets energy from chemicals and carbon from other sources.
Photohetrotroph. Gets energy from light and carbon from other sources.
Chemoautotroph. Gets energy from chemicals and produces its own carbon.
Photoautotroph. Gets energy from light and produces its own carbon.

Is the carbon used in photosynthesis balanced by carbon given off by cellular respiration?
Answer:
Yes.
Explanation:
Plants absorb the CO2 from the air (which we breathe out CO2) and break it into carbon and oxygen. They use that carbon as well as water from the soil to create glucose and ATP and release the oxygen for us to breathe and then we breath the oxygen in and use cellular respiration to create CO2 and energy from the oxygen and our food. It then goes back through the cycle.

The figure below shows what happens to the pH of two solutions when an acid is added. Use the key above the image to answer the questions about the image.
1) Acid
2) Base
3) Experiment 2
Explanation:1) In Experiment 1, when the acid is added, the color of the solution goes from light (suggesting base) to dark (suggesting acid). As such in this case, adding the acid resulted in an ACIDIC solution.
2)The opposite is true in Experiment 2. When the acid is added, the color remains light (suggesting base). As such in this case, the resulting solution is BASIC.
3) Experiment 2 is when the acid is added to buffer the base. A buffer solution, as you remember, is a solution the resists changes to pH when an acid or base is added. Since the addition of the acid in Experiment 2 was done so the pH doesn't change as drastically as in Experiment 1, then we can conclude that it was done to create a buffer solution.
I hope this helps. Let me know if you need any clarification. I am happy to provide it.
A buffer solution is one that can resist changes in pH when an acid or base is added to it.
In Experiment 1, adding an acid to a basic solution would likely result in the solution moving closer to neutral or becoming less basic. So, it might still be slightly basic but less so.
In Experiment 2, adding an acid to a basic solution would likely result in the solution moving closer to neutral or becoming less basic, similar to Experiment 1.
From the information given, it's not possible to definitively determine in which experiment the acid is added to a buffered base. However, a buffer solution is one that can resist changes in pH when an acid or base is added to it. If either of the experiments involves a solution that shows a relatively small change in pH upon adding the acid (compared to what would be expected without buffering), that could be an indication that the acid is being added to a buffered base.
