The cell density (cells/mL) = 15× 10^6 cells per mL.
Calculation of cell densityThe doubling time of culture = 2 hours
The cell density after 2 hours = 3 x 10^6 cells per mL
Since the dilution did not affect the lag phase and exponential growth rate, the cell density after 10 hours is calculated below:
2 hour = 3 x 10^6 cells per mL
10 hours = X
Cross multiply,
[tex]x = \frac{10 \times 3 \times10 {}^{6} }{2} [/tex]
[tex]x = \frac{30 \times 10 {}^{6} }{2} [/tex]
X= 15× 10^6 cells per mL
Therefore, the cell density in (cells/mL) after 10 hours = 15× 10^6 cells per mL.

why are frogs and toads different explain using complete sentances.
Answer:
Frogs have smooth or slimy skin that is moist, whereas toads have thicker, bumpy skin that is usually dry. All toads are poisonous, while frogs are not.
Answers and Explanations:
Frogs and toads actually have a lot of differences, granted they look alike.
Frogs:
Frogs tend to have much longer legs than their body, which are made for jumping. They also tend to have much smoother, slimier skin. Frogs also tend to have longer front legs as well. Not only that, but frogs prefer to hop rather than walk. Frogs also sometimes have bigger eyes, unlike a toad. Because frogs need to stay slimy and smooth, frogs are most commonly and only found in areas where there is water, or where it is very damp.
Toads:
Toads tend to have shorter, more stubby front and back legs. Toads also tend to have more dry, wart-like skin. They also like to crawl more than hop around. These amphibians also tend to have eyes that are not as big as a toad. You are also more likely to see a toad than a frog because they tend to wander away from water, unlike a frog.

Why too much respect for the feelings of those involved in conflict may hamper your attempt to effectively resolve it?
From what we know, we can confirm that having too much respect for the feelings of those involved in a conflict will hamper your attempt to resolve it by generating bias.
How does bias hamper your ability to resolve the conflict?In order to effectively resolve a conflict, all parties involved must make certain sacrifices and come to an agreement. This agreement should benefit all parties involved to some extent. Having too much respect for the feelings of one person or group would create a bias in which you are more likely to favor that group over the other.
Therefore, having too much respect for the feelings of those involved in a conflict will hamper your attempt to resolve it by generating bias that affects your ability to make a fair decision.

Plants perform photosynthesis and respiration. Dead plants are broken down and become part of the soil. Which of the following matter do plants help to cycle through ecosystems? A, B, or C
a. carbon, oxygen, and nitrogen only
b. carbon only
c. carbon, oxygen, nitrogen, and water
Answer:
Its C
Explanation:
If you are allowing plants to decompose when dead that will add nitrogen to the ecosystem. Plants need nitrogen for photosynthesis. Decomposition and carbon dioxide provide carbon. They expel oxygen. I would say they provide all between dying (decomposition) and respiration.

Consider a flower population that produces different sizes of blooms and depends on bees for reproduction. Large blooms attract larger bees; small blooms attract smaller bees. Describe how changes in the bee population might lead to disruptive, stabilizing, and directional selection in the flowers.
The parallel evolution of flowering plants and pollinators represents a case of coevolution. It may lead to different types of natural selection.
Disruptive, stabilizing, and directional selectionDisruptive selection is a type of natural selection that favors extreme phenotypes (in this case, flowers too small or too big).
Stabilizing selection is a type of selection that leads to decreased genetic variation (in this case, all red flowers to attract pollinators)
Finally, directional selection is a type of natural selection where an extreme phenotype can be favored (in this case, taller plants to be noted by bees).
