Bacteria are like eukaryotic cells in that they have cytoplasm, ribosomes, and a plasma membrane. Features that distinguish a bacterial cell from a eukaryotic cell include the circular DNA of the nucleoid, the lack of membrane-bound organelles, the cell wall of peptidoglycan, and flagella.
Answer:
No
Explanation:
The earth travels in an ellipse, an ellipse is a flattened circle, and the sun is closer to one end of that ellipse and far in another end. That said the Earth is not the same distance as the sun
Answer:
Vmax/ total enzyme concentration (Et)
Explanation:
According to the kinetics of Enzyme catalyzed reaction, the enzyme binds substrate and form the enzyme-substrate complex. The rate constant for this complex formation is K₁.
The enzyme complex later dissociates into the product and the enzyme itself ans the rate constant for this reaction is k₂. An enzyme-catalyzed reaction has the maximum velocity called Vmax.
The k₂ is also known as the turnover number which represents how many substrate molecules are converted into the products.
The mathematical expression for this reaction is the:
Vmax/ total enzyme concentration
Thus, Vmax/ total enzyme concentration (Et) is correct.
Overproduction
Most species produce more offspring than can survive.
Competition
Since living space and food are limited, organisms must compete for the necessities.
Variation
Differences between individuals in a population.
Adaptations
Any kind of inherited trait that improves an organism's chances of survival.
Natural selection
The environment selects organisms with optimal traits to be the parents of the next generation.
Speciation
Over many generations, favorable adaptations accumulate and may result in a new species.
They are at the base of the food chain which makes the diversity possible
