4 The graph below shows how the activity of an enzyme changes
choli [55]

Answer:

A

Explanation:

A. The optimum pH of the enzyme is 6.6.  - this is true. The optimum pH of the enzyme is where its activity is the highest. On the graph, this is pH 6.6 (activity at 100)

B. The optimum pH of the enzyme is 5.8.  - this is false, the activity of the enzyme peaks at 6.6 (100), at 5.8 the activity is 80

C. The enzyme's activity is greater around pH 8.0 than around  pH 5.0  - This is false, the activity at pH 5 is 50, whereas at around 8 it is 20.

D . The enzyme's activity continually increases as pH increases  from 5.0 to 9.0 - this is false. The activity drops between pH 6.6 and pH 9.

The idea model is used to for relationships between variables, such as time and distance, that can be graphed or be placed into an equation. A physical model, on the other hand, is generally used for objects, such as a cell, to show the various parts and their orientation in respect to each other. A computer model is used to track weather patterns and other factors to predict natural events.

The evolution of similar forms in different lineages when exposed to the same selective pressures is.
luda_lava [24]

The evolution of similar forms in different lineages when exposed to the same selective pressures is<u> convergent evolution. </u>

<u></u>

Convergent or divergent evolution are related to the involved groups, the environments, the selective pressures, and the way in which organisms deal with them to achieve a better adaptation increasing their fitness.

<h3>What is convergent evolution?</h3>

Convergent evolution is the emergence of phenotypical similarities in different groups independently from each other.

Convergent evolution occurs when two or more taxonomic groups share the same traits or characteristics even when they do not share a common ancestor.

Usually, this is a pattern observed in groups that are exposed to the same or similar environmental pressures. The development of these similar phenotypes is related to higher fitness and competitive ability.

The evolution of similar forms in different lineages when exposed to the same selective pressures is <u>convergent evolution. </u>

4. What kind of bond is created by a weak electrical attraction between polar molecules?
Rzqust [24]

Answer:

hydrogen bond

Explanation:

by weak electrical attraction between two polar molecule hydrogen bond is developed between them

the example is water molecule in case of water two water molecules are attracted toward each other by strong hydrogen bond which is developed between highly electronegative oxygen of one water and electropositive hydrogen of another water molecule
