Answer:
Homologous structures.
Explanation:
Homologous structures provide evidence for common ancestry because the organs are similar in position, structure, and evolutionary origin in homologous but different in their function, while on the other hand, the analogous structures indicates that similar pressures on organisms can produce similar adaptations among organisms. so we can say that homologous structure provides evidence for a common ancestor of different organisms.
C - 4
Possible gametes: AV, Av, aV, av
Answer:
In cellular respiration it is a positive term, a process vital to life. But photorespiration is an entirely negative term because it represents a severe loss to the process of using light energy in photosynthetic organisms to fix carbon for subsequent carbohydrate synthesis.
Explanation:
The correct answer is: B) binding to their substrate
The catalytic mechanism of an enzyme starts when the substrate binds to its active site (specific region of an enzyme). There is a theory (lock and key) that explains the mechanism of this binding: the lock is the enzyme and the key is the substrate and only if they fit the enzyme will work. The binding of the substrate to the enzyme causes conformational changes of the enzyme, and as a result, products are formed. The products are then released from the surface of tat enzyme. The enzyme is regenerated for another reaction cycle.
Answer:
the rate of change of velocity with time is called acceleration.
it can also be defined as the increase in velocity per second.
The S.I. unit of acceleration is meter per second square or ms−2.
formula; a = Δv / Δt
where a is acceleration,
Δv is the change in velocity,
and Δt is the amount of time it took for that change to occur.
