Answer:
The correct options is B.
Explanation:
Evolution has to do with the changes that occur in a particular population of organism as a results of environmental changes and other pressure that the population is exposed to and how the organism adapt to counter the changes.
Out of all the options given in this question, the individual that is most likely to be successful in an evolutionary sense is the one describe in option B. This is because, the organism has a short life span of five days and it left behind ten children that are capable of reproducing. Evolution is a process that occur over a long period of time. So, if it an environmental change occur in the environment where the organism lives, it will be easier for the new generation and the subsequent generations of the organism to adapt to the change.
Those organisms that have long life span will not be able to adapt as easily as the organisms in options B because it will take many years and many generations for them to do that.
Answer:
The trait is Y-linked
Explanation:
The only plausible explanation behind the inheritance pattern shown by the porcupine trait is that it is <u>Y-linked</u>.
<em><u>Y-linked traits are limited to the Y chromosome only</u></em><em>, a sex chromosome that is peculiar to only the male gender. Chromosomally, females are XX while males are XY. Hence, only the male gender has the genetic capacity to inherit the porcupine trait. This is why only the sons of Edward Lambert, and never the daughters, exhibited the trait. </em>
Answer:
Option (C).
Explanation:
Membrane potential may be defined as the difference in the electric potential of the inside and outside of the cell. The resting membrane potential of neuronal cell is -70mV.
Pufferfish contains tetrodotoxin that blocks the voltage gated sodium channels. The movement of sodium ions inside the cell causes the depolarization of cell and makes the cell membrane potential towards more positive. This tetrodotoxin causes the normal resting potential but the cell are not able to depolarize if the stimulus is given to the cell.
Thus, the correct answer is option (c).
