Scientists have discovered homeotic genes in many kinds of organisms, including fruit flies, mice, and humans. These homeotic ge
love history [14]

Answer:

D

Explanation:

The presence of homeotic genes shows that all of the listed organisms (mice, flies, humans etc) all evolved from a common ancestor.

(A) is wrong as the evidence of the same gene existing in vastly different species shows the evolutionary relationship between these organisms.

(B) is wrong as there is insufficient evidence to prove that flies are the precessor of humans. We do know that flies and humans have evolved from a common ancestor though.

(C) is non-conclusive as the passage said nothing about the gene allowing the species to have a higher chance of surviving and reproducing. Hence, an errornous claim.

(D) is the correct answer as from a common ancestor, all of the listed organisms undergo and accumulates mutation, undergoes selective pressures that resulted in divergent evolution (aka branching evolution that results in many noval species forming) after millions of years.

Which of the following is maintained across the terminals of a battery?
astraxan [27]

Answer:

Option D, both A and B

Explanation:

The potential difference is created across a battery (between its two terminal –one positive and the other one negative) when work is done to move a charge from one point to another. This potential difference is measured in volts. 1 volt is the potential difference between two points when one joule of potential energy is spent to move a charge of one coulomb from one point to the other.  

Voltage drop across a circuit is the amount of electric current lost due to resistance/ impedance with in the cables of the circuit.  

Hence, both potential difference and voltage drop occurs across the circuit,  

Option D is correct.
