Homologues are chromosome pairs of the same length, centromere position, and staining pattern with genes for the same characteristics at corresponding locations. One homologous chromosome is inherited from the organism's mother, the other from the organism's father during sexual reproduction. The crossing over, or synapse, occurs during meiosis, which is the process of gamete formation.
Answer:
Golgi bodies or Golgi apparatus both are correct
Explanation:
Answer:
The correct answer will be options-B and D
Explanation:
The studies on the history of origin and evolution of life on Earth shows that all the organisms have evolved from a common descendant. This indicates that they possessed the same chemical-genetic or heredity molecule called Nucleic acid whether DNA or RNA.
DNA acts as the universal genetic material as it is present in all organisms except few. The process related to the DNA molecule is the same in all the organisms.
Since in the given question, the transfer of genes to plants via <em>Agrobacterium</em> and then the expression of the gene in plants shows that the passing of DNA has no barrier as DNA is the genetic material and the enzyme RNA polymerase recognized the gene which could help produce the mRNA from the gene.
Thus, options-B and D is the correct answer.
Answer:
we use the equation
kinetic energy (Ek)=1/2*mv²
when we rearrange the equation we get speed (v) as
root of 2Ek/m=speed
so root of 2(500)/2=10 root 5m/s or 22.36m/s
