Answer:
B. It allows for genetic variation.
Explanation:
As prophase progresses, homologous chromosomes come to lie side by side and become intertwined rather like a zipper. This process is called synapsis. During synapsis, homologous chromosomes exchange genetic material between one another which allows for genetic variation. This exchange is called crossing over.
Euglena is green in color because of the chlorophyll that is contained in the chloroplast of that organism and the body structure that is located at its base is known as flagellum
.
Explanation:
Euglena are species that are found in the fresh and salt water. They are abundantly found in inland waters where they manage themselves to bloom in large amount and color the water surface of ditches and ponds green.
This green color which them form are mainly due to the chlorophyll that is contained in the chloroplast of the organism. chlorophyll is known to be the pigment that is responsible for the green color.It is the cause for the green color in this case too.
Euglena contains a specialized body structure which is located at the base of the tail by which it manages to move.
This specialized structure is known as Flagellum.
Answer:
RNA polymerase
The main enzyme involved in transcription is RNA polymerase, which uses a single-stranded DNA template to synthesize a complementary strand of RNA.
Explanation:
Answer:
Un depredador y sus presas coevolucionan, el depredador se vuelve más eficiente en perseguir y matar a sus presas y las presas dearrollan nuevas defensas y formas de escape. La coevolución impone presiones selectivas. Éstas a su vez llevan a una carrera armamental de adaptaciones mutuas progresivas
Explanation:
