The Dorsal Spines give the fish, "3 Spined Stickleback", because they have hard, spines on their backs. I hope this helps!!!
If you have both parents with long ears and some of the offsprings have short ears, you can say both parents are heterozygous for this. Both have a dominant (long ear), and a recessive allele (short ear).
To prove this, you can draw a Punnett square, and you'll see the probabilities of the offsprings.
Answer:
No
Explanation:
If the earth was tilted, there would be small changes in temperature, but there will be no seasons. The Earth's axis is now inclined at around 24 degrees. This is the main reason for the changing of the seasons. The Northern Hemisphere is in the warm season when the Earth is slanted toward the sun, and the Northern Hemisphere is in the cold season when the Earth is slanted away from the sun. The cycle repeats itself every year because the Earth rotates around the sun at a known and generally constant rate. The sun is higher in the sky during the warm season, making it warmer, and lower in the sky during the cool season, making it colder.
Hope this helps :)

The right answer is C) vector
In molecular biology and genetic engineering, vectors are DNA molecules that allow the propagation of sequences of interest. These are chimeric DNA molecules such as plasmids or artificial bacterial chromosomes, containing an origin of replication and one or more genetic markers. The origin of replication allows the maintenance of the vector in the target cell during generations.
