Answer:
1. <u>ntrdr</u> --><u> brken</u> --| <u>wag1</u> --> <u>Tail structures
</u>
2. Yes
Explanation:
(1) In this experiment three different genes are present;
1) Wag-1 - promotes production of tail structures
2) brkn gene - inhibits Wag-1 which leads to inhibition or inactive Wag1 gene and there is no tail formation.
3) ntrdr gene - stimulates the activity of brkn gene thus this in turn inhibits Wag-1 gene and results in inhibiting the tail formation.
(2) The ntrdr gene stimulates the brkn gene and active brkn gene inhibits the wag-1 gene. As we know Wag1 gene is essential for tail formation. on removing out ntrdr gene result in inactive gene brkn thus allows the expression of the Wag-1 gene allowing tail growth in dogs.
Eukaryotic cells have a membrane bound nucleus while prokaryotic cells do not. Animal and plant cells are eukaryotic. Animal and plant cells have different organelles.
Answer:
B. Cheetahs
Explanation:
Grass obviously does not hunt, nor do zebras. lappet faced vultures are scavengers, so the cheetah fits all of the above.
