The nervous system is referred to as a communication system because it carries messages to and from all parts of the body.
Answer:
9:3:3:1
Explanation:
This question involves two different genes coding for height and flower color respectively. The first gene posseses allele T (dominant) and t (recessive) while the second gene possesses allele P (dominant) and p (recessive).
According to this question, two heterozygous tall and purple flowers are crossed i.e. (TtPp x TtPp). Each parent will produce the following gametes combination:
TtPp - TP, Tp, tP, tp
Using these gametes in a punnet square, the following proportion of offsprings will be produced:
T_P_ (tall, purple) = 9
T_pp (tall, white) = 3
ttP_ (short, purple) = 3
ttpp (short, white) = 1
Hence, the ratio of this cross is 9:3:3:1
The complete flower contains both male and female reproductive parts. It has all four parts, that is stamen, pistil, sepals, and petals.
Hence pumpkin is a incomplete flower.
Hi!
So there is a need for scientific names, and I'll tell you why.
Scientists and researchers need to have a "universal language", so they can communicate with others around the world. They use scientific names that normally have Latin origins.
The reason we use common names is so people <em>don't </em>get confused. Normal people won't go around saying they need to walk their canis lupus familiaris. They'd say they need to walk their dog.
Hope this helps ya out fam!
