Answer: Austyn's heart rate is up quite a bit compared to Shanice which means either he was working out harder or since he's a male he has a larger heart which need more blood through the body. The heart rate is affected by how hard you work out? The size and possibly the condition of your heart?
Explanation:
Answer:
The dominant curled wing allele is also a recessive lethal.
Explanation:
If we look at the F2 ratio we see that :
curled wings: straight wings= 160:80
=2:1
Hence, if curled wings is considered to be a dominant trait then Curled wings * straight wings
Dd x dd
Punnet square will be as follows :
d d
D | Dd | Dd
d | Dd | dd
Hence in order to get F2
Dd x dd
Punnet square will be the same as above if the F1 cross is Dd* Dd
D d
D DD Dd
d Dd dd
if DD is lethal then the ratio is
Dd:dd=2:1
that is curled wings: straight wings=2:1
Hence, The dominant curled wing allele is also a recessive lethal.
Function of mRNA
The mRNA is formed inside the nucleus in a process called transcription. This mRNA contain codon responsible for the formation of specific type of protein. In translation this mRNA is converted into protein.
Function of tRNA
tRNA is found in cytoplasm and possess amino acids. During translation they attach to the base pair of mRNA with the help of anti-codons.
Formation rRNA:
rRNA is the principle component of ribosome. Ribosome is that organelle which help in attachment of mRNA and contribute in translation.
Answer:
B
Explanation:
Selective Breeding is the process by which organisms choose their mate based off of specific traits.
