The answer is B. <span>hairy stems (dominant).
</span>If:
H - the dominant allele for hairy stems,
h - the recessive allele for non-hairy stems,
then:
HH - dominant homozygote with hairy stems,
Hh - heterozygote with hairy stems,
hh - recessive homozygote with non-hairy stems.
In autosomal dominant traits, the phenotype is
present if both copies of the dominant allele (H) are present (homozygous
individuals HH) or only one copy of the dominant allele is present
(heterozygous individuals Hh).
In this case all of the batch of tomato plants were <span>heterozygous individuals Hh with hairy stems:
</span>
Parental generation: HH x hh
F1 generation: Hh Hh Hh Hh
The
pancreatic cells act as a self-contained system to secrete insulin in response
to changes in ambient blood glucose concentration, in order to maintain glucose
homeostasis. Glucose is freely taken up into the cell via GLUT transporters, metabolized
to produce ATP, which triggers a cascade of signals within the cell necessary
for glucose-induced insulin secretion.
Answer:
When it multiplies in the nervous system, the virus can destroy nerve cells (motor neurons) which activate skeletal muscles. These nerve cells cannot regenerate, and the affected muscles lose their function due to a lack of nervous enervation.
Explanation:
B) chemical energy is produced in the form of ATP
Transcribing mRNA from DNA happens inside the nucleus and creates the chain of mRNA that is used to translate out in the cytoplasm. When the mRNA reaches the cytoplasm the ribosomes attach they then "read" the mRNA and create the actual protein
