Answer:
Sleep.
Awaken.
Explanation:
The time and duration of circadian rhythms are regulated by the interactions of PER(period) and TIM(timeless) genes and their proteins. The TIM proteins binds with PER- proteins and the two entered the cell nucleus to set up circadian rhythms.
At midday the two genes becomes active,and their DNAs transcribed to form PER-RNA, and TIM -RNA. These RNAs accumulated in the cell nucleus over some hours.
At dusk(night) the amount of these RNAs reached highest levels.and are translated to the PER and TIM -proteins, which bonded together and moved into the cells nucleus causing sleep in the animals.
Hours to dawn,(morning) the concentration of the two proteins exceeded their limit, and signals is sent to their genes to stop transcription, thus the protein(PER and TIM) synthesis is stopped.
At almost dawn, the PER and TIM proteins disintegrates, the cycle begins again and the individual is awake.
A)Translation is a process by which the sequence of mRNA is converted into a sequence of amino acids of a protien.
Here, you have a case of codominance.
You know that because they tell you that in the presence of both alleles (purple and white) you have a light violet. No one is dominant over the other, both appear as a combination of alleles.
Purple: P
White W
A heterozygous plant has PW alleles.
PW x PW = PP PW WP WW
25% chances of PP (deep purple)
50% chances of PW (ligth violet)
25% chances of WW (white)
Sorry but it's hard to see
Answer:
Explanation:
Herbivores are able to come back easily when they are search for food because their are more than enough food for them to prey on while in lion population, their main feed also take longer period to be produced since they also feed on animal that take time to give birth such as zebras, so they go for other smaller organisms such as waterbucks which take them more time to be completely feeds on to gain required energy.
