generate energy by photosynthesis
Answer:
d. transcriptional regulation (regulation of whether transcription occurs)
Explanation:
If the product of a gene is not needed, then allowing the transcription of such gene to proceed only to be regulated after or even after translation will result in a mere wastage of resources. It thus means that the resources utilized for transcription has been wasted.
<em>Hence, the correct option is d.</em>
Phase change is the change in state. i.e. water to steam or ice to water
The medulla, pons, and the cerebellum are three main parts of the hindbrain.
Brain is the centre of the nervous system. It is enclosed in the skull cranium. The primary regions of the brain are the forebrain, midbrain and the hindbrain. The forebrain consists of the cerebrum and diencephalon. The midbrain is a small tubular region between the forebrain and the hindbrain. The hindbrain is made up of the medulla oblongata, pons and cerebellum.
Cerebellum is the second largest portion of the brain which helps in maintaining the body's equillibrium, coordinates muscular movements and body posture. Pons is the structure located in the brain stem which relays impulses from medulla to cerebellum and vice versa. Medulla oblongata is the lowest part of the brain stem controlling involuntary reflexes and has the respiratory and cardiac centres in it controlling respiration and heart beats respectively.
Answer:
This demonstrate the transforming principle.
Explanation:
Griffith performed the experiment on the virulent bacteria and non- virulent bacteria. The non- virulent bacteria produce rough colonies and did not cause pneumonia. The virulent bacteria produces smooth colonies that kill the mice and caused pneumonia.
When Griffith mixed the on virulent bacteria and heat killed virulent bacteria he found that the mice were killed. He concluded that there was transforming principle that turns the non- virulent bacteria into virulent bacteria from the heat killed bacteria. Something, has been transferred from the heat killed bacteria to the non- virulent bacteria. Later, he found that dead mice blood sample contained both the non-virulent rough bacteria strains and virulent smooth strains of bacteria.
