Answer:
Option-B
Explanation:
Phototropism refers to the movement of plants in response to light. The mechanism of phototropism involves the photoreceptors which respond to a different wavelength of light: the phytochromes to red light, cryptochromes to blue light and the phototropin to the UV light.
Plants integrate the signals obtained from these receptors and then activates the gene which will be involved in the phototropism.
The gene could be the production of the auxin hormone and the PIN proteins which helps in the distribution of the auxin in the plants. Due to the production of this hormone and its distribution in the shoot, the grass tips bend towards the light.
Thus, Option-A is correct.
Answer:
It is producer! because thats what produces everything and it needs energy to be able to do that.
The question is incomplete as the options are not provided which are:
RNA replicase is present in the viral capsid.
The RNA genome is of the plus sense and RNA replicase is present in the viral capsid.
The new bacteriophage is a retrovirus.
The RNA genome is of the plus sense.
Answer:
The RNA genome is of the plus sense and RNA replicase is present in the viral capsid.
Explanation:
The bacteriophage is the virus particles which are composed of the genetic material enclosed in the Capsid protein. The Bacteriophage virus infects the bacteria and uses their replication machinery to replicate themselves.
In the given question, all the proteins along with RNA for translation or ribosomes is provided. The single-stranded RNA is first their genome copied by the RNA replicase and the positive strand, therefore, acts as the mRNA. This mRNA is then translated into the protein sequence and a new virion is produced.
Thus, the selected option is correct.
