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.
DNA is the genetic material, in a double helix shape, used to make proteins. RNA is the single helix molecule that actually turnd DNA instructions into proteins. ATP is the main storage unit of chemical energy in the cell. All this is a basic comparison you should have learned in 9th grade Biology.

Answer:
The transfer pattern of an X-linked inheritance can be either X-linked dominant or X-linked recessive.
Explanation:
X-linked inheritance is the term that refers to a gene capable of causing a specific characteristic or disorder and is located on the X chromosome. During the transmission of genetic material for the formation of another living being, this gene can be transmitted through the transmission standards known as X-linked dominant or X-linked recessive.
X-linked dominance inheritance occurs when the dominant gene is transmitted on the X chromosome, while X-linked recessive inheritance occurs when the recessive gene is carried on the X chromosome.
