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.
C. Z is capital, being a dominant gene. Dominant genes will begin to dominate the gene pool, hence the name given to them. I hope I helped, it’s been forever since I took bio!
Peer review helps scientists do their job better by giving them feedback from others. It also helps control the quality of scientific research and publications.
Answer: West African Coast
Explanation:Hawkins sailed with his cousin (and soon-to-be Sea Dog) Francis Drake to the West African coast in order to capture slaves for trade in the Caribbean and South America, privateering along the way.
Answer: Both Meiosis I and II have the same number and arrangement of phases: prophase, metaphase, anaphase, and telophase. Both produce two daughter cells from each parent cell. However, Meiosis I begins with one diploid parent cell and ends with two haploid daughter cells, halving the number of chromosomes in each cell.
