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.

<span>The salmon is among the most revered of coastal animals, for its cultural and spiritual importance to First Nations, its world-famous tasty flesh, and its role in the historical economy of BC. The most common salmon in our local waters are Chum and Coho. All Pacific salmon species are anadromous, meaning they spend most of their life in the ocean but migrate to fresh water to breed. Consequently they interact with several different ecosystems, and play important roles in terrestrial, freshwater and marine food webs.</span>
When you are finding the kinetic energy, it is best to keep this formula in mind.
Ek = 1/2mv²
Where m is mass and v is velocity. Basically sub the numbers in to find the kinetic energy for each. In this case, subbing all the numbers, the smallest change in kinetic energy is the Lineman with a kinetic energy of just 540N.

Explanation:
<em><u>Our internal body temperature is regulated by a part of our brain called the hypothalamus. The hypothalamus checks our current temperature and compares it with the normal temperature of about 37°C. If our temperature is too low, the hypothalamus makes sure that the body generates and maintains heat.</u></em>
