A: Netflix's pricing is simple: It's $7.99/month for unlimited streaming, with access to their over 100,000 videos. Netflix also provides a DVD-by-mail add-on service that includes a wider selection of movies and TV shows that is also $7.99/month. So for both DVDs and streaming, it would be $15.98.
Phototropism. Phototropism is a plant's growth response to light. Plants need light to grow. Usually, plant shoots and stems exhibit a positive reaction to light (they grow towards the light source). The ability to grow towards sunlight gives the plants an evolutionary advantage.tudies have shown that plant hormones of the class of auxins play a key role in this directed growth process. Auxin is released into the cells on the plants shady side. There, the hormone stimulates the cell walls to elongate. Also, growth is inhibited on the plant's sunny side.
Plants grow naturally towards the strongest source of light, this is called phototropism. They do this in order to maximise their exposure to the sun and increase the amount of photosysnthesis (and therefore growth). This is a survival mechansim.
