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:
Option A
Explanation:
Only an autotrophic species can convert methane into food.
Deep below the sea, methane and hydrogen sulfide are found in abundance. These gases get mixed into the sea water.
Autotrophic bacteria containing phosynthetic pigments oxidize these dissolved gases thereby producing food.
Hence these autotrophic bacteria’s will be considered as producers as they produce food.
Thus, option A is correct.

The course of basic first-aid will be helpful for me because it prepares me for any kind of medical emergency, I could save lifes with knowing the correct technique.
Explanation:
Every medical emergency in which someone is in real death danger can involves that the patient´s heart stops and he/she stops breathing. On a basic first-aid course the experts teach us what to do in case that happens, in basic words, to keep the person alive until the ambulance arrives to take the person to a hospital.
First aid involves knowing how to cure a simple burnt to having the heart re-animated by using the needed equipment. They teach us how to to a proper CPR in case someone needs it and-more important- how to know when someone needs it.
Also, they prepar us for several emergencies, like choking with food, an allergy episode (how to use the anti-histamine shot), to keep a fracture well until the specialists arrive.
All this information will be helpful for me as a certified trainer because I will be prepared for any situation and most of all, I will be calm.
