B continue to produce oxygen
Explanation:
carbon will not reduce to synthesise sugars
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 C) proximal convoluted tubule
Explanation:
The nephron has the proximal tubule where some water, amino acids and salts which are useful to the body are reabsorbed into the blood capillaries against concentration gradient by active transport.
Thus, the process of selective reabsorbtion takes place in the proximal convoluted tubule
The tilt of the Earth is what causes the seasons...In the summer, the northern pole is pointed closer to the Sun giving the northern hemisphere more daylight hours. The opposite is true during the winter.
