Describe regeneration carried in multi cellular organisms like hydra |
| Answer» Regeneration is the ability of a living organism to regrow the part of the body that gets broken off or cut. Regeneration is not the same as reproduction, since the organism would not depend on being cut to reproduce. For example, if a hydra breaks horizontally into two parts, then the upper part having the mouth and tentacles regenerates to form the lower part. While the lower part of the original hydra without mouth and tentacles regenerates to form the mouth and tentacles. Thus, two complete organisms are formed from the two cut parts. | |

Function of thyroxine, adrenaline and progesterone |
| Answer» 1) Thyroxine is the principal hormone produced by the thyroid gland. It promotes protein synthesis (blending) and growth, and also helps regulate the body\'s metabolism.2) Adrenaline is a survival hormone. It helps us be fast or strong under threat. When humans encounter danger, we have two options: fight off the predator, or run for the hills. Each of these responses requires muscle strength. When our amygdala senses danger, it reaches out to the hypothalamus, Adrenaline then triggers the physiological changes our body will need to attack, defend, or run away.3) Progesterone is one of the hormones in our bodies that stimulates and regulates various functions. Progesterone plays a role in maintaining pregnancy. The hormone is produced in the ovaries, the placenta (when a woman gets pregnant) and the adrenal glands. It helps prepare your body for conception and pregnancy and regulates the monthly menstrual cycle. It also plays a role in sexual desire. | |

Why sun see red during sunrise or sunset |
|
Answer» Also during sunrise and sunset the sun is very far away from us than in noon when the sun is overhead When the sun is near horizon , the Ray\'s of light enters he atmosphere in an inclined angle .so most of the light is scattered and does not reaches our eyes. Red colour being least scattered reaches our eyes and and the sun appears red to us. We see red light during sunset or sunrise because during sunset the rays have to travel a big part to become visible to us and as we know red colour has most wavelength compared to others.... Due to scattering of light. Blue light is scattered all we get is red colour. |
