Answer 1

Answer:

Hii I can't answer all but I can answer two

It is one of the two groups of the carotenoids. The other one is the carotene. After the chlorophyll in the plants these are the most important pigments that are needed for the photosynthesis.

Both are responsible for coloring, as chlorophyll gives plant green color and hemoglobin gives blood red color. 4. Both are considered as fundamental molecule of life because, photosynthesis is the most fundamental function of plant and without chlorophyll it cannot perform photosynthesis.

Answer 2

1. Xanthophylls
2. Both are responsible for coloring
3. Heterotrophs are the organisms that depend on plants or other organisms for their food. ... Saprotrophs are the organisms that obtain their nutrition from dead and decaying organic matter. Saprotrophs secrete digestive juices onto dead and decaying matter to dissolve it and then absorb nutrients from it.
4. Haemoglobin molecule has higher affinity for oxygen and so is an efficient carrier of oxygen as compared to the diffusion process. EXPLANATION: Also "Diffusion" is a slow process and oxygen being less soluble in blood, diffusion fails to carry oxygen to all parts of the body within the right time frame.
5. Osmoregulation is a process that regulates the osmotic pressure of fluids and electrolytic balance in organisms. In animals, this process is brought about by osmoreceptors, which can detect changes in osmotic pressure. Humans and most other warmblooded organisms have osmoreceptors in the hypothalamus. Besides the brain, osmoregulators are also found in the kidneys.
6. The leaves of a healthy plant coated with vaseline will not remain healthy because the vaseline coating will block the stomata. As a result, The plant would not get oxygen for respiration. It would not get carbon dioxide to carry out photosynthesis.
7. Extra air is necessary for our lungs because it keep our lungs from collapsing and becoming useless. This extra air is called as residual volume.
8. Terrestrial organisms take up oxygen from the atmosphere whereas aquatic animals obtain oxygen from water. Air contains more O2 as compared to water. Since the content of O2 in the air is high, the terrestrial animals do not have to breathe faster to get more oxygen.
9. It makes its way through the stomach into the small intestine, where it is digested, after the intake of food by the mouth. In the small intestine the nutrients from the digested food are absorbed into the bloodstream through small pores.
10. The carbon dioxide produced during respiration in the leaves is also used up in photosynthesis. Rather more carbon dioxide is required from the air. Therefore, net gaseous exchange during day time is, oxygen diffuses out and carbon dioxide diffuses in. During night time no photosynthesis occurs in the leaves.
11. Warm-blooded animals such as birds and mammals maintain a constant body temperature by cooling themselves when they are in a hotter environment and by warming their bodies when they are in a cooler environment. Hence, these animals require more oxygen (O2) for more cellular respiration so that they can produce more energy to maintain their body temperature.
12. Thus, it is necessary for them to separate oxygenated and de-oxygenated blood, so that their circulatory system is more efficient and can maintain their constant body temperature.
13. The blood clots if conducting tubes of a circulatory system develops a leak. The platelets will increase, which will minimize the leakage. ... The problem is that if the person doesn't develop with a blood clot, then the medical care is required, otherwise this can lead to death.
