Phospholipids have two distinct polarities. The phosphate head is always polar, while the two "tails" it has are nonpolar.
Enzymes, or digestive juices, are secreted by the pancreas into the small intestine. There, it continues breaking down food that has left the stomach. The pancreas also produces the hormone insulin and secretes it into the bloodstream, where it regulates the body's glucose or sugar level.
Answer:
The correct answer would be option C.
Plants evolved different methods to prevent or reduce the effects of photorespiration.
The C3 plants are the most common plants which do not have any special methods or physiology to prevent photorespiration.
The C4 are the plants in which carbon fixation and the Calvin cycle takes place in different cells. Carbon is fixed in the mesophyll cells with the help of PEP carboxylase enzyme. It fixes carbon and converts PEP into oxaloacetate. The Calvin cycle takes place in the bundle-sheath cells.
In contrast, CAM (Crassulacean acid metabolism) plants are those in which carbon fixation and Calvin cycle are separated into time. The carbon is fixed during the night as it helps in reducing the loss of water through transpiration.
The Calvin cycle takes place during the day time in the same cell, that is, mesophyll cell.
Answer:
The correct answer is - option A. 1 (ovary).
Explanation:
Oocytes or egg are produced in the ovaries during the process of the female gametogenesis in female reproductive system. Ovaries are located on each side of the uterus that are oval and small in shape and size and located lower abdomen.
Among other female reproductive organs these are located above others. The ovaries produce oocytes and hormones It is the site at which primordial germ cell (PGC), become primary oocytes.
Thus, the correct answer is - option A. 1 (ovary).
All of these are adaptations used to enable pr otists move except for B.spores , because they are used in asexual reproduction.
HOPE THIS HELPS YOU..!!
