Answer: Ethylene Gas
Explanation: Ethylene Gas Can be Used to Regulate Fruit Ripening Ethylene is a gas and is known as the “fruit-ripening hormone.”
Answer:
they are called autotrophs...
Explanation:
Autotrophs, which also called producers are the organisms which are able to produce the more complex substances like proteins fats and carbohydrates from what is around them (the sun and also carbon dioxide and water...)
HOPE THIS HELPS!!
Answer:
All the options are correct regarding hypothalamus.
Explanation:
The hypothalamus is the part of the forebrain. The diencephalon is divisible into 2 parts - thalamus and hypothalamus. It regulates various functions of the body.
This is the thermoregulatory center of the body. It gives the signal to sweat during a hot environment and shiver in winter. This maintains the water balance in the body by stimulating the secretion of ADH hormone in the kidney.
Hypothalamus also has regulated anterior pituitary hormone secretion. Thus it controls the endocrine secretion of pituitary glands.
This plays an important role in hunger and thirst. The feeding habits like the licking of lips, swallowing, and salivating by seeing delicious foods is due to hypothalamic activities.
The behavioral activities of individuals influenced by the hypothalamus. It is worked along with the limbic system of the brain. The behavioral activities include fear, punishment and sexual desire.
Hey there..
If I'm correct the guidelines are: reuse, reduce and recycle.
Hope it helps :)
Answer:
For both actin and microtubule polymerization, nucleotide hydrolysis is important for decreasing the binding strength between subunits on filaments.
Explanation:
Cytoskeletal filaments are common to eucaryotic cells and are impotartant to the spatial organization of cells. Intermediate filaments provide mechanical strength and resistance to shear stress. Microtubules determine the positions of membrane-enclosed organelles and direct intracellular transport. Actin filaments determine the shape of the cell's surface and are necessary for whole-cell locomotion. A large number of accessory proteins are present that link the filaments to other cell components, as well as to each other. Accessory proteins are essential for the assembly of the cytoskeletal filaments in particular locations, and it includes the motor proteins that either move organelles along the filaments or move the filaments themselves.
Actin filaments and microtubules are assembled with expenditure of energy i.e the ATP/GTP tightly bound to actin/tubulin is irreversibly hydrolyzed to ADP/GTP during the assembly process, and liberation of Pi in the medium occurs subsequent to the incorporation of subunits in the polymer. Pi release acts as a switch, causing the destabilization of protein-protein interactions in the polymer, therefore regulating the dynamics of these fibres. The progress is made in four areas: the chemistry of the NTPase reaction; the structure of the intermediates in nucleotide hydrolysis and the nature of the conformational switch; the regulation of parameters involved in dynamic instability of microtubules; and the possible involvement of nucleotide hydrolysis in the macroscopic organization of these polymers in highly concentrated solutions, compared with the simple case of a equilibrium polymers.
